Researchers are evaluating the safety and effectiveness of bomedemstat (MK-3543) compared with the best available therapy (BAT) in adults with essential thrombocythemia (ET) who have not responded well to or cannot tolerate hydroxyurea. This phase 3 clinical trial aims to determine if bomedemstat provides a better durable clinicohematologic response in these participants. Participants will receive either bomedemstat as an oral capsule or one of the best available therapies, including anagrelide (oral capsule), busulfan (oral tablet), interferon alfa or its pegylated forms (subcutaneous solution), or ruxolitinib (oral tablet). The study involves a randomized, open-label design where treatments are compared directly. Throughout the study, participants will be monitored for their hematologic response up to about 52 weeks. Assessments include platelet and neutrophil counts before starting treatment to ensure eligibility. Safety and efficacy are tracked to evaluate the long-term impact of the treatments on ET.

Researchers are evaluating nemtabrutinib compared with the investigator's choice of ibrutinib or acalabrutinib in adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have not received any prior therapy. This Phase 3 study aims to determine if nemtabrutinib is not worse than ibrutinib or acalabrutinib in terms of objective response rate and if it is better regarding progression-free survival, both assessed using standardized disease criteria by independent review. Participants will be randomly assigned to receive one of the three oral treatments: nemtabrutinib, ibrutinib, or acalabrutinib. The study compares the effectiveness of nemtabrutinib against the other two drugs chosen by the investigator to treat first-line CLL/SLL. Treatment continues with monitoring over months to assess response and disease progression. During the study, participants will undergo evaluations based on the International Workshop on Chronic Lymphocytic Leukemia criteria, including blinded independent central reviews of their disease status. Researchers will track objective response rates up to about 33 months and progression-free survival up to around 104 months. Participants will also be monitored for safety and treatment adherence throughout the trial period.

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.

Researchers are evaluating the effectiveness of iberdomide maintenance therapy compared to lenalidomide maintenance therapy after autologous stem cell transplantation (ASCT) in adults with newly diagnosed multiple myeloma. This phase 3 study aims to determine which maintenance treatment better supports patients following their initial transplant and induction therapies. Participants must have responded to prior treatments and undergone ASCT within specified time frames. Participants will receive either iberdomide or lenalidomide at specified doses on scheduled days as maintenance therapy after their ASCT. The study is randomized, multi-center, and open-label, meaning both participants and researchers know which treatment is given. The treatments will be administered following a standard induction therapy including proteasome inhibitors, immunomodulatory drugs, and possibly monoclonal antibodies, with or without consolidation after transplant. Throughout the study, participants will be monitored for progression-free survival for up to 6 years to assess how well the maintenance therapies prevent disease progression. Researchers will also evaluate safety and treatment response according to established myeloma criteria. Regular assessments will include clinical evaluations and monitoring for any signs of disease relapse or adverse effects over the long term.

Researchers are evaluating whether avoiding further axillary treatment after neoadjuvant chemotherapy (NACT) is as effective as standard axillary treatment for patients with early stage breast cancer who initially had cancer in the lymph nodes confirmed by needle biopsy but show no residual cancer in the lymph nodes after NACT. The study aims to determine if skipping axillary lymph node dissection (ALND) or axillary radiotherapy (ART) affects disease free survival (DFS) and whether it reduces the risk of lymphoedema five years after treatment. This phase 3, open-label, randomized trial includes patients with T1-3N1M0 breast cancer and confirmed nodal metastases who have undergone sentinel node biopsy removing at least three lymph nodes post-NACT.

Researchers are evaluating the safety and effectiveness of nemtabrutinib (formerly ARQ 531) in adults with various blood cancers including chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Richter's transformation, marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), follicular lymphoma (FL), and Waldenström's macroglobulinemia (WM). This Phase 2 study is designed to better understand how well nemtabrutinib works and how safe it is for these conditions. The study is conducted in two parts: Part 1 focuses on dose escalation and confirmation to find the recommended Phase 2 dose, while Part 2 involves expanding the study to include eight disease-specific groups. Participants receive nemtabrutinib tablets once daily by mouth. Different cohorts in Part 2 are defined based on specific diagnoses and prior treatments, such as those with relapsed or refractory disease after certain therapies. Each participant will receive treatment according to their cohort's criteria. Participants will be closely monitored throughout the study, with assessments including the number of participants experiencing dose-limiting toxicities and adverse events, response rates according to established lymphoma criteria, and treatment discontinuations due to side effects. The study includes detailed evaluations like biopsies for biomarker analysis, imaging scans, and laboratory tests. Safety and treatment effects will be followed for up to several years, allowing researchers to gather comprehensive data on nemtabrutinib's impact.

Researchers are evaluating whether adding navtemadlin to ruxolitinib treatment provides more clinical benefit than ruxolitinib alone for patients with Myelofibrosis who have not responded well to ruxolitinib alone. This Phase 3, randomized, double-blind study focuses on patients with Primary Myelofibrosis, Post-Polycythemia Vera Myelofibrosis, or Post-Essential Thrombocythemia Myelofibrosis. Participants must be JAK inhibitor-naive and have a suboptimal response to ruxolitinib treatment during the initial run-in period. During the study, all subjects start by receiving ruxolitinib alone in a run-in period. Those showing a suboptimal response are then randomly assigned in a 2:1 ratio to receive either navtemadlin or a navtemadlin placebo as an add-on to their ongoing ruxolitinib treatment. The study is blinded, so neither the participants nor the doctors know who is receiving the navtemadlin or placebo. Navtemadlin is an investigational MDM2 inhibitor, while ruxolitinib is a janus kinase 1/2 inhibitor. Participants are involved in assessments to compare spleen volume reduction and total symptom score reduction between the two treatment groups over 24 weeks. Researchers monitor safety and efficacy through clinical evaluations, symptom tracking, and laboratory tests. The study includes screening for performance status, blast counts, and TP53 wild-type status, ensuring participants meet specific health criteria before randomization.

The primary objective of the study is to compare radiographic progression-free survival (rPFS) in participants who receive 177Lu-TLX591 with SOC to rPFS in participants who receive SOC only. This study consists of three Parts: * Part 1: Safety and Dosimetry Lead-in, * Part 2: Randomized Treatment Expansion, and * Part 3: Long-term Follow-up The study will commence with a 30-patient safety and dosimetry lead-in (Part 1) and proceed to a randomization treatment expansion in approximately 490 patients (Part 2). Patients in Part 2 will be randomized in a 2:1 ratio to receive either 177Lu-TLX591 + Standard of Care SoC (Group A), or SoC alone (Arm B). SoC in this trial is either: ARPI (enzalutamide or abiraterone) or docetaxel. All patients will be followed in long-term follow-up for at least 5 years from the first therapeutic dose, death, or loss to follow up (Part 3). Only patients that meet PSMA-positivity criteria per Blinded Independent Central Review (BICR) will be eligible for this study.
