Open Label Dose-Finding Study of TRC105 Plus Capecitabine for Metastatic Breast Cancer (TRC105)

February 28, 2019 updated by: Tracon Pharmaceuticals Inc.

An Open Label Phase 1B Dose-Finding Study of TRC105 in Combination With Capecitabine for Progressive or Recurrent Metastatic Breast Cancer

The purpose of this study is to determine the recommended phase 2 dose and overall safety and tolerability of TRC105 when given in combination with capecitabine for the treatment of patients with progressive or recurrent metastatic breast cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

All patients were required to sign a consent form prior to undertaking any study-related procedures. Prospective patients were screened to determine if they qualified for the study within 28 days of enrollment. Patients who qualified received TRC105 i.v. over 1 to 4 hours on Day 1, Day 4, Day 8 and Day 15 of the initial 21-day cycle and Day 1, Day 8 and Day 15 of every subsequent 21-day cycle in combination with 1000 mg/m2 capecitabine BID for 14 days of each 21-day cycle. Those who tolerated TRC105 without any infusion reactions were eligible for reduced infusion durations. After 3 cycles of treatment, patients who demonstrated a response of complete response (CR), partial response (PR) or stable disease (SD) were eligible for additional treatment for up to six months (9 total cycles). Upon discussion with TRACON, patients judged by the Principal Investigator to be benefiting from treatment were able to continue treatment on this protocol beyond six months.

Toxicities were graded according to the NCI CTCAE Version 4.0. Patients who exited the study for reasons other than drug-related toxicity prior to completion of the first 21-day cycle were replaced. Intra-patient dose escalation was not allowed.

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.

Eligibility Criteria

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.
