Neoadjuvant Sacituzumab Govitecan Plus Pembrolizumab in Resectable Non-Small Cell Lung Cancer
Study Details
Study Description
Brief Summary
The combination of neoadjuvant immunotherapy plus chemotherapy has recently been shown to improve survival outcome compared to chemotherapy alone and was recently approved for resectable non-small cell lung cancer (NSCLC). Despite so, recurrence risk of NSCLC after surgical resection remains high. Sacituzumab govitecan, a novel antibody drug conjugate, was demonstrated to be clinically active in metastatic NSCLC. This study aims to study the clinical efficacy of sacituzumab govitecan plus immunotherapy in resectable NSCLC. This is a open-label, single arm, multicentre, phase II study. Patients with EGFR/ALK negative, stage II-III (AJCC 8th edition), resectable NSCLC are eligible and will receive 4 cycles of neoadjuvant pembrolizumab plus sacituzumab govitecan, followed by surgical resection of tumour, and then 13 cycles of maintenance pembrolizumab.

|---|---|
| Experimental: Sacituzumab Govitecan and Pembrolizumab Neoadjuvant treatment with pembrolizumab and sacituzumab govitecan is given for a total for 4 cycles. Pembrolizumab is administered first on day 1 every cycle. Sacituzumab govitecan is administered second on day 1 and 8 every cycle. The next cycle should start a minimum 14 days after the Day 8 dose. Surgery is to be performed within 4-8 weeks after day 1 of last cycle of neoadjuvant pembrolizumab/SG. Postoperative radiotherapy is recommended for patients with R1/R2 resection. Maintenance treatment with pembrolizumab alone is given for a total for 13 cycles. This is to be started within 4-8 weeks after surgery or within 4 weeks after postoperative radiotherapy. |

Outcome Measures
Primary Outcome Measures
- Pathological complete response (pCR) rate in the intention-to-treat population [2 years]
Secondary Outcome Measures
- Resection rate after neoadjuvant SG and pembrolizumab combination: proportion of patients who undergo surgery with curative intent [2 years]
- pCR rates in patients who undergo surgery [2 years]
- Major pathological response (MPR) rate in the ITT population and in patients who undergo surgery: MPR is defined as less than 10% viable tumor cells in resected primary tumour specimen [2 years]
- Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 while on neoadjuvant SG and pembrolizumab combination [2 years]
- Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 while on adjuvant pembrolizumab [2 years]
- Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 first 30 days after surgery [2 years]
- Objective response rate (ORR): rate of partial and complete response on CT scans according to RECIST criteria ver 1.1 [2 years]
- Overall Survival [2 years]
- 12 month and 24 month event-free survival (EFS) rate [2 years]
- Patient reported quality of life (QOL), as measured by EQ-5D-3L during study treatment. [2 years]
For the descriptive system of EQ-5D-3L, three levels of problems are described in each dimension. For the Visual Analogue Scale (VAS), the overall health assessment of the respondent is captured, ranging from 0 (worst health imaginable) to 100 (best health imaginable)
