Brief Summary:
This is a Phase 1, open-label, multicenter, multiple dose, dose escalation study of the safety, PK, PD, and anti-tumor activity of IDE397 as a single agent in adult patients with selected advanced or metastatic MTAP-deleted advanced solid tumors who are unresponsive to standard of care therapy or for whom no curative therapy is available.

Condition or disease Intervention/treatment Phase
Solid Tumor Drug: IDE397 Phase 1

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: N/A
Intervention Model: Sequential Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label, Phase 1, Treatment Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics of IDE397 (MAT2A Inhibitor) In Adult Participants With Advanced Solid Tumors
Actual Study Start Date : April 14, 2021
Estimated Primary Completion Date : December 31, 2022
Estimated Study Completion Date : December 31, 2024

Arm Intervention/treatment
Experimental: Dose Escalation Monotherapy
IDE397 dosed orally, once daily (QD) for each 21-day cycle
Drug: IDE397
Small molecule inhibitor of methionine adenosyltransferase 2 alpha (MAT2A)

Primary Outcome Measures :
  1. Dose-limiting Toxicities (DLTs) of IDE397 [ Time Frame: 21 days following the first dose of IDE397 ]
    Incidence of DLTs of IDE397 will be determined

  2. Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of IDE397 [ Time Frame: Approximately 2 years ]
    MTD and RP2D of IDE397 will be determined

Secondary Outcome Measures :
  1. Plasma Pharmacokinetics of IDE397 and metabolite [ Time Frame: Approximately 2 years ]
    Pharmacokinetics of IDE397 and metabolite following single and multiple oral administration will be determined

  2. Preliminary anti-tumor activity [ Time Frame: Approximately 2 years ]
    Objective response rate and duration of response will be assessed using the Response Evaluation Criteria in Solid Tumors (RECIST v1.1)

  3. Pharmacodynamic effect of IDE397 [ Time Frame: Approximately 2 years ]
    Changes in the levels of MAT2A pathway (SAM and MAT2A) and PRMT5 pathway (SDMA) will be determined
