Evaluate the modulation of WNK1 (lysine deficient protein kinase 1) and other related pathways induced by the Company’s rose bengal, and
Complete demonstration of STING (stimulator of interferon genes) dimerization in leukemia cells.
The Narendran team has previously shown:

In vitro activity and target modulation effects of Provectus’ rose bengal against several different pediatric leukemia‐derived cell lines and primary cells,
Proof‐of-concept of several potential mechanisms that may be involved in this process,
Rose bengal’s ability to induce STING dimerization and the molecule’s association with heat shock proteins, and

As of June 30, 2022, NuCana had cash and cash equivalents of £46.5 million compared to £52.6 million as of March 31, 2022 and £60.3 million at December 31, 2021. NuCana continues to advance its various clinical programs and reported a net loss of £3.9 million for the quarter ended June 30, 2022, as compared to a net loss of £9.1 million for the quarter ended June 30, 2021. Basic and diluted loss per share was £0.07 for the quarter ended June 30, 2022, as compared to £0.17 per share for the quarter ended June 30, 2021.

"During the first half of the year, we have remained focused on the rapid and efficient implementation of our development plans," said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. "In the past few months, we initiated two studies: NuTide:323, a randomized Phase 2 trial of NUC-3373 in combination with other agents for the treatment of second-line patients with colorectal cancer; and NuTide:303, a Phase 1b/2 study of NUC-3373 in combination with other agents including the PD-1 inhibitor pembrolizumab, for the treatment of patients with solid tumors. We also continue to enroll patients in the Phase 1b/2 NuTide:302 study of NUC-3373 in patients with colorectal cancer and the Phase 2 monotherapy part of the NuTide:701 study of NUC-7738 in patients with solid tumors, which will expand to include combination with pembrolizumab."

Mr. Griffith continued: "From a corporate perspective, we recently announced that the Regional Court of Dusseldorf issued a judgement that Gilead’s sofosbuvir infringes our European composition-of-matter patent. We will continue to defend our patent rights and the foundational work of our late Chief Scientific Officer, Professor Chris McGuigan. Additionally, we regained compliance with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market."

Mr. Griffith concluded: "We have provided multiple data updates for both NUC-3373 and NUC-7738 that demonstrate the potential of our ProTides to offer more effective and safer treatment options for patients with cancer. These data have highlighted the compelling anti-cancer activity and favorable safety profiles and pharmacokinetic properties of our product candidates. With an anticipated cash runway into 2025 and through numerous key milestones for both NUC-3373 and NUC-7738, we remain on track to provide a number of data updates over the coming year as we continue to advance our pipeline."

Anticipated Milestones: H2 2022 and H1 2023

"In the first half of 2022, we delivered on major new and existing collaborations, advanced our pipeline programmes, and marked the 10-year anniversary of Exscientia’s founding. Over the past decade, we’ve pioneered an AI-driven approach to modernising drug discovery and development, and it was fitting that this quarter we also announced topline data from our EXS-21546 programme, one of the first AI-designed molecules to enter clinical trials," said Andrew Hopkins, D.Phil., Exscientia’s founder and Chief Executive Officer. "With over $730 million in cash, we believe we are in a strong position to deliver across our portfolio of drug projects for the long-term. Our strategy creates an agile interplay between our internal pipeline and partnered programmes, enabling us to move candidates between the two depending on the best fit for Exscientia and our partners, as well as how we can best impact the probability of success for patients."

Recent Highlights

Progress across internal and partnered pipeline, leveraging the Company’s precision medicine platform, as well as key components of Exscientia’s technology and operations.

Internal pipeline

Wholly, majority and co-owned programmes focused on areas in which Exscientia believes it can improve the probability of success, including precision oncology

Following topline data in June, the Company remains on track to initiate a Phase 1b/2 study of EXS-21546 (majority owned with Evotec) in the second half of 2022
Phase 1b/2 study will be optimised with simulation-guided clinical trial design principles as well as leverage Exscientia’s precision medicine platform to maximise potential impact to the most relevant patients

Utilising a scalable end-to-end platform to advance a broad pipeline, while also generating significant cash inflows to support advancements

First two targets identified in new Sanofi collaboration for oncology and inflammation & immunity, respectively
First precision medicine project initiated; focused on patient enrichment for a Sanofi biologic in oncology
Advancing Bristol Myers Squibb (BMS) collaboration with continued progress across both BMS1 and BMS2 collaborations
Following the achievement of recent successful drug discovery milestone, Exscientia and Bayer have mutually agreed to end collaboration; Exscientia will retain optionality to develop one of the two targets pursued under the collaboration
The Bayer agreement was the last Exscientia partnership based on AI-only design services, which included lower economics and reduced operational involvement in comparison with more recent partnerships
This update aligns with Company strategy to increasingly focus on programmes where Exscientia’s AI design, experimental biology and precision medicine platforms can be integrated
Recent clinical progress highlights ability of the Company’s advanced, AI-based platform to create novel molecules with high level of translatability to human biology

Announced topline data from EXS-21546 Phase 1a healthy volunteer study in June 2022
