Researchers are evaluating (Z)-endoxifen as a potential treatment for premenopausal women with estrogen receptor-positive (ER+) and HER2-negative breast cancer. This phase 2 open-label study includes two parts: a pharmacokinetic (PK) phase to understand how the body processes the drug and a treatment phase to assess the drug's effects on tumor growth. The study aims to see if (Z)-endoxifen can slow or stop tumor growth by measuring changes in a biomarker called Ki-67. Participants are premenopausal women who meet specific cancer and health criteria. Participants in the PK part will take (Z)-endoxifen capsules daily at varying doses (20 mg, 40 mg, or 80 mg). Some will also receive a monthly injection of goserelin, a drug that temporarily stops estrogen production in the ovaries. The treatment cohort will receive both (Z)-endoxifen and goserelin. Tumor tissue samples will be collected by breast biopsy after about 4 weeks to assess the Ki-67 biomarker. Participants showing tumor response may continue treatment for up to 24 weeks or until they undergo surgery. Throughout the study, participants will have blood draws to measure drug levels and tumor markers, breast biopsies, imaging scans, and safety assessments. The main outcomes include measuring (Z)-endoxifen levels after 4 weeks, the rate of Ki-67 reduction, and tumor response after 24 weeks. Study participation lasts up to 6 months, including treatment, surgery, and a follow-up visit one month after surgery.

Researchers are evaluating the use of 3'-deoxy-3'-[18F] fluorothymidine (FLT) PET imaging to study tumor growth and DNA synthesis activity in patients with various cancers, including brain tumors, leukemia, lymphoma, and solid tumors. This phase I trial aims to see how well FLT PET imaging can detect cancer lesions, measure tumor proliferation, and estimate patients' responses to treatment. Participants receive up to four FLT PET imaging sessions. During each session, a small amount of the tracer compound [F-18] FLT is injected into the veins in a saline solution. PET scan data collection begins immediately and continues for two hours to measure tumor growth. Blood samples may be taken during each scan, and urine samples are collected afterward to analyze how the tracer breaks down. Throughout the study, participants undergo multiple imaging procedures to monitor tumor activity. Researchers measure tracer uptake and retention in tumors and normal tissues and assess changes in related enzymes and uptake values before and after therapy. Participants must be able to lie still during scans and meet certain physical and reproductive health criteria. The study includes safety precautions such as pregnancy testing and contraception requirements for fertile patients.

Researchers are evaluating MDNA11, a long-acting "beta-only" recombinant interleukin-2 designed to activate immune cells that attack cancer while minimizing stimulation of cells that suppress immunity. This Phase 1/2 open-label study aims to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and early anti-tumor activity of MDNA11 alone or combined with pembrolizumab in patients with advanced or metastatic solid tumors. The study includes dose-escalation and dose-expansion parts for both monotherapy and combination therapy with pembrolizumab. MDNA11 is given intravenously every two weeks with doses ranging from 0.003 to 0.6 mg/kg for monotherapy, while dose ranges for combination therapy are also evaluated. Treatment continues until progression, withdrawal, or loss to follow-up, with tumor assessments by CT or MRI every 8 weeks. Participants will undergo regular imaging scans every 8 weeks to monitor tumor response and safety assessments throughout the 24-month study. Researchers will track recommended doses for expansion, treatment-related adverse events, and overall safety. The study involves up to 115 patients across multiple sites and includes long-term monitoring for up to 24 months.

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 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 a combination treatment using BNT326 and BNT327 in adults with advanced or metastatic non-small cell lung cancer (NSCLC), including those with relapsed, progressive, or treatment-nafve disease. This multi-site, open-label study includes dose-finding and dose-expansion phases to investigate the safety, tolerability, and preliminary effectiveness of this combination therapy. The study targets patients whose tumors are advanced, metastatic, or recurrent with no curative treatment options available and includes participants with different genomic alterations. The study is divided into several parts: Part 1 is a dose escalation phase to find safe dose levels of BNT326 with BNT327; Part 2a expands the dose to further evaluate safety and initial efficacy; Part 2b focuses on dose optimization and understanding the contributions of each component. Participants receive intravenous infusions of BNT326 and BNT327, with some cohorts possibly receiving additional treatments such as pembrolizumab or standard chemotherapy. Treatment continues until disease progression, unacceptable side effects, withdrawal, or a maximum of 24 months. Dose levels for certain cohorts are determined based on earlier phase data, and some parts include randomization to different treatment groups. Participants undergo a screening period before starting treatment, followed by treatment, safety follow-up, efficacy follow-up, and long-term survival monitoring, totaling about 36 months. Researchers assess dose-limiting toxicities within the first 21 days of treatment and monitor adverse events, treatment interruptions, and objective response rates up to 36 months. Tumor measurements, safety labs, imaging, and patient health status are regularly evaluated. The study tracks tolerability and efficacy while ensuring participant safety throughout treatment and follow-up.

Researchers are evaluating two surgical approaches, radical prostatectomy (RP) and precision prostatectomy (PP), in men with low- and intermediate-risk prostate cancer. RP is the standard treatment that removes the entire prostate and surrounding tissue but often leads to significant side effects like erectile dysfunction and urinary incontinence. PP is a newer technique designed to preserve important nerves and tissues to improve functional outcomes while still removing more than 90% of prostate tissue. This trial aims to assess whether PP can provide better recovery of sexual and urinary function without compromising cancer control compared to RP. The trial randomly assigns eligible participants to receive either RP or PP surgery. RP involves complete removal of the prostate and nearby tissues, whereas PP spares some prostate tissue and nerves important for continence and erectile function. Both surgeries follow similar procedures without extra time or equipment, and the study compares their effects on patient outcomes. Patients are followed for 12 months after surgery to track recovery and cancer control. Participants will be assessed before surgery, at 3 months, and at 12 months after surgery for sexual health and urinary control. Researchers use questionnaires like the Sexual Health Inventory for Men (SHIM) and record the number of daily pads used for continence. They also monitor if any secondary prostate cancer treatments are needed within 12 months. The study will provide important information on how these surgeries affect quality of life and cancer outcomes over a full year.

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 the safety and feasibility of using bone marrow from deceased donors for allogeneic transplantation in adults with various blood cancers, including acute and chronic leukemias, myelodysplastic syndrome, and certain types of lymphoma. This first-in-human study involves patients receiving either a strong myeloablative or a milder reduced intensity conditioning regimen before transplant. The study is conducted in phases 1 and 2 and aims to assess safety outcomes over a 56-day period, with follow-up continuing for one year. Participants will receive hematopoietic cell transplantation using Ossium HPC Marrow from donors who are partially or fully HLA matched. Before the transplant, patients undergo either one of two myeloablative regimens or one of two reduced intensity regimens. After the transplant, patients receive post-transplant care as part of the treatment plan. The study includes carefully selected conditioning regimens tailored to the patient's condition and matching status. During the study, participants are closely monitored for important outcomes such as neutrophil engraftment by day 28, serious adverse events, and severe adverse events within 56 days, including those related to the bone marrow infusion. Deaths within 56 days are also recorded. Participants undergo regular assessments including bone marrow evaluations, PET/CT imaging, and laboratory tests to check organ function and overall health. Researchers track treatment effects and safety throughout the study and during the one-year follow-up period to better understand the transplant's impact.
