open study

An open-labeled, interventional pilot trial, 10 youth with AVP-D and 10 PD matched for age, sex, and BMI will be recruited from Pediatric Endocrinology and Neuroendocrinology at Massachusetts General Hospital and in the community. This study tests the hypothesis that oral estrogen/progestin will stimulate endogenous oxytocin release in control subjects. Eligible participants will receive two tablets in a single administration containing a total of 1 mg of norethindrone acetate 70 mcg of ethinyl estradiol. Sampling for blood and saliva will take place at baseline and approximately 24 hours following study drug administration. Neuropsychological assessment (anxiety, mood and emotion regulation; impulse control; aberrant eating behaviors; social cognition and functioning; quality of life) will be assessed at baseline to characterize the study population.

This phase III trial compares the effect of decreased number of radiation (ultra-hypofractionated) treatments to the usual radiation number of treatments (hypofractionation) with standard of care chemotherapy, with cisplatin, gemcitabine or mitomycin and 5-fluorouracil for the treatment of patients with muscle invasive bladder cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a short period of time. Ultra-hypofractionated radiation therapy delivers radiation over an even shorter period of time than hypofractionated radiation therapy. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. Chemotherapy drugs, such as mitomycin-C and 5-fluorouracil (5-FU), work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ultra-hypofractionated radiation may be equally effective as hypofractionated therapy for patients with muscle invasive bladder cancer.

In 2016, one in five individuals in the United States (US) experienced chronic pain, and approximately 40% of them suffered from neuropathic pain. The physical and emotional burden on patients results in costs of billions of dollars annually. Digital amputations affect over 23,000 people each year in the US and may lead to neuropathic pain and neuroma formation in the transected nerves. Previous studies have reported a 6.6% incidence of symptomatic neuroma, and more than 60% of these patients require surgery to reduce the negative impact on their daily living activities. To minimize neuroma formation after digital amputation, various techniques have been described, such as traction neurectomies (TN) and dorsal transpositions (DT), with and without nerve coaptation. However, it remains unclear whether these techniques improve patient-reported outcome measures in individuals undergoing this type of procedure. Previously published studies are descriptive in nature, focus on a single surgical technique, or include patients with established symptomatic neuromas. The only prospective trial on this topic was published in 2000 and compared two conventional techniques that have since been modified to better minimize neuroma formation or to reduce mechanical pressure by transposing the nerve ends to the dorsal aspect of the hand. However, that study used different scales to measure outcomes and did not incorporate aspects of pain that affect patients' emotional and social well-being. Currently, two randomized controlled trials are enrolling patients. One compares surgical techniques for the treatment of neuroma rather than its prevention. The other excludes digits with injuries located distal to the interphalangeal joints. Both studies focus on more complex surgical techniques. Given the extent of this problem, there has been recent innovation aimed at preventing neuroma formation. One promising product is the Tulavi Allay™ Nerve Cap, which has demonstrated encouraging results in basic science studies and anecdotally in early clinical use cases. In this study, the investigators have designed a prospective trial to assess the efficacy of the Tulavi Allay™ Nerve Cap when used to prevent symptomatic digital nerve neuroma following traumatic digital amputation.

An exercise regimen (PRIME: Proximal Resistance In-House Movement Exercise) has been designed for patients with myotonic dystrophy type 2 (DM2). The hypothesis is that this patient-friendly physical therapist (PT)-guided exercise program associates with improved functional capacity and muscle composition in DM2 in this two-period two-sequence cross-over study. Thus, participant will be randomized to one of the three possible groups. Participants in GROUP A will perform exercise routine virtually under the direct supervision of a physical therapist once a week and another session on their own for the first three months, then they will continue with same exercise routine at home for the last 3 months on their own. Participants in GROUP B will perform exercise routine virtually under the direct supervision of a physical therapist twice a week for the first three months, then they will continue with same exercise routine at home for the last 3 months on their own. Participants in GROUP C will perform exercise routine on their own during the first 3 months, then they will perform exercise routine virtually under the direct supervision of a physical therapist. Each group will include around 8 participants. Duration of the study is 6 months. In addition to exercise sessions, participants will have evaluation of their strength, motor function and muscle composition at three time points: initiation, 3 months and completion of the study at 6 months. Muscle composition will be assessed by electrical impedance myography which is a portable, non-invasive, painless and non-radiation tool that applies a weak high multifrequency electrical current to the examined muscle and allows to obtain information about its composition.

The purpose of this clinical trial (called the FLOTILLA study) is to give continued access to the study medicines, as well as safety follow-up, for participants in prior clinical trials of encorafenib and/or binimetinib. All participants who took part in earlier encorafenib and/or binimetinib studies may participate the FLOTILLA study if they are still benefiting from the use of the study medicines. This will be determined by the study doctor. People may not participate in the FLOTILLA study if they have not enrolled in a prior study of encorafenib or binimetinib. Participants that had enrolled but had stopped receiving the study treatment in a prior study cannot enrolled in this study. Participants in the FLOTILLA study will receive encorafenib and/or binimetinib at the same dose and frequency as in their prior study, for up to about 5 years.
