Mesothelioma clinical trials at UCSF

TC-510 is a novel cell therapy that consists of autologous genetically engineered T cells expressing two synthetic constructs: first, a single-domain antibody that recognizes human Mesothelin, fused to the CD3-epsilon subunit which, upon expression, is incorporated into the endogenous T cell receptor (TCR) complex and second, a PD-1:CD28 switch receptor, which is expressed on the surface of the T cell, independently from the TCR. The PD-1:CD28 switch receptor comprises the PD-1 extracellular domain fused to the CD28 intracellular domain via a transmembrane domain. Thus, the switch is designed to produce a costimulatory signal upon engagement with PD-L1 on cancer cells.

This study will evaluate intrapleural administration of Adenovirus-Delivered Interferon Alpha-2b (rAd-IFN) in combination with Celecoxib and Gemcitabine in patients with histologically confirmed Malignant Pleural Mesothelioma (MPM) who have failed a minimum of 1 treatment regimen and a maximum of 2 treatment regimens, 1 of which must have been an anti-folate and platinum combination regimen. Eligible patients will be randomized 1:1 to either: 1. Treatment group: rAd-IFN + Celecoxib followed by Gemcitabine 2. Control group: Celecoxib followed by Gemcitabine Patients randomized to the treatment group will receive rAd-IFN administered into the pleural space via an Intrapleural catheter (IPC) or similar intrapleural device on study Day 1. The primary objective of this study is to compare the overall survival (OS) associated with rAd IFN, when administered with celecoxib and gemcitabine, versus that associated with celecoxib and gemcitabine alone for the treatment of patients with MPM

Gavocabtagene autoleucel (gavo-cel; TC-210) is a novel cell therapy that consists of autologous genetically engineered T cells expressing a single-domain antibody that recognizes human Mesothelin, fused to the CD3-epsilon subunit which, upon expression, is incorporated into the endogenous T cell receptor (TCR) complex. This Phase 1/2 study aims to establish the recommended Phase 2 dose (RP2D) and subsequently evaluate the efficacy of gavo-cel, with and without immuno-oncology agents, in patients with advanced mesothelin-expressing cancers, with overall response rate and disease control rate as the primary Phase 2 endpoints.

This is a Phase 2b, randomized, double-blind, parallel-group study. Subjects with unresectable pleural or peritoneal malignant mesothelioma will be randomized in a 2:1 ratio to receive either tremelimumab or placebo. Approximately 564 subjects will be enrolled at study centers in multiple countries. The study consists of a screening period, a treatment period, a 90-day follow-up period for safety, and a long-term survival follow-up period.
