Study Summary

This is a Phase 1, first in human (FIH), Open-Label, Dose Escalation, Dose Expansion and Dose Optimization Study of BHV-1530 as Monotherapy and in Combination with Other Anti-Cancer Agents in Adult Participants with Advanced or Metastatic Solid Tumors

Medical Condition
The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.
Solid Tumor
Phase
The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
