Cisplatin Treatment Options in Texas

This randomized phase III trial is studying two different combination chemotherapy regimens to compare how well they work in treating young patients with newly diagnosed supratentorial primitive neuroectodermal tumors or high-risk medulloblastoma when given before additional intense chemotherapy followed by peripheral blood stem cell rescue. It is not yet known which combination chemotherapy regimen is more effective when given before a peripheral stem cell transplant in treating supratentorial primitive neuroectodermal tumors or medulloblastoma.

Varian Medical Systems has recently deployed a completely novel radiation treatment system called EthosTM, a first-of-its-kind system that allows for daily adapative radiotherapy (DART), such that the treatment for that day can be created on-the-fly based on the patient's current positioning and anatomy. This system is commercially-available and FDA-approved, and UTSW Radiation Oncology has installed two such units. The ability to adjust the dose delivery every day means both that adaptive therapy is possible with every fraction and that the PTV margin can be dramatically reduced/eliminated, since investigators are treating for that day's patient setup. Investigators are therefore proposing a randomized trial using DART with near marginless (ML) setup margins (a 1 mm margin will be retained for intrafractional motion). Read Less

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin, mitomycin C, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with cisplatin may kill more tumor cells. PURPOSE: This phase II trial is studying how well radiation therapy given together with chemotherapy works in treating patients with stage I bladder cancer. Read Less

The purpose of the phase 1 portion of the study is to determine the safe dose of S-1 and cisplatin that can be administered in gastric cancer patients. The purpose of the phase 2 portion of the study is to determine the antitumor activity of the S-1 and cisplatin regimen established from phase 1 in patients with advanced gastric cancer. Read Less

This is a Phase I, Open-Label study evaluating the PK of S-1 components and their metabolites in patients with advanced solid tumors and varying degrees of hepatic function defined by the NCI classification for hepatic impairment. Patients will be stratified into 4 Cohorts- Normal, Mild, Moderate or Severe. Six patients will be enrolled inot each cohort and receive S-1. Read Less

The purpose of this study is to evaluate the safety and efficacy of S-1 and Cisplatin compared to 5-FU and Cisplatin in treatment of patients with metastatic diffuse gastric and gastro-esophageal junction cancer previously untreated with chemotherapy. Read Less

This is a Phase I, open-label study evaluating the PK of S-1 components and their metabolites in patients with advanced solid tumors and varying degrees of renal function. Patients will be stratified by baseline 24-hour creatinine clearance(CrCL) into 4 cohorts using the normal clearance formula: Group A: Control Group B:Mild renal dysfunction Group C:Moderate renal function and Group D: Severe renal dysfunction. Six patients will be enrolled into each cohort. Read Less

This is an open-label, international, two-arm, parallel, randomized, Phase 3 study evaluating the efficacy and safety of S-1/cisplatin versus 5-FU/cisplatin in patients with advanced gastric cancer previously untreated with chemotherapy for advanced disease. Patients will be randomly assigned (1:1) to S-1/cisplatin (experimental arm) or 5-FU/cisplatin (control arm). Patients will be stratified by number of metastatic sites (one vs. more than one), locally advanced or metastatic disease, prior adjuvant therapy (yes or no), measurable or non-measurable disease, and center.

The purpose of this study is to determine the efficacy and safety of pembrolizumab given concomitantly with chemoradiation (CRT) and as maintenance therapy versus placebo plus CRT in participants with locally advanced head and neck squamous cell carcinoma (LA HNSCC). The primary hypothesis is that pembrolizumab in combination with CRT is superior to placebo in combination with CRT with respect to event-free survival (EFS). Read Less

This study is planned to be conducted in 2 parts: Part 1: Dose Escalation and Part 2: Safety Run-In and Randomized Expansion. The primary objectives of Part 1 are 1) To characterize the safety and tolerability of GS-3583 as monotherapy in participants with advanced solid tumors. 2) To determine the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of GS-3583 as monotherapy in participants with advanced solid tumors. The primary objectives of Part 2 is to assess the safety and tolerability and to determine the RP2D of GS-3583 in combination with zimberelimab (ZIM) and platinum (cisplatin or carboplatin) + 5-fluorouracil (5-FU) chemotherapy in participants with head and neck squamous cell carcinoma (HNSCC) (Cohort A) or in combination with docetaxel in participants with non-small cell lung cancer (NSCLC) (Cohort B).

The purpose of this research study is to test the safety and the benefit of adding pembrolizumab (a therapy that activates the immune system to fight cancer) to standard of care treatment for head and neck cancer. The standard of care treatment will include surgery followed by radiation for 6 weeks. Some patients may also receive cisplatin as standard of care once a week for 6 weeks if the cancer is found to be "high risk". High risk includes cancer that was not completely removed (positive margins) or cancer that has invaded through the outer lining of your lymph nodes. Read Less

The primary focus of this study is to see if looking at tumor biomarkers using a program called coexpression extrapolation or "COXEN" may predict a patient's response to chemotherapy before surgery. Read Less
