Durvalumab ± Tremelimumab in Combination With Platinum Based Chemotherapy in Untreated Extensive-Stage Small Cell Lung Cancer (CASPIAN)


About the study

This is a phase III, randomized, open-label, multicenter, global study to determine the efficacy and safety of combining durvalumab ± tremelimumab with platinum based chemotherapy (EP) followed by durvalumab ± tremelimumab maintenance therapy versus EP alone as first-line treatment in patients with extensive-stage small-cell lung cancer

Who can take part

You may be eligible to participate in the study if you meet the following criteria:


  1. Histologically or cytologically documented extensive disease. Brain metastases; must be asymptomatic or treated and stable off steroids and anti-convulsants for at least 1 month prior to study treatment.
  2. Suitable to receive a platinum-based chemotherapy regimen as 1st line treatment.
  3. Life expectancy ≥12 weeks at Day 1.
  4. ECOG 0 or 1 at enrolment.
  5. No prior exposure to immune-mediated therapy excluding therapeutic anticancer vaccines.


  1. Any history of radiotherapy to the chest prior to systemic therapy or planned consolidation chest radiation therapy (except paliative care outside of the chest).
  2. Paraneoplastic syndrome of autoimmune nature, requiring systemic treatment or clinical symptomatology suggesting worsening of PNS
  3. Active infection including tuberculosis, HIV, hepatitis B anc C
