Study of FP-1039 in Subjects With Endometrial Cancers

December 9, 2021 updated by: Five Prime Therapeutics, Inc.

An Open-Label Phase 2 Pilot Study Evaluating the Activity and Safety of FP 1039 in Subjects With Advanced and/or Recurrent Endometrial Cancers With Specific FGFR2 Mutations

An open-label, non-randomized, single arm study to assess the safety, tolerability, and pharmacokinetics of FP-1039 given by weekly intravenous (IV) administrations in advanced endometrial cancer patients with FGFR2-specific mutations. FP-1039 will be dosed weekly starting at a dose of up to 16 mg/kg.

Conditions

Conditions

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

FP-1039 will be administered intravenously over 30 minutes once a week. All enrolled subjects will be monitored for the occurrence of unacceptable toxicity. Subjects with no evidence of disease progression or unacceptable toxicity after 4 doses of FP-1039 may continue to receive weekly treatment provided there continues to be no evidence of disease progression or unacceptable toxicity. Dosing will be discontinued if a subject has evidence of disease progression. Disease will be assessed approximately every 2 months.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

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.
  • Phase 2

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

    • Any other investigational therapy within 28 days of the first scheduled dose of FP-1039 Note: Any eligibility questions related to prior therapies including the timing from prior therapies should be discussed and a decision agreed on by the Investigator and the Sponsor in writing prior to the subject entering the study
  3. Known hypersensitivity to the components of FP-1039
  4. Current anticoagulation with therapeutic doses of warfarin (low-dose warfarin ≤ 1mg/day is permitted)
  5. PT/INR and/or PTT test results at screening that are above 1.3 x the laboratory ULN.

  8. History of organ, bone marrow, or stem cell transplantation
  9. Pregnant or breast feeding
  10. Clinically apparent CNS metastases or carcinomatous meningitis Note: Subjects with CNS metastases who have completed a course of radiotherapy and who have been on a stable dose of glucocorticoids for at least 4 weeks are eligible.
  11. Uncontrolled intercurrent illness including but not limited to an active infection, hypertension, psychiatric, or substance abuse disorders that would preclude consent, limit compliance with study requirements, or confound safety interpretation.
  12. Unable or unwilling to abide by the study protocol or cooperate fully with the Investigator or designee

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
