For more information visit us at www.c4xdiscovery.com or follow us on twitter @C4XDiscovery.

Corporate Overview

We have continued to make strong progress across the entire portfolio, both during the period and into the beginning of 2023.  Our most significant news was announced in November with the out-licensing of our NRF2 Activator programme to AstraZeneca for up to $402 million, including $2 million upfront, and up to $16 million in potential pre-clinical milestone payments, plus the potential for tiered single-digit royalties. 

Our portfolio of partnered programmes continues to advance. Indivior's Phase I multiple-ascending dose clinical trial of C4XD's Orexin 1 Antagonist candidate C4X_3256/INDV-2000 is underway and, following the first milestone received from Sanofi, our IL-17A Inhibitor programme is advancing through pre-clinical studies towards the next milestone.  We look forward to hearing how these programmes progress throughout the year.

Following a review of our expertise and previous successes, C4XD is evolving its strategy to become a company focused on treatments for immuno-inflammatory diseases.  With the majority of our portfolio already focused on immuno-inflammatory diseases, a proven drug discovery expertise and an expert team of scientists who understand this disease area, we believe that with this approach we can harness our skillset and take the development of our programmes further, providing greater value for shareholders.

Our internal portfolio will now focus on the discovery and development of novel small molecule medicines with Best-in-Class and First-in-Class potential to treat patients across a range of immuno-inflammatory diseases.  Our lead internal programme, focused on oral small molecule inhibitors of α4β7, has the potential to expand patient access to α4β7 inhibitor therapy for the treatment of inflammatory bowel disease ("IBD").  This programme is making significant headway through late-stage discovery and progressing towards pre-clinical studies.  We have further immuno-inflammatory programmes in early discovery and we anticipate moving the two most promising of these into Lead Optimisation within the next 18 months.

In line with our new focus on immuno-inflammatory diseases, the decision has been taken to streamline our portfolio and prioritise resources, and we therefore plan to out-license our pre-clinical MALT-1 inhibitor programme for oncology.

In January 2023, we were delighted to appoint Nick Ray as our Chief Scientific Officer.  Nick has been with C4XD for seven years, most recently as SVP Drug Discovery and also leading the medicinal chemistry, structural analysis and computational chemistry/cheminformatics teams.  He has played a key role in the growth of C4XD and his in-depth scientific expertise has enabled C4XD to develop a growing portfolio of high-quality small molecule programmes.  Nick's leadership will be invaluable as we look to take these programmes further into development.

In February 2023, following a successful research collaboration with Garvan Institute, we announced the launch of C4XD's new platform for patient stratification, PatientSeek (powered by Taxonomy3®) - see study details in the Portfolio Review.  The results of the study demonstrate PatientSeek's ability to optimise patient selection and its potential to match the most effective treatments with groups of patients who are most likely to benefit thereby ensuring the right drug is given to the right patient, based on their genetics.  C4XD has already identified subgroups in a number of immuno-inflammatory diseases using PatientSeek and we will be exploring their application in bringing precision medicine approaches to these patient populations.

The Company has a sufficient cash position and manageable fixed cost base. Cash, cash equivalents, short-term investments and deposits were £9.6 million at 31 January 2023 (31 January 2022: £11.7 million).  R&D investment of £5.2 million in the six months ending 31 January 2023 (January 2022: £3.9 million), reflecting focused investment in key Drug Discovery programmes.  Administrative Expenses remained steady at £1.6 million for the six months ended January 2023 (January 2022: £1.6 million).

Portfolio Review

Addictive disorders (Orexin-1 Antagonist) - out-licensed to Indivior

Phase 1 multiple ascending dose study ongoing

Under C4XD's milestone and royalties agreement with Indivior worth up to US$284 million for C4XD's oral Orexin-1 receptor antagonist C4X_3256 (INDV-2000) for the treatment of substance use disorders, Indivior has completed the Single Ascending Dose (SAD) Phase 1 study with no events of clinical concern. The Multiple ascending dose (MAD) study is progressing with Last Subject Last Visit (LSLV) scheduled for July 2023, and with other clinical, non-clinical and chemical/formulation development activities proceeding to plan.

Opioid addiction is an increasing burden on the healthcare system, particularly in the US but is a growing global issue.  According to the U.S. Center for Disease Control & Prevention (CDC), more than 107,937 people are predicted to have died from drug overdose, up 56% in the 12-month period ending August 2022, with 73,369 of these deaths attributed to synthetic opioids, up 115%¹.

Inflammation (IL-17A Inhibitor) - out-licensed to Sanofi

Sanofi-led programme making significant progress

Under the exclusive worldwide licensing agreement worth up to €414 million, Sanofi continues to make strong pre-clinical progress towards the second milestone; C4XD received the first milestone payment of €3 million in July 2022.  The small molecules in C4XD's oral IL-17A inhibitor programme can selectively block IL-17 activity whilst maintaining molecular size of the molecule in the traditional "drug-like" range.  A novel, potent oral series of IL-17A inhibitors that significantly reduce IL-17 induced inflammation in vivo is being optimised.  Sanofi has development and commercial rights to the programme and is continuing to work with C4XD in the next discovery phase, utilising our Conformetrix technology, interpretation and application to compound design as the programme progresses towards the clinic.

Inflammation (NRF2 Activator) - out-licensed to AstraZeneca

Programme continues to move forward under AstraZeneca's ownership

C4XD signed an exclusive worldwide licensing agreement with AstraZeneca in November 2022, worth up to $402 million, for its NRF2 Activator programme.  AstraZeneca will develop and commercialise an oral therapy for the treatment of inflammatory and respiratory diseases with a lead focus on chronic obstructive pulmonary disease (COPD).  Under the terms of the agreement, C4XD will receive pre-clinical milestone payments worth up to $16 million including $2 million upfront, ahead of the first clinical trial.  In addition, C4XD will receive a further potential $385.8 million in clinical development and commercial milestones and tiered mid-single digit royalties upon commercialisation.

Inflammation is a key driver in many pathological conditions.  NRF2 plays a pivotal role in controlling the expression of antioxidant genes that ultimately exert anti-inflammatory functions.  Targeting the NRF2 pathway to reduce inflammatory damage offers the potential for a new approach to treat a variety of inflammatory diseases.  Interest in this therapeutic approach covers multiple therapeutic areas including chronic obstructive pulmonary disease, atopic dermatitis, IBD, pulmonary arterial hypertension and sickle cell disease. 

Inflammation (α4β7 Integrin Inhibitor)

Programme transitioned into Lead Optimisation

C4XD's oral α4β7 integrin inhibitor programme has identified multiple series of novel, potent and selective α4β7 integrin inhibitors for the treatment of IBD.  Effective antibody therapy against this target is already approved, removing the clinical target risk, but an effective oral therapy remains highly sought after.  During 2021, Morphic Therapeutic's Phase 1 clinical study demonstrated high target occupancy in blood at developable doses but with a twice daily profile.  C4XD's programme is targeting a much desired once-a-day profile.

Oral bioavailability has been demonstrated and there is particular focus on improving PK properties to achieve a good oral half-life. C4XD has compounds that match or exceed both whole blood potency and selectivity values when compared to examples from current clinical patent estates, with correspondingly improved activity at a lower dose when profiled in a T-cell gut-homing pharmacodynamic model.

Haematological Cancer (MALT1 Inhibitor)

Moving towards identification of pre-clinical candidate shortlist

MALT1 is one of the key regulators of B-cell receptor (BCR) and T-cell receptor (TCR) signalling. Mutations that lead to constitutive activation of MALT1 are associated with aggressive forms of non-Hodgkin B-cell lymphoma and inhibition of MALT1 has potential therapeutic applicability as a mono therapy for MALT1-driven cancers such as activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL) and in combination with BTK and Bcl inhibitors across multiple haematological indications, as well as broader potential in solid tumours and inflammation.

Our Conformetrix technology has yielded multiple structurally distinct series, two of which have progressed into Lead Optimisation. Profiling of a Lead compound in a mouse xenograft study has shown equivalent efficacy at equivalent dose to the Johnson & Johnson clinical compound JnJ-67856633 (in Phase 1) and the programme is moving forward to identification of candidate shortlist molecules. C4XD has initiated partnering discussions for this programme.

Expansion of Pipeline

As we look to scale our portfolio, early-phase programmes targeting a number of targets across a range of immuno-inflammatory diseases are being resourced to identify those with the highest potential to warrant increased spend and prosecution to and through Lead Optimisation and eventually into the clinic.  These programmes target clear unmet medical need, combined with significant commercial potential and a unique opportunity to produce valuable chemical equity  through interpretation of conformational insight via C4XD's Conformetrix technology.  Additionally, we are using our PatientSeek platform (vide infra) to inform our target selection choices, based on identification of patient stratification opportunities and improved trial design. Details of each programme will be provided once they have matured to Lead Optimisation stage.

PatientSeek

C4XD has launched a precision medicine platform, PatientSeek, based on its Taxonomy3® technology, following insights from a successful research collaboration with Garvan Institute of Medical Research. In the collaboration, C4XD provided Garvan Institute with the genetic signatures for its PatientSeek sub-groups in Parkinson's disease. Garvan researchers then applied this as part of a retrospective analysis of a failed Phase 3 Parkinson's clinical trial that had not reached its primary endpoint, to assess if a genetic subgroup of participants showed a benefit from the therapeutic. Very encouragingly, PatientSeek identified a subgroup that responded to the trial drug. These results provide the first validation of PatientSeek's ability to identify patient subgroups to optimise patient selection, which in turn could lead to enhanced probability of targeted success in clinical trials.  The results from this study will be submitted for publication in a peer reviewed journal.  Whilst this study was focused on Parkinson's disease, the PatientSeek platform is disease agnostic and can be applied to any complex genetic disease and we will look to expand and explore the immuno-inflammatory diseases subgroups for application in our own portfolio.

Outlook

C4XD has continued to make huge strides across our portfolio during the period, including our third global out-licensing deal, this time with AstraZeneca for our NRF2 Activator programme worth up to $402 million.  This brings our deal value to a total of $1.2 billion with large pharmaceutical companies, further validating our reputation for generating high-quality small molecules.  Following a review of our expertise and previous successes, C4XD is evolving its strategy to become a company focused on treatments for immuno-inflammatory diseases.  With our proven expertise in drug discovery and our rigorous approach to programme development, we believe that a more focused approach on immuno-inflammatory diseases will allow us to harness our skillset and take the development of our programmes further, providing greater value for shareholders.

3.   Revenue

Revenue in the current period has been generated from contracts with two customers.

In the current period a new contract was signed with a new customer which has been determined to have three performance obligations - the transfer of intellectual property which has been recognised as right-to-use licence revenue at a single point in time; the provision of consultancy and technical support which will be recognised over time in line with the level of consultancy provided; and the facility of on-going research which will be reimbursed on a pass-through cost basis.

The revenue attributed to the delivery of research services was generated from one customer and is recognised over time. The progress is measured based on costs incurred to date as compared with the total projected costs for both the current and prior periods.

Revenue In the prior periods was generated from a contract with a single customer. In the prior period, the milestone revenue was determined to have one performance obligation and was recognised at a point in time. The revenue attributed to the delivery of research services was recognised on the same basis as in the current period.

4.   Taxation

5.   Loss per share

The number of exercisable share options and warrants above are those deemed to be potentially dilutive in nature as their exercise price is less than the average share price for the period. As the group made a loss in the current and comparative period the effects of these potential ordinary shares are not dilutive.
