Filter by:The purpose of this study is to gain a better understanding of access to clinical and research resources for families of children affected with a phosphatase and tensin homology (PTEN) mutation. Ultimately, the researchers hope to be able to use this information to develop a standard of care for affected individuals and their family members. Family members/legal guardians of an individual with a PTEN mutation enrolled in the Rare Diseases Clinical Research Network (RDCRN) Contact Registry will be invited via email to participate in this study.
Phosphatase and TENsin homolog (PTEN) gene germline mutations are associated with a spectrum of clinical manifestations characterized by neurocognitive deficits, intellectual disability, autism symptomatology, skin lesions, macrocephaly, hamartomatous overgrowth of tissues, and an increased risk of cancers. Investigators are conducting research to evaluate the potential safety and efficacy of RAD001 (everolimus) in this patient population, and the potential neurocognitive benefits from treatment with RAD001 or placebo for a six month period. The investigators hope this trial will lead to a better understanding of PTEN and to new forms of treatment that may benefit children and adults with PTEN in the future.
This is a Phase 1 single site study to evaluate the safety and efficacy of a combination therapy that includes the administration of vismodegib and photodynamic therapy (PDT) using aminolevulinic acid (20 percent ALA) for multiple basal cell carcinomas. All subjects will receive vismodegib 150mg by mouth every day for 3 months, and undergo three PDT sessions with topical application of ALA. The PDT will be first administered at 7+ 4 business days after the beginning of the Erivedge and at 45 + 5 business days and then at 90 + 10 business days. Primary Objective The primary objective of this study is to determine the safety of photodynamic therapy (PDT) with vismodegib (combination therapy) for patients with multiple BCC. 3.2 Secondary Objective To evaluate the overall response rate (ORR) to the combination therapy in patients with multiple BCCs.ORR is defined as the proportion of evaluable study subjects who has complete or partial response to the study treatment.
This randomized, double-blind, regimen-controlled, phase II, multicenter study will assess the efficacy and safety of two different vismodegib regimens in participants with multiple basal cell carcinoma. Participants will receive vismodegib 150 mg orally once daily either in an intermittent schedule of 12 weeks vismodegib followed by 8 weeks placebo (Arm A) or as 24 weeks induction followed by an intermittent schedule of 8 weeks placebo followed by 8 weeks vismodegib (Arm B). Anticipated time on study treatment is 72 weeks.
Background: People with phosphatase and tensin homolog deleted on chromosome 10 (PTEN) hamartomatous tumor syndromes (PHTS) have a mutation in one of their genes called PTEN that can lead to benign tumors called hamartomas throughout the body. This puts them at increased risk for breast, thyroid and endometrial cancer. People with a PTEN mutation have increased activity of proteins such as protein kinase B (AKT) and mammalian target of rapamycin (mTOR), which may be responsible for tumor growth and their increased risk of these cancers. Experiments show that a drug called sirolimus, which is used to prevent the immune system from rejecting transplanted organs, can inhibit cancer cell growth by blocking the mTOR protein. Objectives: To test the ability of sirolimus to decrease the activity of proteins that are regulated by mTOR in both benign and cancerous tumor tissue. Eligibility: People 18 years of age and older with Cowden syndrome or other PHTS. Design: Sirolimus treatment. Patients take sirolimus once a day in 28-day treatment cycles. Patients who do not have cancer take the drug for a total of two cycles (56 days) unless they develop unacceptable side effects. Those who have cancer may continue sirolimus beyond cycle 2 until their disease worsens or they develop unacceptable side effects. Evaluations. Patients come to the clinic for a history and physical examination on day 1 of every treatment cycle, then every month for the first two months off therapy, and then at 6 and 12 months. In addition, they have the following procedures: - Positron emission tomography (PET) scan and neuropsychological testing before starting treatment. - Clinical photography (photographic documentation of skin lesions) before starting treatment. Patients who do not have cancer have repeat photography at 2 and 8 weeks and then, if the lesions shrink or go away while on therapy, again every month for the first 2 months off sirolimus, then at 6 months and 1 year. Patients who have cancer and continue treatment beyond 8 weeks have repeat photography every 8 weeks while on the study. - Digital dermoscopy (skin lesion examination using a high resolution camera). This is done at the same intervals as clinical photography. - Multiple biopsies of the skin and lower intestine, and possibly the tumor in patients with cancer, before starting treatment, at 2 weeks of treatment and at 8 weeks of treatment. - Blood and urine tests every week while on treatment for the first two cycles, then every 4 weeks for patients who continue treatment beyond two cycles. - Imaging studies, such as computerized tomography (CT), ultrasound or magnetic resonance imaging (MRI) in patients with cancer before starting treatment and again every two cycles to monitor the tumor size and location.
This is a first-in-human, phase I/Ib clinical research study with BEZ235, an inhibitor of phosphatidylinositol 3'-kinase (PI3K). The study consists of a dose escalation part followed by a safety dose expansion part: Dose escalation part (advanced solid tumors, including patients with breast cancer being treated with trastuzumab): Patients receive oral BEZ235 once daily on days 1-28 of the first course. Courses will repeat every 28 days in the absence of disease progression or unacceptable toxicity. Cohorts of at least 3 patients receive escalating doses of BEZ235, as single agent or in combination with trastuzumab, until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose expected to produce during the first course of treatment dose-limiting toxicity in 33% of patients. Once the MTD has been defined, the safety expansion parts of the trial will be opened for enrollment. Safety dose expansion part (advanced solid tumors, including patients with breast cancer being treated with trastuzumab): Patients will be treated with BEZ235, as single agent or in combination with trastuzumab, given at the MTD, once daily. Treatment of patients will continue until disease progression or occurrence of unacceptable side effects.
This is a phase I/II clinical research study with BGT226, an inhibitor of phosphatidylinositol 3'-kinase (PI3K). The study consists of a Phase I dose escalation part followed by a safety expansion part and a Phase II expansion part. Once the MTD has been defined, the safety expansion and efficacy expansion parts of the trial will be opened for enrollment. Phase I safety expansion part will enroll advanced solid tumors. Phase II expansion part will enroll advanced breast cancer. An effort will be made to enrich the trial population with Cowden Syndrome patients with advanced solid malignancies.
This is a continuing study which evaluates the long-term safety and efficacy of oral acitretin in an open manner in the treatment of psoriasis, cutaneous disorders of keratinization, multiple basal cell carcinomas and other retinoid responsive diseases.
