Researchers are evaluating two different methods of pacing the heart in patients with slow heart rates (bradycardia). This multi-center randomized controlled trial, called PROTECT-HF, aims to compare the standard right ventricular pacing approach with a newer physiological pacing technique, which includes His bundle and left bundle area pacing. The study will enroll 2600 patients to assess differences in outcomes related to heart function and survival. Participants will be randomly assigned to receive either right ventricular pacing or physiological pacing through pacemaker implantation. The physiological pacing method may involve His bundle pacing or left bundle pacing, with biventricular pacing used if these are not possible. Both treatments will be performed at participating centers, with patients and outcome assessors blinded to the treatment allocation. A subgroup of 500 patients will also take part in an optional echocardiographic sub-study to observe heart changes over 24 months. During the study, participants will be monitored from the time of consent for up to 78 months. Evaluations will occur at the start and every six months afterward to track mortality and heart failure-related health events. Researchers will gather data on heart function, treatment effects, and safety. The main analysis will consider all patients as originally assigned, and additional analysis will assess those who received the assigned treatment.

Researchers are investigating the drug bezuclastinib in an open-label, two-part Phase 2 study for patients with Advanced Systemic Mastocytosis (AdvSM), including Aggressive Systemic Mastocytosis (ASM), Systemic Mastocytosis with an Associated Hematologic Neoplasm (SM-AHN), and Mast Cell Leukemia (MCL). The study aims to evaluate the safety, effectiveness, and how the drug behaves in the body for these serious conditions. Bezuclastinib is given orally as tablets taken continuously in 28-day cycles. The study has two parts: Part I focuses on identifying safe and tolerable doses of bezuclastinib over 18 months, while Part II evaluates its effectiveness by measuring the objective response rate and confirming the relationship between drug exposure and response during another 18-month period. Participants will undergo assessments including clinical evaluations, laboratory tests, and monitoring of their disease status to determine treatment effects and safety. Researchers will track the drug's impact on the disease and patient health throughout the study, which involves continuous treatment and follow-up over the specified time frames.

This research aims to evaluate the effects of litifilimab (BIIB059), a monoclonal antibody, in adults with active subacute or chronic cutaneous lupus erythematosus (CLE), with or without systemic lupus erythematosus (SLE). Participants have active skin symptoms of CLE that have not improved with antimalarial therapy or had difficulties continuing that treatment. The study focuses on reducing skin disease activity using several scores including CLA-IGA-R and CLASI, while also assessing safety, immune response, and quality of life. Participants will be randomly assigned to receive either litifilimab or a placebo injection under the skin every four weeks during a 24-week double-blind period where neither participants nor researchers know which treatment is given. After this, all participants will receive litifilimab injections every four weeks for an additional 28 weeks. Those who complete the treatment may join a long-term extension study or enter a follow-up safety period lasting up to 24 weeks. Total participation may last up to 80 weeks. Throughout the study, researchers will monitor skin disease activity using the CLA-IGA-R erythema score and the CLASI-A activity score to see how many participants improve. They will also assess safety, tolerability, immune system effects, and participants' quality of life using questionnaires. These evaluations occur regularly during both treatment periods and follow-up to understand the impact of litifilimab on CLE symptoms and overall health.

Researchers are investigating new treatments for rheumatoid arthritis (RA), a condition where current therapies like methotrexate (MTX) may not fully control symptoms for many people. This Phase 2b study evaluates a medicine called tulisokibart to see if it can better reduce RA symptoms in individuals already taking MTX. The trial aims to determine if one or more doses of tulisokibart work better than a placebo, which looks like the medicine but contains no active drug. The study includes a 12-week period where participants receive either tulisokibart or a placebo by subcutaneous injection while continuing their MTX treatment, which can be given by injection or orally. Following this, there is a long-term extension lasting 116 weeks, composed of a 44-week main extension and a 72-week optional extension, to further assess the medication's effects and safety over time. Participants will undergo assessments to measure treatment response, including the American College of Rheumatology 20% response criteria at week 12 to gauge symptom improvement. Throughout the study, researchers will monitor for safety and effectiveness, with evaluations extending through the long-term extension periods, totaling over two years of participation.

Researchers are conducting a Phase I/II, multi-site, open-label study to evaluate the safety, effectiveness, and optimal dosing of the investigational treatments BNT323 combined with BNT327 in adults with advanced breast cancer. This includes those with hormone receptor-positive or negative types, HER2-positive, HER2-low, HER2-ultralow, HER2-null breast cancer, or triple-negative breast cancer. The study aims to understand how these treatments work alone and together in this patient population. The study has two parts: Part 1 involves dose escalation where participants with chemotherapy-pretreated advanced breast cancer receive BNT323 and BNT327 together to find the recommended Phase 2 dose. Part 2 is an expansion phase that tests the safety and effectiveness of the chosen dose, including randomized comparisons of combination therapy at different doses and monotherapies. Participants may be assigned to one of four treatment arms, with dosing administered via intravenous infusion. Participants will be monitored for dose-limiting toxicities during the first 21 days of treatment, as well as adverse events up to 90 days after the last dose. Tumor response will be assessed for up to 36 months. Evaluations include heart function tests, tumor imaging, safety assessments, and tracking of side effects. The study carefully monitors treatment safety, effectiveness, and participant health throughout the trial duration.

Researchers are evaluating a combination therapy using BNT324, a B7-H3 antibody-drug conjugate, with BNT327, a bispecific antibody targeting PD-L1 and VEGF, in people with advanced or relapsed small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). This two-part Phase Ib/II trial aims to find safe and effective dose levels and to assess the therapy's safety and clinical effects in different lung cancer groups, including treatment-nave and relapsed patients. The study uses a dose escalation design in Part 1 to establish two safe combination dose levels of BNT324 and BNT327. In Part 2, participants receive either the higher or lower recommended dose to determine the optimal dose for further study. Some groups are randomized to one of the two doses, while others receive the highest dose based on prior results. Both drugs are given by intravenous infusion during the treatment period. Participants undergo screening before starting treatment, followed by treatment and safety monitoring. Researchers track dose-limiting toxicities, adverse events, dose adjustments, and treatment discontinuations up to 90 days after treatment ends or until new anticancer therapy starts. They also evaluate objective response rates up to 87 months after the first dose. Ongoing survival follow-up is included to assess long-term outcomes and safety.

Researchers are evaluating the safety, tolerability, and therapeutic effects of a combination treatment using BNT113 and pembrolizumab compared to pembrolizumab alone for patients with unresectable recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) that is positive for human papillomavirus 16 (HPV16+) and expresses the PD-L1 protein with a combined positive score of 1 or higher. This Phase II/III trial includes patients whose cancer cannot be treated with local therapies and who have not received prior systemic anticancer therapy for their current disease condition. The trial consists of two parts. Part A is a non-randomized Safety Run-In Phase to confirm the safety and tolerability of BNT113 combined with pembrolizumab at the selected dose. Part B is a randomized phase that compares BNT113 plus pembrolizumab against pembrolizumab alone as first-line treatment. Patients in Part A continue their treatment without randomization. Treatments are given by intravenous injection or infusion, and patients may receive either combination therapy or monotherapy for up to 24 months. There is also an optional pre-screening phase to test tumor samples for HPV16 DNA and PD-L1 expression before entering the main trial. Participants undergo regular assessments including tumor measurements based on RECIST 1.1 criteria confirmed by independent review. Researchers monitor treatment-emergent adverse events for up to 27 months in Part A and evaluate overall survival and progression-free survival for up to 48 months in Part B. Tumor tissue samples are collected before treatment to confirm eligibility. The study involves ongoing safety monitoring and efficacy evaluations throughout the treatment and follow-up periods.

Researchers are investigating BGB-16673, a targeted protein degrader aimed at treating various B-cell cancers including marginal zone lymphoma, follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia, Waldenström macroglobulinemia, and diffuse large B-cell lymphoma. The study includes both Phase 1 and Phase 2 parts to determine safe and effective dosing and to evaluate the drug's response in patients. The trial is conducted under the new company name BeOne Medicines, previously known as BeiGene. The treatment involves oral administration of BGB-16673. Phase 1 focuses on dose escalation and safety expansion to identify the maximum tolerated dose and recommended dose for expansion over approximately 28 days to 3 years. Phase 2 includes expansion cohorts to assess overall response rates over about 3 years. Participants may have prior treatments including Bruton tyrosine kinase inhibitors and other anticancer therapies depending on their cancer type and study phase. Participants will be monitored closely with assessments of adverse events from the first dose until 30 days after the last dose or before starting new therapy, whichever comes first, for up to 47 weeks. The study measures tolerability, dosing recommendations, and treatment response. Eligibility assessments include performance status and measurable disease, with safety and response evaluations continuing through both phases for up to three years.

Researchers are evaluating AZD8421, a CDK2 inhibitor, alone and combined with other targeted anti-cancer drugs in female patients with ER+ HER2- advanced breast cancer and metastatic high-grade serous ovarian cancer. This Phase I/IIa study aims to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary effectiveness of AZD8421. The study includes patients previously treated with CDK4/6 inhibitors or platinum-based chemotherapy, focusing on those with progressing metastatic or locoregionally recurrent disease. The study includes two main parts: AZD8421 monotherapy and combination therapy. Monotherapy evaluates AZD8421 alone to find the recommended Phase II dose in patients with advanced breast or ovarian cancer. Combination therapy tests AZD8421 with a CDK4/6 inhibitor (abemaciclib, ribociclib, or palbociclib) and camizestrant, an oral SERD, in breast cancer patients previously treated with CDK4/6 inhibitors. Treatment safety and drug behavior are closely monitored throughout. Participants will undergo assessments for dose limiting toxicities and adverse events from treatment start through an approximately 18-month safety follow-up. Researchers will also monitor laboratory tests, vital signs, ECGs, and reasons for stopping AZD8421 due to toxicity. The study requires measurable or assessable tumor lesions and performance status evaluations, ensuring patients meet specific health criteria. Total participation duration includes treatment and extended safety monitoring.

Researchers are evaluating ALN-CFB, an experimental small interfering RNA drug, in adults with Paroxysmal Nocturnal Hemoglobinuria (PNH) who continue to have anemia despite treatment with a complement component C5 inhibitor. This randomized, double-blind, placebo-controlled Phase 1/2 study aims to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of ALN-CFB. The study also investigates the side effects of ALN-CFB and its impact on Complement Factor B protein levels in the blood. Participants will receive either ALN-CFB or a placebo, both administered according to the study protocol. The study includes an initial treatment period with dosing as defined by the protocol. Details about additional study parts will be described after analyzing data from the first part. The placebo is designed to look like the study drug but contains no active medication. During the study, participants will be closely monitored for treatment-emergent adverse events and their severity over a period of up to 365 days. Researchers will also measure blood levels of ALN-CFB and Complement Factor B. The total duration of participant involvement and further assessments will be guided by the protocol amendments following initial data analysis.
