On September 13, 2024 Nxera Pharma and Cancer Research UK reported an upcoming presentation on the ongoing Phase 1/2a clinical trial (NCT05944237) of Nxera’s immunotherapy drug HTL0039732 (also known as NXE0039732) at the European Society for Medical Oncology Congress (ESMO) (Free ESMO Whitepaper) 2024, taking place on 13–17 September in Barcelona, Spain (Press release, Nxera Pharma, SEP 13, 2024, View Source [SID1234646620]).

The trial’s co-chief investigator, Dr. Debashis Sarker from Guy’s and St Thomas’ NHS Foundation Trust, will present a "Trial in Progress 1 " poster at ESMO (Free ESMO Whitepaper) 2024 on Saturday 14 September (presentation 679TiP, available on the ESMO (Free ESMO Whitepaper) website here).
The first-in-human trial is evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and anti-tumor activity of HTL0039732 as a monotherapy and in combination with the checkpoint inhibitor atezolizumab, in patients with advanced solid tumors.
HTL0039732 is an oral small molecule drug candidate that was rationally designed using Nxera’s NxWave platform and evaluated through rigorous translational and preclinical studies. HTL0039732 works by blocking signaling through a specific type of prostaglandin receptor, the prostaglandin E2 (PGE2)-type prostanoid receptor 4 (EP4). PGE2 acts in the tumor microenvironment to trigger cancer cells to evade the immune system. Targeting EP4 to block the effects of PGE2 increases the ability of the immune system to detect and control cancer cells and makes HTL0039732 a potential candidate to treat patients with cancers that generally do not respond well to current immunotherapies.
Cancer Research UK’s Centre for Drug Development is sponsoring and managing the trial, which is led by chief investigator Dr Bristi Basu, University of Cambridge, and Dr Sarker. The first patient was dosed in August 2023 and the trial is currently open for recruitment at Addenbrooke’s Hospital in Cambridge, Guy’s Hospital in London, and the Christie Hospital in Manchester
Dr. Debashis Sarker says: "We are excited to present this ‘Trials in Progress’ poster at ESMO (Free ESMO Whitepaper), outlining the
scientific rationale and design of the clinical trial of HTL0039732, given alone and in combination with immunotherapy for patients with advanced solid cancers. HTL0039732 targets an important protein within the tumor immune microenvironment called EP4, triggering cancer cells to evade the immune system. Targeting EP4 potentially increases the ability of the immune system to detect and control cancer cells. Enrolment to the trial began in the UK in August 2023 and is ongoing across multiple cancer types.
"We are hopeful that this trial will identify a novel way to target the immune system and improve treatment
options for patients with a range of different solid cancers."
