Ali Mortazavi, Chief Executive Officer of e-therapeutics, commented: "I am extremely pleased with the progress the Company has made in the period. In particular, with further milestone achievements in our partnership with Galapagos and the completion of a successful equity fund raise. The raise enables enhanced investment for the Company to accelerate the development of RNAi therapeutics and to further develop our computational capabilities. Since the fund raise, we have made excellent progress in all areas of the Company and we are building on this positive momentum.

"We are delighted to announce top-line positive results from in vivo studies in non-human primates, confirming the Company's proprietary GaINAc-siRNA platform has been successfully benchmarked against leading competitor RNAi platforms. These excellent results show that our proprietary delivery system and siRNA chemistries are competitive relative to peer platforms. This is a material step in the Company's ultimate goal of developing an in-house RNAi pipeline with future scope for early-stage partnering. Eleven new patent applications have been filed to protect these innovations. In parallel, we are developing the world's largest data resource in hepatocyte biology which will enable the identification and prosecution of novel therapeutic targets, both internally and with collaborators.

"We believe that e-therapeutics offers a differentiated strategy, with the ability to silence any gene in the liver with extremely rapid pre-clinical timelines, coupled with powerful computational capabilities, including in hepatocyte biology. We look forward to the future with great excitement."

About e-therapeutics plc

e-therapeutics plc is an Oxford, UK-based company integrating computational power and biology to accelerate the discovery of life-transforming medicines. The Company has developed and validated a powerful, disease and modality agnostic computational approach to drug discovery, leveraging its industry-leading expertise in network biology to fully capture and interrogate human disease complexity. 

The Company's multi-disciplinary team builds computational models of biological functions to transform the search for new medicines, interventions, mechanisms and genetic support. Its biology-led in silico laboratory enables rapid hypothesis generation and phenotypic screening of millions of compounds leading to 100-1000x higher hit rates in the wet lab and successful mode of action elucidation. Novel targets can also be identified, prioritised and assessed. Harnessing internal target gene discoveries, e-therapeutics is currently building an in-house pipeline of RNAi based medicines, using its proprietary GalNAc-siRNA technology. 

e-therapeutics has deployed and validated its disease-agnostic computational drug discovery platform both in house and with partners, including Novo Nordisk, Galapagos NV and a US-based, top 5 pharmaceutical company.

Chief Executive's Statement

I am pleased to report a strong and productive six months for the Company where we have successfully achieved numerous milestones. e-therapeutics' ambition is to successfully integrate computational power and biology to discover life-transforming medicines and enable all diseases to be treated. For this to happen, we believe that the traditional drug discovery process needs to be transformed and we are in a position to significantly contribute to, and be leaders in, this transformation.

RNAi liver platform

A key component of our strategy was to establish a therapeutic technology platform which is reproducible and would give us the ability to design potential drug candidates as quickly as possible. This would put us in a position of being able to rapidly prosecute novel target genes identified using our computational engine.

Our modality of choice is RNAi. GalNAc (N-Acetylgalactosamine)-conjugated siRNA is a powerful and well validated commercial-stage technology, which enables specific delivery to hepatocytes in the liver, patient-friendly subcutaneous administration and a long duration of therapeutic action. There is a high barrier to entry in GalNAc-siRNA as it is a highly sophisticated and advanced therapeutic modality, with unique advantages. As reflected in today's separate announcement, which includes headline data on our proprietary RNAi platform, we now have the ability to inhibit any of the c.10,000 genes expressed in hepatocytes (liver cells) and design candidates in 3-6 months and at a cost of c.$500,000. By way of comparison, the average time and cost of discovering a small molecule drug is over 4 years and with a cost of c.$4 million.

A further example of the speed and cost of so called "information molecules" (drug agents which are based on genetic sequences) is the remarkable timelines of mRNA (messenger RNA) COVID-19 vaccines. By way of our own example, in February 2021, we designed 24 of these GalNAc-siRNA information molecules against 3 gene targets in the liver. By October 2021, we successfully tested these molecules in cell-based assays, rodents and non-human primates. The capability of a platform such as GalNAc-siRNA, with remarkable specificity (both in terms of delivery and target gene inhibition) and the above timelines will be a critical competitive advantage to test the outputs from our computational biology platform.

Target identification is currently the biggest limitation in GalNAc-siRNA and there is a high degree of overlap in competitive pipelines. An important differentiator for the Company relative to RNAi peers is the ability to leverage its computational platform to identify better, novel therapeutic targets. Our computational platform is also an enabler in the discovery of mechanistic insights, assessment of genetic support and in silico evaluation of target hypothesis ahead of wet lab experiments.

Computational drug discovery

To complement our GalNAc-siRNA capabilities and feed our in-house pipeline, the Company has created a hepatocyte-focused specialisation within its core computational platform. e-therapeutics is also executing on an ambitious data strategy to create the most comprehensive and integrated hepatocyte-centric data resource in the world, tailored to our computational biology approach to drug discovery. We are compiling experimental data at genome-wide scale using bespoke human hepatocyte assays and combining it with our existing state-of-the-art network analytics and artificial intelligence/machine learning ("AI/ML") approaches to create a seamless connection between the computer and the laboratory. Our assays are guided by our in silico work and our in vitro experimental data feed back into making better and better models of biology. In addition, the Company is building the most complete hepatocyte KG, integrating its experimental data and its newly created AI/ML enhanced, hepatocyte protein-protein interactome. The KG already includes data derived from natural language processing of hundreds of thousands of documents and data sources, patient-derived information, patent mining and human expertise.

The Company's KG is structured in such a way as to allow it to perform ML-driven mechanistic inference to impute missing links and uncover hidden knowledge. This integrated resource will provide the Company with an unprecedented foundation from which to derive disease intervention hypotheses, support network model construction, carry out target identification, support target validation and discover genetic support for targets. It will also provide data and insights to feed into its AI-driven siRNA design workflows, which are another addition to our tool kit. The foundations for this data strategy are already in place and providing insights as we continue to grow and enhance our capabilities. Furthermore, the KG and tailored computational tools we have developed in hepatocytes can be replicated in additional cell types of interest.

Importantly, the Company has expanded its network-aware target identification, MoA (mode of action) elucidation and target deconvolution capabilities. This has been possible via the augmentation of network-based analysis with a suite of proprietary AI/ML approaches.

The enhanced applications of the Company's computational platform that have been achieved to date will be a key enabler both internally and for partners and will complement the Company's phenotypic focused approaches. In addition, e-therapeutics continues to streamline its computational platform via increased automation and cloud computing.

Partnerships and Collaborations

During the period, the Company made further progress on its collaboration with Galapagos to identify new therapeutic approaches to modulate a specific mechanism involved in IPF and potentially in other fibrotic indications with high unmet need.

The Company met three key pre-defined milestones in the period, receiving three payments from Galapagos. e-therapeutics successfully identified hit compounds for Galapagos, which were experimentally validated. In keeping with previous validation of the Company's computational platform, experimental testing of compounds predicted by e-therapeutics in several relevant assays, yielded a hit rate several orders of magnitude higher than industry standards. The collaboration is on track and these hits are currently being characterised further, including target deconvolution (identification of targets). Under the terms of the agreement, the Company is eligible to receive additional milestone payments through pre-clinical and clinical development as well as commercial milestones.

Additional discussions are in progress with other biopharma companies in diverse therapeutic areas including CNS disorders, oncology and rare disease.

Additional patent applications

Post period in October 2021, the Company announced it had filed five new patent applications relating to its innovative GalNAc-conjugated siRNA construct designs, including around stabilising chemical modifications enabling specific hepatocyte (liver cell) targeting. A further six new patent applications have now also been filed. 

These patent applications will protect the Company's inventions in GalNAc-siRNA and its position in the field. Further filings are anticipated as we continue to make progress.

Outlook

We expect to continue progressing our GalNAc-RNAi platform and to populate our in-house liver centric RNAi pipeline, spanning both complex disease (e.g. cardiovascular, metabolic) and systems biology approaches to mono- and oligogenic diseases. Based on recent progress, we also anticipate offering our RNAi platform to potential business development partners over the coming months.

The Company continues to look to maximise the value of its computational biology platform, both applying all its functionality to its RNAi platform, from novel target identification to siRNA sequence design and beyond, as well as through collaborations around network biology approaches to drug discovery outside RNAi.

We look forward to presenting further details on the GalNAc-siRNA and computational platforms and our strategy as part of an R&D Day in 2022. The Company is firmly of the belief that e-therapeutics will be at the forefront in the emerging field of Pharmatech.

Financial Review

Period end cash of £31.6m and an operating loss of £3.5m in H1 2022.

In the first half of the financial year, the Company has continued to carefully manage the underlying cash burn whilst focusing on generating income and achieving external commercial validation with our partners as well as investing in a new RNAi platform. In addition, we completed a significant fund raise of £22.5 million gross in June 2021.

Revenue

The Company's on-going collaboration with Galapagos continued to progress resulting in recognition of £0.5 million of revenue, a significant increase on the prior year (H1 2020: £0.04 million), driven primarily by receipt of payments associated with milestones.

Research & development

The research and development expenditure in H1 2021 increased to £2.5 million (H1 2020: £1.2m). The increase reflects a doubling in salaries in line with the enlarged scientific headcount and the significant additional investment, both in-house and outsourced, in our computational and RNAi platforms.

We are expecting the R&D in H2 2022 to continue to increase significantly as we accelerate investment in our RNAi platform. We intend to progress further with scaling the existing platform capabilities in H2 2022.

General & Administrative expenses

Administrative expenses in the first half of the financial year of £1.5m were in line with the same period in the prior year (H1 2020: £1.5m).

Loss for the period

The Net Loss for the period was £2.8m (H1 2020: £2.4m).

Cash flow

Cash as at 31 July 2021 stood at £31.6m, an increase of £18.6m when compared to the start of the current financial year (cash as at 31 January 2021: £13.0m). The net income from the fundraise accounts for £21.6m and we received R&D tax credits in relation to the prior year of £780k, leaving an underlying net cash outflow of £3.8m attributable to the operating loss, cash receipts from the Galapagos collaboration and working capital movements.

Financial outlook

Our current expectations for underlying cash burn in the second half of the current financial year will be higher than that incurred in H1 as we further progress our R&D activities and build administrative infrastructure capable of supporting the scaling of the business.
