Filter by:This is a trial of Regorafenib in combination with pembrolizumab for patients with MSI-H colorectal cancer consisting of lead-in phase examining preliminary efficacy and safety, followed by a randomized phase to further examine efficacy.
- Microsatellite instable (MSI) tumors represent almost the 15% of all sporadic colorectal cancers (CRCs). - Literature data show that this unique tumor population appears to be poorly responsive to conventional chemotherapy and conversely reveals excellent results to immunotherapy. - Our data, as demonstrated by propensity score-matched and win ratio analysis, show that there are no substantial differences between MSI and MSS tumors in early CRC stages treated with surgery alone. - On the contrary, stable tumors (MSS) did much better than MSI tumors in advanced CRC stages undergoing conventional adjuvant treatment. - Determination of status of DNA mismatch repair system is crucial in high-risk CRCs to optimize treatment.
This study is a multi-center, single-arm, open-label phase II clinical trial, aiming to observe and evaluate the perioperative treatment of tislelizumab combined with chemotherapy (CAPOX) in stage II or III colorectal cancer with MSI-H/dMMR Patient efficacy and safety.
This study is an open-label, multi-arm, parallel cohort, dose validation and expansion design. The study is modular in design, allowing evaluation of the safety, efficacy and pharmacokinetics (PK) of NUC-3373 in combination with other agents for the treatment of patients with different tumour types. Each module is designed to evaluate a different NUC-3373 combination and consists of a dose-validation phase (Phase Ib) and a dose-expansion phase (Phase II). Phase Ib of each module will determine the safety and tolerability of the combinations for further clinical evaluation in Phase II. Approximately 6-20 evaluable patients will be enrolled in the Phase Ib stage of each module to determine safety, tolerability, and preliminary efficacy of NUC-3373 in combination with other agents. Each module will then move into Phase II to enable a further assessment of safety and efficacy in approximately 20-40 patients. Module 1 will assess NUC-3373 + leucovorin (LV) in combination with pembrolizumab for the treatment of patients with advanced/metastatic solid tumours who have progressed on ≤2 prior therapies for metastatic disease, that may have included 1 prior immunotherapy-containing regimen (either monotherapy or in combination with chemotherapy) or who have not progressed but where addition of NUC-3373 + LV to standard pembrolizumab monotherapy may be appropriate (e.g., patients who could not tolerate post- immuno-oncology (IO) standard of care therapy). Module 2 will assess NUC-3373 + LV in combination with docetaxel for the treatment of patients with advanced/metastatic non-small cell lung cancer (NSCLC) or pleural mesothelioma who have progressed on, or were unable to tolerate, 1 or 2 prior lines of cytotoxic chemotherapy-containing regimens for advanced/metastatic disease. The opening of each module will be at the discretion of the Sponsor. Further modules may be added as non-clinical and clinical data become available to support additional NUC-3373 combinations and tumour types.
This is a monocentric, prospective, pilot study that will enrol 435 subjects with solid tumours that are treated with immune checkpoint inhibitor(s) (ICI) alone or in combination with chemotherapy or targeted therapy. For enrolled subjects, clinical and laboratory evaluations will be performed and reported at different time points: - Early (4-6 weeks after treatment start) - Midtime (8-11 weeks after treatment start) - Late (13-18 weeks after treatment start) - At the occurrence of immune-related adverse events (irAEs), clinical and laboratory evaluation will be performed at two principal time points: - For the 1st time of any grade 1 or 2 irAE if the subject developed it. - For the 1st time of any grade 3 or 4 irAE if the subject developed it.
This is an open-label, parallel group, non-randomized, multicenter phase II study to evaluate the efficacy of spartalizumab (cohorts 1 and 2) and tislelizumab (cohort 3) in monotherapy in patients with PD1-high-expressing tumors.
NIPISAFE is open-label, phase II study to identify a combination scheme of nivolumab and ipilimumab with a high level of clinical activity, but with a lower toxicity in MSI/dMMR metastatic colorectal cancer patients.
This is an open-label, non-randomized, multicenter, dose-escalation and expansion study in patients with selected solid tumors.
PD1 antibody is now recommended for dMMR/MSI-H metastatic colorectal cancer patients as second line. Chemoradiotherapy is standand treatment for locally advanced rectal cancer and is also recommended as an alternative choice for unresectable locally advanced colon cancer. Thus, this study will investigate the efficacy and toxicity of combination strategy using PD1 antibody and chemoradiotherapy for dMMR/MSI-H locally advnaced colorectal cancer patients.
ATRC-101-A01 is a Phase 1b, open-label dose escalation and expansion trial of ATRC-101, an engineered fully human immunoglobulin G, subclass 1 (IgG1) antibody derived from a naturally occurring human antibody. The safety, tolerability, PK, and biological activity of ATRC-101 will be characterized when administered every two weeks (Q2W) or every 3 weeks (Q3W) as a monotherapy or in combination with other anticancer agents.
