Five Prime Therapeutics

Status and phase: Completed; Phase 1

Conditions: Gastric Cancer; Transitional Cell Carcinoma of the Bladder; Advanced Solid Tumors

Study type: Interventional

Funder types: Industry

Identifiers

FPA144-001

Details and patient eligibility

About

This is a three-part, open-label, safety, tolerability, and PK study of FPA144. Patients will be enrolled in Part 1 (A or B, dose escalation) or Part 2 (dose expansion) of the study, but not both.

Full description

Part 1A is a dose-escalation study in patients with any locally advanced or metastatic solid tumor or lymphoma for which standard therapies have been exhausted. Part 1B will further assess safety and evaluate PK of FPA144 in gastric cancer patients.

Part 2 patients will be enrolled and treated in order to further characterize safety and preliminary efficacy in a selected cancer patient population with the greatest potential for clinical benefit from FPA144 treatment.

Enrollment: 79 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Life expectancy of at least 3 months

• ECOG performance status of 0 to 1

  • In sexually-active patients, willingness to use 2 effective methods of contraception

• Adequate hematological and organ function, confirmed by lab values

• Tumor tissue must be available for prospective determination of FGFR2b overexpression

  • Locally recurrent or metastatic disease that has progressed on or following standard treatment, or is not a candidate for standard treatment
  • Histologically or cytologically confirmed transitional cell carcinoma of the genitourinary tract
  • Measurable disease as defined by RECIST version 1.1

Exclusion criteria

• Untreated or symptomatic central nervous system (CNS) metastases

• Impaired cardiac function or clinically significant cardiac disease

  • Treatment with any anticancer therapy or participation in another therapeutic clinical study with investigational drugs </=14 days (</=28 days for patients in Korea) prior to first dose of FPA144

• Ongoing acute adverse effects from prior anticancer or investigational therapy > NCI CTCAE Grade 1

• Retinal disease or a history of retinal disease or detachment

• Females who are pregnant or breastfeeding; women of childbearing potential must not be considering getting pregnant during the study

  • Presence of any serious or unstable concomitant systemic disorder incompatible with the clinical study

• Known allergy or hypersensitivity to components of the FPA144 formulation including polysorbate

• History of prior malignancy except:

• a) Curatively treated non-melanoma skin cancer or

• b) Solid tumor treated curatively more than 5 years previously without evidence of recurrence or

• c) History of other malignancy that in the Investigator's opinion would not affect the determination of study treatment effect

• Prior treatment with any selective inhibitor (e.g., AZD4547, BGJ398, JNJ-42756493, BAY1179470) of the FGF-FGFR pathway
