AUSTIN, Texas, March 28, 2019 (GLOBE NEWSWIRE) -- Molecular Templates, Inc., (Nasdaq: MTEM) a clinical stage biopharmaceutical company focused on the discovery and development of Engineered Toxin Bodies (ETBs), a new class of targeted biologic therapies that possess unique mechanisms of action in oncology, today announced the initiation of a single-agent Phase II study of MT-3724, a CD20-targeted ETB, in relapsed/refractory diffuse large B-cell lymphoma (DLBCL) patients. This multicenter study will enroll up to 100 patients, in a staged manner, who have received at least two standard of care treatment regimens for DLBCL. As a monotherapy study in heavily pretreated patients, this study has the potential to be pivotal.
“We have been highly encouraged by the responses observed in the Phase I/Ib study of MT-3724 in heavily pretreated DLBCL patients,” said Eric Poma, Ph.D., CEO and CSO of Molecular Templates. “This Phase II study largely replicates the Phase Ib expansion cohort, but with more clinical sites for enrollment, an independent data safety monitoring board, and independent central review for efficacy. Given the high level of unmet need in advanced DLBCL, we hope that this study will confirm that MT-3724 provides a meaningful benefit for this difficult to treat patient population.”
The Phase II study will initially enroll patients at sites in the United States, Canada and Europe. MT-3724 will be given as 50 mcg/kg intravenous (IV) infusions, with a maximal per dose limit of 6,000 mcg. The primary outcome measure is tumor response, while secondary objectives include safety and other efficacy measures. The Phase II dose of 50 mcg/kg was selected based on safety data, tumor responses observed at dose levels as low as 5 and 20 mcg/kg, and pharmacodynamic effects of CD20+ B-cell clearance observed at various doses in the Phase I/Ib study. The Phase II study will exclude patients with high levels of serum rituximab, given CD20 binding competition of rituximab with MT-3724.
About Molecular Templates
Molecular Templates is a clinical-stage oncology company focused on the discovery and development of differentiated, targeted, biologic therapeutics for cancer. We believe our proprietary biologic drug platform technology, referred to as engineered toxin bodies, or ETBs, provides a differentiated mechanism of action that may address some of the limitations associated with currently available cancer therapeutics. ETBs utilize a genetically engineered form of Shiga-like Toxin A subunit, or SLTA, a ribosome inactivating bacterial protein, that can be targeted to specifically destroy cancer cells.
