|
E.2.2 | Secondary objectives of the trial |

E.3 | Principal inclusion criteria |
1. 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). 2. 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) 3. Stable disease (SD) or partial response (PR) according to RECIST 1.1 criteria after previous treatment with two cycles of platinum/etoposide/durvalumab. 4. Adequate lung function defined as forced expiratory volume in the first second (FEV1) ≥1.3 liter in spirometry. 5. 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. 6. Age > 18 years at time of study entry. 7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 . 8. Body weight >30 kg. 9. 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: Males: Creatinine CL (mL/min) = Weight (kg) x (140 – Age) / 72 x serum creatinine (mg/dL) Females: Creatinine CL (mL/min) = Weight (kg) x (140 – Age) x 0.85 / 72 x serum creatinine (mg/dL) 10. 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. 11. Must have a life expectancy of at least 12 weeks. |

E.4 | Principal exclusion criteria |
1. Participation in another clinical study with an investigational product during the last 4 weeks 2.

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). 4.

Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions is acceptable 6.

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 8. History of allogenic organ transplantation 9. 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.) 10. 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 11. 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 12. History of leptomeningeal carcinomatosis 13. History of active primary immunodeficiency 14. 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. 15. Known to have tested positive for human immunodeficiency virus (HIV) (positive HIV 1/2 antibodies) or active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings) 16. Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. Exceptions to this are: Intranasal, inhaled, topical steroids, or local steroid injections Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent Steroids as premedication for hypersensitivity reactions 17. Receipt of live attenuated vaccine within 30 days prior to the first dose of IP. Note: Patients, if enrolled, should not receive live vaccine whilst receiving IP and up to 30 days after the last dose of IP 18. Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential who are not willing to employ effective birth control from screening to 90 days after the last dose of durvalumab monotherapy 19. Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients 20. Prior randomization or treatment in a previous durvalumab clinical study regardless of treatment arm assignment. 21. Judgment by the investigator that the patient is unsuitable to participate in the study and the patient is unlikely to comply with study procedures, restrictions and requirements 22. Known allergy or hypersensitivity to IP or any excipient |
