A Safety, Tolerability and Efficacy Study of NC410 Plus Pembrolizumab in Participants with Advanced Unresectable or Metastatic Solid Tumors

This is an open-label, non-randomized, Phase 1b/2 study to determine the safety and tolerability of NC410 when combined with a standard dose of pembrolizumab. This study will also assess the clinical benefit of combination therapy in participants with advanced unresectable and/or metastatic ICI refractory solid tumors OR ICI naïve MSS/MSI-low solid tumors

Adjuvant PD-1 Blockade for High-risk Stage-II DMMR/MSI-H Colorectal Cancer

This open-label phase III trial investigates the efficacy of two cycles of PD-1 blockade (Tislelizumab) as adjuvant therapy to see how it works compared with standard of care (SOC) in treating patients with stage II dMMR/MSI-H colorectal cancer. The rational of giving PD-1 blockade as adjuvant therapy is based on the fact that tumor recurrence is extremely low among patients receiving neoadjuvant immunotherapy, which suggests that PD-1 blockade may likely improve patients' long-term survival. As for the short course (two cycles), we have the following considerations: firstly, the NICHE-2 trial, which adopted a two-cycle regimen, reported no recurrences during follow-up, suggesting that short-course anti-PD-1 therapy may be sufficient to improve the survival of patients with localized dMMR/MSI-H colorectal cancer. Secondly, the potential benefits of PD-1 blockade should be balanced against its toxicities, because patients with stage-II dMMR colorectal cancer generally have a good prognosis. Two cycles of PD-1 blockade have been shown to have a good safety profile, with low incidence of grade 3-4 and immune-related adverse events.

PD-1 Inhibitors Combined With VEGF Inhibitors for Locally Advanced dMMR/MSI-H Colorectal Cancer

In this open-label phase II study, patients will be scheduled for neoadjuvant treatment with PD-1 inhibitors (Camrelizumab) plus VEGF inhibitor (Apatinib) for dMMR/MSI-H colorectal cancer staged as locally advanced (cT3-4N+/-M0 for rectal cancer, cT4 or cT3 with extramural extension ≥5mm for colon cancer). Radiological evaluation will be preformed after 4 cycles of treatment. Patients (either with colon or rectal cancer) who achieve complete clinical response will be offered the choice of Watch \& Wait.
