About this study

Official title: A Phase 1/2, First in Human, Dose Escalation and Dose Expansion Study of BHV-1510 (Previously PBI-410) as Monotherapy and in Combination With Anti-Cancer Agents in Participants With Advanced Solid Tumors

This is a Phase 1/2, first in human (FIH), open-label, multicenter study of BHV-1510 monotherapy and in Combination with Cemiplimab in participants with previously treated, advanced solid tumors.

Read the detailed description

This is a Phase 1/2, first in human (FIH), open-label, multicenter study of BHV-1510, a Trop-2 directed antibody-drug conjugate (ADC), in participants with previously treated, advanced solid tumors. The study comprises 2 parts: a Phase 1 Dose Escalation and a Phase 2 Dose Expansion. The Phase 1 will investigate the safety and tolerability of BHV-1510 given in monotherapy and given in combination with cemiplimab and identify one or more recommended doses for expansion (RDEs) and the maximum-tolerated dose (MTD) (if one exists). Once the RDE has been established, Phase 2 will open to investigate the preliminary efficacy of BHV-1510 in signal-finding expansion cohorts.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BHV-1510 and Cemiplimab in people with Solid Tumor, run by Biohaven Therapeutics Ltd. at 17 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Chief Medical Officer (203-404-0410, clinicaltrials@biohavenpharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Number of patients with adverse events (AEs) (time frame: Through study completion, estimated as an average of 47 months). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026.
