Researchers are evaluating a new treatment called ifinatamab deruxtecan (I-DXd) for men with metastatic castration-resistant prostate cancer (mCRPC). This study compares I-DXd to chemotherapy to see if it helps people live longer overall and live longer without their cancer worsening. It is a Phase 3, open-label trial focused on patients who have progressed on prior therapies and have evidence of metastatic disease. Participants receive either I-DXd through an intravenous infusion every 3 weeks or docetaxel chemotherapy administered every 3 weeks. Prednisone tablets are also given daily as part of the treatment plan. Before each I-DXd dose, premedication is provided to help prevent nausea and vomiting using a combination of drugs such as corticosteroids and anti-nausea medicines. Treatment continues until disease progression, unacceptable side effects, or other reasons to stop. During the study, researchers monitor overall survival and how long patients live without their cancer progressing, for up to about 36 months. Participants undergo tumor tissue collection, scans, and assessments to track disease status and side effects. Safety is closely watched throughout treatment. The study includes men aged 18 and older with confirmed prostate cancer and metastatic disease who have previously received certain hormone therapies but no prior taxane chemotherapy for mCRPC.

Researchers are studying a new treatment for HIV-1 infection that combines two medicines, islatravir and ulonivirine, taken once weekly. The goal is to see if this new study treatment works as well as the standard antiretroviral therapy (ART), which usually involves taking up to three medicines once or twice daily. This research also aims to learn about the safety and tolerability of the study treatment compared to the standard ART. The study compares the once-weekly combination of islatravir and ulonivirine with the standard daily treatment of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). Participants will take either the study drugs or the standard drugs for 96 weeks. Some participants may receive matching placebos as part of the study design. The treatment is given orally as capsules or tablets according to the assigned group. Participants will be monitored throughout the study with regular assessments, including measuring the amount of HIV-1 virus in the blood to see if it is suppressed below 50 copies/mL at weeks 24 and 48. The study will also track any side effects or adverse events and whether participants stop the treatment due to these events. Overall, the study lasts about 96 weeks, with ongoing safety and effectiveness evaluations to understand how well the treatments work and how safe they are over time.

Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection. The goals of this study are to learn: * If taking MK-8527 once a month works to prevent HIV-1 infection as well as or better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day * About the safety of MK-8527 and if people tolerate it

Researchers are investigating new treatments for people with high-risk, early-stage breast cancer, specifically targeting triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/HER2-negative breast cancer. These types have little or no HER2 protein and involve hormones like estrogen or progesterone. The study aims to evaluate if the addition of sacituzumab tirumotecan (sac-TMT), a targeted therapy, combined with pembrolizumab and chemotherapy can improve outcomes compared to pembrolizumab with chemotherapy alone. Participants receive treatments including sacituzumab tirumotecan, pembrolizumab, and chemotherapy drugs such as carboplatin and paclitaxel, all given by intravenous infusion. Rescue medications like antihistamines, acetaminophen, dexamethasone, or steroid mouthwash may be used as needed. The study is randomized and open-label, comparing sac-TMT followed by chemotherapy plus pembrolizumab to chemotherapy and pembrolizumab without sac-TMT. During the study, researchers will monitor participants up to about 30 weeks to assess the percentage of people with no remaining cancer cells at surgery. They will also follow participants for up to approximately 92 months to track event-free survival, meaning time without cancer growth, spread, or return. Participants will undergo imaging, clinical assessments, and laboratory tests to evaluate treatment effects and safety throughout the study.

Researchers are evaluating the safety and effectiveness of a new topical treatment called APT-001 (spinosad 1.8%) in patients with blepharitis, an inflammation of the eyelids. This Phase 2, randomized, controlled, double-blind study compares APT-001 with a vehicle control to determine its ability to clear eyelid collarettes, which are a sign of the condition. The study aims to confirm that the treatment is safe and well tolerated by patients. Participants will receive either APT-001 topical ophthalmic ointment or a matching vehicle control, both administered once daily. The treatment period lasts from Day 1 to Day 43. The main goal is to measure cure based on eyelid collarette count from the start of treatment to the end at 6 weeks. During the study, participants will attend multiple visits for monitoring and assessments. Researchers will track eyelid collarette counts and watch for any adverse effects related to the treatment. Safety evaluations and efficacy measurements will be conducted throughout the study to ensure participant well-being and to determine the treatment's impact on blepharitis.

Researchers are evaluating the effectiveness and safety of opevesostat combined with hormone replacement therapy compared to alternative treatments with abiraterone acetate or enzalutamide in people with metastatic castration-resistant prostate cancer (mCRPC) who have already been treated with one next-generation hormonal agent. This Phase 3 study aims to determine whether opevesostat improves radiographic progression-free survival, assessed by independent central review, in participants with or without androgen receptor ligand binding domain mutations. Participants will receive either oral opevesostat along with hormone replacement therapy drugs such as dexamethasone and fludrocortisone acetate, or they will receive alternative oral treatments including abiraterone acetate with prednisone acetate or enzalutamide. Hydrocortisone can be used as a rescue drug if needed. The study is open-label and randomized, comparing these treatment strategies in participants who have progressed after prior hormonal therapy. During the study, participants will undergo assessments including imaging scans to monitor disease progression. Researchers will measure radiographic progression-free survival up to approximately 52 months. Safety and overall survival are also monitored as secondary outcomes. Participants must attend scheduled visits for evaluations, provide tumor tissue samples, and have ongoing monitoring of organ function, hormone levels, and other relevant health parameters throughout the study period.

This research aims to evaluate the safety and effectiveness of zilovertamab vedotin (ZV) combined with standard treatments for participants with relapsed or refractory diffuse large B-cell lymphoma (rrDLBCL). It is a Phase 2/3, randomized, open-label, multisite study including participants aged 18 and older. The study tests two main hypotheses: that ZV combined with rituximab, gemcitabine, and oxaliplatin (R-GemOx) is better than R-GemOx alone for progression-free survival; and that ZV combined with bendamustine rituximab (BR) is better than BR alone. However, enrollment in the BR and ZV + BR arms is discontinued, so no outcome analysis will be done for those groups. The study is split into two parts: Part 1 confirms the dose of ZV, and Part 2 expands to evaluate its efficacy. Participants receive intravenous infusions of ZV at various doses, along with standard drugs including rituximab, gemcitabine, oxaliplatin, and bendamustine as appropriate. Prophylactic granulocyte colony-stimulating factor (G-CSF) is given with each ZV cycle according to institutional guidelines. Treatment schedules and doses are carefully managed to assess safety and treatment effects. During the study, participants will be monitored for dose-limiting toxicities up to about 6 weeks, and adverse events for up to approximately 68 months. Researchers will also track treatment discontinuations due to adverse events. Key outcomes include overall survival and progression-free survival up to about 35 months. Participants will have regular assessments including scans, clinical evaluations, and laboratory tests to measure response and monitor safety throughout their participation.

Hidradenitis suppurativa (HS) is a chronic and often painful skin disease that causes lumps, abscesses, and scars in areas like under the breasts, armpits, inner thighs, groin, and buttocks. Researchers are evaluating the investigational drug lutikizumab compared to placebo in adults and adolescents with moderate to severe HS. This study aims to assess the disease activity and safety of lutikizumab in a Phase 3 clinical trial involving about 1280 participants worldwide.

Researchers are evaluating the effectiveness and safety of Afimkibart (RO7790121) as both an induction and maintenance treatment for people with moderately to severely active Crohn's disease in this Phase III, multicenter, double-blind, placebo-controlled study. The goal is to understand how well Afimkibart works compared to placebo in managing symptoms and disease activity over time. Participants will receive either Afimkibart or a matching placebo. Afimkibart is given both as an intravenous infusion and as a subcutaneous injection. This treat-through study means participants continue on the assigned treatment throughout the study period, allowing evaluation of both initial and ongoing therapy effects. During the study, participants will be regularly assessed to measure clinical remission using the Crohn's Disease Activity Index (CDAI) and to check for endoscopic response at week 52. Researchers will monitor safety and treatment effects throughout, with the entire participation lasting up to one year. Assessments include clinical evaluations and endoscopic examinations to track disease changes and treatment impact.

This is a Phase III, randomized, open-label multicenter study that will evaluate the efficacy and safety of giredestrant compared with fulvestrant, both in combination with the investigator's choice of a CDK4/6 inhibitor (palbociclib, ribociclib or abemaciclib), in participants with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer who have developed resistance to adjuvant endocrine therapy.
