Navlimetostat for MTAP-deleted solid tumors: monotherapy and combination therapy

Official title: A Phase 2 Open-Label, Multi-Center Study of Navlimetostat (BMS-986504) as Monotherapy and in Combination With Other Agents in Participants With Advanced and/or Metastatic Solid Tumors With Homozygous MTAP Deletion (MountainTap-5)

Run by Bristol-Myers Squibb · NCT07492680 · Data updated 2026-11-12

This study tests Navlimetostat alone and with other cancer drugs in people with advanced solid tumors that lack MTAP, to see if it is safe and if it can help shrink tumors.

Is this trial a fit for you?

Likely a good fit

Adults with advanced/metastatic solid tumors that harbor homozygous MTAP deletion or MTAP loss in tumor tissue, who have measurable disease and acceptable organ function.

Probably not a fit

Patients whose tumors do not respond to MTAP-targeted strategies or who have tumor biology not driven by MTAP loss may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, open-label Phase 2 trial evaluating Navlimetostat (BMS-986504) in patients with MTAP-deleted advanced or metastatic solid tumors. It includes a monotherapy dose-expansion portion and a combination-dose escalation portion with partner anticancer agents. The study will assess safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity both alone and in combination. Additional cohorts may be opened as data emerges to explore other regimens. Overall, the trial aims to identify feasible dosing and potential signals of benefit in this genetic subset.

Why it matters

Potential benefit: If successful, participants may experience tumor control or slowed progression and gain access to a targeted therapy tailored to MTAP loss.

How similar studies have gone: Prior MTAP-targeted approaches have shown signals of activity in select MTAP-deleted tumors, but this specific Navlimetostat program is still in early phases.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Participant must have histologically confirmed diagnosis of advanced and/or metastatic solid tumor malignancy with homozygous deletion of the MTAP gene or MTAP loss detected in tumor tissue.
* Depending on the cohort enrolled, participants must have received standard therapies appropriate for their tumor type and stage with disease progression on or after the most recent treatment (there must be no available treatment with curative intent or participant is ineligible or declines treatment) or be treatment-naïve with no prior systemic anticancer therapy for their unresectable or metastatic disease.
* Participant must have presence of at least one measurable tumor lesion per RECIST v1.1 or mRECIST at baseline and Radiologic assessment in neuro-oncology (RANO)2.0 as applicable at baseline.
* Coagulation function: International normalized ratio (INR) and activated partial thromboplastin time (APTT) must be ≤ 1.5 × ULN; or ≤ 2 x ULN in subjects with liver metastasis or liver cancer.
* Participant must have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Exclusion Criteria:

* Participants must not have prior treatment with a PRMT5 or Methionine adenosyl transferase 2A (MAT2A) inhibitor.
* Participants must not have active brain metastases or carcinomatous meningitis. Participants are eligible if brain metastases are adequately treated, and participants are neurologically stable for at least 2 weeks prior to enrollment without the use of corticosteroids or are on a stable or decreasing dose of ≤ 10 mg daily prednisone (or equivalent).
* Participants must not have history of gastrointestinal disease or other gastrointestinal conditions within 6 months prior to enrollment (including uncontrolled nausea, vomiting, malabsorption syndrome or non-gastrointestinal fistula, gastrointestinal perforation, or intra-abdominal abscess) likely to alter absorption of study treatment or result in inability to swallow oral medications.
* Participants must not have inadequate organ function, as determined by laboratory testing within the screening period.
* Participants must not have active viral HBV or HCV hepatitis.
* Other protocol defined inclusion/exclusion criteria applies.
