NCT ID: NCT03044795 Withdrawn - Cancer Clinical Trials

Response to PARP Inhibitor Predicted by the RAD51 Assay

REPAIR
Start date: November 2019
Phase: Phase 2
Study type: Interventional

In tumors with a defect in the homologous recombination (HR) pathway, double-strand break repair is partly impaired. Patients with HR deficient tumors benefit from therapies that induce DNA lesions requiring HR for repair. These therapies include platinum compounds and inhibitors of the enzyme PARP-1. At this moment, selection for PARP inhibitor treatment relies on detection of germ-line or somatic mutations in the HR pathway genes BRCA1 or BRCA2. However, not all HR deficient tumors have a BRCA gene mutation, the BRCA genes can also be silenced by promoter methylation. Moreover, the HR pathway can be defective due to mutations in other HR genes. In addition, the presence of a BRCA gene mutation does not guarantee defective HR since mutations in other genes (e.g. TP53BP1) can restore HR despite the presence of a BRCA1 mutation. Since all patients with tumors that are HR deficient may benefit from PARP inhibition, better tools are required to identify these patients. Recently, a functional ex vivo test for HR deficiency (the RAD51 assay) became available for clinical use. The RAD51 assay can identify patients with functional defects in HR-repair and may predict which cancer patients are likely to benefit from PARP inhibition. The purpose of this study is to investigate whether the RAD51 assay can select patients who will benefit from treatment with the PARP-inhibitor veliparib.

Impact of Early Implementation of Narrative Medicine Techniques on Patient Centered Attitudes of Medical Students

Start date: March 1, 2017
Phase:
Study type: Observational

A qualitative study assessing the impact of early narrative medicine practice on Medical Honors Program (MHP) students' attitudes regarding patient-centered interactions, through interviewing patients with chronic or life-limiting illnesses to obtain their illness stories. MHP students will develop a patient narrative for the patients interviewed. These narratives will be edited by the patient, and, with the permission of the patients, may be published as a collection of stories.

Two Radiation Dose Schedules of SBRT to Lung Metastases < 5cm in Dimension

Start date: October 26, 2017
Phase: Phase 2
Study type: Interventional

30 Gy single fraction of SBRT for lung metastases will result in comparable oncologic outcomes to 18Gy in three fractions (or dosing to a BED </-100Gy at the discretion of the radiation oncologist) with respect to disease control and toxicity.

NCT ID: NCT02939846 Withdrawn - Cancer Clinical Trials

Pharmacokinetics of Single and Repeat Oral Doses of Trametinib in Chinese Subjects With Solid Tumours

Start date: May 2017
Phase: Phase 1
Study type: Interventional

Present clinical study will be conducted in China to evaluate the pharmacokinetics of single and repeat oral doses of trametinib, the safety profile and the clinical activity in Chinese subjects with solid tumor. Approximately 10 evaluable subjects will be enrolled in the study, Subjects will receive trametinib 2 mg once daily (QD). Study treatment will continue until disease progression, death or unacceptable toxicity. The study will be completed after all subjects have discontinued from study treatment or last enrolled subject has had at least 16 weeks of follow-up, whichever occurs first.

NCT ID: NCT02914327 Withdrawn - Cancer Clinical Trials

Safety and Activity of SNX-5422 Plus Ibrutinib in CLL

Start date: February 2, 2017
Phase: Phase 1
Study type: Interventional

SNX-5422 is a prodrug of SNX-2112, a potent, highly selective, small molecule inhibitor of the molecular chaperone heat shock protein 90 (HSP90). Hsp90 inhibitors may overcome ibrutinib resistance in Mantle cell lymphomas and this study will investigate whether the addition of SNX-5422 to an established dose of ibrutinib will result in the removal of mutated BTK from blood mononuclear cells and/or prevents or delays disease progression of subjects with CLL

The Role of Emotions and Regulatory Focus in Decision Making That Involves Risk Tradeoffs

Start date: June 5, 2019
Phase:
Study type: Observational

Background: People with cancer often have to make complex decisions about their treatment. For some of these decisions, they have to weigh the benefits of a treatment against its side effects. They may have to think about its potential to increase the risk of another disease. One example is hormone replacement therapy. That reduces a woman s risk of getting colorectal cancer, but it raises her risk of getting breast cancer. Researchers want to learn more about how people make tradeoff decisions like these. Objective: To learn about how people respond to information about hypothetical health and medical treatment options. Eligibility: Adults ages 18 70. Design: Participants will have one 30-minute visit. Participants will complete a series of short questionnaires. These will be about their beliefs and values. Some may be about cancer and heart disease risk. Participants ages 18 to 29 will answer questions about sexual health. Participants will write a paragraph or two about a room in their house or about a life event. Participants will read a series of stories. These will describe different hypothetical health treatments. The stories describe a pill that lowers the risk of one health condition, but raises the risk for another. After each story, participants will note how willing they are to take the pill. Participants will answer questions about the information that they got. They will also answer questions about their health, beliefs, and opinions. Participants will do 2 attention tasks computer.

Anabolic Response Cancer

Start date: May 2016
Phase: N/A
Study type: Interventional

Weight loss and muscle wasting commonly occurs in patients with cancer, negatively influencing their quality of life, treatment response and survival. Weight changes in patients with cancer may be the consequence of energy imbalance and disturbances in protein metabolism, poor treatment tolerance, hormonal alterations, systemic inflammation etc. This results in body composition modifications in favor of fat gain and/or lean body mass loss in early stage cancer. However, in advanced cancer mostly loss of both fat mass and lean mass has been found. Unfortunately, gains in muscle mass are difficult to achieve. In a previous study of the Investigators, a bolus (15 g) of an essential amino acid mixture as present in milk protein was able to stimulate whole-body protein anabolism equally and effectively in weight-losing patients with lung cancer. This indicates the high potential of proteins with high essential amino acids as therapeutic agents to increase muscle mass in these patients. However, the dose-response effect to reach optimal whole-body protein anabolism is yet unknown and can differ among patients. Therefore, the Investigators would like to study the effects of several dosages of a protein with high essential amino acid levels, administered by sip feeding, on whole-body protein anabolism in patients with cancer in comparison with healthy older adults. Furthermore, the individual protein requirements of cancer patients may be established as this is the cornerstone of nutritional support. Specifically to establish 'the anabolic threshold', when protein breakdown equals synthesis and the response and the relation between protein intake and net protein synthesis are critical.

NCT ID: NCT02782871 Withdrawn - Cancer Clinical Trials

RCT: Compare - Pneupac VR1 to Manual Ventilation in Intubated Patients

Start date: June 2016
Phase: N/A
Study type: Interventional

Following major head and neck surgery it may be necessary to keep patients intubated and ventilated for at least 12 hours to allow the swelling associated with the operation to subside. Therefore patients (participants) are transferred to the intensive care unit anaesthetised, in-tubated and ventilated. Current practice is that patients are manually ventilated, by hand, during transfer from the operating theatre to the intensive care unit.
