Study Endpoints
Primary Endpoints
Determination of Maximum Tolerated Dose (MTD) (Cohort A)
First 28 days of study treatment (1 cycle is 28 days)

The MTD is the highest dose at which no more than one instance of a dose-limiting toxicity is observed among the 6 participants treated.

Proportion of patients experiencing dose limiting toxicity (DLT) (Cohort A)
First 28 days of study treatment (1 cycle is 28 days)

Less than or at least 1 out of 6 at highest dose level below the maximal administered dose. If 0 of these 3 additional participants experience a dose limiting toxicity (DLT) (1 of 6), proceed to the next dose level. If 1 or more of the 3 additional participants experience DLT (2 of 6), then dose escalation is stopped, and this dose is declared the maximal administered dose (highest dose administered). Three (3) additional participants will be entered at the next lowest dose level if only 3 participants were treated previously at that dose.

Proportion of patients experiencing serious adverse event (SAE)
Up to 2 years

The proportion of participants experiencing an adverse event classified as an SAE will be reported by grade and type according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5, with exact 95% confidence intervals

Secondary Endpoints
Overall Response Rate (ORR)
Up to 2 years
Median Duration of Response (DR)
Up to 2 years
Percentage of tumor shrinkage
Up to 2 years

Dose Escalation (Closed to Enrollment)EXPERIMENTALPatients will continue to receive osimertinib 80 mg PO daily as part of standard of care therapy during screening and study treatments. Alisertib will be administered to eligible patients in combination with osimertinib at doses ranging from 20 mg to 50 mg PO twice daily on days 1-3, 8-10, and 15-17 of a 28-day cycle. The starting alisertib dose will be 30 mg twice daily (dose level 1). All patients at a given dose level must complete the DLT period before any additional cohorts can be opened.
Dose Expansion: Cohort AEXPERIMENTALStage IV EGFR-mutant NSCLC currently receiving and progressing on osimertinib who have received no more than one additional line of systemic cancer therapy other than osimertinib (e.g., chemotherapy +/- immunotherapy, amivantamab +/- Lazertinib) for metastatic disease. Patients may receive alisertib therapy until lack of clinical benefit or intolerable toxicity.
Dose Expansion: Cohort BEXPERIMENTALStage IV EGFR-mutant NSCLC patients who are currently receiving first line osimertinib treatment and have received at least 3 months, but no more than 6 months, of osimertinib with a best response of PR or SD. Patients may receive alisertib therapy until lack of clinical benefit or intolerable toxicity.
Dose Expansion: Cohort CEXPERIMENTALStage IV EGFR-mutant NSCLC patients with no known tumor non-synonymous TP53 genomic alteration who are currently receiving first line osimertinib treatment and have received at least 3 months, but no more than 6 months, of osimertinib with a best response of PR or SD. Patients may receive alisertib therapy until lack of clinical benefit or intolerable toxicity.
Interventions
NameTypeDescription
OsimertinibDRUGOsimertinib is a medication used to treat non-small-cell lung carcinomas with a specific mutation. It is a third-generation epidermal growth factor receptor tyrosine kinase inhibitor. Patients will be receiving full dose osimertinib (80 mg PO daily) as part of the patient's current standard of care.
AlisertibDRUGAlisertib is an orally available selective aurora A kinase inhibitor. Alisertib will be administered to eligible patients in combination with osimertinib at doses ranging from 20 mg to 50 mg PO twice daily on days 1-3, 8-10, and 15-17 of a 28-day cycle. The starting alisertib dose for Cohort 1 will be 30 mg twice daily (dose level 1).
