A Phase Ib Study of the Safety and Pharmacology of MPDL3280A Administered with Erlotinib in Patients with Advanced Non-Small Cell Lung Cancer
Diseases and Conditions Researched
What is the purpose of this trial?
This open-label, multicenter study will assess the safety, tolerability, and pha rmacokinetics of intravenous (IV) dosing of MPDL3280A and oral dosing of Tarceva (erlotinib) administered in combination to patients with non-small cell lung ca ncer (NSCLC). This study has two stages. In the safety evaluation stage, patients with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) -treatment-naive, advanced NSCLC will be given Tarceva at a starting daily dose of 150 mg for 28 consecutive days during Cycle 1 and for 21-day cycles thereafte r. The starting dose of MPDL3280A will be 1200 mg, administered every 3 weeks st arting on Day 8 of Cycle 1. If the starting regimen is not tolerated, alternativ e doses and/or schedules of Tarceva and MPDL3280A may be tested. In the expansi on stage, patients with previously untreated, EGFR mutation-positive, advanced N SCLC will be treated with a potential recommended phase 2 dose and schedule base d on the treatment established in safety evaluation stage. For both stages, con tinuation of treatment beyond Cycle 1 will be at the discretion of the treating investigator. In the absence of unacceptable toxicity or disease progression, tr eatment with MPDL3280A may be continued for a maximum of 17 cycles (or 12 months, whichever occurs first). Tarceva may be continued until disease progression in the absence of unacceptable toxicity. Time on study is expected to be approxima tely 15 months.

How will my information be used?
When you express interest in a specific study, the information from your profile will be sent to the doctor conducting that study. If you're eligible to participate, you may be contacted by a nurse or study coordinator.
If you select a health category rather than a specific study, doctors who have active studies in that area may contact you to ask if you would like to participate.
In both cases, you will be contacted by the preferred method (email or phone) that you specified in your profile.
