Brief Summary
Metastatic non-small cell lung cancer is often treated with a combination of chemotherapy and immunotherapy. In patients over the age of 70, some are already in poor health and frail, requiring assistance with daily activities, for example. Older and/or frail individuals often do not tolerate standard-dose chemotherapy well, and their risk of side effects is higher than that of younger patients. For this reason, the SAKK 18/24 study is investigating how effective and safe chemotherapy is in patients over 70 years of age when the chemotherapy drugs are administered at lower doses than usual. The aim of the study is to find a potentially effective and well-tolerated treatment for older people with metastatic non-small cell lung cancer.

Outcome Measures
Primary Outcomes (1)
Progression-free survival (PFS)
PFS is defined as time from randomization to confirmed tumor progression according to RECIST 1.1 or death due to any cause. Patients not experiencing an event will be censored at their last tumor assessment before starting a new anti-cancer treatment line (if any).
From the date of randomization until the date of confirmed tumor progression according to RECIST 1.1 or death from any cause, assessed up to 1 year after end of treatment.
Secondary Outcomes (2)
Overall survival (OS)
From the date of randomization until the date of death from any cause, assessed up to 1 year after end of treatment.
Objective response rate (ORR)
From the date of randomization until the end of treatment, estimated up to 1 year after randomization.
Study Arms (2)
Experimental arm
EXPERIMENTALNon-squamous histology: * carboplatin IV AUC 3 day 1 * pemetrexed IV 300 mg/m2 day 1 * cemiplimab IV 350 mg, day 1 Every 3 weeks, for 4 cycles, followed by maintenance treatment with cemiplimab with or without pemetrexed (at same dose and interval as above). Squamous histology: * carboplatin IV AUC 1.5 day 1, d8 * gemcitabine IV 600 mg/m2 day 1, d8 * cemiplimab IV 350 mg, day 1 Every 3 weeks, for 4 cycles, followed by maintenance treatment with cemiplimab (350 mg q3w) Any histology: * carboplatin IV AUC 1.5 day 1, d8 * paclitaxel IV 50 mg/m2 day 1, d8 * cemiplimab IV 350 mg, day 1 Every 3 weeks, for 4 cycles, followed by maintenance treatment with cemiplimab (350 mg q3w)
Comparator arm
ACTIVE COMPARATORcemiplimab IV 350 mg, day 1 Every 3 weeks (max. 2 years)
Interventions
pemetrexed IV 300 mg/m2 day 1 gemcitabine IV 600 mg/m2 day 1, d8
Eligibility Criteria
You may qualify if:
- Informed Consent as documented by signature
- Histologically or cytologically confirmed NSCLC. Mixed histology with small-cell component is not allowed.
- Metastatic or advanced or recurrent NSCLC without a curative-intent treatment option (surgery or chemo-radiotherapy).
- PD-L1 \<50% by local testing (SP 142 excluded)
- ≥70 years
- ECOG 0-2
- G8 screening score of ≤14 and/or ineligible for full-dose chemotherapy, defined as doses of carboplatin AUC 5, pemetrexed 500 mg/m2, paclitaxel 175 mg/m2, gemcitabine 1200 mg/m2 (as per Investigator)
- Life expectancy ≥6 months
- Patients with a prior malignancy (except NSCLC, see EC 7.2.2 and 7.2.3) and treated with curative intent are eligible if all treatment of that malignancy was completed at least 2 years before registration and the patient has no evidence of disease at registration. Less than 2 years is acceptable for malignancies with low risk of recurrence and/or no late recurrence, after consultation with CI.
- Patients with asymptomatic untreated or symptomatic treated CNS metastases are eligible if corticosteroid dose \<10 mg prednisolone equivalent/day for at least 7 days
- Patients must be suitable to receive reduced-dose carboplatin-doublet chemotherapy in combination with immunotherapy including adequate bone marrow, renal and hepatic function as follows:
- Hemoglobin ≥90 g/L, neutrophils ≥1.5 G/L, Thrombocytes ≥100G/L
- Creatinine clearance (Cockroft-Gault) ≥30 mL/min
- ASAT/ALAT ≤2xULN, Bilirubin ≤1.5xULN (≤3xULN for patients with Gilbert's disease),
- Men agree not to donate sperm or father a child during trial treatment and until 6 months after the last dose of trial treatment
You may not qualify if:
- Actionable genomic alteration for 1L treatment (EGFR, ALK, ROS1, RET, NTRK, MET Exon14 skipping). Testing is required for any NSQ-NSCLC or patients with SCC and a smoking history of ≤10py.
- Prior systemic treatment for metastatic NSCLC.
- Prior chemotherapy and/or immunotherapy in curative-intent treatment for locally advanced NSCLC in the past 6 months.
- Oligometastatic treatment concept with induction systemic therapy and planned LAT to all lesions.
- High tumor burden with a risk of rapid critical progression, as judged by the Investigator. Careful patient selection is important in order to prevent that patients in the comparator arm are not eligible for receiving add-on reduced-dose chemotherapy anymore if primary progression occurs (e.g., pericardial infiltration, high liver metastasis load etc).
- Active, treatment-requiring auto-immune disease in the past 2 years other than vitiligo, alopecia, hypothyroidism, type 1 diabetes or diet-controlled celiac disease.
- History of pneumonitis in the past 5 years.
- Systemic corticosteroid treatment ≥10 mg/day of prednisolone-equivalent or any other systemic immunosuppressive medication within 7 days prior to first dose of study intervention (except as needed for chemotherapy premedication or for physiologic corticosteroid replacement)
- Any infection requiring hospitalization or treatment with IV anti-infectives within 2 weeks of first dose of study medication
- Uncontrolled infection with HIV, hepatitis B or hepatitis C infection
- Receipt of a live vaccine within 4 weeks of start of study medication
- Receipt of COVID-19 vaccination within 1 week of planned start of study medication or for which the planned COVID-19 vaccinations would not be completed 1 week prior to start of study medication
- Organ transplant
