SCRT Followed by AK112 in pMMR/MSS Mid-low Rectal Cancer

Primary Objectives： Evaluate the complete response rate (CR rate) and safety of short - course radiotherapy combined with ivonesimab (AK112) in patients with pMMR/MSS mid - low rectal cancer. Secondary Objectives： Evaluate treatment - related toxic reactions, the quality of life, long - term prognosis (local control \[LC\], disease - free survival \[DFS\] and overall survival \[OS\]). Patients will : Receive Radiotherapy: Pelvic IMRT or VMAT, DT 25Gy/5Fx. One week after radiotherapy, begin treatment with Ivorsimab (AK112) at a dose of 20mg/kg by intravenous drip on day 1. One cycle is 21 days, and a total of 6 cycles are to be carried out. Evaluate the curative effect after 3 cycles of treatment. Patients with progressive disease (PD) will withdraw from the study, and other treatment plans will be adjusted in a timely manner. Patients with CR/PR/SD will continue treatment for another 3 cycles. Conduct a comprehensive assessment after 6 cycles of treatment. Patients who achieve cCR can choose the watch - and - wait approach. For patients who do not achieve cCR, TME surgery is recommended. Decide whether to perform adjuvant chemotherapy based on the postoperative pathological findings.

A Phase II Randomized Trial of Neoadjuvant Ivonescimab or Penpulimab Plus Chemotherapy in Resectable NSCLC

This is a randomized, open-label, multicenter phase II study. The trial plans to enroll 164 subjects with resectable stage IIA-IIIB (N2) NSCLC. Participants will be randomized 1:1 into either the ivonescimab plus chemotherapy or penpulimab plus chemotherapy treatment arm. After 3-4 cycles of neoadjuvant therapy, surgical resection will be performed. The primary objective is to compare the pathological complete response (pCR) rate assessed by local pathologists between ivonescimab-based and penpulimab-based chemo-immunotherapy regimens in the neoadjuvant treatment of resectable NSCLC.

Ivonescimab Combined With Chemotherapy for the Treatment of Leptomeningeal Metastases Failed to EGFR-TKIs

Research objective Main purpose Exploring the real-world effectiveness of Ivonescimab combined with chemotherapy for EGFR mutant NSCLC with leptomeningeal metastasis after EGFR-TKIs resistance. Outcome measure: Real world intracranial disease-free survival time (iPFS). Secondary purpose Federation patterns: describing different treatment modes in the real world; Outcome measures: Combination chemotherapy regimen and duration of chemotherapy. Efficacy: Further explore the effectiveness of Ivonescimab combined with chemotherapy for EGFR mutant NSCLC with leptomeningeal metastasis failed with EGFR-TKI treatment; Outcome measures: Objective response rate (LM-ORR), duration of intracranial response (iDoR), overall progression free survival (PFS), overall survival (OS), improvement in neurological function, CSF response rate based on CSF cytology. Safety: Explore the safety of Ivonescimab combined with chemotherapy for NSCLC patients with leptomeningeal metastases who have failed EGFR-TKI treatment; Outcome measures: incidence of adverse events (TEAEs), laboratory test outliers, and serious adverse events (SAEs). Research endpoint Primary endpoint * iPFS (intracranial progression free survival). Secondary endpoint * Efficacy: leptomeningeal ORR (LM-ORR), intracranial duration of response (iDoR), overall progression free survival (PFS), overall survival (OS), improvement in neurological function, and CSF response rate based on CSF cytology; * Safety: Determine the incidence and severity of adverse events (AE) and serious adverse events (SAE) according to NCI-CTCAE5.0 standards; Changes in vital signs, laboratory abnormalities, and quality of life scores. Exploratory endpoint: efficacy related biomarkers
