Researchers are evaluating the Spinal Stabilization Technologies PerQdisc Nucleus Replacement System in patients with degenerative disc disease (DDD) affecting one or more lumbar discs, specifically between L1 and S1. This prospective, open-label, multi-center study aims to collect additional safety and effectiveness data for this minimally invasive device. The PerQdisc Nucleus Replacement Device (NRD) is designed to replace a damaged nucleus pulposus surgically, with the goal of reducing chronic low back pain by preserving disc height and maintaining spinal range of motion, offering an alternative to spinal fusion surgery. Participants will undergo nucleus replacement surgery with the PerQdisc device using standard anterior, lateral, or minimally invasive posterolateral surgical approaches. The study includes 72 patients and requires approval by a Medical Advisory Board before surgery. The device replaces the damaged disc material and is intended for single-level treatment. The study does not involve a comparison group but focuses on evaluating the device's performance and safety. During the study, participants will be assessed using the Oswestry Disability Index (ODI) and Visual Analog Scale (VAS) for low back pain at 6 and 12 months post-treatment. Safety will be monitored by tracking device expulsion and failure over the same periods. Participants will also undergo various evaluations, including imaging and clinical assessments, to ensure appropriate eligibility and monitor outcomes. The total follow-up period includes assessments up to 12 months after surgery to evaluate both the device's effectiveness and safety profile.

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 evaluating new treatments for people with high-risk non-muscle invasive bladder cancer (HR NMIBC), a type of bladder cancer that has not spread to the muscle but has a high chance of worsening or returning. This cancer type may include carcinoma in situ (CIS), which is a flat, surface-level bladder cancer. The study aims to learn whether adding intismeran autogene (V940), a treatment designed to boost the immune system's attack on cancer, to the standard Bacillus Calmette-Guerin (BCG) immunotherapy can help people live longer without the cancer growing, spreading, or coming back. Participants will receive either the combination of V940 with BCG or BCG alone. BCG is given as a bladder instillation, while V940 is given as an intramuscular injection. The study is phase 2, open-label, and randomized. As of a 2026 amendment, outcome measures for a monotherapy arm of V940 are no longer primary or secondary. Treatment is focused on Cohort A, which includes people with high-risk non-muscle invasive bladder cancer who are BCG-naïve or meet specific recurrence criteria. During the study, participants will be monitored for event-free survival for up to approximately 5 years. Researchers will assess how long participants live without the cancer worsening or returning. The study includes regular evaluations, imaging, and safety monitoring. The total duration of participation depends on individual outcomes and follow-up but includes long-term observation to assess treatment effects and safety.

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 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 evaluating treatments for breast cancer that is hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-), specifically in cases where the cancer is either locally advanced and cannot be removed by surgery or has spread to other parts of the body (metastatic). The study aims to determine if patritumab deruxtecan (also called HER3-DXd or MK-1022) helps patients live longer overall or without the cancer growing compared to chemotherapy or trastuzumab deruxtecan. This is a Phase 3 clinical trial focusing on this particular type of breast cancer. Participants receive one of several treatments: patritumab deruxtecan through intravenous infusion, chemotherapy options like paclitaxel or nab-paclitaxel via IV, oral capecitabine tablets, liposomal doxorubicin via IV, or trastuzumab deruxtecan via IV infusion. The study compares the effects of patritumab deruxtecan alone to the treatment chosen by the physician. Treatments are administered according to standard dosing schedules during the trial. During the study, participants are monitored for how long they live without the cancer progressing (up to about 45 months) and overall survival (up to about 85 months). Researchers assess disease status through imaging and other evaluations. Participants have regular check-ups to monitor health, treatment effects, and any side effects. The study tracks treatment response and safety over the extended follow-up period to understand the benefits and risks of the therapies.

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 effectiveness, safety, and tolerability of subcutaneous ianalumab in adults with diffuse cutaneous systemic sclerosis. This Phase 2 study compares ianalumab with a placebo in participants diagnosed according to established classification criteria, focusing on those with active disease and specific autoantibodies. The goal is to better understand ianalumab's impact on this condition over a long treatment period. The study includes several phases: up to 6 weeks for screening, followed by a 52-week initial treatment period where participants receive either ianalumab or placebo by subcutaneous injection. After this, there is a second 52-week open-label treatment period where all participants receive ianalumab. Finally, a post-treatment follow-up period lasts at least 20 weeks and can extend up to 2 years after the last dose. Participants will undergo various assessments throughout the study, including evaluations of their skin condition using the rCRISS25 response at week 52. Safety and tolerability will also be closely monitored. The study involves regular visits for clinical evaluations, laboratory tests, and monitoring of disease activity and antibody status, with the total participation potentially lasting over two years including follow-up.

Researchers are evaluating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of RO7507062 in adults with systemic lupus erythematosus (SLE). This is a Phase 1, first-in-human study with two parts: Part 1 involves single ascending doses to find the appropriate dose, and Part 2 involves dose escalation using fractionated dosing. Tocilizumab may also be used by investigators if needed to manage cytokine release syndrome during the study. Participants will receive RO7507062 as a subcutaneous injection according to their assigned treatment arm. Tocilizumab solution for infusion may be given intravenously at 8 mg/kg for participants weighing 30 kg or more, or at 12 mg/kg for those under 30 kg if clinically required. The study consists of a dose-finding period followed by a dose escalation period with fractionated doses, with safety evaluations extending through these phases. During the study, participants will be monitored for dose-limiting adverse events from day 1 through day 29 in Part 1 and through the 28-day safety evaluation in Part 2. Adverse events will be tracked for up to approximately 12 months. The study includes assessments of safety, drug levels, and effects on disease activity. Participants will undergo clinical evaluations and laboratory tests throughout their involvement, which includes the treatment and follow-up periods.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab as first-line treatments for patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors have high PD-L1 expression. This Phase III, randomized, double-blind, and global study focuses on participants with stage IV mNSCLC who do not have certain genetic mutations or rearrangements and are eligible for systemic therapy. Participants receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two biological treatments given as monotherapy. Both groups will be monitored over time to assess treatment impact and safety. Throughout the study, participants undergo evaluations including tumor measurements by CT or MRI, performance status assessments, and organ function tests. Researchers will measure overall survival and progression-free survival for up to approximately five years. Tumor samples are collected before treatment for central testing, and participants’ health and treatment responses are closely followed during the trial period.
