A Study Evaluating Targeted Therapies in Participants Who Have Advanced Solid Tumors With Genomic Alterations or Protein Expression Patterns Predictive of Response

Summary

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.

Conditions

• Advanced Unresectable or Metastatic Solid Malignancy

Interventions

DRUG

Entrectinib

Entrectinib will be self-administered by participants orally at home (except on clinic days), at the same time each day, on a starting dose of 600 milligrams (mg) per day once a day (QD) until disease progression, intolerable toxicity, or consent withdrawal.

DRUG

Inavolisib

Inavolisib will be self-administered by participants orally at home (except on clinic days) at the same time each day, on a starting dose of 9 mg/day QD until disease progression, intolerable toxicity, or consent withdrawal.

DRUG

Alectinib

Alectinib will be self-administered by participants orally at home (except on clinic days), at the same times each day, on a starting dose of 600 mg twice a day (BID) until disease progression, intolerable toxicity, or consent withdrawal.

DRUG

Ipatasertib

Ipatasertib will be self-administered by participants orally at home (except on clinic days), at the same time each day, on a starting dose of 400 mg QD until disease progression, intolerable toxicity, or consent withdrawal.

DRUG

Atezolizumab

Atezolizumab will be administered by intravenous (IV) infusion at a fixed dose of 1200 mg for participants on Day 1 of each 21-day cycle until unacceptable toxicity or progressive disease (or loss of clinical benefit).

DRUG

Trastuzumab Emtansine

Trastuzumab emtansine will be administered at 3.6 mg per kilogram (kg) of body weight by IV infusion every 21 days (unless dose reduction and/or dose delays are required) until disease progression or unacceptable toxicity.

DRUG

Pertuzumab, Trastuzumab, and Hyaluronidase-zzxf

PH FDC SC will be administered subcutaneously (SC) at a fixed non-weight-based dose. A loading dose of 1200 mg SC pertuzumab and 600 mg SC trastuzumab is then followed by a maintenance dose of 600 mg SC pertuzumab and 600 mg SC trastuzumab once every 3 weeks.

DRUG

Tucatinib

Tucatinib 300 mg will be administered orally BID continuously starting from Cycle 1 Day 1 onwards.

DRUG

Investigator's Choice of Chemotherapy

Chemotherapy will consist of docetaxel, paclitaxel, or capecitabine, as determined by the investigator, and will be administered per the respective package insert and institutional guidelines.

DRUG

Paclitaxel

The dose of paclitaxel is 80 mg/m2 administered by IV infusion on Days 1, 8, and 15 of each 28-day cycle. The paclitaxel infusion will be delivered over at least 60 minutes for each dose per institutional guidelines and administered after the oral dose of ipatasertib.

DRUG

Tiragolumab

Following the administration of atezolizumab and an observation period, participants will receive 600 mg tiragolumab at a fixed dose administered by IV infusion on Day 1 of each 21-day cycle.

DRUG

Pralsetinib

Pralsetinib will be self-administered by participants orally at home (except on clinic days), at the same time each day, on a starting dose of 400 mg/day (four 100-mg capsules per day) once a day (QD) until disease progression, intolerable toxicity, or consent withdrawal.
