Neoadjuvant MPDL3280A, Nab-paclitaxel and Carboplatin (MAC) in NSCLC

Study Overview
=================
Brief Summary
-----------------
This is a research study to test the effectiveness of nab-paclitaxel + carboplatin + MPDL3280A for treatment of non-small-cell lung carcinoma (NSCLC), which is a type of lung cancer. The study aims to determine if chemotherapy combined with immune-based therapy can lead to improvement in tumor response rates over historical response rates with chemotherapy alone.

Detailed Description
-----------------
Lung cancer is the most common cancer in both men and women worldwide, accounting for 13% of incident cancers. In 2015, it was estimated there would be 221,200 new lung cancers diagnosed in the United States, with 158,040 lung cancer deaths. Approximately 85% of all lung cancers are characterized as non-small cell lung cancer (NSCLC). Repeated studies have shown neoadjuvant cytotoxic chemotherapy to be safe prior to surgical resection of NSCLC with no difference in extent of surgical procedures performed, operative morbidity and mortality. The debate remains as to whether neoadjuvant or adjuvant chemotherapy is the best approach, with advantages and disadvantages to each. The investigators propose that new therapies such as immune checkpoint inhibitors that demonstrate promising clinical activity in the advanced disease setting must be incorporated into the neoadjuvant setting, in order to maximize benefit early in a patient's treatment course, and with a suitable surrogate endpoint that can be used to establish a preliminary efficacy signal, prior to initiation of a large confirmatory study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: MPDL3280A, Carboplatin, Nab-paclitaxel<br>Subjects with advanced or recurrent cancers receiving: MPDL3280A every 21 days for up to 84 days Carboplatin every 21 days for up to 84 days Nab-paclitaxel every 7 days for up to 84 days | Drug: MPDL3280A<br>* MPDL3280A is a human, Fc optimized, monoclonal antibody directed against the protein ligand programmed cell death-1 ligand 1 (PD-L1), with potential immune checkpoint inhibitory and antineoplastic activities. Atezolizumab binds to PD-L1, blocking its binding to and activation of its receptor programmed death 1 (PD-1) expressed on activated T-cells, which may enhance the T-cell-mediated immune response to neoplasms and reverse T-cell inactivation. MPDL3280A 1200 mg will be administered as a 60 minute IV infusion on first administration, then over 30 minutes subsequently if tolerated.<br>* Other names: RG7446;Drug: Carboplatin<br>* Carboplatin is a second-generation platinum compound with a broad spectrum of antineoplastic properties. Carboplatin contains a platinum atom complexed with two ammonia groups and a cyclobutane-dicarboxyl residue. This agent is activated intracellularly to form reactive platinum complexes that bind to nucleophilic groups, thereby inducing intrastrand and interstrand DNA cross-links, as well as DNA-protein cross-links. These carboplatin-induced DNA and protein effects result in apoptosis and cell growth inhibition. Carboplatin area under the curve (AUC)=6 will be administered as a 30 minute IV infusion immediately after nab-paclitaxel.<br>* Other names: Paraplatin-Aqueous (AQ);Drug: Nab-paclitaxel<br>* Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of the natural taxane paclitaxel with antineoplastic activity. Nab-paclitaxel binds to and stabilizes microtubules, preventing their depolymerization and so inhibiting cellular motility, mitosis, and replication. Nab-paclitaxel 100 mg/m2 will be administered as a 30 minute IV infusion.<br>* Other names: Abraxane;|
