Anti-PD-1 and CapOx for the First-line Treatment of dMMR Esophagogastric Cancer (AuspiCiOus)

This is a multi-center, open label, proof-of-principle study for patients with previously untreated metastatic or locally advanced esophagogastric cancer. Patients are sequentially treated with standard of care capecitabine and oxaliplatin, and retifanlimab. Patients are treated with 2 cycles of CapOx (1 cycle is 3 weeks) and sequentially with 4-weekly cycles of retifanlimab up to 2 years. The investigators will include 25 patients in this study. Biopsies, blood and faeces will be collected during treatment for assessment of infiltrating immune cells and IFNy expression, as well as for other translational research purposes. CT scans are made for evaluation of tumor response before and after chemotherapy, and after 2-3 cycles of immunotherapy.

2 Versus 6 Hour Oxaliplatin Infusions in Patients with Gastrointestinal Cancers

PRIMARY OBJECTIVE: I. To determine the effect of 2 versus 6-hour oxaliplatin infusion time on the difference in severity of sensory neuropathy as measured by patient reported outcome (PRO) scores on the European Organization for Research and Treatment of Cancer (EORTC) chemotherapy-induced peripheral neuropathy (CIPN-20) scale at the initiation of cycle 4. SECONDARY OBJECTIVES: I. Pharmacokinetic parameters of maximum concentration (Cmax), area under the curve (AUC), time of maximum concentration (tmax), clearance, and half life (t1/2) of platinum ultra-filtrate. II. CIPN-20 sensory score changes over the duration of therapy as measured by a cumulative area-under-the curve score. III. Clinical outcomes including duration of therapy, oxaliplatin dose reductions, delays in therapy, and overall dose intensity and delivery of oxaliplatin. IV. Relationship between oxaliplatin Cmax, patient-reported acute neurotoxicity, and chronic neurotoxicity by CIPN-20 scores. OUTLINE: Patients are randomized to 1 of 2 groups. 2-hour infusion group: Patients receive oxaliplatin intravenously (IV) and leucovorin IV over 2 hours on day 1. Patients also receive a lower dose of fluorouracil IV over 2-4 minutes followed by a higher dose IV continuous over 4-6 hours on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. 6-hour infusion group: Patients receive oxaliplatin IV over 6 hours on day 1. Patients also receive leucovorin and fluorouracil as in the 2-hour infusion group. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 1, 3, 6, 12, and 18 months.

A Study to Evaluate the Optimization of the Cytokine Release Syndrome Profile for Glofitamab in Combination With Gemcitabine Plus Oxaliplatin in Participants With Relapsed/Refractory Diffuse Large B-Cell Lymphoma

CapeOX Combined With Bevacizumab Plus Anti-PD1 Antibody as Neoadjuvant Therapy for Locally Recurrent Colorectal Cancer

Perioperative Treatment of High-risk Resectable CCA with HAIC Plus A+T: Neobrave CCA

Biliary tract cancers (BTC), mainly including cholangiocarcinoma and gallbladder cancer, are highly heterogeneous, aggressive malignant tumors with poor prognoses, exhibiting a 5-year survival rate of less than 5%. About 70% of patients are diagnosed at an advanced localized stage or have distant metastases, losing the chance for surgical cure; among resectable BTC patients, surgery alone has historically been the standard treatment, but even with curative surgery, the cure rates remain relatively low, with most patients relapsing in the short term and a 5-year survival rate of approximately 50% or lower. The efficacy of neoadjuvant and adjuvant therapies has been validated in other types of cancers and is recommended as standard treatment in various guidelines. In BTC, numerous exploratory studies on neoadjuvant treatment have been conducted, yielding varying results, but overall indicating that neoadjuvant therapy can enhance R0 resection rates and prolong survival in certain patients, particularly those with borderline resectable and locally advanced BTC. With advances in drug research and improvements in treatment protocols, a series of emerging treatment options like combination therapy, targeted therapy, and immunotherapy have significantly improved treatment outcomes, providing favorable conditions for perioperative treatment of BTC. Currently, there remains a lack of large prospective randomized controlled phase III clinical trials confirming the exact benefits of neoadjuvant and adjuvant therapies for BTC. The SWOG 1815 study is a randomized, open-label phase III trial comparing GAP with Gemcitabine/Cisplatin (GC) in patients with advanced BTC. In exploratory subgroup analyses, GAP improved mOS compared to GC in patients with locally advanced disease (19.2 vs. 13.7 months; HR 0.67, 95% CI 0.42-1.06, p = 0.09); the objective response rate (ORR) for locally advanced disease was 28% vs. 21% (p = 0.74). Thus, patients with locally advanced disease may benefit more from GAP treatment. In another multi-institutional, single-arm, phase II trial including 30 resectable, high-risk iCCA patients (tumor size >5 cm, multiple tumors, major vascular invasion or lymph node involvement seen on imaging), patients received a total of 4 cycles of preoperative GAP (Gemcitabine 800 mg/m2, Cisplatin 25 mg/m2, nab-Paclitaxel 100 mg/m2, administered on days 1 and 8 of a 21-day cycle) before attempting radical surgical resection. The median follow-up time for all patients was 17 months; the disease control rate was 90% (disease progression: 10%, partial response: 23%, stable disease: 67%). Therefore, the preoperative neoadjuvant therapy of Gemcitabine, Cisplatin, and nab-Paclitaxel for iCCA is feasible and safe, with no adverse effects on perioperative outcomes. With the in-depth research on immune checkpoint inhibitors, during the pre-planned interim analysis of TOPAZ-1 (NCT03875235) (data cutoff date August 11, 2021), the addition of Durvalumab significantly improved OS in patients with advanced BTC compared to the control group receiving GC chemotherapy (hazard ratio [HR], 0.80; 95% confidence interval [CI], 0.66-0.97; p = 0.021). Meanwhile, neoadjuvant D + GemCis was confirmed to result in a higher surgical resection rate among patients with locally advanced BTC, and surgical resection was associated with higher survival rates. The investigators previously explored a prospective phase II study and showed promising results of HAIC using oxaliplatin and 5-fluorouracil for perihilar cholangiocarcinoma (pCCA), with an objective response rate (ORR) of 67.6%, a mPFS of 12.2 months, and a mOS of 20.5 months. Another phase II single-arm, single-center, prospective study enrolled 32 untreated BTC patients, among which iCCA accounted for 34.4% (11/32), pCCA for 53.1% (17/32), and gallbladder cancer for 12.5% (4/32). Using HAIC combined with anti-PD-1 monoclonal antibody and bevacizumab as a first-line treatment regimen, the ORR was 84.3%, and the disease control rate (DCR) was 96.9%, with one-year PFS and OS rates of 53.8% and 80.4%, respectively. Based on this study, the investigators plan to conduct a prospective single-arm phase II clinical study to further explore the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) combined with atezolizumab and bevacizumab (Atezo/Bev) foras perioperative treatment of resectable cholangiocarcinoma with high-risk recurrence factors, while also investigating prognostic and predictive biomarkers related to efficacy to provide new evidence for the perioperative treatment of initially resectable but high-risk recurrence factor intrahepatic and perihilar cholangiocarcinoma.

Neoadjuvant Serplulimab & Bevacizumab With FOLFOX vs. FOLFOX Alone in RAS/BRAF WT, pMMR/MSS CRC Patients

In this prospective, multi-center clinical trial titled "INTENSIFY," we seek to evaluate the potential benefits of integrating Serplulimab and Bevacizumab with the standard FOLFOX chemotherapy regimen as neoadjuvant treatment for surgically resectable colorectal cancer liver metastases (CRLM). Colorectal cancer remains a leading cause of global cancer-related morbidity and mortality, with liver metastases accounting for a significant proportion. Our primary objective is to investigate whether the addition of Serplulimab, a PD-1 inhibitor, and Bevacizumab, an anti-angiogenesis agent, can improve the postoperative prognosis for patients with RAS/BRAF wild-type, pMMR/MSS CRLM. We aim to address critical questions regarding the efficacy of this combined treatment in enhancing the immune microenvironment within the liver, ultimately leading to increased T lymphocyte infiltration and improved patient outcomes. The study will involve a randomized assignment of patients to either the standard FOLFOX chemotherapy arm or the experimental arm receiving FOLFOX in combination with Serplulimab and Bevacizumab. Participants will undergo neoadjuvant treatment, surgical resection, and regular follow-up assessments to evaluate treatment response, recurrence rates, and overall survival. By comparing outcomes between the two groups, specifically assessing factors like recurrence-free survival, overall survival, and changes in the immune microenvironment, we aim to provide valuable insights into the optimization of treatment strategies for this specific subset of colorectal cancer patients.

Efficacy and Safety of Chemotherapy With XELOX (Oxaliplatin + Capecitabine) and Bevacizumab in Combination With Adebrelimab in First-line Treatment of Microsatellite Stable (MSS) Initially Unresectable Metastatic Colorectal Cancer

At present, the survival benefit of MSS mCRC patients is limited, and the general survival time is only about 3-4 months. Up to now, the standard treatment plan is FOLFOX combined with bevacizumab. AtezoTRIBE study shows that compared with FOLFOXIRI+ bevacizumab, the standard treatment plan is better than the standard treatment plan. The combination of PD-L1 monomone attillizumab extended mPFS from 11.4 months to 12.9 months, showing certain efficacy, and the combination of Attillizumab did not increase adverse reactions. Based on the above, this study aims to explore the efficacy and safety of chemotherapy with XELOX (oxaliplatin + capecitabine) regimen and bevacizumab combined with adbelizumab in first-line treatment of microsatellite stable (MSS) type of initial unresectable metastatic colorectal cancer.

Short-course Radiotherapy Followed by Fruquintinib Plus Adebrelimab and CAPOX in the Full Course Neoadjuvant Treatment of Locally Advanced Rectal Cancer: a Multicenter, Single-arm, Open-label Study

This study was a multicenter, single-arm, open-label clinical trial. The study included a screening period (within 21 days after signing the informed consent form to the first treatment), a treatment period (including total neoadjuvant and surgical treatment), and a follow-up period (including safety and survival follow-up). Total neoadjuvant therapy: - Short-course radiotherapy followed by 6 cycles of fuquinitinib combined with adbelimumab and CAPOX followed by surgical resection after 1 week of rest; - A treatment time window of ±3 days was allowed during the study treatment, but within 3 days before each treatment, in addition to the required imaging examinations, participants were required to complete laboratory tests, physical examinations (as needed), ECOG scores and other safety assessments to determine that they could still tolerate the study treatment. The safety of the subjects was continuously assessed during the study. - Total Mesorectal Excision (TME) is recommended for radical resection of rectal cancer.
