Filter by:This is a First-in-Human Phase IA/IB/II open label dose escalation study of intravenous (IV) administration of ONC-392, a humanized anti-CTLA4 IgG1 monoclonal antibody, as single agent and in combination with pembrolizumab in participants with advanced or metastatic solid tumors and non-small cell lung cancers.
This is a two-arm, randomized, double-blinded, multicenter phase III clinical study to evaluate the efficacy of HLX10 combined with chemotherapy versus placebo combined with chemotherapy for neoadjuvant/adjuvant treatment of gastric cancer. Subjects will be randomized to the following two arms at 1: 1 ratio: - Arm A (HLX10 arm): HLX10 combined with chemotherapy will be adopted in the neoadjuvant treatment phase, and HLX10 monotherapy will be administered in the adjuvant treatment phase; - Arm B (control arm): Placebo combined with chemotherapy will be given in the neoadjuvant treatment phase, and chemotherapy alone will be administered during the adjuvant treatment phase. Chemotherapy regimen SOX (oxaliplatin + tegafor gimeracil oteracil potassium (S-1)) will be used in the neoadjuvant treatment phase in Arm A and B, and in the adjuvant treatment phase in Arm B. After randomization, subjects will receive a total of 3 cycles of neoadjuvant treatment with the mentioned treatment regimen.Surgery will be performed within 3-6 weeks after the last cycle of neoadjuvant treatment.All subjects who have completed the surgery will be unblinded after surgery, and adjuvant treatment will be started 3 to 12 weeks after surgery. Subjects randomized to Arm A (HLX10 arm) will continue to receive HLX10 monotherapy for up to 17 cycles (12 months).Subjects in Arm B after surgery (control arm) will continue to use chemotherapy alone (oxaliplatin + S-1) for 5 cycles.
This is an explorative, phase I clinical trial. The aim of this study is to establish the safety and efficacy of electrochemotherapy for non-curable gastric cancer.
This study is intended to evaluate efficacy and safety of EGFR monoclonal antibody (Cetuximab/Nimotuzumab) in combination with a chemotherapy in gastric cancer patients with EGFR amplification.
This is a Phase II, open-label, single dose level study of PRL3-ZUMAB monotherapy in patients with advanced solid tumours that have failed standard therapy. Approximately 30 patients will be recruited with ~10 gastric cancers and ~10 hepatocellular carcinomas. Patients who have received at least 1 dose of PRL3-ZUMAB will be evaluable for toxicity and efficacy. PRL3-ZUMAB will be given IV every 2 weeks for up to 12 infusions in the absence of unmanageable toxicities or disease progression. Patients who are benefitting from the treatment may continue on PRL3-ZUMAB beyond 12 infusions with the agreement of the study drug provider. PRL3-ZUMAB at the RP2D in tumour types enriched for known PRL-3 expression for efficacy and tolerability will be evaluated. There will also be in depth molecular profiling of tissues in patients who have an objective response or prolonged disease stabilization to identify predictive/selection biomarkers as well as evaluation of the oncogenic signaling modulation and immunomodulation by PRL3-ZUMAB and its potential for future combination with other targeted therapies or immunotherapy.
The main purpose of this study is to evaluate the impact of omentectomy for advanced gastric cancer on patient survival.
To assess if PD-L1 expression can be upregulated in peritoneal metastases from gastric cancer after the administration of HIPEC with greater frequency compared to systemic chemotherapy alone
Gastric cancer ranks as the fifth most common and the third most common cause of cancer deaths in the world. In spite of the progresses made in the diagnosis and treatment of gastric cancer in the past decades, the prognosis is still unsatisfied mainly due to recurrence and distant metastasis. Surgical treatment is the first choice for the treatment of early gastric cancer, but it is prone to recurrence and metastasis after surgery. There are relatively few chemotherapy drugs for gastric cancer. Studies have shown that about 13% of gastric cancers have HER2 gene amplification, and there are no other known driver gene other than HER-2. At present, the targeted therapeutic drugs approved for gastric cancer in China are only trastuzumab and apatinib. Immune checkpoint inhibitors, including PD-1 inhibitors, PD-L1 inhibitors and CTLA-4 inhibitors, have achieved significant therapeutic effects in a variety of tumors and are expected to alter the current state of treatment of tumors. In gastric cancer, the KEYNOTE-012 study demonstated the efficacy of Pembrolizumab in patients with PD-L1 positive advanced gastric cancer. The study showed that 53% of patients had tumor retraction, and 22% achieved partial imaging remission with a median duration of 40 weeks. At the same time, Pembrolizumab is also less toxic than standard second-line chemotherapy. However, Are the Immune checkpoint inhibitors should be used as single-drug or in combination with chemotherapy? Are the Immune checkpoint inhibitors should be used in the first-line or in the back-line? And which is the best combination therapy? For these issues, there is no conclusion yet. This observational study included all patients with gastric cancer who used Immune checkpoint inhibitors in clinical practice, regardless of treatment lines and combination with different chemotherapy. Through follow-up observations, the aim of this study is to analyze the efficacy of Immune checkpoint inhibitors for gastric cancer in the real world, and to explore the differences in the efficacy of Immune checkpoint inhibitors in different stages of treatment, as well as the efficacy of different chemotherapy combinations, so as to provide clinical evidence for the use of immunotherapy for advanced gastric cancer.
This is a non-randomized multicenter phase 1b clinical trial of the safety and pharmacokinetics, as well as the preliminary efficacy of monotherapy with alofanib, an allosteric fibroblast growth factor receptor 2 inhibitor, in patients with advanced gastric cancer who have exhausted the resource of standard therapy.
Cohort 1 [CLOSED] Study treatment involves two segments: (1) Induction Immunotherapy segment with pembrolizumab monotherapy every 3 weeks until irRECIST PD and (2) Combination Therapy segment. Nab-paclitaxel may be utilized in place of paclitaxel at investigator's discretion for subjects with paclitaxel reactions. Cohort 2 Patients are randomized to Arm A or B. Treatment in both arms includes pembrolizumab + RAM + paclitaxel.
