Study Summary

This trial is testing a new cancer drug, inavolisib, for safety and how well it works in patients with PIK3CA-mutant solid tumors. It will be given as a single agent or in combination with other standard-of-care cancer treatments.

Who is the study for?
This trial is for adults with advanced or metastatic solid tumors, including breast cancer, that have a specific mutation (PIK3CA). Participants must be in good physical condition (ECOG 0 or 1) and expected to live at least 12 weeks. Women with hormone receptor-positive/HER2-negative or HER2-positive breast cancer are eligible. Key exclusions include recent other cancers, significant heart conditions, uncontrolled illnesses, prior treatments with certain drugs, and inability to swallow pills.Check my eligibility
What is being tested?
The study tests the drug Inavolisib alone or combined with standard therapies for advanced breast cancer. It's an open-label Phase I trial with two stages: dose-escalation to find safe amounts of Inavolisib and expansion to see how well it works across seven different treatment combinations involving drugs like Palbociclib, Letrozole, Fulvestrant, Metformin, Trastuzumab and Pertuzumab.See study design
What are the potential side effects?
Possible side effects may include digestive issues; changes in blood counts affecting liver and kidney function; fatigue; reactions related to the heart such as irregular heartbeat; potential interactions leading to increased risk of infection due to immune system effects; skin reactions; and symptoms from nervous system involvement.

9Treatment groups
Experimental Treatment
Group I: Stage II Arm G: Inavolisib + Trastuzumab + PertuzumabExperimental Treatment3 Interventions
Participants will receive inavolisib in combination with trastuzumab and pertuzumab (Days 1-21). Dose of inavolisib will be determined from the results of Stage I Arm A. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group II: Stage II Arm F: Inavolisib + Palbociclib + Fulvestrant + MetforminExperimental Treatment4 Interventions
Participants will receive inavolisib (Days 1-28) in combination with palbociclib (Days 1-21), fulvestrant (Days 1 and 15 of Cycle 1; Day 1 for subsequent cycles) and metformin (Days 1-28)(Cycle = 28 days). Dose of inavolisib will be determined from the results of Stage I Arm B. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group III: Stage II Arm E: Inavolisib + Palbociclib + FulvestrantExperimental Treatment3 Interventions
Participants will receive inavolisib (Days 1-28) in combination with palbociclib (Days 1-21) and fulvestrant (Days 1 and 15 of Cycle 1; Day 1 for subsequent cycles)(Cycle = 28 days). Dose of inavolisib will be determined from the results of Stage I Arm B. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group IV: Stage II Arm D: Inavolisib + FulvestrantExperimental Treatment2 Interventions
Participants will receive inavolisib on Days 1-28 in combination with fulvestrant on Day 1 and 15 of Cycle 1 and then on Day 1 from Cycle 2 (cycle length: 28 days). Dose of inavolisib will be decided based on the results of Stage I Arm C. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group V: Stage II Arm C: Inavolisib + LetrozoleExperimental Treatment2 Interventions
Participants will receive inavolisib in combination with letrozole on Days 1-28 of each 28-day cycle. Dose of inavolisib will be decided based on the results of Stage I Arm C. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group VI: Stage II Arm B: Inavolisib + Palbociclib + LetrozoleExperimental Treatment3 Interventions
Participants will receive inavolisib on Days 1-28 in combination with palbociclib on Days 1-21 and letrozole on Days 1-28 of each 28-day cycle. Dose of inavolisib will be decided based on the results of Stage I Arm B. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group VII: Stage I Arm C: Inavolisib + LetrozoleExperimental Treatment2 Interventions
Participants will receive inavolisib in escalating dose levels along with letrozole on Days 1-28 of each 28-day cycle. The starting dose of inavolisib will not exceed the starting dose in Stage I Arm A. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group VIII: Stage I Arm B: Inavolisib + Palbociclib + LetrozoleExperimental Treatment3 Interventions
Participants will receive inavolisib in escalating dose levels (starting dose 3 mg) on Days 1-28, palbociclib on Days 1-21, and letrozole on Days 1-28 of each 28-day cycle. Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
Group IX: Stage I Arm A: Inavolisib Single AgentExperimental Treatment1 Intervention
Participants will receive inavolisib in escalating dose levels with starting dose of 6 milligrams (mg). Participants will receive single dose of inavolisib on Day 1 of Cycle 1 followed by once daily from Day 8 of Cycle 1. (Cycle length: 35 days for Cycle 1 and 28 days for all other cycles). Participants will continue treatment until the end of the study in the absence of unacceptable toxicities and unequivocal disease progression.
