A Phase 1b/2 Study of Serabelisib in Combination With Canagliflozin in Patients With Advanced Solid Tumors

May 20, 2020 updated by: Petra Pharma

A Phase 1b/2 Study of Serabelisib in Combination With Canagliflozin in Patients With Advanced Solid Tumors With PIK3CA or KRAS Mutations

This study aims to test the hypothesis that combining serabelisib, a PI3K alpha isoform inhibitor, with an SGLT2 inhibitor, canagliflozin will improve efficacy in the treatment of patients with advanced solid tumors.

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.

Detailed Description

This study aims to test the hypothesis that controlling the glucose/insulin feedback will enhance the efficacy of PI3K inhibition in treating solid tumors. The treatment consists of serabelisib, a PI3K alpha isoform (PI3Kα) inhibitor, combined with the sodium-glucose cotransporter-2 (SGLT2) inhibitor canagliflozin. The study will assess the safety and efficacy of the combination in adult patients with advanced solid tumors harboring mutations that may be dependent on PI3Kα activity: PIK3CA mutations and KRAS mutations.

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
