Active clinical trials for "Adenocarcinoma"

This phase II trial tests whether 177-Lutetium-PSMA given before stereotactic body radiotherapy (SBRT) works to improve cancer control rate in patients with 1-5 prostate cancer tumors that have come back after prior treatment (oligorecurrent). Radioactive drugs, such as 177-Lutetium-PSMA, may carry radiation directly to tumor cells and not harm normal cells. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving 177-Lutetium-PSMA before SBRT may make the SBRT more effective.

This international, multicenter, randomized, double-blind phase III study intends to recruit 680 patients who have received radical gastrectomy (R0 resection, D2 or more extended lymphadenectomy) with postoperative pathological stage II or III (AJCC Cancer Staging Manual, 8th Edition) gastric or EGJ adenocarcinoma to evaluate the efficacy and safety of JS001 combined with postoperative adjuvant chemotherapy versus placebo combined with postoperative adjuvant chemotherapy.

The objective is to investigate the efficacy and safety of Envafolimab combined with chemotherapy in the treatment of metastatic or recurrent gastric adenocarcinoma.

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: Th1/Tc1: polarization to anti-cancer Th1 and Tc1 subsets, with commensurate down-regulation of immune suppressive Th2 and regulatory T (TREG) subsets; T Central Memory: expression of a T central memory (TCM) phenotype, which promotes T cell engraftment and persistence for prolonged anti-tumor effects; 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; 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 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.

Curative management of locally resectable invasive adenocarcinomas located in the cephalic region of the pancreas (pancreas, duodenum and ampulla of Vater) requires a pancreaticoduodenectomy followed by adjuvant chemotherapy. Pancreaticoduodenectomy is a major surgery that often leads to major complications including approximately 20% of relevant clinical postoperative pancreatic fistula. Postoperative complications following pancreaticoduodenectomy can lead to early discontinuation of the complete oncologic strategy, i.e., chemotherapy for malignancy is performed in only about a third of patients who experienced a grade C fistula. A total pancreatectomy rather than a pancreaticoduodenectomy is an alternative procedure that involves the complete and definitive resection of all pancreatic tissue, eliminating any risk of postoperative pancreatic fistula but is associated with unavoidable endocrine insufficiency and potentially severe metabolic complications, such as "brittle diabetes". Total Pancreatectomy following by intraportal Islet AutoTransplantation (TPIAT) can prevent "brittle diabetes" and improve the quality of life. The endocrine islets can be isolated from the pancreatic surgical specimen with standardized procedures and transplanted in the liver through intraportal infusion, in absence of immunosuppression and allow adequate control of glucose metabolism with a reduced need for exogenous insulin and an effective graft function in 70% of cases at 3 years Thereby, the investigators hypothesize that total pancreatectomy with intraportal Islet autotransplantation rather than classical pancreaticuduodenectomy, in patients with high-risk of postoperative fistula will increase the rate of complete access to adjuvant chemotherapy, while maintaining an adequate metabolic control.

This phase II trial tests whether the combination of nivolumab and ipilimumab is better than nivolumab alone to shrink tumors in patients with deficient mismatch repair system (dMMR) endometrial carcinoma that has come back after a period of time during which the cancer could not be detected (recurrent). Deoxyribonucleic acid (DNA) mismatch repair (MMR) is a system for recognizing and repairing damaged DNA. In 2-3% of endometrial cancers this may be due to a hereditary condition resulted from gene mutation called Lynch Syndrome (previously called hereditary nonpolyposis colorectal cancer or HNPCC). MMR deficient cells usually have many DNA mutations. Tumors that have evidence of mismatch repair deficiency tend to be more sensitive to immunotherapy. There is some evidence that nivolumab with ipilimumab can shrink or stabilize cancers with deficient mismatch repair system. However, it is not known whether this will happen in endometrial cancer; therefore, this study is designed to answer that question. Monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab in combination with ipilimumab may be better than nivolumab alone in treating dMMR recurrent endometrial carcinoma.

This trial will assess the safety and tolerability of Pepinemab in combination with Avelumab in patients with metastatic pancreatic adenocarcinoma that has progressed after first line chemotherapy. Phase 2 will assess the efficacy of this combination therapy.

This is a phase II clinical trial to assess the clinical activity of immunotherapy with E7 TCR-T cells for metastatic HPV-associated cancers. HPV-associated cancers in include cervical, throat, penile, vulvar, vaginal, anal, and other cancers. Participants will receive a conditioning regimen, E7 TCR-T cells, and aldesleukin. Clinical response to treatment will be determined.

The goal of this clinical trial is to assess the ability of Tadalafil alone and in combination with neoadjuvant FLOT (5-Fluorouracil, Oxaliplatin, and Docetaxel) chemotherapy to suppress myeloid derived suppressor cells (MDSCs) in patients with resectable gastric or gastroesophageal junction adenocarcinoma. Resectable means the tumor may be removed through surgical intervention. Neoadjuvant chemotherapy is chemotherapy received before the primary course of treatment i.e.surgical intervention. The main questions it aims to answer are: Is Tadalafil treatment with FLOT feasible and safe? How does tadalafil treatment with FLOT affect the tumor microenvironment (TME)? Will 8 weeks of neoadjuvant exposure to tadalafil with chemotherapy reduce MDSCs in the TME? Participants will receive Tadalafil for 14 days followed by combination of Tadalafil + FLOT for approximately 8 weeks as a part of standard of care neoadjuvant treatment in the window between cancer diagnosis and surgical intervention to remove their tumor. Tumor tissue, blood, and urine will be collected at the start of the study, after 2 weeks of treatment with Tadalafil alone, and around the time of surgical intervention. Saliva will also be collected at the start of the study.
