Pharmacokinetic and Safety Study of Pixantrone in Patients With Metastatic Cancer and Hepatic Impairment (Hepatic)

September 28, 2023 updated by: CTI BioPharma

A Non-randomized Cohort Study With Matched Controls Investigating Pharmacokinetic Parameters and Safety of a Single Dose of Pixantrone With Metastatic Cancer and Moderate, Severe, or No Hepatic Impairment.

This study will be conducted in patients with metastatic cancer and either moderate, severe, or no hepatic impairment who have failed other antineoplastic therapies or for whom there is no standard therapy. The study will be conducted in two stages. Using an existing pixantrone population pharmacokinetic (PPK) model, a model-based strategy will be used to evaluate the findings from the first stage of the study conducted in patients with moderate hepatic impairment and matched controls. The PPK evaluation will be completed prior to enrolling patients with severe hepatic impairment and additional matched controls during the second stage of the study. Patients with hepatic impairment will be paired with matched control patients with normal hepatic function, matched on gender, age, and body surface area (BSA).

Detailed Description

This study will be conducted in patients with metastatic cancer and either moderate, severe or no hepatic impairment who have failed other antineoplastic therapies or for whom there is no standard therapy. The study will be conducted in two stages. Stage I will include patients with moderate hepatic impairment and Stage II will include patients with severe hepatic impairment. An analysis of data from the Stage I portion of the study will be performed to decide whether to enroll patients in the Stage II portion of the study. Patients with hepatic impairment (either moderate or severe) will be paired with matched control patients with normal hepatic function, matched on gender, age, and body surface are (BSA). Patients will receive a single dose of pixantrone on day 1 of a 21 day cycle. Blood samples will be obtained at various time points during the first week of the first cycle for pharmacokinetic (PK) analysis. If any patient with hepatic impairment develops a dose limiting toxicity, subsequent patients will be administered a lower dose of pixantrone. If any patient with hepatic impairment who is receiving the reduced dose of pixantrone experiences a dose limiting toxicity, the study will be terminated. Patients who demonstrate any clinical, radiologic, or other evidence of response or stabilization after the initial dose of pixantrone and who wish to continue treatment may do so at the discretion of the Investigator. Patients receiving additional cycles will be treated with pixantrone every 21 days for up to 5 additional cycles and will be followed for safety only, until 30 days after the last dose.

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.

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

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
