Tumor T-Cell fraction in patients with pathologic complete response (pCR) versus residual tumor at the time of definitive surgery (approximately 6–8 weeks from baseline). Measurements were made in primary melanoma tumor biopsies (Primary), pre-treatment metastatic melanoma biopsies (Pre Tx Met) and post-treatment metastatic melanoma biopsies (Post Tx Met; approximately 6–8 weeks from baseline)
