Gastric Cancer Clinical Trials

The therapy of solid tumors has been revolutionized by immune therapy, in particular, approaches that activate immune T cells in a polyclonal manner through blockade of checkpoint pathways such as PD-1 by administration of monoclonal antibodies. In this study, the investigators will evaluate the adoptive transfer of RAPA-201 cells, which are checkpoint-deficient polyclonal T cells that represent an analogous yet distinct immune therapy treatment platform for solid tumors. RAPA-201 is a second-generation immunotherapy product consisting of reprogrammed autologous CD4+ and CD8+ T cells of Th1/Tc1 cytokine phenotype. First-generation RAPA-101, which was bred for resistance to the mTOR inhibitor rapamycin, demonstrated clear anti-tumor effects in multiple myeloma patients without any product-related adverse events. Second-generation RAPA-201, which have acquired resistance to the mTOR inhibitor temsirolimus, are manufactured ex vivo from peripheral blood mononuclear cells collected from solid tumor patients using a steady-state apheresis. RAPA-201 is also being evaluated for the therapy of relapsed, refractory multiple myeloma and was granted Fast Track Status by the FDA for this indication. The novel RAPA-201 manufacturing platform, which incorporates both an mTOR inhibitor (temsirolimus) and an anti-cancer Th1/Tc1 polarizing agent (IFN-alpha) generates polyclonal T cells with five key characteristics: 1. Th1/Tc1: polarization to anti-cancer Th1 and Tc1 subsets, with commensurate down-regulation of immune suppressive Th2 and regulatory T (TREG) subsets; 2. T Central Memory: expression of a T central memory (TCM) phenotype, which promotes T cell engraftment and persistence for prolonged anti-tumor effects; 3. Temsirolimus-Resistance: acquisition of temsirolimus-resistance, which translates into a multi-faceted anti-apoptotic phenotype that improves T cell fitness in the stringent conditions of the tumor microenvironment; 4. T Cell Quiescence: reduced T cell activation, as evidence by reduced expression of the IL-2 receptor CD25, which reduces T cell-mediated cytokine toxicities such as cytokine-release syndrome (CRS) that limit other forms of T cell therapy; and 5. Reduced Checkpoints: multiple checkpoint inhibitory receptors are markedly reduced on RAPA-201 cells (including but not limited to PD-1, CTLA4, TIM-3, LAG3, and LAIR1), which increases T cell immunity in the checkpoint-replete, immune suppressive tumor microenvironment. This is a Simon 2-stage, non-randomized, open label, multi-site, phase I/II trial of RAPA-201 T immune cell therapy in patients with advanced metastatic, recurrent, and unresectable solid tumors that have recurred or relapsed after prior immune therapy. Patients must have tumor relapse after at least one prior line of therapy and must have refractory status to the most recent regimen, which must include an anti-PD-(L)1 monoclonal antibody. Furthermore, accrual is limited to solid tumor disease types potentially amenable to standard-of-care salvage chemotherapy consisting of the carboplatin + paclitaxel (CP) regimen that will be utilized for host conditioning prior to RAPA-201 therapy. Importantly, carboplatin and paclitaxel are "immunogenic" chemotherapy agents whereby the resultant cancer cell death mechanism is favorable for generation of anti-tumor immune T cell responses. Thus, the CP regimen that this protocol incorporates is intended to directly control tumor progression and indirectly promote anti-tumor T cell immunity. The CP regimen is considered standard-of-care therapy for the following tumor types, which will be focused upon on this RAPA-201 protocol: small cell and non-small cell lung cancer; breast cancer (triple-negative sub-type or relapse after ovarian ablation/suppression); gastric cancer (esophageal and esophageal-gastric-junction adenocarcinoma; gastric adenocarcinoma; esophageal squamous cell carcinoma); head and neck cancer (squamous cell carcinoma of oral cavity, larynx, nasopharynx, and other sites); carcinoma of unknown primary; bladder cancer; and malignant melanoma. Protocol therapy consists of six cycles of standard-of-care chemotherapy (carboplatin + paclitaxel (CP) regimen) administered every 28 days (chemotherapy administered on cycles day 1, 8, and 15). RAPA-201 cells will be administered at a target flat dose of 400 X 10\^6 cells per infusion on day 3 of cycles 2 through 6. A sample size of up to 22 patients was selected to determine whether RAPA-201 therapy, when used in combination with the CP regimen, represents an active regimen in solid tumors that are resistant to anti-PD(L)-1 checkpoint inhibitor therapy, as defined by a response rate (≥ PR) consistent with a rate of 35%. The first stage of protocol accrual will consist of n=10 patients; to advance to the second protocol accrual stage, RAPA-201 therapy must result in a tumor response (≥ PR) in at least 2 out of the 10 initial patients.

The iCaRe2 is a multi-institutional resource created and maintained by the Fred \& Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies. Read Less

This study intends to explore feasibility, acceptability, and outcomes related to the use of a digital health coaching intervention for individuals who have completed primary therapy for cancer. Up to 625 individuals with diverse cancer diagnoses will be enrolled across up to 8 clinical sites to participate in a randomized wait-list control study. Those in the intervention group will receive 6 months of digital coaching up front followed by 6 months of ongoing monitoring via patient reported and clinical outcomes, as well as wearable data. Those in the control group will be monitored via patient reported and clinical outcomes as well as wearable data for the first 6 months followed by 6 months of digital health coaching. Both groups will collect fecal microbiome samples at enrollment and month 6. The study aims to explore if and how digital health coaching may be used to enhance outcomes for individuals following completion of primary cancer therapy. Read Less

Gastric cancer afflicts 27,000 Americans annually and carries a dismal prognosis. One reason for poor outcomes is late diagnosis, as the majority of gastric cancers in the United States are diagnosed at a relatively advanced stage where curative resection is unlikely. Gastric precursors (such as atrophic gastritis and intestinal metaplasia) are precancerous changes to the stomach mucosa which increases risk for subsequent gastric cancer. The Gastric Precancerous Conditions Study (GAPS) is an observational study of patients at elevated risk for gastric cancer. Investigators seek to recruit patients from endoscopy unit of Stanford Health Care, a large academic network of hospitals and clinics serving Northern California. Investigators will recruit patients who are both symptomatic (e.g. dyspepsia) and asymptomatic (e.g. referred for screening), and individuals both with known precursor lesions (such as intestinal metaplasia) or at high risk for carrying precursor lesions. A component of the study is long-term follow-up of individuals with gastric precursors. This is to understand their risk factors for histologic progression and regression. During both index and subsequent endoscopies, the study team will collect biospecimens (e.g. blood, saliva, gastric tissue). Read Less
