Condition or disease Intervention/treatment Phase
Non-Small Cell Lung Cancer With Mutation in Epidermal Growth Factor Receptor (Disorder) Drug: Ipilimumab Drug: Osimertinib Phase 1

Detailed Description:
The primary objective is to assess the short and long term tolerability of ipilimumab in combination with osimertinib. The secondary objective is to assess efficacy of osimertinib in combination with ipilimumab. Ipilimumab will be given for a total of four doses and osimertinib will be given until treatment discontinuation criteria is met. Ipilimumab at the assigned dose level every 3 weeks for four doses in combination with once daily osimertinib.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 26 participants
Intervention Model: Single Group Assignment
Intervention Model Description:

This is a Phase 1b, open label study of osimertinib in combination with ipilimumab in eligible adult patients with locally advanced or metastatic EGFR mutated non-small cell lung cancer. The study will focus on the safety and long term tolerability of the combination.

The study will begin with a safety lead-in evaluation consisting of a cohort of six patients. Once safety has been established, the trial will open enrollment to the expansion cohort. The expansion cohort will enroll an additional 14 patients at the same doses evaluated during the safety lead-in.

Arm Intervention/treatment
Experimental: Treatment: all patients
Patients entering trial should be on stable dose of osi for ≥4 weeks. Patients will self-administer osi by mouth regardless of food once daily. Doses should be taken at about the same time every day (±6hrs) and recorded on the patient dosing diary. Doses missed outside of the dosing window should not be made up but patients should be instructed to take their next dose at their regularly scheduled time. Ipi will be administered at the assigned dose level every 21 days (±3days) for a max of 4 doses. Ipi must be infused using a volumetric pump over 90min (±10min) through an IV line. Upon completion of the ipilimumab regimen, patients will continue osimertinib daily until disease progression, initiation of new anti-cancer therapy, or death by any cause.

Primary Outcome Measures :
  1. Short and Long term tolerability of ipilimumab in combination with osimertinib: Adverse Events (AEs) [ Time Frame: The safety elevation period will be from cycle one day one to cycle two day 21. First 4 cycles=21 days. Additional cycles are 28days. ]
    Adverse Events (AEs) as characterized by type, severity (as graded by National Cancer Institute Common Terminology Criteria for Adverse Events [NCI CTCAE] v5.0), timing, seriousness, and relationship to study treatment.

Secondary Outcome Measures :
  1. Efficacy of osimertinib in combination with ipilimumab: Objective response rate (ORR) [ Time Frame: Patients will remain on treatment until progression and then followed for survival for 5 years from the end of treatment visit. ]
    Objective response rate (ORR) will be assessed by the number of patients obtaining a complete response plus the number of patients obtaining a partial response divided by the total number of response evaluable subjects.

  2. Efficacy of osimertinib in combination with ipilimumab: Osimertinib progression free survival (oPFS) [ Time Frame: PFS defined as the time between initiation of osimertinib and documented progression, death, or 5 yrs. from end of treatment ]
    Osimertinib progression free survival (oPFS) will be assessed as the time from the first dose of osimertinib until documented radiographic or clinical progression or death by any cause.

  3. Efficacy of osimertinib in combination with ipilimumab: Ipilimumab progression free survival (iPFS) [ Time Frame: iPFS defined as the time between the initiation of ipilimumab and documented progression, death, or 5 yrs from end of treatment ]
    Ipilimumab progression free survival (iPFS) as assessed as the time from the first dose of ipilimumab until documented radiographic or clinical progression or death by any cause.

  4. Efficacy of osimertinib in combination with ipilimumab: Overall survival [ Time Frame: will be assessed as the time between trial initiation and death of any cause up to 5 yrs after end of treatment ]
    Overall survival will be assessed as the time from trial initiation until death by any cause.

  5. Efficacy of osimertinib in combination with ipilimumab [ Time Frame: will be assessed as the time between radiographic progression and the initiation of any alternative anti-cancer therapy up to 5 yrs. after end of treatment. ]
    Time until the initiation of alternative anti-cancer therapy as defined as the time from radiographic progression until the first dose of alternative therapy.
