Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

1. Written informed consent
2. Patients with locally advanced or metastatic large-cell neuroendocrine carcinoma of the lung (LCNEC) without curative treatment options (patients with mixed histology are eligible if LCNEC is the predominant histology i.e. ≥50%)
3. Previously untreated with systemic therapy (note: patients relapsing after curative radio chemotherapy or adjuvant chemotherapy are eligible if relapse occurs ≥6 months after discontinuation of curative treatment)
4. Planned treatment with Carboplatin or Cisplatin and Etoposide (SoC)
5. ECOG performance status: 0-2
6. age ≥18 years
7. measurable disease according to RECIST v1.1

8. adequate organ function defined as:

   1. ALAT/ASAT ≤2.5x ULN or ≤3.5x ULN in case of liver metastases
   2. Bilirubin ≤1.5x ULN or ≤2.5x ULN in case of liver metastases
   3. Creatinine ≤1.5x ULN or Creatinine clearance according to Cockroft-Gault >60 ml/min
   4. Neutrophils ≥1 Gpt/l, Platelets >50 Gpt/l unless caused by bone marrow carcinosis

Exclusion Criteria:

1. Symptomatic brain metastases (patients with asymptomatic brain metastases are allowed provided they are stable without steroid treatment for at least 3 weeks)
2. Severe autoimmune disease (patients with endocrine autoimmune disorders are allowed as long as they are on stable substitution treatment)
3. Severe uncontrolled infection
4. Prior treatment with either Atezolizumab or other immune checkpoint inhibitor
5. Any prior treatment for metastatic disease

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Atezolizumab/Platinum/Etoposide; Atezolizumab/Platinum/Etoposide Platinum will be cisplatin or carboplatin at the investigators discretion.	Drug: Atezolizumab; Atezolizumab (IMP) will be added to Platinum/Etoposide (Standard-of-Care). Four cycles of combined immunochemotherapy 3qw will be followed by maintenance with atezolizumab monotherapy until progression.
