You may qualify if…

For inclusion in the study patients must fulfill all of the following criteria:
Histologically confirmed first diagnosis of ES-SCLC according to the Veterans Administration Lung Study Group (VALG) Staging System for SCLC1 (disease extension that cannot be treated within one radiation field).
Oligometastatic disease defined as follows:
Primary tumor with or without mediastinal or supraclavicular lymph node metastases (counts as one lesion if it can be treated within one radiation field).
Up to four distant tumor lesions/metastases that can be treated with stereotactic radiotherapy (stereotactic radiotherapy of lung metastases in addition to radiochemotherapy of primary tumor should previously be discussed with the principal investigator).
No cytologically confirmed malignant pleural effusion (in case of suspected malignant pleural effusion in imaging, pleurocentesis for cytological assessment is required).
Stable disease (SD) or partial response (PR) according to RECIST 1.1 criteria after previous treatment with two cycles of platinum/etoposide/durvalumab.
Adequate lung function defined as forced expiratory volume in the first second (FEV1) ≥1.3 liter in spirometry.
Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Written informed consent including European Union Data Privacy Directive obtained from the patient prior to performing any protocol-related procedures, including screening evaluations.
Age > 18 years at time of study entry.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Body weight >30 kg.
Adequate normal organ and marrow function as defined below:
Hemoglobin ≥9.0 g/dL
White Blood Cells (WBC) ≥ 3,000 per mm3
Platelet count >100,000 per mm3
Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician.
AST (SGOT)/ALT (SGPT) ≤2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be ≤5x ULN
Calculated creatinine CL>40 mL/min by the Cockcroft-Gault formula
Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow-up.
Must have a life expectancy of at least 12 weeks.

You may not qualify if…

Patients should not enter the study if any of the following exclusion criteria are fulfilled:
Participation in another clinical study with an investigational product during the last 4 weeks.
Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study.
Prior systemic anticancer therapy (chemotherapy, immunotherapy, targeted therapy), apart from two cycles of etoposide/platinum + durvalumab (prior chemotherapy/ immunotherapy/ targeted therapy for other malignancy treated with curative intent ≥5 years ago is no exclusion criterion).
Any unresolved toxicity NCI CTCAE Grade ≥2 from previous chemo-immunotherapy (2 cycles of platinum/etoposide + durvalumab) with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria
Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.
Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable.
Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drug.
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 study physician
Patients with celiac disease controlled by diet alone
Uncontrolled intercurrent illness, including but not limited to, ongoing or active symptomatic infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, QTcF (QT interval on ECG corrected using the Frederica's formula) >470 ms, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent.
History of another primary malignancy except for
Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of IP and of low potential risk for recurrence
Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
Adequately treated carcinoma in situ without evidence of disease
History of leptomeningeal carcinomatosis.
History of active primary immunodeficiency.
Known active hepatitis infection, positive hepatitis C virus (HCV) antibody, hepatitis B virus (HBV) surface antigen (HBsAg) or HBV core antibody (anti-HBc), at screening. Participants with a past or resolved HBV infection (defined as the presence of anti HBc and absence of HBsAg) are eligible. Participants positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
