OKI-219-101 is a Phase 1a/1b, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PDx), and efficacy of OKI-219 as monotherapy and in combination with other anti-cancer drugs. Phase 1a (Part A) will investigate escalating doses of OKI-219 monotherapy, and Phase 1b will investigate OKI-219 (at a tolerated dose determined in Part A) in combination with fulvestrant (Part B), trastuzumab and tucatinib (Part C), atirmociclib (Part D), and ribociclib and fulvestrant (Part E). Participants will continue to receive study treatment until disease progression, intolerable toxicity, or other study treatment withdrawal criteria are met.

The goal of this study is to see whether kisspeptin, a naturally occurring hormone, can stimulate the release of other reproductive hormones in men and women with idiopathic hypogonadotropic hypogonadism (IHH). The investigators are also examining whether kisspeptin can help women release eggs from their ovaries. Kisspeptin will be administered SC for two weeks in a pulsatile fashion. Ultrasound monitoring of ovarian follicular growth (for women) and frequent blood sampling (every 10 minutes for up to 70 minutes) will be performed to assess the physiologic response to kisspeptin over time.

Repetitive transcranial magnetic stimulation (rTMS) is a way of non-invasively stimulating specific brain networks and is an established treatment for Major Depressive Disorder (MDD). This proposal will reveal network mechanisms of the therapeutic effects of rTMS by investigating how stimulating each network specifically changes network connectivity and behavior. This will be done in a highly individualized manner in depressed and healthy patients, leading to more effective and more individualized treatments for depression.

The study is researching an experimental drug called REGN5837 in combination with another experimental drug, odronextamab (called "study drugs"). The aim of the study is to see how safe and tolerable the study drugs are, and to define the recommended dose for phase 2. The study is looking at several other research questions, including: - What side effects may happen from taking the study drugs - How much study drug is in the blood at different times - Whether the body makes antibodies against the study drugs (that could make the drugs less effective or could lead to side effects) - To find out how well the study drugs work against relapsed or refractory aggressive B-cell non-Hodgkin lymphomas (B-NHLs)

RADIANT is a network of 14 clinical sites and several laboratories dedicated to the study of atypical diabetes. The objective of this study is to define new forms of diabetes and the unique mechanisms underlying these forms of atypical diabetes. The specific aims are to: 1. Identify and enroll individuals and families with undiagnosed rare and atypical forms of diabetes. 2. Determine the etiologic basis of the metabolic disorder among individuals and families with novel forms of rare and atypical diabetes. 3. Understand the pathophysiology of individuals and families with novel forms of rare and atypical forms of diabetes.

Purpose: About 6.4% of the U.S. population suffers from posttraumatic stress disorder (PTSD). Trauma-focused psychotherapies are generally effective in PTSD, but responses vary greatly across individuals and PTSD subpopulations. Neurobiological factors impacted by life experiences, stress, and genetics can affect treatment responses. These factors can alter brain capacities needed to reprocess traumatic memories prevent them from triggering intensely distressing, disruptive, out-of-place responses. For example, during psychotherapy for PTSD, trauma memory activation engages two competing brain processes that affect recovery: "extinction" versus "reconsolidation" of trauma-related emotional, physiological, and behavioral responses. This study tests whether a single intravenous (IV) dose of allopregnanolone (Allo) compared to placebo (which is non-active): promotes consolidation of extinction learning (sub-study 1) or blocks reconsolidation of physiological responses triggered by aversive memories (sub-study 2). The study also tests whether Allo compared to placebo affects retention of non-aversive memories.

The TSC Biosample Repository collects and stores samples of blood, DNA, and tissues that scientists can request to use in their research. The samples we collect are all linked to clinical data in the TSC Natural History Database. The TSC Natural History Database captures clinical data to document the impact of the disease on a person's health over his or her lifetime. This data may be collected retrospectively or prospectively.
