Trial ID Title Status Sponsor Phase Start Date Summary
NCT03006172 ↗ To Evaluate the Safety, Tolerability, and Pharmacokinetics of Inavolisib Single Agent in Participants With Solid Tumors and in Combination With Endocrine and Targeted Therapies in Participants With Breast Cancer Recruiting Genentech, Inc. Phase 1 2016-12-13 This is an open-label, multicenter, Phase I study designed to evaluate the safety, tolerability, and pharmacokinetics of inavolisib administered orally as a single agent in patients with locally advanced or metastatic PIK3CA-mutant solid tumors, including breast cancer, and in combination with standard-of-care endocrine and/or targeted therapies for the treatment of locally advanced or metastatic PIK3CA-mutant breast cancer. Participants will be enrolled in two stages: a dose-escalation stage (Stage I) and an expansion stage (Stage II). Participants will be assigned to one of seven regimens: inavolisib as a single agent (Arm A), inavolisib in combination with palbociclib and letrozole (Arm B), inavolisib in combination with letrozole (Arm C), inavolisib in combination with fulvestrant (Arm D), inavolisib in combination with palbociclib and fulvestrant (Arm E), inavolisib in combination with palbociclib, fulvestrant, and metformin (Arm F), and inavolisib in combination with trastuzumab and pertuzumab (and letrozole or fulvestrant, if applicable (Arm G)).
NCT04191499 ↗ A Study Evaluating the Efficacy and Safety of Inavolisib + Palbociclib + Fulvestrant vs Placebo + Palbociclib + Fulvestrant in Patients With PIK3CA-Mutant, Hormone Receptor-Positive, Her2-Negative, Locally Advanced or Metastatic Breast Cancer Recruiting Hoffmann-La Roche Phase 2/Phase 3 2020-01-29 This study will evaluate the efficacy, safety, and pharmacokinetics of inavolisib in combination with palbociclib and fulvestrant compared with placebo plus palbociclib and fulvestrant in patients with PIK3CA-mutant, hormone receptor (HR)-positive, HER2-negative locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.
NCT04589845 ↗ Tumor-Agnostic Precision Immuno-Oncology and Somatic Targeting Rational for You (TAPISTRY) Platform Study Recruiting Hoffmann-La Roche Phase 2 2021-01-18 TAPISTRY is a Phase II, global, multicenter, open-label, multi-cohort study designed to evaluate the safety and efficacy of targeted therapies or immunotherapy as single agents or in rational, specified combinations in participants with unresectable, locally advanced or metastatic solid tumors determined to harbor specific oncogenic genomic alterations or who are tumor mutational burden (TMB)-high as identified by a validated next-generation sequencing (NGS) assay. Participants with solid tumors will be treated with a drug or drug regimen tailored to their NGS assay results at screening. Participants will be assigned to the appropriate cohort based on their genetic alteration(s). Treatment will be assigned on the basis of relevant oncogenotype, will have cohort-specific inclusion/exclusion criteria, and, unless otherwise specified, will continue until disease progression, loss of clinical benefit, unacceptable toxicity, participant or physician decision to discontinue, or death, whichever occurs first.
NCT04632992 ↗ A Study Evaluating Targeted Therapies in Participants Who Have Advanced Solid Tumors With Genomic Alterations or Protein Expression Patterns Predictive of Response Recruiting Genentech, Inc. Phase 2 2021-01-13 This is a Phase II, multicenter, non-randomized, open-label, multi-arm study designed to evaluate the safety and efficacy of targeted therapies as single agents or in rational, specified combinations in participants with advanced unresectable or metastatic solid tumors determined to harbor specific biomarkers. Patients will be enrolled based on local testing performed at a Clinical Laboratory Improvement Amendments (CLIA)-certified or equivalently accredited diagnostic laboratory. The multi-arm structure of the MyTACTIC study allows patients with solid tumors to be treated with a drug or drug regimen tailored to their biomarker identified at screening.
NCT04802759 ↗ A Study Evaluating the Efficacy and Safety of Multiple Treatment Combinations in Participants With Breast Cancer Recruiting Hoffmann-La Roche Phase 1/Phase 2 2021-06-20 This is a Phase Ib/II, open-label, multicenter, randomized umbrella study in participants with breast cancer. The current cohort (Cohort 1) will focus on participants with inoperable, locally advanced or metastatic, estrogen receptor (ER)-positive breast cancer who had disease progression during or following treatment with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i; e.g., palbociclib, ribociclib, abemaciclib) in the first- or second-line setting. The study is designed with the flexibility to open new treatment arms as new treatments become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, or modify the patient population.
