This study will enroll participants with myelodysplastic syndromes (MDS) with an Isocitrate dehydrogenase protein, 1 (IDH1) mutation, who have not received treatment with a hypomethylating agent previously. Participants will be randomized to receive either ivosidenib (IVO) alone or azacitidine (AZA) alone. IVO will be administered daily throughout the 28-day treatment cycle and AZA will be administered for the first 7 days of each 28-day cycle. Study visits will be conducted every week during Cycle 1 (Days 1, 8, 15, and 22), and Day 1 of each cycle thereafter. After the last dose of treatment, participants will attend an safety follow-up visit and participants will be followed to assess overall survival. Study visits may include a bone marrow aspirate, physical exam, echocardiogram (ECHO), electrocardiogram (ECG), blood and urine analysis, and questionnaires.

This is a research study in women to compare the outcomes of two procedures that restore blood flow to the arteries of the heart. In one procedure the blockages are ballooned and then stented with a small wire mesh tube through a small incision in the wrist or the groin. The other procedure is an open-heart operation in which healthy blood vessels from inside the chest, leg, and/or forearm are used to "bypass" the blockages (like a detour). Outcomes will be measured by comparing survival and improvement in quality-of-life.

Start Date: May 2023

open study

This phase III trial studies the side effects of inotuzumab ozogamicin and how well it works when given with frontline chemotherapy in treating patients with newly diagnosed B acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Chemotherapy drugs, such as [intervention], work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving inotuzumab ozogamicin with chemotherapy may work better in treating young adults with B acute lymphoblastic leukemia.

The goal of this clinical trial is to conduct a randomized controlled trial (RCT) to test the feasibility of two dose- and time-matched pain management programs, delivered via live video, for adults with chronic (lasting at least 3 months) and non-arthritic hip-related pain (HRP). Following pre-determined benchmarks, findings from this trial will be used to assess the feasibility, credibility, and acceptability of both programs (HIPS-1, HIPS-2). In preparation for a future clinical trial powered to test efficacy, we will optimize the protocol for patient recruitment, study protocol, and fidelity materials.

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.

Start Date: Oct 2025

open study

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.

This study is researching an experimental drug called ubamatamab, also referred to as "study drug". The study is focused on participants who have advanced ovarian cancer. The aim of the study is to see how safe, tolerable, and effective the study drug is on its own and in combination with other anti-cancer drugs (bevacizumab, cemiplimab, fianlimab, REGN10597 and a standard chemotherapy drug, pegylated liposomal doxorubicin [PLD]), referred to as "combination drugs'. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug and its experimental combinations - How much study drug and fianlimab is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects) and its combinations

The National Liver Cancer Screening Trial is an adaptive randomized phase IV Trial comparing ultrasound-based versus biomarker-based screening in 5500 patients with cirrhosis from any etiology or patients with chronic hepatitis B infection. Eligible patients will be randomized in a 1:1 fashion to Arm A using semi-annual ultrasound and AFP-based screening or Arm B using semi-annual screening using GALAD alone. Randomization will be stratified by sex, enrolling site, Child Pugh class (A vs. B), and HCC etiology (viral vs. non-viral). Patients will be recruited from 15 sites (mix of tertiary care and large community health systems) over a 3-year period, and the primary endpoint of the phase IV trial, reduction in late-stage HCC, will be assessed after 5.5 years.

Fibromyalgia is a debilitating chronic pain disorder. Based on prior research with MDMA, it can be hypothesized MDMA-assisted therapy in fibromyalgia patients may increase the range of positive emotions, interpersonal trust, and heighten the state of empathic rapport that can lead to an enhanced patient-clinician interaction and to initiate reattribution processes targeting dysfunctional thoughts towards pain. Therapeutic alliance, i.e. a positive patient-clinician relationship, is already acknowledged as an essential component for MDMA-assisted therapy. Despite its importance, the patient-clinician interaction and the neuroscience supporting patient/clinician therapeutic alliance has received almost no attention in MDMA research. The investigators will examine the potential therapeutic benefit of MDMA-assisted therapy for fibromyalgia. Additionally, this study will also target secondary objectives including the investigation of the clinical and physiological response (i.e. brain-to-brain concordance) supporting enhanced patient-clinician therapeutic alliance in fibromyalgia patients. The study includes two Experimental Sessions of therapy with MDMA combined with neuroimaging, along integrative therapy, baseline neuroimaging, and a 3 month follow up.
