study of treatment with sacituzumab and zimberelimab for patients with lung cancer confined to the chest and previously operated on who were not disease-free.

Conditions: Lung Diseases; Carcinoma, Non-Small-Cell Lung; Resectable Lung Non-Small Cell Carcinoma

Summary: open-label, phase iii, randomized, stratified (pdl1- vs pdl1+), 3 arms, multicenter clinical trial. 129 resected patients (43 per arm) with stage from ib to iiia and iiib (n2) non-small cell lung cancer that do not achieve pathologic complete response (pcr) after neoadjuvant treatment. this clinical trial has 3 arms of treatment. arm 1: observation 10 months, arm 2: treatment with immunotherapy (zimberelimab) for 13 cycles and arm 3: treatment with sacituzumab govitecan and zimberelimab for 8 cycles and zimberelimab monotherapy for 5 cycles. the primary objective is to evaluate the disease-free survival (dfs): defined as the length of time from randomization to the earliest event defined as disease recurrence, any new lung cancer (even in the opposite lung), or death from any cause at any known point in time. patient accrual is expected to be completed within 2 years, treatment is planned to extend during 1 years and the patients will be followed up for 2 years. the study will end once survival follow-up has concluded.

this is an open-label, phase iii, randomized, stratified (pdl1- vs pdl1+), 3 arms, multicenter clinical trial. patients stage ib to iiia-iiib (t3n2) after surgical resection if they did not achieve a pathological com-plete response (pcr) will be randomized 1:1:1 to: * arm 1: observational arm for 10 months * arm 2: immunotherapy (zimberelimab) treatment for 13 cycles, q3w * arm 3: sacituzumab govitecan + zimberelimab q3w for 8 cycles + zimberelimab q3w for 5 cycles. patients will receive 8 cycles of the combination and 5 cycles of zimberelimab monotherapy. the primary objective is to evaluate the disease-free survival (dfs): defined as the length of time from randomization to the earliest event defined as disease recurrence, any new lung cancer (even in the opposite lung), or death from any cause at any known point in time. disease free survival (dfs): the time from random assignment to cancer recurrence or death from any cause. secondary objectives: * overall survival (os): at 12, 24 and 36 months after the start of adjuvant treatment * safety and tolerability of the combination of sacituzumab govitecan + zimberelimab according to ctcae v5.0. exploratory objectives - to evaluate whether there is a significant association between change in levels of ctdna between baseline and after adjuvant treatment and os and dfs. the total trial duration will be 7 years approximately. approval-start up: 4-6 months. patient accrual is expected to be completed within 2 years. one year of treatment and 3 years of follow up, and close-out: 4-6 months. the study will end once survival follow-up has concluded

Eligibility criteria:
inclusion criteria: * 1. patients diagnosed of primary non-small cell lung cancer, histologically confirmed. * 2. patients should be classified postoperatively in stage ib, iia, iib, iiia or iiib (n2) according to pathological criteria (ptnm) and according to 8th version of the international association for the study of lung cancer staging manual in thoracic oncology * 3. complete surgical resection (r0) of the primary nsclc is also essential. surgeons are strongly advised to dissect or obtain samples of all accessible lymph node levels, as established in the european society of thoracic surgeons guide. consequently, at the end of the surgical intervention it is recommended to have obtained samples of a minimum of 3 specific mediastinal ganglionic lobe stations (n2), one of which should include station 7, and at least one n1 station * 4. the surgical intervention may consist of a lobectomy, sleeve resection, bilobectomy or pneumonectomy, as determined by the responsible surgeon based on intraoperative findings. patients who have had only segmentectomies or wedge resections are not considered eligible for participation in this study except if r0 resection can be confirmed. * 5. only patients that do not achieve pathological complete response (pcr) seen in the surgical piece after neoadjuvant therapy are eligible. * 6. preoperative (neoadjuvant) use of
