Study Summary

This is a Phase I, first in human (FIH), open-label, multicenter study of BHV-1530 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.

    Requirements information
    Inclusion criteria
    • Signed, written Independent Ethics Committee (IEC)/Institutional Review Board (IRB)-approved informed consent
    • Age greater than or equal to 18 years
    • Patients with histologically or cytologically confirmed locally advanced/metastatic relapsed or refractory solid tumors as outlined below:
    • Dose-escalation and Dose-expansion (Backfill) Cohorts:
    • Any patient for which FGFR3 is potentially important to the biology of the disease, and who has progressed following or is intolerant of standard-of-care therapy or for which no standard therapy is available
    • Confirmation of FGFR3 positivity (FGFR3 mutation, rearrangement, amplification and overexpression) is not required prior to enrollment on the study
    • Patient consent to provide tumor tissue collected prior to study treatment, preferably from a biopsy performed after their last anticancer therapy and within 90 days of the start of study treatment. An older archival sample may be acceptable with Sponsor approval
    • Dose Confirmation Cohort:
    • Any patient for which FGFR3 is important to the biology of the disease, and disease OR a patient with a cancer type in which a signal of potential efficacy was identified in dose escalation and dose expansion (as clarified in a protocol amendment), AND
    • who has progressed following or is intolerant of standard-of-care therapy or for which no standard therapy is available; AND
    • FGFR3 Status:
    • Locally- or centrally-determined, or documented overexpression or alterations of FGFR3
    • Measurable advanced or metastatic tumors per RECIST 1.1 criteria
    • Patients must exhibit an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
    • Acceptable liver function:
    • Bilirubin ≤ 1.5 × upper limit of normal (ULN). Participants with known Gilbert's syndrome who have total bilirubin level ≤3×ULN may be enrolled.
    • AST, ALT, and alkaline phosphatase ≤ 2.5 × ULN (if liver metastases are present, then ≤ 5 × ULN is allowed)
    • Acceptable renal function:
    • • Serum creatinine ≤1.5 × ULN, or creatinine clearance ≥50 mL/min as calculated using the modified Cockcroft-Gault equation; confirmation of creatinine clearance is only required when creatinine is >1.5 × ULN; 24-hour urine collection is allowed, but not required
    • Acceptable hematologic status:
    • Blood transfusion or growth factor support is not allowed within 7 days prior to blood samples that will be used to establish eligibility
    • Absolute neutrophil count greater than or equal to 1500/mm3. Participants with known Duffy null phenotype who have absolute neutrophil count ≥ 1,200/mm3 may be enrolled
    • Platelet count greater than or equal to 100,000 mm3
    • Hemoglobin greater than or equal to 9 g/dL
    • 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
    • A negative urine or serum pregnancy test (if a woman of childbearing potential);
    • Women of childbearing potential and men must agree to use adequate contraception prior to study entry, for the duration of study participation and for 7 months (for women) or 4 months (for men) after the last dose of study drug.
    Exclusion criteria
    • Prior treatment with antibody drug conjugate (ADC) with a topoisomerase-I inhibitor payload. Prior direct treatment with topoisomerase inhibitor (e.g., irinotecan, topotecan, belotecan, nano-liposomal irinotecan) are not exclusionary.
    • Participant has clinically significant intercurrent disease including, but not limited to:
    • New York Heart Association Class III or IV heart failure
    • Myocardial infarction, unstable angina, or stroke within 3 months prior to C1D1
    • Newly diagnosed thromboembolic events that require therapeutic intervention within 6 months prior to C1D1 (participants with stable control of lower limb deep venous thrombosis over at least 3 months are allowed)
    • Severe aortic stenosis
    • Uncontrolled arrhythmia
    • Symptomatic pericardial effusion
    • Congenital long QT syndrome
    • A mean of Fredericia's formula-QT corrected interval (QTcF) prolongation to >470 msec based on a 12-lead ECG
    • Uncontrolled hypertension (systolic blood pressure ≥180 mmHg and/or diastolic blood pressure ≥110 mmHg) or diabetes (hemoglobin A1C ≥9.0%)
    • Left ventricular ejection fraction (LVEF) <45% determined by echocardiogram or multiple gated acquisition scan (MUGA)
    • Symptomatic pleural effusion (<90% oxygen saturation)
    • Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy
    • Primary central nervous system (CNS) tumors, current or previously treated leptomeningeal disease or known active brain metastases.
    • NOTE: Participants with previously treated, clinically stable, radiologically stable brain metastases maybe eligible
    • Pregnant or nursing women
    • Any standard cancer therapy (e.g., chemotherapy, hormonal therapy, radiotherapy, immunotherapy, biologic therapy treatment) or experimental therapy within 4 weeks or 5 half-lives, whichever is shorter, prior to C1D1. The interval may be reduced to 2 weeks for bone-only radiation therapy. Any major surgical procedure within 6 weeks prior to C1D1
    • Participants have not recovered (i.e., improvement to Grade 1 or better) from all acute toxicities from previous therapy, excluding alopecia and vitiligo. If the participant has an ongoing, stable, chronic Grade 2 toxicity they may be eligible after discussion with Sponsor on a case-by-case basis
    • Any clinically significant corneal or retinal abnormality that may increase the risk of eye toxicity
    • Known active infection with human immunodeficiency virus (HIV), human T-cell leukemia virus, type 1 (HTLV-1), hepatitis B virus (HBV), or hepatitis C virus (HCV), if allowed by local regulations:
    • Participants with hepatitis B (hepatitis B virus surface antigen [HbsAg] positive), or hepatitis C (hepatitis C virus [HCV] antibody positive, confirmed by HCV ribonucleic acid). Participants with HCV with undetectable virus after treatment are eligible. Participants with a prior history of hepatitis B virus are eligible if quantitative polymerase change reaction for hepatitis B virus DNA is negative
    • Participants with human immunodeficiency virus (HIV) infection with acquired immune deficiency syndrome (AIDS) defining illness are not eligible for enrollment; however, participants who have had HIV infection and who have a cluster of differentiation 4 (CD4) + T cell count >350 cells/L and no history of an AIDS-defining illness are eligible for entry
    • Has an active second malignancy. Note: participants with a history of malignancy that have been completely treated, with no evidence of active cancer for 3 years prior to enrollment, or participants with surgically cured tumors with low risk of recurrence (e.g., nonmelanoma skin cancer, histologically confirmed complete excision of carcinoma in situ) are allowed
    • Participants who in the opinion of the Investigator will not be able to adhere to the schedule of assessments and/or may have difficulties complying with the treatment regimen or are unwilling or unable to comply with procedures required in this protocol
    • Known sensitivity to BHV-1530 or any of the excipients in BHV-1530;
    • History of (noninfectious) clinically significant interstitial lung disease (ILD)/pneumonitis that required steroids, active clinically significant ILD/pneumonitis, or suspected clinically significant ILD/pneumonitis that cannot be ruled out by imaging at screening.
    • Requires supplemental oxygen for daily activities
    • Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study treatment
