Alpelisib and Paclitaxel in PIK3CA-altered Gastric Cancer
Solid TumorStomach CancerAlpelisib (BYL719) is a PIK3CA-specific inhibitor, which was developed by Novartis (Basel, Switzerland). Our group conducted pre-clinical study of alpelisib in eight gastric cancer cell lines: four PIK3CA wild-type (SNU638, SNU668, SNU1, and SNU16) and four PIK3CA mutant (SNU719, AGS, SNU601, and MKN). As a result, alpelisib preferentially inhibited the growth of gastric cancer cells with PIK3CA mutations. In addition, alpelisib inhibited cell growth via G1 arrest and subsequently induces apoptosis in GC cells, and this effect is more remarkable in cells harboring PIK3CA mutations. Moreover, alpelisib in combination with paclitaxel showed synergistic cytotoxic effects and significantly increased apoptosis compared with alpelisib or paclitaxel monotherapy in GC cells. The purpose of the study is to define the maximal tolerated dose (MTD) and recommended phase II dose (RP2D) of paclitaxel and alpelisib combination therapy in patients with advanced tumors and to evaluate the efficacy of paclitaxel and AZD8186 combination therapy as a second-line therapy in patients with advanced gastric cancer with PTEN aberrations. This study is divided into Phase IB and Phase II.
A Safety Study of SEA-TGT (SGN-TGT) in Advanced Cancer
Non-small Cell Lung CancerGastric Carcinoma10 moreThis trial will look at a drug called SEA-TGT (also known as SGN-TGT) to find out whether it is safe for patients with solid tumors and lymphomas. It will study SEA-TGT to find out what its side effects are. A side effect is anything the drug does besides treating cancer. It will also study whether SEA-TGT works to treat solid tumors and lymphomas. The study will have four parts. Part A of the study will find out how much SEA-TGT should be given to patients. Part B will use the dose found in Part A to find out how safe SEA-TGT is and if it works to treat solid tumors and lymphomas. Part C will study how well SEA-TGT with sasanlimab works to treat solid tumors. Part D will study how well SEA-TGT with brentuximab vedotin works to treat classical Hodgkin lymphoma (cHL).
Study of PRRT in Metastatic, World Health Organization (WHO) Grade 1 or 2, SSTR Positive, GEP-NET...
Gastroenteropancreatic Neuroendocrine TumorThe purpose of this study is to learn about the feasibility and safety of using Peptide Receptor Radionuclide Therapy (PRRT) before and after surgical removal of a tumor. PRRT treatment is based on the administration of a radioactive product, 177-Lu DOTA-0-Tyr3-Octreotate (Lutathera®) and its use before and after surgery is thought to increase the overall survival benefit for patients with SSTR-positive gastroenteropancreatic neuroendocrine tumors GEP-NETs.
Ramucirumab and Trifluridine/Tipiracil or Paclitaxel for the Treatment of Patients With Previously...
Clinical Stage III Gastric Cancer AJCC v8Clinical Stage III Gastroesophageal Junction Adenocarcinoma AJCC v829 moreThis phase II trial studies the effect of the combination of ramucirumab and trifluridine/tipiracil or paclitaxel in treating patients with previously treated gastric or gastroesophageal junction cancer that has spread to other places in the body (advanced). Ramucirumab may damage tumor cells by targeting new blood vessel formation. Trifluridine/tipiracil is a chemotherapy pill and that may damage tumor cells by damaging their deoxyribonucleic acid (DNA). Paclitaxel may block cell growth by stopping cell division which may kill tumor cells. Giving ramucirumab and trifluridine/tipiracil will not be worse than ramucirumab and paclitaxel in treating gastric or gastroesophageal junction cancer.
Intraperitoneal Paclitaxel With XELOX in Gastric Cancer With Peritoneal Metastasis
Stomach NeoplasmsPaclitaxel1 moreIPXELOX will investigate the safety, tolerability, and antitumor activity of intraperitoneal paclitaxel in combination with chemotherapy in patients with advanced gastric cancer with peritoneal metastasis. Study hypotheses: Intraperitoneal paclitaxel administered to subjects at the recommended phase 2 dose will show manageable safety and tolerability and anti-tumor efficacy with systemic capecitabine and oxaliplatin in advanced gastric cancer with peritoneal metastasis.

Gastric CancerGastric cancer with retroperitoneal lymph node metastasis was considered as unresectable, to improve these patients' prognosis, we designed systematic conversion therapy including immunotherapy and chemoradiotherapy. The purpose of this study is to estimate safety and efficacy of Sintilimab in combination with chemoradiothrapy followed by D2 surgical resection in patients with advanced gastric cancer with retroperitoneal lymph node metastasis.
PD-1 Blockade With JS001 Plus Neoadjuvant Chemotherapy for Gastric/Gastroesophageal Junction Cancer...
Stomach NeoplasmsGastric cancer (GC),including cardia and noncardia gastric cancer, is responsible for over 480,000 new cases in 2020 and an estimated 370,000 deaths, making it the third most frequently diagnosed cancer and the third leading cause of cancer death in China. Majority of patients(63%) are presented with locally advanced gastric cancer (stage Ⅱ/Ⅲ) and the prognosis is poor. Previous studies have shown that patients with pathological complete response(pCR) following neoadjuvant therapy have longer survival. In 2019, Lancet Oncology published the FLOT4-AIO study which testified that perioperative chemotherapy with FLOT (5-FU/LV, oxaliplatin and docetaxel) regimen has improved pCR rate and prolonged progression free survival(PFS) and overall survival(OS) in patients with stage II/III gastric cancer. Moreover, PD-1 blockade such as nivolumab or pembrolizumab in combination with chemotherapy has shown higher objective response rate(ORR) as compared to chemotherapy alone in advanced gastric cancer. The nanoparticle albumin-bound paclitaxel has been recommended as the second-line chemotherapy for unresectable or recurrent gastric cancer based on the Chinese Society of Clinical Oncology(CSCO) guideline. When PD-1 antibody is applied, albumin-bound paclitaxel is considered as a better partner since no pretreatment of corticosteroids is needed. Thus, the investigators plan to conduct a phase II clinical trial to evaluate the efficacy and safety of toripalimab (PD-1 antibody) combined with the FLOAP (albumin-bound paclitaxel, oxaliplatin, fluorouracil and leucovorin) regimen as the perioperative treatment of cT2-4 and/or N+ GC. The primary end point is pCR rate. The secondary end points include disease free survival(DFS), OS, ORR, R0 resection rate, incidence of adverse events(AE).
