Clinical Trial Summary

This is a Phase II, open label, randomized study of durvalumab in combination with pemetrexed and carboplatin in eligible adult patients with locally advanced or metastatic non-small cell lung cancer. The study will focus on the efficacy of two alternative staggered dosing regimens.

Description:

This trial will evaluated two different schedules of concurrent chemoimmunotherapy while simultaneously measuring immune activation, immune resistance and host factors. Both arms will consist of concurrent chemoimmunotherapy with durvalumab, pemetrexed and carboplatin, but in arm 1 the chemotherapy will precede the immunotherapy by a week and in arm 2 the immunotherapy will precede the chemotherapy by a week. Staggering these therapies still allows concurrent administration while allowing some degree of temporal isolation to better understand the contributions by chemotherapy and immunotherapy in this setting. Host and laboratory factors will be measured during treatment. We hypothesize that staggered dosing of immunotherapy in combination with chemotherapy can improve clinical benefit.

Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act in the US, European Union [EU] Data Privacy Directive in the EU) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations.

Exclusion Criteria:

• ALK or EGFR non-squamous non-small cell lung cancer.

• Prior radiation therapy within 2 weeks prior to cycle one day one.

-Exception: Prior palliative radiotherapy is permitted, provided it has been completed at least 2 days prior to study enrollment and no clinically significant toxicities are expected.

• Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP.

-Note: Local surgery of isolated lesions for palliative intent is acceptable.

• History of allogenic organ transplantation.

• Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). The following are exceptions to this criterion:

• Patients with vitiligo or alopecia

• Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement

• Any chronic skin condition that does not require systemic therapy

• Patients without active disease in the last 5 years may be included but only after consultation with the principal investigator

Intervention

Drug:
• Durvalumab
Durvalumab is administered at a dose of 1500mg for patients who weigh >30 kg. If weight falls to = 30 kg, weight-based dosing at 20mg/kg will be a utilized
• Pemetrexed
Pemetrexed dosing is adjusted for kidney function. Pemetrexed is dosed at 500mg/m2 for patients with a creatinine clearance = 45 mL/min (by Cockcroft-Gault formula). If creatinine clearance is < 45 mL/min, pemetrexed is dosed at 400 mg/m2.
• Carboplatin
Carboplatin dosing is adjusted for kidney function.The total dose (in mg) of carboplatin will be calculated using the Calvert Formula utilizing a target AUC of 5 and a patient's GFR in mL/min.
