AUSTIN, Texas, Aug. 11, 2022 (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), to create novel therapies with potent and differentiated mechanisms of action for cancer and other serious diseases, today reported financial results and business updates for the second quarter of 2022.

“We are pleased with the progress we are making to advance our potent ETB pipeline of drug candidates which are highly differentiated from Antibody-Drug Conjugates (ADCs), each with a substantial and unique value proposition,” said Eric Poma, PhD., Chief Executive and Chief Scientific Officer of Molecular Templates. “We presented six posters on our programs at the 2022 American Association for Cancer Research (AACR) Annual Meeting, as well as two posters on MT-6402 (PD-L1 ETB with Antigen Seeding Technology) and MT-5111 at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, and we look forward to reporting updates in the second half of the year as we plan to expand our Phase 1 study of MT-6402 in PD-L1+ patients and continue dose-finding in the MT-5111 and MT-0169 programs. We remain on track toward our anticipated IND submission for MT-8421 (CTLA-4 ETB with unique I/O approach) and are executing on additional novel ETB programs targeting TROP2, TIGIT, and BCMA. We also continue to move forward with our collaboration agreement with Bristol Myers Squibb.”

ETB Technology

ETBs represent a novel platform for therapeutic development with unique biology. In contrast to Antibody Drug Conjugates (ADCs), ETBs leverage differentiated biology and MoAs which include internalizing or non-internalizing targets, endosomal escape with self-routing to cytosol, enzymatic ribosome inactivation, and cytosolic/ER delivery. ETBs can also alter the immunophenotype of tumor cells through Antigen Seeding technology. MTEM is developing ETBs against validated targets where its differentiated biology may allow for efficacy in a relapsed/refractory setting.

Immuno-Oncology ETBs:

MT-6402 and MT-8421 represent MTEM’s unique approach to immuno-oncology based on dismantling the TME through direct cell-kill of immune cells rather than blocking of ligand-ligand interactions as seen with current antibody therapeutics.

MT-6402 (PD-L1 ETB with Antigen Seeding Technology)

• MT-6402 is a 3rd generation ETB designed to induce potent anti-tumor activity via PD-L1 targeting  with unique effects that include  the dismantling of the tumor microenvironment by directly destroying PD-L1+ immune cells, direct cell-kill of PD-L1+ tumor cells, and immunophenotype alteration of PD-L1+ tumor cells in HLA-A*02 /CMV+ patients.
• The Phase 1 study of MT-6402 began in July 2021. It is 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 (TME) are eligible for enrollment.
• As of August 5, 2022,  16 patients with relapsed/refractory tumors that express PD-L1 have been treated to date across three dose cohorts: 16 mcg/kg (n=6), 24 mcg/kg (n=6) and 32 mcg/kg (n=4). Dosing continues with two patients currently enrolled in cohort 4 at 42 mcg/kg.
• At the 24 mcg/kg dose, there was a grade 2 dermatitis that resolved rapidly with oral steroids. The patient reported mild pruritus and was rechallenged without incident at the same dose. No other DLTs have been reported. Cohort 3 (32 mcg/kg) was completed with no DLTs. Cohort 4 (42 mcg/kg) has been initiated.  
• One patient in  Cohort 1 (16 mcg/kg) with non-small cell lung cancer (NSCLC) demonstrated tumor regression. This patient was one of two patients with high tumor PD-L1 expression and was also HLA-A*02/ CMV+. Another patient with modest PD-L1 expression of 10% Tumor Proportion Score has remained on treatment with stable disease for greater than nine months. 
• Following determination of the maximum tolerated dose (MTD), MTEM will plan expansion cohorts to evaluate MT-6402, both as a monotherapy and as a combination approach with a PD-1 inhibitor in tumor-specific and PD-L1 positive basket tumor cohorts.
• MTEM continues to observe pharmacodynamic (PD) effects not seen with PD-L1 antibodies and consistent with the dismantling of the TME including PD-L1+ immune cell depletion and T cell activation, as well as cytokine changes in TNF-α, IL-2, and vascular endothelial growth factor (VEGF) in all dose escalation cohorts evaluated to date. The extent and timing of these PD effects appear dose-related with patients in the 24 and 32 mcg/kg cohorts generally showing a more rapid and profound PD effect, including monocyte depletion and T cell activation, potentially in a dose-dependent manner.
• PD effects associated with immune activation were seen across the majority of patients irrespective of HLA genotype or level of tumor or immune cell PD-L1 staining. The patient who demonstrated tumor regression was one of two patients treated with high tumor PD-L1 expression and may represent engagement of direct tumor cell-kill and antigen seeding.

MT-8421 (CTLA-4 ETB)

• Preclinical data from MTEM’s CTLA-4 program were featured in a poster at the AACR annual meeting held April 8-13, 2022. In a transgenic mouse model expressing human CTLA-4 and bearing syngeneic subcutaneous tumors, MT-8421 treatment depleted immune suppressive regulatory T cells (Tregs) in the TME.
• MT-8421 was well tolerated in a non-human primate toxicology study and achieved serum levels well-above projected IC₅₀ concentrations for Tregs in the TME.
• An IND filing for MT-8421 is expected year-end 2022, with clinical studies expected to commence in the second quarter of 2023.
• The ETB approach includes potent destruction of CTLA-4+ Tregs via enzymatic ribosome destruction, and the mechanism of cell kill is independent of the TME. There is also preferential activity on high CTLA-4 expressing Tregs in the TME.

Research

• MTEM continues to expand its unique approach to immuno-oncology targets with lead optimization ongoing for a TIGIT-targeting ETB and additional exploration around new immuno-oncology targets. TIGIT ETB candidates deplete TIGIT+ immune cells ex vivo and in vivo. Sub-nM potency on TIGIT+ cell lines and reversal of Treg mediated suppression of T-cell proliferation have been seen along with depletion of Tregs in murine TME.

Targeted Solid Tumor ETBs:

MT-5111 (HER2 ETB)

• The Phase 1 study of MT-5111 in HER2-positive cancers is ongoing with multiple sites open for enrollment.
• The HER2-positive breast cancer expansion cohort was initiated in November 2021 at a dose of 10 mcg/kg.
• As of June 2022, 35 patients have been treated with MT-5111 across nine dose escalation cohorts ranging from 0.5 mcg/kg to 17 mcg/kg without any DLTs, including two patients who were treated for six months or longer.
• Enrollment in the 23 mcg/kg cohort has been initiated.
• Six patients have been treated with breast cancer on the expansion cohort at 10 mcg/kg; three patients have remained on treatment for greater than 28, 16, and 10 weeks, respectively, with stable disease.
• One patient with gastric cancer experienced a grade 3 rash at a dose of 23 mcg/kg.  The rash subsided to grade 1 with topical steroids and the patient continues to be treated at the same dose.  Dose escalation will continue to determine the MTD while the breast cancer expansion cohort collects efficacy and safety data.
• To date, no cases of clinically significant cardiotoxicity have been observed in human subjects who have been dosed with MT-5111. 
• Serum concentration of MT-5111 showed predictable and dose-proportional increasing exposure in the last four evaluable dose cohorts.
• Higher MT-5111 doses (6.75 mcg/kg and above) appear to saturate circulating soluble HER2 (sHER2) receptors with patients’ sHER2 levels stabilizing or decreasing at higher doses.

Research

• Lead optimization on a 3^rd generation ETB targeting TROP-2 continues.
  

Hematologic Malignancy Targeted ETBs:

MT-0169 (CD38 ETB)

• The revised protocol for the ongoing Phase 1 study in patients with relapsed/refractory multiple myeloma (MM) or non-Hodgkin’s lymphoma is now open. One patient with MM has started treatment at 5 mcg/kg. The revised protocol explores a lower dose of MT-0169 to reduce the risk of adverse events observed at the initial dose of 50 mcg/kg and to enable patients to continue MT-0169 therapy for a longer duration that may drive tumor benefit. The robust and rapid NK cell depletion that was observed at the starting dose of 50 mcg/kg is expected to be observed at lower doses, based upon IC₅₀ in vitro data.
• MTEM is opening new sites for the Phase 1 study and enrollment resumed in July 2022.

Research

• Lead optimization on BCMA continues.
