Brief Summary:
Phase 2 Trial of BMF-219 in Participants with Type 1 Diabetes Mellitus.

Condition or disease Intervention/treatment Phase
Type 1 Diabetes Mellitus Drug: BMF-219 Phase 2

Detailed Description:
Study COVALENT-112 is a 52-week, Phase 2 trial designed to examine beta-cell function, insulin sensitivity, and both glucose and lipid metabolism in participants with T1D treated with BMF-219. BMF-219 is an orally bioavailable, covalent small-molecule menin inhibitor.

Arm Intervention/treatment
Experimental: Part 1

Part 1 uses a randomized, open-label design with parallel assignment between 2 treatment arms in each cohort. The Part 1 Eligible participants will be randomly assigned by cohort to 1 of 2 treatment arms:

  • Cohort 1: Participants with T1D diagnosed within 3 years with C-peptide concentration ≥0.2 nmol/L
  • Arm A: BMF-219 100 mg QD for 12 weeks
  • Arm B: BMF-219 200 mg QD for 12 weeks
  • Cohort 2: Participants with T1D diagnosed between 3 to 15 years with C-peptide concentration ≥0.08 nmol/L.
  • Arm A: BMF-219 100 mg QD for 12 weeks
  • Arm B: BMF-219 200 mg QD for 12 weeks
 Drug: BMF-219
BMF-219 is an orally bioavailable, covalent small-molecule menin inhibitor.
Experimental: Part 2

Part 2

Part 2 uses a randomized, double-blind, placebo-controlled design with parallel assignment among 3 treatment arms. Eligible participants will be randomly assigned to 1 of 3 arms using a 1:1:1 ratio:

  • Arm A: BMF-219 100 mg QD for 12 weeks
  • Arm B: BMF-219 200 mg QD for 12 weeks
 Drug: BMF-219
BMF-219 is an orally bioavailable, covalent small-molecule menin inhibitor.
Placebo Comparator: Placebo Comparator
Part 2 Study Double Blind Arm C matching placebo for 12 weeks.
 Drug: BMF-219
BMF-219 is an orally bioavailable, covalent small-molecule menin inhibitor.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. To assess the effect on endogenous insulin secretion [ Time Frame: 26 Weeks ]
    Mean change from baseline in stimulated C-peptide AUC.


Secondary Outcome Measures :
  1. To assess the effect on endogenous insulin secretion [ Time Frame: 26 Weeks ]
    Maximum stimulated C-peptide: the highest value at any time point during the 4-hour MMTT.

  2. To assess the effect on additional glycemic parameters [ Time Frame: 26 Weeks of treatment ]
    Mean change from baseline in HbA1c.

  3. To assess the effect on additional glycemic parameters [ Time Frame: 26 Weeks ]
    Mean change from baseline in FPG.

  4. To assess hypoglycemia events [ Time Frame: 26 weeks ]
    Percentage of participants with hypoglycemic episodes (with confirmed self-plasma glucose monitoring) including level 2 hypoglycemic events (<54 mg/dL regardless of symptoms) and level 3 (severe) hypoglycemia across different timepoints.

  5. To assess the effect on insulin doses [ Time Frame: 26 Weeks ]
    Change from baseline in mean daily insulin dosing.

  6. Rate of symptomatic hypoglycemic episodes [ Time Frame: 26 Weeks and during study duration ]
    Evaluation and comparison of the number of symptomatic (both minor and severe) hypoglycemic episodes with BMF-219 vs placebo during the study.

  7. Incidence of adverse events [ Time Frame: 26 Weeks and during study duration ]
    Evaluation and comparison of the number of adverse events with BMF-219 vs placebo during the study.
