Brief Summary:
This phase Ib trial studies the side effects and best dose of osimertinib and navitoclax when given together and to see how well they work in treating patients with previously treated epidermal growth factor receptor (EGFR)-positive non-small cell lung cancer that has spread to other places in the body (metastatic) or has not responded to previous treatment with initial EGFR kinase inhibitor. Osimertinib and navitoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description:


I. To determine the safety and tolerability of osimertinib (AZD9291) in combination with navitoclax in patients with EGFR-mutant non-small cell lung cancer (NSCLC) following resistance to prior EGFR-tyrosine kinase inhibitor (EGFR TKI).

II. To evaluate the feasibility of treatment with AZD9291 plus navitoclax for patients with T790M-mediated acquired resistance to EGFR TKI.


I. To study the pharmacokinetic profile of the combination of AZD9291 plus navitoclax.

II. To observe and record anti-tumor activity.


I. To study plasma genotype levels as a response biomarker in patients with EGFR-mutant lung cancer.

II. To explore tissue biomarkers of apoptosis and their association with treatment response.

OUTLINE: This is a phase Ib, dose-escalation study followed by a dose-expansion study.

Patients receive navitoclax orally (PO) once daily (QD) on days 1-28 and osimertinib PO QD on days 4-28 (days 1-28 during dose-expansion). Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Primary Outcome Measures :
  1. Incidence of toxicity (dose escalation) [ Time Frame: Up to 2 years ]
    Incidence of toxicity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03. Frequency and severity of adverse events will be tabulated using counts and proportions detailing frequently occurring, serious and severe events of interest. Adverse events will be summarized using all adverse events experienced, although a sub-analysis may be conducted including only those adverse events in which the treating physician deems possibly, probably or definitely attributable to one or both study treatments.

  2. Feasibility of the combination therapy in T790M+ lung cancer (dose expansion) [ Time Frame: Up to 12 weeks (3 cycles of treatment) ]
    Will be measured as at least 50% of patients achieving the expected dose duration and intensity. The proportion of patients completing 3 courses of therapy with > 75% of total dose of each drug will be quantified. The combination dosing will be considered potentially feasible if at least 50% of patients achieve the expected dose duration and intensity (95% confidence interval 30%-70%).

Secondary Outcome Measures :
  1. Pharmacokinetics parameters (maximum observed plasma drug concentration, area-under-the concentration-time-curve, trough drug concentration at steady state, and half-life) of osimertinib in combination with navitoclax [ Time Frame: Pre-dose, 1, 2, 4, 6, and 8 hours after navitoclax administration (day 3 of cycle 1 and day 1 of cycle 2) ]
    Pharmacokinetic calculations will incorporate consideration of the dosing change in navitoclax between the two measurement days.

  2. Objective response rate [ Time Frame: Baseline up to 30 days after completion of study drug ]
    Will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST). Calculated in the 20 patient expansion cohort and compared to the expected response rate of 61% in T790M+ lung cancer.

  3. Change in plasma concentration of EGFR T790M and other EGFR mutations [ Time Frame: Baseline to up to 2 years ]
    Change in plasma concentration of EGFR T790M and other EGFR mutations will be studied in an exploratory fashion and compared to tumor response on imaging.

  4. Biomarkers of apoptosis such as BCL2-like 1 (BCL-XL) and BCL2-like 11 (apoptosis facilitator) (BIM) levels in tumor tissue [ Time Frame: Baseline ]
    Biomarkers of apoptosis such as BCL-XL and BIM levels will be measured in tumor tissue and correlated with response in an exploratory fashion, under the hypothesis that navitoclax will have greater activity in cancers with high BCL-XL levels and inadequate apoptotic response.

  • Pregnant women are excluded from this study because AZD9291 and navitoclax have the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AZD9291 and navitoclax, breastfeeding should be discontinued if the mother is treated with AZD9291 and navitoclax
  • History of hypersensitivity to AZD9291 (or drugs with a similar chemical structure or class to AZD9291) or any excipients of these agents
  • Patients with human immunodeficiency virus (HIV) on antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with AZD9291
