Molecular Templates Presents Interim Data from MT-6402 Phase I Study in Patients with PD-L1+ Solid Tumors at the 2024 American Association for Cancer Research (AACR) Annual Meeting; Monotherapy Activity in Checkpoint-Experienced Head and Neck Cancer Patients Observed Through Novel Immuno-oncology Mechanism
(GlobeNewswire)
- P1 | N=138 | NCT04795713 | Sponsor: Molecular Templates, Inc. | "MT-6402 has been well tolerated with no drug-related Grade 4 or Grade 5 adverse events observed. MT-6402 acts uniquely from other approved checkpoint agents. MT-6402 depletes immunosuppressive PD-L1+ immune cells and tumor cells, activates a T-effector phenotype, and remodels the tumor microenvironment to restore T-cell surveillance of the tumor....An early monotherapy efficacy signal in head and neck squamous cell carcinoma (HNSCC) was identified. Nine patients with recurrent and metastatic heavily pre-treated and checkpoint-experienced HNSCC were treated in the phase I dose escalation of which two patients have confirmed durable PRs....Tumor reductions were observed in other patients including an unconfirmed PR."

(GlobeNewswire)
- P1 | N=138 | NCT04795713 | Sponsor: Molecular Templates, Inc. | "Molecular Templates, Inc...today provided an update on its programs...The Part A dose escalation of the phase I study for MT-6402 has been completed with no Grade 4 or Grade 5 drug-related adverse events observed to date...In the Part A dose escalation, 10 patients with head and neck squamous cell cancer (HNSCC) were treated at doses of 63, 83, or 100 mcg/kg. Two of these patients were not evaluable for the cycle 1 dose-limiting toxicity ('DLT') period or for efficacy because of early progression and came off study after receiving only one or two doses of MT-6402, respectively...The three other HNSCC patients enrolled in the Part A dose escalation had stable disease of 6, 4, and 2 months, respectively....The Part B dose expansion portion of the phase I study in patients with high PD-L1 is ongoing."

Engineered Toxin Bodies (ETBs): Clinical stage immunotoxins with a safer and differentiated profile
(AACR 2023)
- "Three ETBs (MT-0169, MT-5111, and MT-6402) are currently in clinical studies across different targets (CD38, HER2, PD-L1) and across hematologic malignancies, solid tumor, and immuno-oncology indications. ETBs can also deliver additional payloads to drive unique biology like the alteration of tumor immunophenotype. Here we describe three active clinical stage programs with encouraging safety and efficacy data that represent a transformation of the immunotoxin landscape into a more viable therapeutic approach to target validated as well as typically intractable clinical cancer targets."

Engineered toxin bodies specific for TROP2 positive cancers
(SABCS 2022)
- "Three ETBs are in clinical development (MT-5111 targeting HER2, MT-0169 targeting CD38, and AST enabled MT-6402 targeting PD-L1)...TROP2 is a clinically validated target in metastatic triple-negative breast cancer (mTNBC) and other cancers such as metastatic urothelial carcinoma (mUC) using antibody drug conjugate (ADC) therapies such as sacituzumab govitecan (Trodelvy®)...In vivo, TROP2 targeted ETBs demonstrate good tolerability in a murine HCC1806 triple-negative breast cancer xenograft model and significantly reduce tumor burden relative to vehicle control. These pre-clinical in vitro and in vivo data suggest AST enabled Trop2 targeted ETBs have the potential to deplete Trop2 positive malignancies through multiple unique mechanisms of action."

(GlobeNewswire)

The extent and timing of these PD effects appear dose-related with patients in the 24 mcg/kg cohort generally showing a more rapid and profound PD effect....Higher MT-5111 doses (6.75 mcg/kg and above) appear to saturate circulating soluble HER2 (sHER2) receptors with patients’ HER2 levels stabilizing or decreasing at higher doses."

Engineered toxin bodies (ETBs) targeting Trop2
(AACR 2022)
- "This MOA allows for the intracellular processing of antigen and subsequent surface MHC-I presentation required for activation of a re-directed T lymphocyte response and the capacity to restore a functional immune clearance program against the tumor.Three ETBs are in clinical development (MT-5111 targeting HER2, MT-0169 targeting CD38, and AST enabled MT-6402 targeting PD-L1). AST enabled Trop2 targeted ETBs are capable of delivering viral antigens for multiple HLA types and inducing cytokine secretion and T-cell mediated killing in a co-culture assay of Trop2 target cells with antigen matched HLA type and antigen specific T-cells. These pre-clinical in vitro data suggest AST enabled Trop2 targeted ETBs have the potential to deplete Trop2 positive malignancies through multiple unique mechanisms of action."
