Filter by:This is a proof of concept study (a study to initially assess the benefit a new drug indication) of the combination of two investigational drugs cediranib and olaparib in patients with ovarian cancer whose cancer worsened despite previously receiving a poly (ADP-ribose) polymerase (PARP) inhibitor (such as olaparib). The purpose of this study is to find out whether taking cediranib and olaparib at the same time will be able to stop tumors from growing further or shrink it. Cediranib works by blocking (inhibiting) several specific proteins in cancer cells called the vascular endothelial growth factor (VEGF) receptors. These proteins are important in the formation of blood vessels to the tumor. It is believed that many tumors survive because the blood vessels on the tumors bring oxygen and nutrients to the cancer cells which enable them to grow. If the formation of the blood vessels is blocked, the tumor cells may die. Olaparib, works by blocking a protein called poly [adenosine diphosphate-ribose] polymerase (PARP). PARP is an important protein which tries to fix damaged deoxyribonucleic acid (DNA, molecules that contain important instructions for the development of cells). Many cancers are thought to develop from damaged DNA. By blocking PARP from fixing damaged DNA, the tumor cells may die. Adding cediranib to olaparib, and therefore blocking several different mechanisms for cancer growth, may stop tumor growth.
The purpose of this study is to determine whether or not there are more complications in the extraperitoneal compared with the transperitoneal approach for laparoscopic aortic lymphadenectomy for the surgical staging of endometrial or ovarian cancer
This study will assess the efficacy and safety of pembrolizumab (MK-3475) monotherapy in female participants with recurrent ovarian cancer (ROC) who have received up to 5 prior lines of treatment including platinum-based treatment for ROC (1 to 6 total prior lines counting front line therapy). Participants will be enrolled into two separate cohorts based on the number of prior lines of treatment received for ROC. There will be no hypothesis testing in this study.
This is a phase I prospective study with the primary objective to compare the efficacy and safety of Surgical cytoreduction (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in treatment of recurrent ovarian, primary peritoneal or fallopian tube cancers. Eligible patients consenting to this protocol will undergo their scheduled surgical procedure. After surgical cytoreduction to a residual disease ≤ 2.5 mm, a single dose of carboplatin (800 mg/m2) will be administered in normal saline via intraperitoneal hyperthermic perfusion using the closed-abdomen. HIPEC will be continued for 90 minutes in the hyperthermic phase (41°C-43°C). At 4-6 weeks after CRS, patients will go on to receive 6 cycles of standard IV platinum-based chemotherapy. The proportion of patients who are without evidence of recurrence will be assessed at 6, 9, 12 and 18 months after the day of surgery.
Brain metastases are the most common intracranial malignancy occurring in 20-40% of all cancers, and the presence of CNS metastases is associated with a poor prognosis. As such, the median overall survival of patients with symptomatic brain lesions is a dismal 2-3 months regardless of tumor type. Because standard chemotherapy largely does not cross the blood brain barrier at a meaningful concentration, standard treatment is limited and usually involves surgical resection and/or stereotactic radiosurgery for isolated lesions and whole brain radiation for multiple lesions. Unfortunately, the median overall survival is only improved by about 6 months with this multimodality approach2, and there is a paucity of second-line therapies to treat recurrence. Furthermore, re-resection and re-radiation are often not feasible options due to concern for increasing complications or neurotoxicity, respectively. Thus, there is a dire clinical need for additional treatment options for this patient population. Checkpoint blockade therapy, in particular PD-1 and PD-L1 inhibition, has recently shown clinical efficacy in multiple types of solid tumors. The investigators propose to study the efficacy of checkpoint blockade therapy in patients with solid tumors and refractory/recurrent brain metastases. The investigators will assess the efficacy of MEDI4736, a novel PD-L1 inhibitory monoclonal antibody, in this study.
The treatment of advanced ovarian cancer is based on the combination of chemotherapy based on platinum salt and surgery whose quality is the major prognostic factor. A meta-analysis of retrospective series had shown that for every 10% increase in the complete cytoreduction rates were increased by 5.5% overall survival time (Markman et al, 2001). Currently, it is recognized that the best chance of survival conferred to patients whose initial surgical residue is zero (Harter et al, 2009). However, even if macroscopically complete surgery and whatever the type of systemic chemotherapy, peritoneal recurrence remains high for more than 75%. To reducing it of recurrence, a therapeutic approach is to administer chemotherapy intraperitoneally. The intraperitoneal chemotherapy consists to administer the drug directly into the peritoneal cavity. Alberts et al, 1996 and Armstrong et al, 2006 compared the efficacy in terms of survival of an intraperitoneal chemotherapy according to this method with a conventional systemic chemotherapy. Alberts reported a significant improvement in the median overall survival. Armstrong shows in addition a decreased risk of recurrence. It must be remembered that: - The establishment of an intra-abdominal catheter does not always ensure complete flow of drugs into the peritoneal cavity (major postoperative adhesions). - There may be problems of catheters becoming blocked and requiring local treatment; these problems can cause abdominal pain whose care is difficult. Thus almost half of patients fail to get all six courses of intraperitoneal chemotherapy. Thus, the investigators propose to estimate the flow of intraperitoneal chemotherapy with IP peritoneal scintigraphy, using a radiotracer (nanocis®). The investigators hypothesize that the movement of colloids in peritoneal cavity is similar to the circulation of chemotherapy within the peritoneal cavity (From Forni et al, 1993, Varia et al, 2003, Young et al, 2003, Dawson et al, 2011). The accumulation of radiotracer will be more correlated with abdominal pain sites described by the patient as well as peritoneal recurrence sites found during monitoring.
This is a randomized phase II study, aimed at evaluating the efficacy (through progression free survival at 6 months) and safety of 5 different treatments involving atezolizumab, bevacizumab and/or acetylsalicylic acid in advanced recurrent platinum-resistant ovarian cancer patients in order to select the optimal treatments for further development in Phase III.
This pilot early phase I trial studies how adavosertib affects the tumor deoxyribonucleic acid (DNA) of patients undergoing surgery for high grade (fast growing or aggressive) ovarian, fallopian tube, or primary peritoneal cancer that has spread to other places in the body (advanced). Certain characteristics in the DNA of these patients may affect how well they respond to treatment. Learning how adavosertib affects DNA in tumor cells may help doctors plan effective treatment.

This Phase 1/2 study will evaluate the safety and efficacy of combination treatment with niraparib and pembrolizumab (MK-3475) in patients with advanced or metastatic triple-negative breast cancer or recurrent ovarian cancer. (KEYNOTE-162)
