ClinConnect Summary

The DURVALUNG study is a clinical trial aimed at exploring whether a medication called durvalumab can help frail patients with limited small cell lung cancer (SCLC) after they have received chemotherapy and radiation treatment. This trial is specifically for patients who are considered frail, meaning they may be older or have other health issues that make standard treatments difficult. To be eligible, participants must have a confirmed diagnosis of limited small cell lung cancer, not have received prior treatment for this cancer, and have completed a certain chemotherapy and radiation regimen. Patients also need to show that their cancer hasn't worsened after treatment to qualify for the study.

If selected, participants will be randomly assigned to either receive durvalumab every four weeks or to be monitored closely without additional treatment. The goal is to see if durvalumab can help control the cancer better than just monitoring. Throughout the trial, patients will have regular check-ups and scans to assess their health and the effectiveness of the treatment. It's important to note that this study is currently recruiting participants, and anyone interested should discuss their eligibility with their healthcare provider.

• • 13. Patient must be willing and able to comply with the protocol for the duration of the trial including undergoing treatment and scheduled visits, and examinations including follow-up.
• Criteria for Inclusion:
• • 1. Patient must have signed a second written informed consent form prior to inclusion and to any specific trial procedure.
• 2. Patients must have completed concomitant or sequential thoracic CRT by IMRT:
• • Patients that received concomitant or sequential thoracic CRT must have received at least 60 Gy (one-daily fraction of 1.8-2 Gy) or 45 Gy twice daily (1.5 Gy per fraction) combined with cisplatin-etoposide regimen or with carboplatin AUC5 to AUC6 etoposide regimen.
• • 3. Confirmation of disease control (SD, CR or PR) at radiological assessment with contrast enhanced thorax and upper abdomen CT-scan or PET-CT and contrast enhanced brain CT-scan or MRI after the thoracic CRT according to RECIST v1.1.
• • 4. Use of brain MRI in case of PCI avoidance is mandatory. PCI has to be prescribed according to the investigator's choice and the local recommendations.
• • 5. Body weight \>30 kg
• 6. Patients must belong to one of these groups at the screening visit after the thoracic CRT :
• • ECOG PS 2.
• • ECOG PS 0-1 and older than 70.
• • ECOG PS 0-1 and who did not receive a concomitant thoracic CRT because of comorbidities (radiotherapy beginning before D1C3 of chemotherapy).
