One-year, Open Extension to Evaluate the Treatment of Patients With Castration-Resistant Prostate Cancer With YONSA™

November 18, 2021 updated by: Sun Pharmaceutical Industries Limited

An Open-Label, Single-Arm, Multiple Center Extension Study to Evaluate One Year of Treatment of Patients With Metastatic Castration-Resistant Prostate Cancer With YONSA™ 500 mg (4 x 125 mg qd) With Methylprednisolone (4 mg Bid)

This is an open-label, single-arm, multi-center extension study to evaluate safety in patients with mCRPC of YONSA 500 mg (4 x 125 mg qd) with methylprednisolone (4 mg bid). Patients will have successfully completed an 84-day treatment with abiraterone acetate in a previous trial. Results from the final visit of the previous study will be used to determine patient's eligibility for this study. Patients in this study will be eligible to receive open-label YONSA with methylprednisolone for up to 12 months. Pharmacodynamic parameters of serum testosterone and PSA levels will be monitored. Disease progression will be assessed by PCWG2 criteria.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

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

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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
