This is a phase I/Ib, open-label, single-center, single-arm study of alisertib and osimertinib for patients with stage IV EGFR-mutated lung cancer, incorporating both a dose escalation and dose-expansion phase

Official Title

A Phase I/Ib Study of Alisertib in Combination With Osimertinib in Metastatic EGFR-mutant Lung Cancer


The dose-escalation phase will consist of a modified 3+3 dose escalation and will be open to patients with metastatic lung cancer with an activating EGFR mutation who have progressed on and are currently receiving osimertinib therapy. The dose-escalation and expansion phases will be open to patients who have received any number of therapies as long as they are currently being treated with and tolerating osimertinib 80 mg orally once per day, and who have demonstrated radiographic progression by RECIST 1.1 criteria on their most recent scan. Primary Objective: To determine the safety and tolerability of the combination osimertinib + alisertib in patients with advanced EGFR-mutant NSCLC and identify a recommended phase II dose. Secondary Objectives: 1. To evaluate the clinical efficacy of adding alisertib to osimertinib compared to "historical" data of platinum doublet chemotherapy in patients who have progressed on osimertinib monotherapy. 2. To explore tumor biomarkers, including TPX2, that predict response to osimertinib + alisertib. 3. To evaluate alisertib and osimertinib pharmacokinetics 4. To evaluate the CNS response rate of alisertib + osimertinib Patients may continue treatment indefinitely until disease progression, intolerance, or other contraindication to study treatment.

Open to people ages 18 years and up

  1. Patients must have histologically confirmed stage IV lung cancer (patients with both non-small cell lung cancer and cancer that has transformed to small cell lung cancer at osimertinib progression will also be considered eligible if osimertinib treatment is planned to continue post-progression).

  5. Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
  6. Clinical laboratory values as specified below within 7 days before the first dose of study drug (if applicable):
  7. Absolute neutrophil count (ANC) > 1500/mm³
  8. Absolute lymphocyte count > 500 mm3
  9. Platelets > 100,000/mm³
  10. Hgb > 9 g/dL. Values must be obtained without need for red blood cell transfusion support within 14 days. However, erythrocyte growth factor is allowed as per published American Society of Clinical Oncology (ASCO) guidelines.
  11. Total bilirubin ≤ 1.5 x upper limit of normal (ULN), or direct bilirubin ≤ 1.5 x ULN for patients with Gilbert's syndrome.
  12. Serum glutamic-oxaloacetic transaminase (SGOT) / aspartate aminotransferase (AST) and serum glutamic-pyruvic transaminase (SGPT) / alanine aminotransferase (ALT) < 2.5 x ULN. AST and/or ALT may be up to 5 x ULN if with known liver metastases.
  13. Renal function as defined by calculated creatinine clearance ≥30 ml/min (Cockcroft-Gault Formula).
  14. Willing to provide blood and tissue for correlative research purposes
  15. Willing to undergo pre-treatment research biopsy, OR donate archived tissue from a biopsy performed within 30 days of the first dose of study drug is available
  16. Female patients who:
  17. Are postmenopausal (see Appendix 6) for at least 1 year before the screening visit, OR
  18. Are surgically sterile, OR
  19. If they are of childbearing potential, agree to practice 1 highly effective method of contraception and 1 additional effective (barrier) method at the same time (see Appendix 6), from the time of signing the informed consent through 180 days after the last dose of study drug, OR
  20. Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.)
  21. . Male patients, even if surgically sterilized (i.e., status post-vasectomy), who:
  22. Agree to practice effective barrier contraception during the entire study treatment period and through 120 after the last dose of study drug, OR
  23. Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.)
  24. . Voluntary written consent must be given before performance of any study-related procedure not part of standard of care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
  25. . Currently receiving and tolerating osimertinib 80 mg PO daily with no current grade 2 or greater AE attributable to osimertinib.
  26. . Evidence of disease progression on imaging (computerized tomography (CT) scan, magnetic resonance imaging (MRI), or Positron Emission Tomography (PET) CT within the last 30 days.
