Details and patient eligibility

About

The goal of the phase 1 study is to evaluate the safety, efficacy, pharmacokinetics, and pharmacodynamics activity of FP008 in subjects with advanced solid tumors.

Full description

This is a first-in-human (FIH), multicenter, open-label, dose escalation and dose expansion Phase 1 study of FP008 injection in subjects with advanced solid tumors. This study will evaluate the safety, tolerability, PK, PD, immunogenicity, and preliminary antitumor activity of FP008.

The study consists two parts: Part 1 (dose escalation phase) will evaluate the safety, tolerability, PK, PD, immunogenicity, and preliminary antitumor activity of FP008 treatment, and to estimate the DRDE(s) of FP008. Part 2 (Dose expansion phase) will evaluate the safety, tolerability, PK, PD, immunogenicity, and efficacy at the different DRDE(s)/schedule(s) of FP008 in subjects with selected advanced solid tumors.

Enrollment: 108 estimated patients

6. Subjects with diagnosis of immunodeficiency, organ transplant requiring immunosuppressive therapy, or allogeneic bone marrow or hematopoietic stem cell transplant.
7. Daily requirement for corticosteroids within 2 weeks prior to first dose of FP008.
8. Any other medical disorder, physical exam finding, laboratory finding, altered mental status, or psychiatric condition that the investigator considers unsuitable for participation in the study.
9. Cardiovascular dysfunction or clinically significant cardiac disease.
