Natural History of Depression, Bipolar Disorder and Suicide Risk

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.

Single vs. Dual Antiplatelet Therapy in Elderly or HBR Patients Undergoing Percutaneous Intervention With DCB (PICCOLETO IV-EPIC 38)

This international, multicenter, open-label, randomized clinical trial evaluates the safety and efficacy of single antiplatelet therapy (SAPT) compared to dual antiplatelet therapy (DAPT) in elderly or high bleeding risk patients undergoing percutaneous coronary intervention (PCI) with the latest generation drug-coated balloon (DCB). The study includes patients with stable or unstable coronary syndromes and aims to assess rates of ischemic and bleeding adverse events.

Investigation of the Antidepressant Effects of (2R,6R)-HNK, an Enhancer of Synaptic Glutamate Release, in Treatment-Resistant Depression

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...

Cognitive Outcomes After Dexmedetomidine Sedation in Cardiac Surgery Patients

Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.

Safety of SBRT With Anti-PD1 and Anti-IL-8 for the Treatment of Multiple Metastases in Advanced Solid Tumors and Melanoma

Nivolumab (and other agents affecting the anti-programmed death-1 \[anti-PD-1\] pathway) have demonstrated anti-tumor activity in multiple tumor types. Combinations of immune-oncology (IO) agents with complimentary mechanisms as well as radiation represent a promising strategy to improve response rates to immunotherapy and overcome resistance. In this phase I/Ib study, radiation will be used in combination with IO agents nivolumab and anti-IL-8 (BMS-986253) to assess toxicity by organ system and then assess the preliminary efficacy of the treatment regimen. In Part 1, the study will determine the safe doses of radiation by organ site in conjunction with nivolumab and BMS-986253. In Part 2, the treatment regimen will be investigated in melanoma, prioritizing acral melanoma, to describe the response rate to treatment as well as other clinical and safety outcomes. The study will also provide the opportunity to evaluate changes in the tumor microenvironment induced by the treatment.

Sacubitril/Valsartan in PriMAry preventIoN of the Cardiotoxicity of Systematic breaST canceR trEAtMent (MAINSTREAM)

Breast cancer is the most commonly cancer in women in the overall global population. According to the World Cancer Research Fund International, there were more than 2.25 million new cases of breast cancer in women in 2020. Although the modern treatment strategies, based on the complex care, which consists of surgery, radiotherapy, hormone therapy, and targeted chemotherapy directed at specific cancer molecules have substantially reduced the risk of death due to breast cancer, their wide adoption results in the wider prevalence of cardiotoxicity, defined as either symptomatic heart failure, or asymptomatic contractile dysfunction. The occurrence of cardiotoxicity induced by anti-cancer therapies is estimated at 5-15%, and its development is the primary cause of therapy termination, which significantly reduces the probability of the efficacy of treatment. Several attempts have been made to determine the efficacious preventive strategy, which could diminish the risk of cancer-therapy induced cardiotoxicity. The results of the prior studies indicated a trend towards lower risk of troponin elevation, or left ventricular contractile dysfunction with the introduction of drugs interfering with the renin-angiotensin-aldosterone (RAA) axis, which constitute the primary treatment modality in heart failure with reduced ejection fraction (HFrEF). Sacubitril/valsartan, the novel therapeutic agent, has been demonstrated to significantly improve prognosis in patients with HFrEF. Prior retrospective, small, single-center studies have shown that treatment with sacubitril/valsartan may reduce the risk of cancer-therapy induced cardiotoxicity, or reverse contractile dysfunction caused by anti-cancer therapy. However, no large randomized data confirmed these findings. Therefore, the Sacubitril/Valsartan in PriMAry preventIoN of the cardiotoxicity of systematic breaST canceR trEAtMent) study, has been designed to verify, whether the preventive use of sacubitril/valsartan administered in the doses recommended in patients with HFrEF in breast cancer patients undergoing adjuvant chemotherapy with anthracyclines or anthracyclines and HER-2 monoclonal antibodies, will reduce the incidence of cardiotoxicity defined as impaired left ventricular systolic function on transthoracic echocardiography (TTE). In the trial, a total of 480 patients with histologically confirmed breast cancer, who are eligible for chemotherapy with anthracyclines or anthracyclines and HER-2 monoclonal antibodies, will undergo 1:1 randomization to either preventive treatment with sacubitril/valsartan or placebo. The patients will be followed for 24 months, and will have repetitive efficacy and safety examinations, including echocardiography, MRI (optionally), electrocardiography including 24-h Holter monitoring, blood tests, functional capacity tests and quality of life assessment.
