Chairperson and Chief Executive Officer's Joint Review

As we move into the second half of 2021, we look forward to capitalizing on the efforts of the team throughout the first six months of 2021. We have generated more data expanding our unique understanding of mechanisms of host-microbe interactions and are seeing the benefits in our clinical programs while we continue to drive research through our proprietary MicroRx® platform. This work has allowed us to discover new therapeutic possibilities in disease such as Parkinson's, and demonstrate potential of our Live Biotherapeutics alongside new modalities such as CAR-T. Alongside the continued push to bring our Live Biotherapeutics to an approval in oncology, 4D pharma achieved a significant milestone at the beginning of the year following our listing on NASDAQ.

Building the oncology franchise

We continue our commitment to oncology, building a strong understanding of the utility of our Live Biotherapeutics in this field. In particular recognizing the value of a therapeutic which has little or no side effects to combination with existing therapies in the fight against cancer while many other combination treatments currently evaluated in immune-oncology increase toxicity.

With our lead oncology candidate MRx0518, we have built on our ongoing work with MSD (Merck & Co.) and its anti-PD-1 immune checkpoint inhibitor (ICI) Keytruda® (pembrolizumab), announcing a new clinical collaboration and drug supply agreement with Merck KGaA and Pfizer and their anti-PD-L1 ICI Bavencio® (avelumab). In contrast to the ongoing study with Keytruda in ICI-refractory patients, the new Bavencio collaboration takes MRx0518 into earlier lines of treatment, and expands our clinical portfolio targeting the PD-1 axis.

Under the collaboration we will conduct a clinical study to evaluate MRx0518 in combination with Bavencio as a first-line maintenance therapy for urothelial carcinoma, a common form of bladder cancer. Bavencio is the first and only ICI approved in this setting, and we are excited to commence this fourth clinical study of MRx0518 before the end of 2021.

In addition, we announced progress updates for the three ongoing clinical studies of MRx0518 - in combination with Keytruda in patients with solid tumors refractory to prior ICI therapy; as a neoadjuvant monotherapy; and in combination with radiation prior to surgery for pancreatic cancer. These studies continue to progress well, giving more insights into the biological mechanisms of MRx0518 and its activity on the patient immune system, potentially allowing us to understand which patients may benefit most from MRx0518 in combination with ICIs like Keytruda and Bavencio.

After the period end, in September, 4D pharma presented new data from the Keytruda combination and neoadjuvant monotherapy studies at the European Society for Medical Oncology (ESMO) Congress. The ESMO 2021 posters can be accessed via the Posters & Publications page of our website at https://www.4dpharmaplc.com/en/newsroom/posters-and-publications. The new data includes tumor immune biomarkers associated with response to the combination with MRx0518 and Keytruda, which is an exciting proposition we look forward to investigating further as we continue to progress MRx0518. This is supported by additional data for MRx0518 as a monotherapy, providing further evidence of immune activation by our oral Live Biotherapeutic, including positive changes in prognostic indicators predictive of response to immunotherapy. These data continue to deepen our understanding of the activity of MRx0518 on patients, and will help inform engagement with regulatory authorities and clinicians as we continue to develop this leading immuno-oncology Live Biotherapeutic.

The main focus of our work in oncology at this time is the preparation of a pivotal development program for MRx0518 in an oncologic indication.

Through our clinical programs and research, our work in oncology illustrates the potential of the MicroRx® platform to expand 4D pharma's leadership in oncology.

Alongside our work in solid tumors, 4D also continues to push forward in identifying new LBP candidates in additional oncology settings, such as CAR-T. 4D pharma recently published pre-clinical research relating to second-generation oncology LBP MRx1299 in the respected peer-reviewed journal Nature Communications. The research demonstrates the ability of the bacterium Megasphaera massiliensis and its short chain fatty acid (SCFA) metabolite pentanoate to enhance the anti-tumor activity of cytotoxic T lymphocytes (CTL) and Chimeric antigen receptor T cell (CAR-T) therapies in animal models of cancer.

Blautix® - a leading late-stage LBP candidate

IBS remains a misunderstood disease and not easily characterized. In the US, as many as 35 million people report IBS symptoms, with 60-70% being women. IBS remains a disease with significant unmet need. Current treatments target sub-type specific symptoms (diarrhea or constipation) but, due to side effects and sub-optimal efficacy, patient satisfaction and compliance remains an issue.  Further, there currently is no therapeutics approved for patients with fluctuating or mixed symptoms, known as IBS-M.

Following publication of topline efficacy and safety results from our Phase II study of Blautix® in irritable bowel syndrome with constipation (IBS-C) and with diarrhea (IBS-D) in October 2020, important additional data was presented at Digestive Disease Week (DDW) in May 2021. The DDW 2021 posters can be accessed via the Posters & Publications page of our website at https://www.4dpharmaplc.com/en/newsroom/posters-and-publications . A key finding from sub-group analyses was an unusually high placebo response rate in patients in the UK and Ireland which negatively impacted the topline results. Conversely, we saw an enhanced effect in the US population in both IBS-C and IBS-D.

In agreement with regulatory guidelines and key opinion leader feedback, the positive Phase II data provides a clear path forward for the development of Blautix as a novel treatment for IBS with the potential to be a single, safe, effective therapeutic able to address multiple subtypes of IBS. We have engaged with the US FDA regarding plans for pivotal development, and discussions are ongoing with multiple potential partners for the program.

MRx-4DP0004 - Systemic immune activity via the gut

MRx-4DP0004 is in an ongoing Phase I/II first-in-human clinical trial in patients with partly controlled asthma, as an add-on therapy to their long-term maintenance asthma medication.

In June we announced the completion of target enrolment of 30 patients in Part A of our Phase I/II randomized, placebo-controlled study of asthma candidate MRx-4DP0004.  Part A of the trial primarily assesses the safety and tolerability of MRx-4DP0004, as well as biomarker signals of activity relevant to asthma. We expect to announce top line results later in 2021.

Leveraging the gut-brain axis

As accumulating evidence points towards the gut-brain axis and the role of the microbiome in conditions of the central nervous system (CNS), we are excited to continue to push forward in this field.  In April, the company announced our collaboration with Parkinson's UK, to establish a Patient Advisory Board (PAB) of people living with Parkinson's disease. The PAB provides valuable patient perspectives as we continue to advance candidates MRx0029 and MRx0005 towards a first-in-man study in patients with Parkinson's disease expected to begin in 2022.

Corporate activity

The NASDAQ is the premier exchange for biotechnology companies worldwide, giving companies global reach and visibility within the healthcare investment ecosystem. Achieving a listing on NASDAQ has been a strategic objective for 4D pharma's continued growth and success moving forward.

In March 2021 we met this transformational milestone, as we listed 4D pharma American Depository Shares (ADSs) on the NASDAQ exchange in the United States following the completion of our merger with special purpose acquisition company (SPAC) Longevity Acquisition Corporation.

In conjunction with the SPAC merger and NASDAQ listing we conducted a fundraise which together provided the company with approximately $42 million of additional capital. In doing so we began to strengthen our international investor base and put 4D pharma in a strong financial position to execute across our pipeline.

Further, after the period end in July, we also announced a credit facility with Oxford Finance LLC, that provides 4D pharma with up to $30 million of capital across three tranches, of which the first tranche of $12.5 million was received upon closing. The facility diversifies and strengthens the company's capital structure with a well-respected specialty finance firm in the life sciences field. The additional funds further extend our cash runway beyond additional potentially transformative development milestones.

In addition to strengthening our financial position, we also strengthened our leadership team.  In March we welcomed Paul Maier as a Non-Executive Director who will also serve as a financial expert under SEC and NASDAQ rules. Paul brings over 25 years of operational and financial management experience in the life sciences industry, and his experience has been a valuable addition to our Board of Directors.

It was with great sadness that we announced the passing of John Beck in July of this year, who had served as Chief Financial Officer with the company since March. John was greatly respected within the life sciences industry and brought 30 years of finance experience to our team. His significant contributions to the company during his time with us have been highly valuable, and we hope to carry his legacy forward by building upon the strong foundations he helped to lay as 4D pharma entered a new era as a US-listed entity.

Conclusion

The first half of 2021 has been a significant period for 4D pharma. Our dual listing on NASDAQ raised our international profile and, using this as a platform along with new funds at our disposal, we look ahead to a period rich in clinical catalysts across our pipeline of Live Biotherapeutic Products taking the microbiome beyond the gut, including clinical readouts and the commencement of new studies across multiple programs. Highs and lows in the broader microbiome space have created mixed feelings towards microbiome therapeutic approaches - we are confident 4D pharma's differentiated, mechanism-driven approach is poised to deliver.

Notes to the Interim Financial Report

For the six months to 30 June 2021

1. Basis of preparation

The Group's half-yearly financial information, which is unaudited, consolidates the results of 4D pharma plc and its subsidiary undertakings up to 30 June 2021. The Group's accounting reference date is 31 December. 4D pharma plc's shares are quoted on the AIM market of the London Stock Exchange (AIM) as DDDD and as American Depositary Shares (ADSs) on NASDAQ as LBPS with each ADS representing 8 Ordinary shares.

The Company is a public limited liability company incorporated, registered and domiciled in the UK. The consolidated financial information is presented in round thousands of Pounds Sterling (£000).

The financial information for the six months ended 30 June 2021 and 30 June 2020 is unaudited.

Full audited financial statements of the Group in respect of the period ended 31 December 2020, which received an unqualified audit opinion and did not contain a statement under sections 498(2) or (3) of the Companies Act 2006, have been delivered to the Registrar of Companies.

The accounting policies used in the preparation of the financial information for the six months ended 30 June 2021 are in accordance with the recognition and measurement criteria of International Financial Reporting Standards as adopted by the UK (UK IFRS) and are consistent with those which will be adopted in the annual financial statements for the year ending 31 December 2021.Whilst the financial information included has been prepared in accordance with the recognition and measurement criteria of IFRS, the financial information does not contain sufficient information to comply with IFRS.

4D pharma plc has not applied IAS 34 'Interim Financial Reporting', which is not mandatory for UK AIM listed groups, in the preparation of this interim financial report.

2. Going concern

The Group and parent company are subject to a number of risks similar to those of other development stage pharmaceutical companies. These risks include, amongst others, generation of revenues in due course from the development portfolio and risks associated with research, development and obtaining regulatory approvals of its products. Ultimately, the attainment of profitable operations is dependent on future uncertain events which include obtaining adequate financing to fulfil the Group's commercial and development activities and generating a level of revenue to support the Group's cost structure.

The Directors have prepared detailed financial forecasts and cash flows looking beyond 12 months from the date of the approval of these results. In developing these forecasts, the Directors have made assumptions based upon their view of the current and future economic conditions that are expected to prevail over the forecast period. The Directors estimate that the cash held by the Group together with known receivables and the income of $12.5 million from the first tranche of the loan (issued by Oxford Finance SARL) in July 2021 will be sufficient to support the current level of activities into Q4 2022; accordingly, the accounts have been prepared on a going concern basis.

3. Taxation

The tax credit is made up as follows:

4. Loss per share

(a) Basic and diluted

The basic and diluted loss per share are the same as the effect of share options is anti-dilutive.

(b) Adjusted

Adjusted loss per share is calculated after adjusting for the effects of non-recurring costs arising on the inclusion of the fair value adjustment from the issue of warrants, options and shares as part of fundraising activities.

Reconciliation of adjusted loss after tax:

5. Share capital

The balances classified as share capital and share premium include the total gross proceeds (nominal value and share premium respectively) on issue of the Company's equity share capital, comprising 0.25 pence ordinary shares.

On 22 March 2021 the Company completed the merger with Longevity Acquisition Corporation and listed on NASDAQ. Since Longevity is a cash shell with no future trade or income it did not qualify as a business and is not subject to the treatment for business combination under IFRS 3; as such the transaction has been treated as the issue of shares for cash.

In connection with the merger, and in addition to the shares issued above, the Company also issued New Warrants convertible into ordinary shares. These were comprised of: 4,320,000 outstanding warrants that were previously issued by Longevity to holders of Longevity shares at the time of the Longevity IPO and which will be converted into warrants to purchase up to 16,268,040 ordinary shares, payable in ADSs; warrants to be issued to the backstop investors to acquire up to 7,530,000 ordinary shares following completion in connection with the backstop arrangements; and, an option to acquire up to 2,892,096 ordinary shares for Cantor Fitzgerald, in its capacity as underwriter to Longevity at the time of the Longevity IPO. If all the New Warrants are exercised, the Company would receive approximately $29 million of capital.

6. Subsequent events

Loan finance

On 29 July 2021 the Group entered into a loan agreement with Oxford Finance SARL for up to $30 million maturing on 1 July 2026, with the first tranche of the loan extending the Group's cash runway until Q4 of 2022 if fully utilized.

The loan is payable in three tranches; the first $12.5 million was received on signature with further tranches of $7.5 million on achieving certain milestones and a further $10 million available at the discretion of the lenders.

Interest will be charged on the loan at 8.15% plus the greater of the 30-day US Dollar LIBOR rate and 0.1% throughout the term of the loan. Interest only monthly payments will be made until either 1 September 2023 or 1 September 2024 if certain milestones are met.

A 6.0% or 6.5% final payment fee will be charged, the latter being dependent on the extension of the interest only period with discounts to this fee to 3%, 2% or 1% if the loan is repaid before the maturity date depending on certain criteria. 

In addition to the interest and final payment fee, warrants were issued for 212,568 shares at an exercise price of $1.18. Further warrants become available on drawdown of loan tranches at a rate of 2% of the loan value with an exercise price based on the lower of the preceding day's share price and the 10-day average share price prior to the further loan. All warrants have a five-year exercise period from the date of issuance.

The loan includes various customary covenants limiting the Group's ability to perform certain functions that may affect the recoverability of the loan, as well as providing penalties and repayment provisions in the event of a default. A copy of the loan agreement and further details can be found as an exhibit to our recent F-1 filings with the SEC, a link to which is provided on our website.

7. Principal risks and uncertainties

The Company operates within a complex regulatory environment, which is subject to change. The nature of LBP development exposes the Company to a number of additional risks and uncertainties which could affect its ability to meet its strategic goals, its business model and its operating environment.

The Company sets out its Company and market specific risk factors on a continual basis in its Annual Reports, which supplement the risk factors set out in its original admission document (which is available on the Company's website). The Company's most recently published Annual Report is that for the year to 31 December 2020, which is also available on the Company's website: https://www.4dpharmaplc.com/en/investors/reports-presentations. A more detailed list of risk factors can be found in the Company's regulatory filings with the SEC which can be accessed through the Company website: https://www.4dpharmaplc.com/en/investors/sec-filings. The risk factors listed in these sources are not necessarily comprehensive, but represent, in the Board's view, the principal risks and areas of uncertainty that the Company currently faces. Shareholders and potential investors should take independent advice if they wish to consider the suitability of these risks with regard to their own particular circumstances and investment criteria.

Management's discussion and analysis of financial conditions and results of operations

Key performance indicators

We track a series of metrics focussed primarily on science and product development whilst ensuring that the business maintains both sufficient resources and effective allocation of those resources to achieve our strategic goals. The Board and management of 4D monitor the following metrics as an indicator of how we are progressing towards the goal of advancing our Live Biotherapeutic programs:

1.   Successful clinical trials - We are a drug development company and will realize long-term value by successfully progressing its candidates through the clinic to registration and approval. For the six months ended 30 June 2021, we had completed two clinical trials through Phase I and one through Phase II. For the six months ended 30 June 2020, we had two clinical trials completed through Phase I.

2.    Clinical trials initiated by phase - Clinical trials are essential in converting the productivity and potential of our MicroRx platform and early-stage research into long-term value. By the end of the six months to 30 June 2021, we had initiated seven clinical trials including three Phase I, two Phase I/II and two Phase II trails. There were six clinical trials that we had initiated by the end of the six months ended 30 June 2020 of three Phase I, two Phase I/II and one Phase II trial.

3.   Strategic collaborations - Collaborations enable us to realize the potential of our platform, leveraging the complementary expertise of our partners. In December 2020 we became an industry partner of the PPMI, a longitudinal study sponsored by The Michael J. Fox Foundation for Parkinson's Research to better understand Parkinson's disease and accelerate the development of new treatments. Our representatives will join the Partner Scientific Advisory Board closely involved in the design and execution of the study, as well as a variety of PPMI Working Groups. In February 2021, we announced a clinical trial collaboration and supply agreement with Merck KGaA, Darmstadt, Germany and Pfizer Inc. for Bavencio (avelumab), under which we intend to commence a clinical trial in the second half of 2021 to evaluate Bavencio in combination with MRx0518 as a first-line maintenance therapy for patients with locally advanced or metastatic urothelial carcinoma that has not progressed with first-line platinum-containing chemotherapy. In April 2021 we announced a sixth strategic collaboration, this time with Parkinson's UK to establish a patient advisory board to raise understanding of the treatment issues associated with neurodegenerative disease from a patient-centric perspective to help inform trial design. These partnerships are in addition to: an ongoing strategic collaboration with the University of Texas MD Anderson Cancer Center, to evaluate our Live Biotherapeutic oncology pipeline across a range of cancer settings; a clinical collaboration with MSD to evaluate MRx0518 in combination with Keytruda, an anti-PD-1 ICI marketed by MSD in patients with in patients with metastatic NSCLC, RCC and UC that are refractory to prior anti-PD-1/PD-L1 therapy; and a research collaboration and option to license agreement with MSD to discover and develop vaccines derived from our proprietary gut microbiome-derived commensal bacteria selected from our culture collection for use in up to three indications, combining our MicroRx platform with MSD's world-leading expertise in vaccine development.

4.   Intellectual property portfolio - Intellectual property is essential to our strategy and capturing the value of our world-leading research output. We have continued to invest significantly in expanding our IP rights, and by 30 June 2021 had initiated 68 patent families including over 1,000 granted patents providing coverage for our pipeline and clinical-stage candidates, manufacturing innovations and novel diagnostic approaches across major global markets. This is a 6.25% increase over the 64 patent families initiated as of 30 June 2020.

5.   Cash and equivalents - We continue to invest capital from our shareholders and partners into supporting research and clinical development programs, to generate the critical data to advance this novel modality. See the Liquidity and Capital Resources section below for additional information.

6.   Research and development spend - Investment in research and development (R&D) is central to our progress and returning long-term value. For the six months ended 30 June 2021 our R&D spend was £9.9 million compared to £12.4 million for the six months ended 30 June 2020. While maintaining our strategy to invest in our clinical development programs on a long term basis, the decrease is a reflection of both the action of management to reduce costs due to the effect of COVID and the change in clinical trial status due to the completion and relative reduction in associated costs of the Blautix trial in these comparable periods.

Components of operating results

Operating expenses

We recognize operating expenses as they are incurred in two general categories, general and administrative expenses and research and development expenses, and in a third more specific category for share-based payments. Our operating expenses also include non-cash components related to depreciation and amortization of property, plant and equipment and intangibles, which are allocated, as appropriate, to general and administrative expenses and research and development expenses.

General and administrative expenses consist of salaries and related expenses for executive, legal, finance and administrative personnel, as well as professional fees, insurance costs and other general corporate expenses. Management expects general and administrative expenses to increase in future periods as we add personnel and incur additional expenses related to an expansion of our research and development activities and our operation as a public company listed on two markets, including higher legal, accounting, insurance, compliance, compensation and other expenses.

Research and development expenses

Our research and development expenses consist primarily of salaries and related personnel expenses, contractual commitments, depreciation and amortization, patent costs and other expenses. We charge research and development expenses to operations as they are incurred. Costs are not directly tied to a specific product candidate until such product candidate enters the clinical trial stage. Product candidates often have more than one associated clinical trial related to different therapeutic areas or clinical indications. Once a product candidate enters a clinical trial, we track costs of such clinical trial but do not track other costs associated with specific clinical indications which are pooled.

The following table discloses the breakdown of research and development expenses:

We continue the robust progress of our proprietary development candidates into and through the clinic and to leverage the MicroRx® platform to generate value through partnerships, such as our research collaboration with MSD in the vaccines space. However, leading the way in the development of single strain Live Biotherapeutics does not come without investment, and we have sustained our commitment in the period to develop our clinical candidates, manufacturing processes and pipeline products, generating clinical data in multiple indications while launching new trials. Evidenced by our announcement to collaborate with Parkinson's UK to establish a Patient Advisory Board, we continued to progress promising new LBP candidates in exciting new areas like Parkinson's disease.

In February 2021, we announced a clinical trial collaboration and supply agreement with Merck KGaA, Darmstadt, Germany, and Pfizer Inc., under which 4D pharma intends to commence a clinical trial in the second half of 2021 to evaluate BAVENCIO® (avelumab) in combination with MRx0518 as a first-line maintenance therapy for patients with locally advanced or metastatic urothelial carcinoma that has not progressed with first-line platinum-containing chemotherapy.

After top-line data in the fourth quarter of 2020, the clinical phase of the Blautix® program completed in the six months to 30 June 2021 with additional positive data being presented during the period. Steady progress continued to be made during the period to 30 June 2021 with our three existing clinical trials of our therapeutic candidate, MRx0518, while the Phase I/II clinical trial of MRx-4DP0004 in partly controlled asthma saw us completing the enrolment of the 30 patients for Part A. However, our Phase II clinical trial of MRx-4DP0004 as an oral therapeutic to prevent or reduce the hyperinflammatory response in patients hospitalized with COVID-19 was closed due to the increase in vaccination rates and declining hospitalization rates. With the ongoing trials above, and as a result of the closure of the COVID-19 trial, but including the anticipated launch of a fourth trial in MRx0518 in 2021 in combination with BAVENCIO®, we anticipate that our research and development expenses for the second half of 2021 will result in lower research and development costs for the year than experienced in 2020.

With the Blautix® trial having produced its initial readout data in the latter stages of 2020, the six months ended 30 June2020 had higher clinical trial activity and costs than the six months ended 30 June 2021. In addition to this reduction, the expiration of minimum terms on certain manufacturing supplier contacts meant that certain expenses incurred were no longer contractual in nature and are now recorded under the manufacturing, research and development costs header. These decreases were partly offset by a modest increase in MRx0518 costs and an increase arising from recruitment on the Asthma trial, which had been delayed in 2020 due to recruitment issues resulting from COVID-19. Overall, these factors combined to see a reduction in contractual commitments from £6.2 million for the six months ended 30 June 2021 compared to £3.7 million for the six months ended 30 June 2020, a decrease of £2.5 million.

COVID-19 provided a point of inflection in 2020, with management taking swift action to scale back operations, cut costs or redirect resources, reducing baseline costs in certain areas; ultimately though, the impact was seen more towards the back end of the year ended December 31, 2020 and into 2021. Two of the main areas affected by the restructuring activities were the staff costs which decreased during the six months ended 30 June 2021 to £1.9 million from £2.5 million for the six months ended 30 June 2020. The MDx research costs also decreased £0.3 million between the same period due to limited scope of work on the project.

Other manufacturing, research and development costs increased to £1.2 million compared to £0.6 million for the six months ended 30 June 2021 and 2020, respectively. The increase was driven by two primary factors, the first of which related to the investment in manufacturing as we undertook exercises to improve commercial yields and to scale up our Parkinson's candidates for manufacture. Secondly, as noted earlier, certain minimum term contractual manufacturing related suppler contracts were still active during 2020 but the minimum term had been fulfilled come 2021, resulting in an increase of costs of £0.3 million for the six months ended 30 June 2021 as a result of their change in classification

Patent costs for the six months to 30 June 2021 have increased relative to the same period last year; this is in line with increases to the patent portfolio but also due to costs incurred defending certain patents.

Depreciation and amortization reduced in the period as certain assets reached the end of their estimated useful life without significant or necessary corresponding replacement costs being incurred.   

Results of operations

Details of the Group's results are included in the Group Statement of Total Comprehensive Income.

Revenues

We have not generated commercial revenues from product sales. To date, we have generated revenues from the collaboration agreement with MSD Collaboration Agreement. Our revenues from our MSD Collaboration Agreement totalled £0.2 million for the six months to 30 June 2021 and £0.3 million for the six months to 30 June 2020. There were no other revenues for the six months ended 30 June 2021 and 2020.

Research and development expenses

Our research and development expenses totalled £9.9 million for the six months ended 30 June 2021, representing a decrease of £2.5 million, or 20%, compared to £12.4 million for the period to 30 June 2020. The decrease was primarily attributable to the relative activity on the Blautix® Phase II trial, stemming from patient recruitment completing and top line data being released in October 2020, as a result of which the final data released in March 2021 had attracted lower overall costs in the six month period to 30 June 2021 when compared to the six months ended 30 June 2020. Details of other contributing factors are included above.

Administrative expenses

Our administrative expenses totalled £3.3 million for the six months to 30 June 2021, representing a £0.5 million reduction, or 13%, compared to £3.8 million for the six months ended 30 June 2020. Of the total, £0.8 million of the reduction expenditure related to legal fees which, at 30 June 2020, included transaction costs related to the fundraise in February 2020. Excluding these costs, there was an increase which was primarily attributable to the increase in insurance costs associated with the Nasdaq listing and increased patent costs, which were offset, in part, by reductions on staff costs and travel expenses as a result of COVID. General and administrative expenses are mainly attributed to staff costs, contractual commitments, legal and professional expenses and depreciation and amortization.

Foreign currency losses/(gains)

For foreign currency transactions included in the statement of operations and comprehensive loss, the exchange rates applicable to the relevant transaction dates are used. Transaction gains or losses arising from changes in the exchange rates used in the translation of such balances are carried to financing income or expenses. We recognized foreign currency gains of £0.2 million for the six months 30 June 2021, compared to foreign currency gains of £0.9 million for the half year to 30 June 2020. The change is due to the movement in exchange rates.

Other income

Other income consists of government grant income for a specific research project.

Operating loss before non-recurring items

As a result of the foregoing, our operating loss before non-recurring items totalled £12.7 million for the period to 30 June 2021 representing a decrease of £2.3 million when compared to £15.0 million for the period to 30 June 2020.

Non-recurring costs

Non-recurring costs relate to the costs associated with warrants and share options. The acquisition of Longevity Acquisition Corporation in March 2021 included several classes of warrants, options, and share based payment adjustments to the shares as part of the transaction, adding £44.2 million in fair value adjustments in the period to 30 June 2021. Comparably the six months to 30 June 2020 including £0.6 million relating to warrants issued as part of the February 2020 fundraise.

Operating loss after non-recurring items

As a result of the foregoing, our operating loss after non-recurring costs totalled £56.9 million for the period to 30 June 2021 representing an increase of £41.3 million when compared to £15.6 million for the period to 30 June 2020.

Finance income and expense

Finance income consists of interest earned on our short-term investments. Reductions in finance income over time have been attributable to poor interest rates. The reduction in finance expense costs relates to the repayment and subsequent reduction in underlying capital associated with the property financing arrangements.

Taxation

Taxation consists of UK and Irish research and development tax credits, deferred tax movements and US tax. Research and development tax credits are based on a proportion of our research and development expenditure and have reduced from £2.0 million for the six months ended 30 June 2020 to £1.5 million for the six months ended 30 June 2021. The decrease was due to the decrease in research and development expenses over the prior year.

Loss for the period

As a result of the foregoing, our net loss for the six months to 30 June 2021 was £55.5 million, representing an increase of £41.8 million over the £13.7 million for the six months to 30 June 2020.

Exchange differences on translating foreign operations

Exchange differences on translating foreign operations arose on consolidation with movements in exchange rates creating a loss of £0.7 million for the period to 30 June 2021 which represented a £0.9 million movement from the equivalent period in 2020 where a £0.2 million profit was reported. 

Loss for the period and total comprehensive income for the period

As a result of the foregoing, our net loss totalled £56.1 million for the period ended 30 June 2021, representing an increase of
£42.5 million over the £13.6 million for the period ended 30 June 2020.

Liquidity and capital resources

Overview

From our inception through to 30 June 2021, we have funded our operations principally from the sales of our ordinary shares, with some additional income from the MSD collaboration agreement and R&D tax credits. As of 30 June 2021, we had £20.7 million in cash and cash equivalents.

The table below presents our cash flows for the periods indicated:

Operating activities

Net cash used in operating activities of £11.5 million during the six months ended 30 June 2021 was primarily related to £3.8 million for clinical trials and research including other third-party expenses and an aggregate £2.5 million in salary and other staff costs; a further £2.2 million is attributable to patent spend with £3.0 million of legal, professional and insurance costs which are largely linked to the US listing. Foreign currency gains reduced expenditure in the period to 30 June 2021 by £0.2 million. Net cash used in operating activities of £13.9 million during the six months ended 30 June 2020 was primarily related to £7.9 million for clinical trials and research including other third-party expenses and an aggregate £3.3 million in salary expenses and other staff costs; a further £1.5 million is attributable to patent spend with £2.1 million of legal, professional and insurance costs which were largely related to fundraising activities. Foreign currency gains reduced expenditure in the period to 30 June 2020 by £0.9 million.

Investing activities

Net cash used in investing activities of £0.1 million and £0.2 million during the six months ended 30 June 2021 and 30 June 2020 respectively arose on the purchases of property, plant, equipment and software.

Financing activities 

Net cash provided by financing activities in the six months ended 30 June 2021 was £23.6 million. This represents the net proceeds from the issue of shares issued on the back of the acquisition of the Longevity Acquisition Corporation, the March 2021 placing and the Directors' fundraise which collectively contributed £23.8 million net of costs. Income from financing activities was reduced by £0.1 million on payment of lease and associated interest costs. Net cash used in financing activities in the six months ended 30 June 2020 of £20.3 million consisted of net income of £20.5 million from the issue of shares being offset by expenses of £0.2 million in lease payments.

In April 2021, following the release of the Annual Report for 2020, the directors who were unable to participate in the March 2021 financing, purchased 1.3 million Ordinary shares, on the same terms as the March 2021 financing; for a total of approximately £1.4 million ($2.0 million).  

In March 2021 we sold 16.4 million ordinary shares at £1.10 ($1.53) per share in a private placement generating £18.0 million ($25.0 million) in gross proceeds or £16.6 million ($23.0 million) net of transaction costs.

Also in March 2021 we completed the reverse recapitalization of Longevity Acquisition Corporation and subsequent listing on NASDAQ and received £10.7 million ($14.8 million) of cash and cash equivalents as well as payables and debts of Longevity of £2.4 million ($3.3 million) became available to the Company. Net proceeds, after transaction costs were approximately £5.6 million ($7.8 million). The purchase included the issue of 31.0 million ordinary shares and the Company assumed the existing Longevity public and private warrants, backstop warrants and representative units.

In July 2020, we completed the sale of 21.9 million ordinary shares at £0.35 per share for a total of approximately £7.1 million net of transaction costs.

In February 2020, we completed the sale of 44 million ordinary shares at £0.50 ($0.65) per share for a total of £22.0 million ($28.6 million) or £20.9 million ($27.0 million) net of transaction costs. One warrant was issued for share every two shares acquired for an exercise price of £1.00 ($1.30). The warrants are immediately exercisable and expire five years from issuance.

Current outlook

We have financed our operations to date primarily through proceeds from sales of our ordinary shares. We have incurred losses and generated negative cash flows from operations since inception. To date we have not generated significant revenue, and we do not expect to generate significant revenues from the sale of our product candidates in the near future. In order to capture the potential of the platform and maximize value creation, we are actively pursuing additional research collaborations, pairing our expertise in LBP discovery and development along with access to our library of well characterized bacterial isolates with the disease-specific expertise of partners.

In July 2021, we entered into a Loan Agreement with Oxford Finance providing for a term loan facility maturing on 1 July 2026 in an aggregate principal amount of up to $30.0 million. $12.5 million of such term loan was available and borrowed on the closing date. $7.5 million of such term loan is available upon the achievement of certain milestones. The remaining $10 million of such term loan is uncommitted and available at the discretion of the Lenders. The proceeds of the term loans may be used for general corporate purposes.

As of 30 June 2021, our cash and cash equivalent balance was £20.7 million. We expect that our existing cash and cash equivalents, including the cash received from the loan agreement in July 2021 will be sufficient to fund our operations through the fourth quarter of 2022. For further information, see the Subsequent Events note in the interim condensed consolidated financial statements included elsewhere in this report.

We currently anticipate that we will require approximately £23.2 million for research and development activities over the course of the next 18 months based on the execution of existing programs but also dependent on exchange rates. We also anticipate that we will require around £10.2 million for general and administrative costs over such 18-month period, which consists primarily of expenditures for staff costs, and legal, professional and insurance fees, and other administrative expenses. We also estimate approximately £6.1 million in cash for research and development tax credit refunds over this 18-month period.

Assuming all costs and income are as noted, and that there are no restrictions on the availability of cash, the Company anticipates that if cash and cash equivalent balances are available it can fund its activities until the fourth quarter of 2022. 

In addition, our operating plans may change as a result of many factors that may currently be unknown to us, and we may need to seek additional funds sooner than planned. Our future capital requirements will depend on many factors, including:

·      the length of the COVID-19 pandemic and its impact on our planned clinical trials, operations and financial condition;

·      the progress and costs of our pre-clinical studies, clinical trials and other research and development activities;

·      the scope, prioritization and number of our clinical trials and other research and development programs;

·      any cost that we may incur under in- and out-licensing arrangements relating to our product candidates that we may enter into in the future;

·      the costs and timing of obtaining regulatory approval for our product candidates;

·      the costs of filing, prosecuting, enforcing and defending patent claims and other intellectual property rights;

·      the costs of, and timing for, strengthening our manufacturing agreements for production of sufficient clinical and commercial quantities of our product candidates;

·      the potential costs of contracting with third parties to provide marketing and distribution services for us or for building such capacities internally;

·      the costs of acquiring or undertaking the development and commercialization efforts for additional future therapeutic applications of our product candidates and the magnitude of our general and administrative expenses; and

·      adverse trial results that would invalidate further investment in a product or products.

Principal commitments

Leased facilities

We have two real estate leases classified as right-of-use finance leases, one in Spain and one in the UK. No additional leases were entered into during the period. The UK lease is for our headquarters in Leeds. The premises comprise office space and parking and are for a 10-year term which commenced in May 2017. A tenant lease break clause is available in May 2022 which has not been included in the lease calculations as there is no indication that this would be executed. Lease escalation costs have been included on a fixed rate basis as a practical expedient. The lease includes a provision to return the premises to their original condition on exit; as such an asset retirement obligation of £0.3 million has been included in the valuation.

The Spanish lease relates to our manufacturing premises in Leon. The agreement is for a 10-year term which commenced in April 2016 and includes a tenant lease break clause that can be executed after providing six months' written notice at any point five years from the commencement date; again this break clause has not been included in the lease value as there is no evidence that this will be executed. Lease escalation costs have also been included on a fixed rate basis as a practical expedient. The lease includes the requirement to make certain repairs and as such an asset retirement obligation of £0.1 million has been included in the valuation.
