Emergence of Bacterial Resistance to Antibiotics in the Digestive Microbiota of Patients Treated With Anticancer Drugs

Solid cancers are frequently treated with chemotherapies that target the DNA of cancer cells. It has recently come to light that bacteria are also the target of chemotherapies used in oncology. The results of current studies demonstrate the close link between the composition of the microbiota, the immune system, toxicity and the efficacy or otherwise of anti-cancer treatments.

In this context, the study will measure the influence of treatment with anticancer molecules known to activate the bacterial SOS response on the emergence of antibiotic-resistant commensal bacteria in the gut microbiota of cancer patients. Furthermore, this study will investigate the existence of a close link between changes in the intestinal microbiota determined by the induction or non-induction of the SOS response, bacterial translocation, the integrity of the intestinal barrier and the antitumor immune response.

The RAMA trial plans to collect stool and blood samples from two different cohorts of patients:

* Unexposed cohort: patients receiving anti-cancer treatment that does not induce bacterial SOS response.
* Exposed cohort: patients receiving anti-cancer treatment inducing the bacterial SOS response.

Patients' stools will be collected within 7 days of their first chemotherapy treatment and within 7 days of the 3rd chemotherapy cycle. Two blood samples will be taken at the same time as the stool samples.

The results obtained from this prospective clinical research will then be investigated in two experimental laboratory models.

The aim is to demonstrate that cytotoxic anticancer drugs promote the emergence of antibiotic-resistant commensal bacteria, by means of this large-scale study comprising a clinical component, which is the subject of the research presented in this protocol, combined with laboratory research components.

A Multiple Ascending Dose Study of MEDI7247 in Advanced or Metastatic Solid Tumors

To assess safety and tolerability, describe the dose-limiting toxicities, assess the preliminary antitumor activity, determine the maximum tolerated dose (MTD) or the highest protocol-defined dose (maximum administered dose) in the absence of establishing the MTD, and a recommended dose for further evaluation of MEDI7247 in patients with selected advanced or metastatic solid tumor malignancies that have received at least 1 prior line of treatment.

B-Receptor Signaling in Cardiomyopathy

We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

Gamma-Secretase Inhibitor RO4929097 and Gemcitabine Hydrochloride in Treating Patients With Advanced Solid Tumors

This phase I trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 when given together with gemcitabine hydrochloride in treating patients with advanced solid tumors. Gamma-secretase inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving gamma-secretase inhibitor RO4929097 together with gemcitabine hydrochloride may kill more tumor cells.

A Pan-European Study on Minimally Invasive Versus Open Pancreatoduodenectomy in High-volume Centers

RATIONALE: Minimally-invasive pancreatoduodenectomy (MIPD), either laparoscopic or robot-assisted, has been suggested as a valuable alternative to open pancreatoduodenectomy (OPD). The generalizability of the current literature is, however, unknown since randomized studies are lacking, and current data are published from few, very high volume centers and selection bias with a lack of case-matched series. International studies are lacking completely.

OBJECTIVE: To compare outcomes of MIPD versus open pancreatoduodenectomy (OPD), in high-volume European pancreas centers (>10 MIPDs per year, total >20 PDs per year).

METHODS: A retrospective multicenter propensity-score matched cohort study including all consecutive patients who underwent MIPD (or MI total pancreatectomy) between January 2012 and December 2016, for pancreatic head, bile duct, or duodenal cancer or cysts except chronic pancreatitis. Predefined electronic case report forms will be disseminated amongst participating centers. Participants are responsible for their own data collection. Matching of MIPD cases (collected from participating centers) to OPD controls (extracted from Dutch and German national registries) will be based on propensity scores determined by logistic regression including preoperative variables: year of surgery, demographics, BMI, ASA, comorbidities, tumor size, tumor etiology (diagnosis), and multivisceral resection. Primary outcome is 90-day major morbidity(Clavien-Dindo ≥ 3a). Secondary outcomes are 90-day postoperative events including: pancreatic fistula, length of hospital stay, R0 (microscopically negative) resection margin, malignant lymph node ratio, days to adjuvant therapy and overall survival.

Atezolizumab and Bevacizumab in Treating Patients With Rare Solid Tumors

This phase II trial studies how well atezolizumab and bevacizumab work in treating patients with rare solid tumors. Immunotherapy with monoclonal antibodies, such as atezolizumab and bevacizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Clinical Trial of High-dose Vitamin C for Advanced Pancreatic Cancer

This is a phase II study. It is designed to provide information about if high-dose ascorbate (vitamin C) increases survival for pancreatic cancer patients. The hypothesis is that vitamin C is well tolerated and increases cancer treatment effectiveness, lengthening survival time for patients with advanced pancreatic cancer.

Using NPT to Evaluate Providing PPC as ELNEC-PPC WBT for Nurses

The purpose of this study is to explain the provision of palliative care at the end of life by the implementation of the ELNEC course, as WBT Program using the Normalization Process Theory, that focus attention on how complex interventions become routinely embedded in practice. In addition to, identify the changes implemented by the participant nurses (intervention group) in their clinical practice, after participating in WBT Program to provide Palliative Care alongside with usual care versus usual care only (control group) for children with life-limiting conditions or in the case of accidents/sudden death, at the end of life. And finally, provide findings that will assist in the interpretation of the trial results.

Comparing the Efficacy of Endoscopic FNA vs FNB in Diagnosing Solid Gastrointestinal Lesions

The purpose of this study is to determine if fine needle aspiration or fine needle biopsy is more efficacious and cost-effective than the other while maintaining diagnostic accuracy in the setting of solid gastrointestinal lesions.

Milademetan in Advanced/Metastatic Solid Tumors

Phase 2, multicenter, single-arm, open-label basket study designed to evaluate the safety and efficacy of milademetan in patients with advanced or metastatic solid tumors refractory or intolerant to standard-of-care therapy that exhibit wild-type (WT) TP53 and MDM2 copy number (CN) ≥ 8 using prespecified biomarker criteria.
