Brief Summary
This single-site, biomarker-enriched, randomized Phase II study will evaluate osimertinib with or without cyclosporine A (CsA) in metastatic epidermal growth factor receptor (EGFR )-mutant non-small cell lung cancer (NSCLC) \[exon 19 deletion or L858R\]. All consented, baseline circulating tumor DNA (ctDNA)-positive patients receive a 3-week osimertinib run-in; those with persistent ctDNA ("shedders") are randomized 1:1 to continue osimertinib or osimertinib+CsA. Plasma is collected approximately every 3 weeks in both arms for molecular response monitoring. The investigators plan to enroll 60 patients with approximately 40 "shedders" randomized with 20 enrolled in each arm. All patients will be treated with osimertinib daily throughout the study; the combination of osimertinib+CsA will receive CsA. Imaging will be performed as per standard of care.

Overall Survival (OS)
Up to Year 2
Study Arms (2)
Osimertinib
ACTIVE COMPARATORFollowing a 3-week osimertinib run-in; patients continue to receive osimertinib for the duration of the study. ctDNA tests will be repeated every 3 weeks.
Osimertinib + Cyclosporine A (CsA)
EXPERIMENTALFollowing a 3-week osimertinib run-in; patients receive osimertinib and CsA for the duration of the study. ctDNA tests will be repeated every 3 weeks.
Interventions
Eligibility Criteria
You may qualify if:
- Age≥18 years, able to give informed consent.
- Standard of care (SOC) biopsy-proven metastatic non-small cell lung cancer, confirmed at NYU Langone Health (NYULH)
- Somatic activating mutation in EGFR exon 19 deletion or EGFR L858R in pre-treatment tumor biopsy or cytology from pleural fluid or cfDNA as detected by SOC testing.
- Either have not started a prior EGFR TKI therapy, or may have started osimertinib within 3 weeks of confirming eligibility and enrollment criteria of measurable disease per approval of PI, with no prior chemotherapy for treatment of metastatic disease (adjuvant therapy \> 6 months prior to study start is acceptable).
- Measurable (RECIST 1.1) indicator lesion not previously irradiated, with measurable disease determined per treating investigator. If a patient has already started on osimertinib there must be available pre-osimertinib baseline tumor assessments, to be utilized for RECIST 1.1 assessment.
- ECOG performance status of 0-2
- Adequate organ function
- Willing to use highly effective contraceptive measures if of child-bearing potential or if the patient's sexual partner is a woman of child-bearing potential
You may not qualify if:
- Pregnant or lactating women
- Any radiotherapy within 1 week prior to starting treatment on protocol. The washout window only applies for patients who have not started Osimertinib. No washout window needed if the patients started on Osimertinib. They should continue on Osimertinib. If patients received radiation prior to Osimertinib, they should wait for 7 days from the last day of radiation to start Osimertinib. If patients are already on osimertinib at the time of initial consent and they happened to also have radiation prior to starting on osimertinib, they do not need a washout in order to meet eligibility criteria for the study.
- Any major surgery within 2 weeks of starting treatment on protocol. The washout window only applies for patients who have not started Osimertinib.
- Treatment with an investigational drug within five half-lives of the compound or 3 months, whichever is greater.
- Currently receiving (or unable to stop prior to receiving the first dose of study treatment) medications or herbal supplements known to be strong inducers of CYP3A4. All patients must try to avoid concomitant use of any medications, herbal supplements and/or ingestion of foods with known inducer effects on CYP3A4.
- Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses, which in the investigator's opinion makes it undesirable for the patient to participate in the trial.
- Active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Screening for chronic conditions is not required.
- Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the tablets or previous significant bowel resection that would preclude adequate absorption of Osimertinib or cyclosporine A.
- Mean resting corrected QT interval (QTcF) \> 470 msec
- Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG e.g. complete left bundle branch block, third degree heart block and second degree heart block.
- Patient with any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, electrolyte abnormalities (including: Serum/Plasma potassium \<LLN, Serum/Plasma Magnesium \<LLN; Serum/Plasma Calcium \<LLN), congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age in first degree relatives or any concomitant medication known to prolong the QT interval and cause Torsades de Pointes. If concomitant medication can not be discontinued, please notify and confirm with MSK PI prior to enrollment.
- Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease.
- History of hypersensitivity to active or inactive excipients of osimertinib or drugs with a similar chemical structure or class to osimertinib.
- History of hypersensitivity to active or inactive excipients of cyclosporine A or drugs with a similar chemical structure or class to cyclosporine A.
- History of autoimmune disease (excluding Hashimoto's thyroiditis).
