• Icovamenib Achieves a Mean Reduction in HbA1c Greater than 1% at Week 26 Following 4 Weeks of Dosing in Type 2 Diabetes Patients Characterized by Insulin Deficiency
• 32 patients from the 100mg and 200mg cohorts, doses selected for the expansion phase, were characterized based on baseline biomarkers and analyzed for efficacy. Patients identified as insulin deficient (approx. 50% of the broader patient population) and insulin resistant were compared to examine the mean reduction in HbA1c at Week 26, following 4 weeks of dosing.
• 83% of patients with insulin deficiency responded to icovamenib, and showed a greater mean HbA1c reduction at Week 26 compared to baseline, than those that were found to be more insulin resistant (-1.23% vs -0.48%, placebo-adjusted, 22 weeks after last dose of icovamenib).
• These two patient groups are pre-specified in the upcoming read out of the Phase IIb expansion portion of COVALENT-111 in December, reporting over 200 persons with type 2 diabetes (T2D) with 8 and 12 weeks of icovamenib treatment.

Data Highlights for Presentations at ATTD-Asia 2024

T2D is characterized by a progressive decline in beta-cell function while type 1 diabetes (T1D) is characterized by autoimmune destruction of beta cells leading to hyperglycemia. Preclinical data suggests investigational icovamenib may induce beta-cell proliferation and improve insulin secretion. In the multiple ascending dose portion of the Phase II COVALENT-111 trial, many T2D participants achieved clinically significant improvements in glycemic control up to 22 weeks after only 4 weeks of daily icovamenib. At ATTD-Asia the company will report the Phase II expansion design of COVALENT-111 (NCT05731544) evaluating icovamenib in adults with T2D and the Phase II design of COVALENT-112 (NCT06152042) evaluating icovamenib's efficacy and safety in adults with T1D.

T2D is a heterogenous disease, characterized by varying degrees of insulin resistance and insulin deficiency. Covalently inhibiting menin is a new proposed mechanism of action particularly relevant for diabetes patients with a depleted pool of beta cells. The severe insulin-deficient diabetes (SIDD) and mild age-related diabetes (MARD) subgroups, two of five identified by Ahlqvist et al., encompass approximately 50%-70% of patients with T2D¹, depending on the population, and are distinguished by significant insulin deficiency.

The company will present a review of insulin-deficient versus insulin-resistant patients based on T2D participants in the escalation portion of COVALENT-111, representative of exposure expected in the expansion portion. Here, after only 4 weeks of dosing and with a follow up 22 weeks after the last dose, the insulin-deficient diabetes patients (SIDD and MARD subgroups), showed a mean 1.23% placebo adjusted decline in HbA1c while the patients characterized by insulin resistance (severe insulin-resistant diabetes and mild obesity-related diabetes subgroups) demonstrated a mean 0.48% placebo adjusted decline. Subtyping diabetes patients may help identify specific subgroups for improved targeted treatment approaches in the future.

Two case studies from the escalation portion of COVALENT-111 are also being presented to highlight the potential of icovamenib in patients with poorly controlled insulin-deficient T2D. One of the patients, a 29-year-old man with a four-year history of T2D, experienced a 2.5% reduction in HbA1c (from 9.5% at baseline to 7.0%) at Week 26, dropping an additional 1.2% at Week 47 (down to 5.8%) leading to the discontinuation of metformin. Both HOMA-B (+190.0%) and C-peptide (+71.0%) increased significantly during the 26-week study period. The other insulin deficient patient, a 45-year-old man with a 10-year history of T2D, had a 1.1% reduction in HbA1c from baseline (8.6% to 7.5%) at Week 26 with increases in HOMA B (+1233.0%) and C-peptide (+59.0%). In both cases icovamenib was generally well tolerated, there were no adverse events, no dose discontinuations or modifications reported, and no symptomatic or clinically significant hypoglycemia was observed.

In addition, the company is hosting an industry symposium entitled “Unlocking the Potential of Menin Inhibition: Icovamenib and a Look into the Future of Diabetes Management,” chaired by Professor Juliana Chan and Dr. Juan Pablo Frías, to discuss beta-cell biology and introduce the novel therapeutic approach for diabetes through menin inhibition. Key topics discussed include the fundamentals of beta-cell biology and its critical role in glucose homeostasis; the pivotal role of menin in pancreatic beta-cell function and diabetes pathogenesis, and an overview of the COVALENT-111 (T2D) and COVALENT-112 (T1D) clinical studies. A focal point of the symposium will be an in-depth presentation on T2D subgroups, highlighting their distinct characteristics and phenotypes to enhance the understanding of T2D heterogeneity and its implications for personalized treatment strategies.

Upcoming COVALENT-111 Study Read-Out

The Phase IIb expansion portion of COVALENT-111 is designed to further explore icovamenib’s potential for long-term glycemic control, dosing patients for up to 12 weeks at various dosing levels with follow-up at Week 26 and 52. The study aims to identify the optimal dose for late-stage development and define biomarkers for patients who respond best to icovamenib alone. Key inclusion criteria are persons with T2D with a HbA1c greater than 7.0%, a BMI of 25 to 40, who have had diabetes onset within the last seven years and were failing their current treatments, which could include up to three anti-diabetic medications, including GLP-1 based therapies. We believe the study is designed to help understand the impact of dosing the broader patient population and determine icovamenib’s potential impact on insulin-deficient and insulin-resistant patients. The goal is to select the optimal dose, dose duration, and patient set to advance to late-stage clinical development. Inhibiting menin in patients with diabetes is a novel and investigative treatment modality, and the study will help define a study population to discuss with the Food and Drug Administration during a potential end of Phase II meeting in 2025.

"We’re pleased to present our case studies at ATTD-Asia and show the overall benefit we believe icovamenib may provide, particularly to insulin-deficient patients with T2D. We expect the upcoming topline results in December will provide critical insights into how icovamenib affects both insulin-deficient and insulin-resistant patients and help us identify the biomarkers for optimal patient selection. I am very excited about icovamenib’s potential and look forward to reporting our study results," stated Juan Pablo Frias, MD, Biomea Fusion’s Chief Medical Officer.

About COVALENT-111

COVALENT-111 is a multi-site, randomized, double-blind, placebo-controlled Phase I/II study. In the completed Phase I portion of the trial, healthy patients were enrolled in single ascending dose cohorts to evaluate safety at the prospective dosing levels for T2D patients. Phase II consists of multiple ascending dose cohorts and includes adult patients with T2D uncontrolled by standard of care medicines. Once the escalation portion of COVALENT-111 was completed, the study advanced into an expansion portion consisting of multiple cohorts dosing T2D patients up to 12 weeks with either icovamenib or placebo, followed by a 40-week off treatment period. To date, approximately 200 patients completed their respective dosing. Additional information about this Phase I/II clinical trial of icovamenib in T2D can be found at ClinicalTrials.gov using the identifier NCT05731544.

About COVALENT-112

COVALENT-112 is a multi-site, randomized, double-blind, placebo-controlled Phase II study in adults with stage three T1D. This stage describes the period following clinical diagnosis of T1D when symptoms are present due to significant beta cell loss. COVALENT-112 includes an open-label portion for adults with T1D up to 15 years since diagnosis. The open-label portion (n=40) examines the efficacy, safety, and durability of icovamenib at two oral dose levels, 100 mg and 200 mg over a 12-week treatment period followed by a 40-week off treatment period. To date, approximately 20 patients completed 8 weeks of dosing in the open label portion. Additional information about the Phase II clinical trial of icovamenib in T1D can be found at ClinicalTrials.gov using the identifier NCT06152042.
