Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male or female participants aged ≥18 years.
* Unresectable, incurable, locally advanced or metastatic epithelial-origin solid tumor that is refractory to standard therapies, or has no approved standard therapies, or no approved standard therapies at its current treatment stage. If applicable to the tumor type, participants must have received platinum-based chemotherapy, standard of care immunotherapy, and standard of care targeted therapies.
* Measurable disease (per RECIST 1.1).
* Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1.
* Participants have adequate hematologic, renal, liver, and coagulation function as defined by the following (blood transfusion or growth factor support is not allowed within 7 days prior to blood samples that will be used to establish eligibility):

* Hemoglobin ≥9 g/dL
* Absolute neutrophil count \>1,500/mm3; participants with known Duffy null phenotype who have absolute neutrophil count ≥1,200/mm3 may be enrolled
* Platelets \>100,000/mm3
* Creatinine clearance ≥50 mL/min measured or estimated using the Cockcroft-Gault formula; 24-hour urine collection is allowed, but not required.
* Total bilirubin ≤1.5 × upper limit of normal (ULN); participants with known Gilbert's syndrome who have total bilirubin level ≤3×ULN may be enrolled.
* Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \<2.5×ULN (or ≤5×ULN for participants with hepatic metastases)
* Alkaline phosphatase \<2.5×ULN (or ≤5×ULN for participants with hepatic and/or bone metastases)
* International normalized ratio (INR) or prothrombin time (PT) ≤1.5×ULN
* Activated partial thromboplastin time (aPTT) ≤1.5×ULN. Study participants on therapeutic doses of anticoagulation medication must have INR and/or aPTT ≤ the upper limit of the therapeutic range for intended use
* Have recovered (ie, improvement to Grade 1 or better) from all acute toxicities from previous therapy, excluding alopecia and vitiligo.


* histologically or cytologically documented advanced (locally, recurrent, inoperable, cannot be treated with curative intent) or metastatic cancer.
* received ≤ 2 prior lines of systemic anti-cancer therapy and at most one prior anti-programmed cell death protein 1 (PD-1) (programmed death-ligand 1 \[PD-L1\]) therapy for advanced/ metastatic disease.

Exclusion Criteria

* Women who are pregnant or lactating.
* Clinically significant intercurrent disease.
* Has symptomatic brain metastases or has had any radiation or surgery for brain metastases within 4 weeks of C1D1.
* Has clinically significant corneal disease.
* Requires supplemental oxygen for daily activities.
* Previous treatment with a Trop-2-targeted therapy, including Trop-2 ADCs.
* Has a medical history of interstitial lung disease (eg, noninfectious interstitial pneumonia requiring steroid treatment, pneumonitis, pulmonary fibrosis, or severe radiation pneumonitis) or current interstitial lung disease or are suspected to have any of these diseases based on imaging at Screening.
* Any standard cancer therapy (eg, chemotherapy, hormonal therapy, radiotherapy, immunotherapy, biologic therapy treatment) or experimental therapy within 3 weeks or 5 half-lives, whichever is shorter, prior to C1D1.
