Approximately 482 patients will participate across these parts.

Researchers are evaluating new medicines to prevent HIV-1 Human Immunodeficiency Virus Type 1 infection. This Phase 3 clinical study aims to determine if taking the drug MK-8527 once a month can prevent HIV-1 infection as well as or better than the standard daily pre-exposure prophylaxis PrEP. The study also assesses the safety and tolerance of MK-8527 in participants. Participants are randomly assigned to one of two groups. One group receives 11 mg of MK-8527 once monthly along with a daily placebo pill matching FTCTDF. The other group receives a daily dose of FTC245 mg TDF and a monthly placebo matching MK-8527. This treatment period lasts for approximately two years, followed by an additional 28-day period where all participants receive open-label FTCTDF daily. During the study, participants will undergo regular monitoring to check for HIV-1 infection and any adverse events. Researchers will track the number of participants who acquire HIV-1, experience side effects, or stop treatment due to side effects over the two-year period. Safety and adherence assessments will be conducted to evaluate the study treatments. The total participation time includes the two-year treatment phase plus the 28-day follow-up with open-label FTCTDF.

Researchers are investigating new treatments for metastatic cervical cancer, which is cancer that has spread beyond the cervix, the lower part of the uterus. This study evaluates the safety and effectiveness of the antibody drug conjugate sacituzumab tirumotecan sac-TMT combined with pembrolizumab and bevacizumab. The goal is to find out if these treatments, given together or with some variations, help patients live longer or delay cancer progression compared to standard care. The study has two parts. In Part 1, participants receive sac-TMT, pembrolizumab, and bevacizumab together to assess safety. In Part 2, all participants first get standard induction treatment with pembrolizumab, paclitaxel, and cisplatin or carboplatin, possibly with bevacizumab. Those whose cancer does not worsen then enter maintenance treatment, where they are randomly assigned to receive either pembrolizumab alone or sac-TMT plus pembrolizumab, with optional bevacizumab. Participants are involved for up to about 20 months during maintenance treatment after up to 4 months of induction. The study monitors safety by tracking side effects and treatment discontinuations. Effectiveness is measured by progression-free survival and overall survival up to several years. Quality of life and physical functioning are also assessed through questionnaires. Treatments and evaluations occur through regular intravenous infusions and periodic monitoring visits.

Researchers are investigating new treatments for high-risk, early-stage breast cancer, specifically targeting two types triple-negative breast cancer TNBC and hormone receptor-low positiveHER2-negative breast cancer. These cancers are characterized by low or no HER2 protein and low hormone receptor presence. The study aims to evaluate if adding sacituzumab tirumotecan sac-TMT to pembrolizumab and chemotherapy can better reduce cancer cells in tumors and lymph nodes and improve the length of time patients live without cancer progression compared to pembrolizumab with chemotherapy alone. Participants in this trial receive one of two treatment plans. One group gets sacituzumab tirumotecan intravenously every two weeks plus pembrolizumab every three weeks for 12 weeks, followed by pembrolizumab with carboplatin and paclitaxel for another 12 weeks. After 3 to 6 weeks, surgery and optional radiation therapy take place, followed by pembrolizumab for about 28 weeks. Participants with remaining disease may receive additional treatments chosen by their doctors, including olaparib, capecitabine, doxorubicin, epirubicin, or cyclophosphamide. The other group receives chemotherapy drugs carboplatin and paclitaxel with pembrolizumab initially, then pembrolizumab with cyclophosphamide and doxorubicin or epirubicin, followed by surgery, optional radiation, and pembrolizumab for about 28 weeks, with similar additional options for residual disease. During the study, participants undergo core needle biopsies, receive intravenous infusions of study drugs, and have surgery and possible radiation therapy. Researchers assess outcomes such as the percentage of participants with no detectable cancer cells at surgery pathological complete response, event-free survival up to about 92 months, and overall survival up to nearly 10 years. Quality of life and side effects are monitored through questionnaires and adverse event tracking. The study lasts several years, with various assessments throughout treatment and follow-up periods to gather comprehensive data on treatment effects and safety.

Researchers are investigating new treatments for radiographic axial spondyloarthritis r-axSpA, a form of arthritis causing pain, stiffness, and swelling in the spine and pelvis joints. This condition shows visible damage on X-rays. The study aims to evaluate if different doses of the medicine tulisokibart can improve r-axSpA symptoms compared to a placebo, which helps measure the medicines effects accurately. Participants will be assigned to one of several groups receiving high, medium, or low doses of tulisokibart, or a placebo. The study includes a 16-week placebo-controlled phase. After that, participants receiving the low dose or placebo will be re-assigned to medium or high doses. Following this, there is a long-term extension lasting 124 weeks, which has a 40-week main extension and an 84-week optional extension, allowing continued treatment and observation. Throughout the study, participants will have regular assessments to monitor symptoms and disease activity using various indexes and imaging scores. Researchers will track the percentage of participants who achieve improvement at week 16 and monitor safety by recording adverse events up to approximately 154 weeks. The study uses injections of tulisokibart or placebo under the skin and includes ongoing evaluations of physical function, pain, inflammation, and quality of life.

Researchers are evaluating the safety, tolerability, and therapeutic effects of BNT113 combined with pembrolizumab compared to pembrolizumab alone as a first-line treatment for patients with unresectable recurrent or metastatic head and neck squamous cell carcinoma HNSCC positive for human papilloma virus 16 HPV16 and expressing the protein PD-L1 with a combined positive score of 1 or higher. This is an open-label, multi-site, Phase IIIII clinical trial consisting of two parts an initial safety run-in phase and a randomized phase. In the safety run-in phase Part A, patients receive BNT113 in combination with pembrolizumab to confirm safety and tolerability at selected dose levels. The randomized phase Part B compares BNT113 combined with pembrolizumab against pembrolizumab monotherapy. Treatments are given by intravenous injection or infusion and continue for up to 24 months. An optional pre-screening phase allows tumor samples to be tested for HPV16 DNA and PD-L1 expression before the main trial screening. Participants will be closely monitored throughout the study. Assessments include safety evaluations, tumor response, and survival outcomes such as overall survival and progression-free survival. Tumor tissue samples must be provided for testing. Researchers will measure treatment-emergent adverse events, response rates, duration of response, and disease control. The study may last up to 48 months, with ongoing safety and efficacy monitoring during and after treatment.

Researchers are evaluating whether combining HIV-specific broadly neutralizing antibodies bNAbs with antiretroviral therapy ART in adults newly diagnosed with acute HIV infection AHI is safe and can delay viral rebound compared to ART alone. This phase II, randomized, double-blind, placebo-controlled study aims to assess the impact of this combination on viral load, immune response, and viral reservoirs. The study is sponsored by the National Institute of Allergy and Infectious Diseases NIAID. Participants are randomly assigned to receive either a combination of two bNAbs, VRC07-523LS and PGT121.414.LS, given as intravenous infusions once at study entry alongside daily oral ART, or a placebo infusion with daily ART. The study involves several steps, including treatment initiation, analytic treatment interruption, and monitoring phases. The bNAbs are administered intravenously at specific doses over 15 to 60 minutes at enrollment. ART consists of a daily oral tablet containing bictegravir, emtricitabine, and tenofovir alafenamide. During the study, participants attend scheduled visits for safety assessments, blood tests measuring viral load and immune cells, and monitoring for side effects or adverse events. Researchers track the time to viral rebound after stopping ART, changes in immune cell counts, and drug levels in the blood. Participants who meet criteria for restarting ART will do so and continue to be monitored. The total participation includes treatment and follow-up periods, with close observation to evaluate safety and treatment effects up to 24 weeks after ART interruption.

Researchers are evaluating the efficacy and safety of volrustomig compared to observation in participants with unresected locally advanced head and neck squamous cell carcinoma LA-HNSCC who have not progressed after receiving definitive concurrent chemoradiotherapy cCRT. This phase III, randomized, open-label global study aims to assess whether volrustomig can improve outcomes in this patient population. Participants are randomly assigned to one of two groups those who receive volrustomig as sequential therapy, and those who undergo observation without additional treatment. The study compares these two approaches following prior curative concurrent chemoradiotherapy. The trial includes long-term follow-up to monitor patient outcomes. During the study, participants will be regularly assessed for progression-free survival, overall survival, physical functioning, and quality of life. Researchers will also monitor for the presence of anti-drug antibodies and adverse events related to volrustomig. Follow-up evaluations may continue for up to approximately eight years to fully understand the treatment impact and safety profile.

Researchers are evaluating the efficacy and safety of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced Stage III, unresectable non-small cell lung cancer NSCLC whose disease has not progressed after definitive platinum-based concurrent chemoradiotherapy cCRT. This Phase III, randomized, double-blind, placebo-controlled, international study aims to provide new insights into treatment options for this patient population. Participants will receive either durvalumab and domvanalimab or durvalumab plus placebo as intravenous infusions every four weeks, beginning on Day 1 and continuing for up to 12 months. The study includes two groups one receiving the combination of durvalumab and domvanalimab, and the other receiving durvalumab with a placebo. Both treatments are given through infusion to assess their effects on disease progression and safety. During the trial, participants will undergo regular assessments including monitoring progression-free survival for up to 8 years after randomization. Other measures include overall survival, response rates, duration of response, and various time-to-event outcomes related to disease progression and symptom deterioration. Researchers will also evaluate drug concentrations and immune responses approximately 12 weeks after the last dose. Participants can expect scheduled visits for infusions and evaluations as part of this long-term study.

Researchers are evaluating the long-term safety and effectiveness of Afimkibart also known as RO7790121 in adults with Atopic Dermatitis who participated in earlier Afimkibart clinical trials. This Phase 2 extension study focuses on participants who previously responded to Afimkibart treatment, aiming to gather extended data over several years. Participants will receive Afimkibart through subcutaneous injections according to a schedule outlined in the study protocol. The study is non-randomized and involves parallel groups, with all participants receiving the active drug. The treatment and follow-up periods can last up to six years to assess long-term outcomes. Throughout the study, participants will undergo regular assessments including the Eczema Area and Severity Index EASI, Investigator Global Assessment IGA, patient questionnaires on eczema symptoms and quality of life POEM and DLQI, and blood tests to measure drug levels and immune response. Researchers will monitor adverse events and antibody development against Afimkibart. Participation involves ongoing evaluations and monitoring over the extended study duration.
