The MITOPE phase 1 multicenter study, (clinical trials.gov #NCT05278975) investigating the safety and tolerability of RSO-021, is a first-in-human trial. RSO-021 is a first-in-class therapy for treatment of mesothelioma and solid tumors in patients with malignant pleural effusion. Professor Dean Fennell from Leicester Hospitals Trust in the UK will present the complete dose escalation data as part of a rapid oral session and answer questions during a moderated panel discussion.

Aggressive cancers present tremendous challenges in treatment and management, primarily due to rapid growth and spread to other parts of the body. Malignant pleural effusion (MPE) develops as a direct extension of cancer into the pleural space and is associated with shorter life expectancies. Currently, the phase 2 expansion portion of MITOPE is underway in the UK, exploring RSO-021 as both a single agent and in combination therapy to treat stage IV metastatic cancers with MPE, including mesothelioma, lung, breast and ovarian cancers. Other causes of MPE include cancer that has spread from the stomach, kidney, ovaries, and colon. Dr. Sean Dulloo from University of Leicester will present an update of the MITOPE Phase 2 trial as a trial-in-progress poster presentation.

The data is embargoed until published by ASCO (Free ASCO Whitepaper) 5:00 PM (EDT) on Thursday, May 23, 2024.
