Molecular Templates, Inc. Reports Fourth Quarter 2020 Financial Results

AUSTIN, Texas, March 18, 2021 (GLOBE NEWSWIRE) — Molecular Templates, Inc. (Nasdaq: MTEM, “Molecular Templates,” or “MTEM”), a clinical-stage biopharmaceutical company focused on the discovery and development of proprietary targeted biologic therapeutics, engineered toxin bodies (ETBs), today reported financial results for the fourth quarter of 2020.

“In 2020 and early 2021, we made important progress by advancing our pipeline programs, establishing a new collaboration with a premier oncology partner, and strengthening our balance sheet with a successful equity financing,” said Eric Poma, Ph.D., Molecular Templates’ Chief Executive and Scientific Officer. “We now have four clinical stage programs: MT-5111 targeting HER2, TAK-169 targeting CD38 in co-development with Takeda, MT-6402 with antigen seeding targeting PD-L1, and MT-3724, for which we are working to resolve the FDA partial clinical hold. We expect to generate clinical data from multiple programs and advance our earlier stage programs in 2021, including filing an IND for an ETB targeting CTLA-4, preclinical data presentations on ETBs against new targets, and continued progress in our collaborations with Bristol Myers Squibb, Vertex, and Takeda.”

Company Highlights and Upcoming Milestones

Corporate

• On February 11, 2021, MTEM and Bristol Myers Squibb announced a strategic research collaboration to discover and develop multiple novel therapies designed for specific oncology targets. Under the collaboration, MTEM will conduct research activities for the discovery of next generation ETBs for multiple targets, of which the first target has been selected by Bristol Myers Squibb. Bristol Myers Squibb made an up-front payment of $70 million to MTEM and MTEM is also eligible to receive near-term and development, regulatory and sales milestone payments of up to approximately $1.3 billion as well as tiered royalty payments on future sales.
• On February 18, 2021, MTEM announced the pricing of an underwritten public equity offering, the gross proceeds of which were approximately $75.9 million.
• MTEM has had three abstracts accepted for presentation at the upcoming American Association for Cancer Research (AACR) Annual Meeting 2021, taking place virtually from April 10-15, 2021:
  • MT-5111 (interim Phase 1 data as of December 2020), abstract CT130, titled “Phase 1 study of the novel immunotoxin MT-5111 in patients with HER-2+tumors.”
  • MT-6402 (preclinical data), abstract 1628, titled “Engineered toxin bodies targeting PD-L1 to alter tumor immunophenotypes and deliver broad antigenic diversity and patient coverage.”
  • CTLA-4 ETB (preclinical data), abstract 1627, titled “Preclinical characterization of a novel CTLA-4-targeted ETB for direct Treg depletion.”

MT-5111 (HER2 ETB)

• The Phase 1 study of MT-5111 in HER2-positive cancers is ongoing with multiple sites open for enrollment.
• In December 2020, MTEM provided an update on the ongoing Phase 1 study. No dose limiting toxicities were observed in any cohort and no signs of cardiotoxicity have been observed to date, while monitoring the subjects’ EKGs, troponin values and pro-BNP with each treatment, and serial echocardiograms with every other cycle. No cases of capillary leak syndrome, or CLS, (any grade) were observed.
• The HER2-positive breast cancer expansion cohort is planned to begin in 1H21 at a dose of 10 mcg/kg (anticipated to be a therapeutic dose level), pending adequate safety data. Dose escalation will continue to determine the recommended Phase 2 dose while the breast cancer expansion cohort collects efficacy and safety data.
• MTEM expects to present interim clinical results from the dose escalation portion of the MT-5111 Phase 1 study as of December 2020, at the AACR Annual Meeting April 10-15, 2021. MTEM expects to provide an update on additional data from both the dose escalation portion of the study and the metastatic breast cancer dose expansion cohort in 4Q21.

TAK-169 (CD38 ETB)

• Takeda and MTEM are currently conducting a Phase 1 study for TAK-169 in relapsed/refractory multiple myeloma. This study, which started dosing in February 2020, had a temporary pause in the activation of new study sites and new patient enrollment (along with most of Takeda’s other early-stage studies) due to COVID-19 and was re-initiated in 4Q20.
• In December 2020, preclinical TAK-169 data were presented at the 62nd ASH Annual Meeting and Exposition.

MT-6402 (PD-L1 ETB with antigen seeding)

• On January 19, 2021, MTEM announced that the U.S. Food and Drug Administration (FDA) accepted its Investigational New Drug (IND) application for MT-6402.
• MTEM expects to start dosing in a first-in-human Phase 1 study in relapsed/refractory patients with PD-L1-positive solid tumors in 2Q21. The Phase 1 study is planned as a multi-center, open-label, dose escalation and dose expansion trial. Patients with confirmed PD-L1 expressing tumors or confirmed PD-L1 expression in the tumor microenvironment will be eligible to screen for enrollment in the clinical trial. Following determination of the maximum tolerated dose (MTD) or recommended Phase 2 dose, expansion cohorts are planned to study MT-6402 as a monotherapy in tumor-specific and tumor-agnostic cohorts.

MT-3724 (CD20 ETB)

• Since November 4, 2020, all MT-3724 clinical studies have been on partial clinical hold as ordered by the FDA following a treatment-related fatality in one subject who experienced Grade 5 CLS in the Phase 2 MT-3724 monotherapy study. As part of the overall investigation into the partial clinical hold on MT-3724, MTEM investigated MT-3724 product quality attributes. Based on the findings, MTEM submitted a partial clinical hold response to the FDA in February 2021 in which it proposed to implement new drug product manufacturing and release specifications.
• MTEM is working to address the partial clinical hold and MT-3724 product lot information requests from the FDA.
• In tandem, MTEM is actively evaluating the role of MT-3724 and CD20 as a target in MTEM’s portfolio relative to other opportunities.

Research

• MTEM expects to file an IND application for an ETB targeting CTLA-4 in 4Q21.
• Several other ETB candidates are in preclinical development against targets including SLAMF-7 and CD45.
• In 2021, MTEM expects to present preclinical data on new targets and new ETBs at medical and scientific conferences.
