Researchers are evaluating the safety, tolerability, and effectiveness of CYB003, a Deuterated Psilocin Analog, compared to a placebo when added to current antidepressant treatment in adults with moderate to severe Major Depressive Disorder (MDD). This Phase III trial focuses on participants aged 18 to 85 years who have had inadequate response to a stable antidepressant dose, aiming to better understand how CYB003 might improve depressive symptoms. Participants receive oral doses of CYB003 or matching placebo along with manualized psychological support provided by trained facilitators. The treatment period includes multiple dosing sessions with monitoring and assessments throughout. Placebo is used as a comparator to evaluate the combined safety and efficacy of CYB003 in this population. During the study, participants undergo evaluations using the Montgomery-Åsberg Depression Rating Scale (MADRS) at several time points, including screening, baseline, and multiple days up to the end of treatment at Day 42. Researchers monitor symptoms, side effects, and overall safety. Participants provide informed consent and are assessed regularly to track changes in depression severity and any adverse events over the course of the study.

Researchers are evaluating a 6-month community walking program called the 10,000 Step Club (10KSC) for people with Parkinson's disease (PD) and their caregivers in Las Vegas, Nevada. The program aims to reduce sedentary behavior, fear of falling, loneliness, and social isolation among participants. It is designed to encourage people with PD to increase their physical activity, foster social connections, and collectively work toward a goal of 10,000 steps per day. The program will be offered in English and Spanish and targets recruitment of 60 participants with PD diagnosed by a neurologist. The intervention involves three walking groups meeting weekly in local parks across Las Vegas, especially in areas with fewer PD exercise programs and higher proportions of underserved populations. Each group walk lasts 60 minutes and uses Nordic walking poles to promote stability, upright posture, and full-body movement. Participants are encouraged to attend at least one walking session per week but may join additional groups on other days. Step counts will be tracked in real-time using step watches provided to all participants. An incentive program will motivate and recognize achievements toward reaching the step goals. Participants will be monitored throughout the 6-month program with assessments including daily step count averages, fear of falling avoidance behavior, social isolation, loneliness, and self-efficacy. Physical therapy students from the University of Nevada, Las Vegas will lead and supervise the walking groups. The program emphasizes safety, feasibility, and effectiveness while encouraging participants to engage regularly and build physical activity habits. Participation is free, and caregivers are welcome to join alongside people with PD.

Researchers are investigating the effects of XYOSTED as a testosterone replacement therapy in adolescent males aged 12 to under 18 years who have primary or secondary hypogonadism. This Phase 3/4, open-label, multicenter study aims to evaluate how well XYOSTED supports puberty continuation or induction, as well as its dosage, safety, and testosterone level outcomes. Participants have a confirmed deficiency or absence of endogenous testosterone and will be assessed for pubertal development and hormone levels before starting treatment. Participants will receive XYOSTED injections with dosages tailored to their weight and targeted Tanner Stage of puberty. Dose adjustments will be made regularly based on serum total testosterone levels measured at specific intervals after dosing, with evaluations approximately every three months to reach desired testosterone levels. After completing the 52-week primary study, participants may join a 24-month long-term safety extension with clinic visits every six months for ongoing clinical, laboratory, and pharmacokinetic assessments. During the study, participants will undergo thorough clinical examinations including pubertal staging, multiple testosterone measurements, and monitoring for safety and pharmacokinetics throughout treatment and extension periods. Researchers will track changes in testosterone levels from enrollment through week 53 and monitor overall safety. The study includes detailed follow-up and dose management to support pubertal development and assess long-term effects of XYOSTED therapy in this population.

Researchers are evaluating the safety, how the body processes, and effects on body weight of the investigational drug CRB-913 in participants with obesity. This Phase 1b study includes two parts: Part 1 focuses on healthy adults to measure drug levels in the blood after a single dose, while Part 2 involves obese participants to assess safety and weight effects using different doses compared to placebo. Part 2 is blinded so that participants, doctors, and the sponsor do not know who receives the drug or placebo. In Part 1, healthy adults receive a single dose of CRB-913 tablets to study how much of the drug enters the bloodstream and how long it stays. In Part 2, obese participants take one of three doses of CRB-913 or placebo once daily for 12 weeks. After treatment ends, participants are monitored for 28 days. The study includes a randomized, double-blind, placebo-controlled design for Part 2. Participants will attend study visits for drug administration, safety assessments, and blood tests to measure drug levels and effects on body weight. Researchers will monitor for side effects and adverse events from the first dose through 28 days after final dosing. The total participation time includes the 12-week treatment period plus the 28-day follow-up phase to evaluate safety and drug behavior in the body.

Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation (CIC) in this 26-week phase 3 study. The study is randomized, double-blind, and placebo-controlled, involving multiple centers. It aims to compare three doses of tenapanor (5 mg, 25 mg, and 50 mg taken twice daily) against a placebo, with a focus on improving spontaneous bowel movements. Participants will first undergo a 2-week screening where their eligibility is assessed through medical history, physical exams, lab tests, ECG, and self-reported constipation symptoms using an electronic diary (eDiary). Eligible patients will then be randomly assigned to receive one of the three doses of tenapanor or placebo twice daily for 26 weeks. During this treatment period, patients will continue daily and weekly symptom reporting via the eDiary and attend regular safety visits at weeks 2, 4, 8, 12, 16, 20, and 26. After completing the 26-week treatment, patients enter a 4-week treatment-free safety follow-up period to monitor any adverse events. A final visit occurs at the end of this follow-up to assess safety. The main outcome measured is the durable complete spontaneous bowel movements response over 12 weeks. Overall, the study involves careful monitoring of symptoms, safety, and treatment effects over approximately 32 weeks.

Researchers are evaluating the use of aglatimagene besadenovec combined with valacyclovir in men with localized, intermediate-risk prostate cancer who are planning to undergo external beam radiation therapy (EBRT). This phase 2a, open-label, multi-center study aims to understand how the treatment spreads in the body and its impact on immune system markers. The study focuses on men with intermediate-risk prostate cancer and compares a treatment group receiving the gene therapy plus valacyclovir alongside EBRT to a control group receiving EBRT alone. Participants in the treatment group will receive three intraprostatic injections of aglatimagene besadenovec, a genetically modified virus carrying a specific gene, administered either through the rectum or perineum. Each injection is followed by a 14-day course of oral valacyclovir. EBRT will begin after the second injection. The control group will receive standard or moderately hypofractionated prostate-only EBRT without the gene therapy. Biospecimens such as blood, urine, and semen will be collected at specific times before and after injections to track the presence of the virus and measure immune responses. Participants will be monitored closely throughout the study. Researchers will regularly evaluate safety by tracking adverse events and laboratory tests. The main outcome measured is the biodistribution of aglatimagene besadenovec up to three months after the last injection. Immune system activation markers, viral shedding in various body fluids, and tumor-related proteins will also be assessed. The study involves approximately 45 men divided between the treatment and control groups, with continuous safety monitoring during and after treatment.

Researchers are studying whether calderasib alone or combined with cetuximab can treat advanced solid tumors in people who have the KRAS G12C mutation. This phase 2, open-label trial aims to find out how many participants respond to these treatments and to compare their safety and tolerability. Participants receive calderasib by mouth and cetuximab through intravenous infusion. The study includes people with locally advanced or metastatic solid tumors other than colorectal cancer, who have already undergone standard treatments. The trial monitors response and side effects over time as participants receive either calderasib alone or in combination with cetuximab. During the study, participants undergo regular assessments to measure tumor response and track any side effects or adverse events. Researchers record how many people experience treatment-related side effects and how many stop treatment due to these effects. The study follows participants for up to approximately 76 months to assess long-term outcomes and safety.

Researchers are studying a medicine called enlicitide to reduce low-density lipoprotein cholesterol (LDL-C) in adults with high cholesterol (hyperlipidemia). This trial aims to find out if taking enlicitide together with rosuvastatin, a standard cholesterol-lowering drug, works better than a placebo in lowering LDL-C levels. The study is a Phase 3 trial that is randomized, double-blind, and placebo-controlled to ensure accurate and unbiased results. Participants will receive oral tablets of enlicitide or placebo along with oral capsules of rosuvastatin or placebo. The study compares the effect of enlicitide plus rosuvastatin against placebo to evaluate their impact on LDL-C. The treatment period lasts 8 weeks, during which participants take their assigned medications as directed. During the study, researchers will measure the average percent change in LDL-C from the start of the trial to week 8. Participants will be monitored for safety and any side effects throughout the study. The total participation time includes screening, treatment, and follow-up assessments to evaluate the medicines' effects and safety in adults aged 18 to 64 with hyperlipidemia.

Researchers are evaluating molnupiravir, a study medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 more effectively than a placebo. This Phase 3 randomized, placebo-controlled, double-blind study focuses on non-hospitalized adults at high risk of severe disease progression due to COVID-19. The study addresses the need for alternative treatments for people who cannot take certain COVID-19 medications due to availability or potential drug interactions. Participants will receive either molnupiravir or a placebo, both given orally as two 400 mg film-coated tablets every 12 hours for 5 days, totaling 10 doses. Some participants may also receive remdesivir as part of standard care if clinically appropriate and available. The study compares the effects of molnupiravir with placebo in preventing severe illness outcomes. Throughout the study, participants will be monitored for outcomes such as hospitalization, death, or medically attended visits related to COVID-19 up to 29 days. Safety is assessed by tracking adverse events for up to about 5 months and discontinuation of study treatment due to adverse events for about 5 days. The study involves laboratory tests, symptom assessments, and safety evaluations to understand molnupiravir's impact on disease progression and participant health.

Researchers are investigating new treatments for metastatic cervical cancer, which is cancer that has spread from the cervix to other parts of the body. This Phase 3 study aims to evaluate the safety and effectiveness of combining sacituzumab tirumotecan (sac-TMT), an antibody drug that targets cancer cells, with pembrolizumab and bevacizumab. The study seeks to find out if this combination can help people live longer or keep their cancer from worsening compared to standard treatments. The study has two parts. In Part 1, participants receive sac-TMT together with pembrolizumab and bevacizumab to assess safety. In Part 2, after standard initial treatment, those whose cancer does not progress will be randomly assigned to maintenance treatment with either pembrolizumab alone or sac-TMT plus pembrolizumab. Bevacizumab may be added during maintenance treatment based on the doctor's decision. All treatments are given through intravenous infusions, and participants may receive rescue medications to manage side effects before sac-TMT infusion. Participants will be monitored for adverse events and treatment tolerability over several months. The study measures include progression-free survival and overall survival, assessed by independent review. Safety and treatment continuation rates are tracked during Part 1 for up to approximately 66-69 months, while Part 2 outcome measures extend up to 48-60 months. Various assessments, including laboratory tests and evaluations of cancer status, will be performed throughout the study to understand treatment effects and participant well-being.
