Accrual goal not met.

This trial studies the side effects of sirolimus and durvalumab and to see how well they work in treating patients with stage I-IIIA non-small cell lung cancer. Sirolimus is an oral medication that blocks the mTOR cellular pathway which may help the immune system work better. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving sirolimus before durvalumab may help the immune system get rid of cancer.

PRIMARY OBJECTIVES:

I. To evaluate the safety and tolerability of sirolimus followed by durvalumab as neoadjuvant treatment II. To evaluate the efficacy of sirolimus followed by durvalumab as neoadjuvant treatment for stage I, II, and IIIA non-small cell lung cancer (NSCLC)

SECONDARY OBJECTIVES:

I. To evaluate the efficacy of sirolimus in combination with durvalumab as neoadjuvant treatment for stage I, II, and IIIA NSCLC II. To evaluate response to sirolimus in combination with durvalumab in patients with PD-L1-positive versus (vs.) PD-L1-negative tumors III. To evaluate the association between blood mutation burden and response to sirolimus and durvalumab

EXPLORATORY OBJECTIVES:

I. To evaluate the immune-mediated effects of combination sirolimus and durvalumab II. To investigate tumor and immune microenvironment changes in tissue samples

OUTLINE:

Patients receive sirolimus orally (PO) once daily (QD) on days 1-21 in the absence of disease progression or unacceptable toxicity. Starting on day 22, patients receive durvalumab intravenously (IV) over 1 hour. Treatment with durvalumab repeats every 21 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Within a 2-3 week period after the second dose of durvalumab, but not earlier than two weeks after the administration of durvalumab, patients undergo standard of care surgery.

After completion of study treatment, patients are followed up every 3 months for 2 years.
