Researchers are investigating CGT9486, also known as bezuclastinib, in an open-label Phase 2 study for patients with Advanced Systemic Mastocytosis AdvSM. This includes those diagnosed with 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, pharmacokinetics, and pharmacodynamics of bezuclastinib in this patient population. Participants will receive bezuclastinib tablets orally, taken continuously in 28-day cycles. The study is divided into two parts Part I focuses on identifying effective and tolerable dosing exposures over 18 months, while Part II evaluates the drugs efficacy by measuring objective response rates and confirming the exposure-response relationship, also over 18 months. Additional assessments include effects on mutation allele burden, serum tryptase levels, histopathologic changes, spleen and liver volume, and safety monitoring. During the study, participants will undergo various clinical evaluations, including laboratory tests, imaging to monitor organ size changes, and assessments of disease response and progression. Researchers will track adverse events and pharmacokinetic profiles throughout the 18 months. The study involves continuous monitoring of participants to understand the treatments impact on survival and disease progression over this period.

Researchers are evaluating the combination of CGT9486 and sunitinib compared to sunitinib alone in patients with locally advanced, unresectable, or metastatic Gastrointestinal Stromal Tumors GIST. This Phase 3, open-label international trial involves multiple parts, including dose confirmation, drug interaction assessments, and efficacy comparisons. The study also includes substudies focusing on drug-drug interaction potential and first-line treatment in patients with specific genetic mutations KIT exon 9. Approximately 482 patients will participate across these parts.

Researchers are evaluating a combination treatment for men with prostate cancer that has spread to other parts of the body and continued to grow despite treatments that lower male hormones. This phase I trial compares the effects of a radioactive drug called lutetium Lu 177 177Lu-PSMA-617 alone and combined with a vaccine therapy called Sipuleucel-T. The goal is to see if the combination can better stimulate the immune system and control the cancer. Participants are randomly assigned to one of two groups. One group receives 177Lu-PSMA-617 intravenously every 6 weeks for up to 6 cycles, while the other group receives the same radioactive drug plus Sipuleucel-T starting at week 8, given every 2 weeks for up to 3 doses. Both groups undergo various imaging scans such as PETCT, bone scans, MRI, and blood tests to monitor response and safety throughout the study. During the trial, patients have blood samples taken and may undergo leukapheresis removal of certain blood cells for vaccine preparation. They are followed closely with scans and clinical visits during treatment and after completion. Follow-up visits occur at 30 days, then every 3 months for up to a year, and every 6 months until disease progression. Researchers measure immune response, safety, tumor response, progression-free survival, and overall survival over up to 3 years of observation.

Researchers are evaluating the safety, side effects, best dose, and effectiveness of a combination conditioning treatment for donor stem cell transplantation in patients with high-risk acute myeloid leukemia AML, acute lymphoblastic leukemia ALL, and myelodysplastic syndrome MDS. This phase I trial studies a targeted radioimmunotherapy drug, 225Ac-DOTA-Anti-CD38 daratumumab, combined with chemotherapy drugs fludarabine and melphalan, and total marrow and lymphoid irradiation TMLI. Daratumumab targets CD38 on cancer and immune cells, potentially helping the immune system to attack cancer cells. Participants receive daratumumab intravenously followed by indium In 111-DOTA-daratumumab and actinium Ac 225-DOTA-daratumumab on day -15. Total marrow and lymphoid irradiation is given twice daily from days -8 to -5, fludarabine is given intravenously on days -4 to -2, and melphalan on day -2. On day 0, participants undergo hematopoietic cell transplantation HCT. Graft-versus-host disease GVHD prevention with sirolimus and tacrolimus starts on day -1. Throughout the study, participants undergo various scans, biopsies, and blood tests to monitor treatment effects and safety. Participants are monitored closely after transplantation with visits twice weekly for the first 100 days, then twice monthly up to six months, and monthly thereafter until immunosuppressive therapy is stopped without GVHD signs. Yearly follow-up continues for two years. Assessments include adverse events, survival rates, relapse, graft-versus-host disease incidence, infections, blood cell recovery, organ function, and drug distribution. The study aims to determine the maximum tolerated dose and evaluate overall safety and effectiveness of the treatment combination.

Researchers are evaluating the imaging agent 64Cu-LNTH-1363S in patients with sarcomas or gastrointestinal tract GIT cancers to assess its safety, determine the best imaging dose and timing, and compare the imaging results with fibroblast activation protein FAP expression in tumor samples. This Phase 12a open-label study is divided into two parts and aims to better understand how this radiolabeled agent behaves in the body and how well it highlights tumors that express FAP. In Part 1, six patients with metastatic sarcomas will receive a fixed dose of 64Cu-LNTH-1363S to evaluate its distribution, radiation dose, and optimal imaging window during a one-day intervention, followed by a safety follow-up. In Part 2, approximately 20 patients with non-metastatic, operable sarcomas or GIT cancers scheduled for surgery will receive the optimal dose determined in Part 1 to study the correlation between imaging results and tissue FAP expression. Both parts include detailed cardiac monitoring to assess any changes in heart activity related to the agent. Participants will undergo screening before receiving the imaging agent, followed by serial PETCT scans at multiple timepoints on the intervention day to measure biodistribution and image quality. Tissue samples collected during surgery will be analyzed to compare with imaging findings. Safety and tolerability will be monitored through follow-up visits, ECGs, and phone contact. The total study duration varies from about three weeks for Part 1 to up to 11 weeks for Part 2, including surgery and post-surgery sample collection.

Researchers are evaluating the safety, side effects, and best dose of a new drug called 8-chloroadenosine combined with venetoclax in patients with acute myeloid leukemia AML that has returned or not responded to previous treatment. This phase 1 trial aims to understand how well this combination works to block cancer growth and prevent relapse in these patients. The study also explores the biological effects of the treatment and identifies markers related to response and resistance. Participants receive 8-chloroadenosine intravenously over 4 hours daily for five days, along with venetoclax taken orally once daily for 28 days. This treatment cycle repeats every 28 days for up to four cycles, unless the disease worsens or side effects become unacceptable. After completing the treatment cycles, patients are followed for up to one year with regular check-ups every 28 days to monitor their health and response. During the study, participants undergo assessments to track adverse events, dose-limiting toxicities, and treatment responses such as remission rates and survival outcomes. Researchers also measure drug levels in the blood and analyze gene and metabolic changes associated with the therapy. Follow-up visits continue for up to one year to evaluate the duration of remission, overall survival, and event-free survival, ensuring thorough monitoring of patient safety and treatment effects.

Researchers are evaluating a blended e-health intervention designed to reduce fear of progression FOP in women with advanced gynecologic or breast cancer. This trial focuses on whether a combination of remote group sessions and online activities can help women manage their fear of cancer worsening, which is a common and distressing concern. The study aims to assess the feasibility and acceptability of this approach alongside its effects on FOP and related psychological symptoms such as distress and anxiety. Participants are randomly assigned to one of two groups for a 6-week program. The Mindful Living Program group attends three 60-minute group sessions during weeks 1, 3, and 6 and completes online sessions in weeks 2, 4, and 5. They practice mindfulness and coping skills daily for 10-12 minutes, receive a check-in call around week 3 or 4, and have access to supportive online resources. The comparison group participates in the Navigating Cancer Program with a similar schedule of group and online sessions plus a check-in call but without the daily mindfulness practice or additional online tools. During the study, participants complete questionnaires measuring fear of progression, distress, anxiety, mindfulness, and other psychological outcomes at the start, after 6 weeks, and at 12 weeks follow-up. Researchers monitor attendance, engagement, and usability of the intervention over 6 weeks and conduct follow-up assessments at week 12. The total participation time includes the 6-week intervention period plus follow-up, with safety and usability being key measures.

Researchers are studying metastatic castration-resistant prostate cancer mCRPC to find new treatment options. This trial evaluates if the study medicine ifinatamab deruxtecan I-DXd or MK-2400 helps people live longer overall and experience slower cancer growth or spread compared to chemotherapy. The study is a Phase 3 trial comparing I-DXd with standard chemotherapy for mCRPC patients. Participants are randomly assigned to receive either I-DXd at 12 mgkg every 3 weeks through intravenous infusion or docetaxel chemotherapy at 75 mgm2 every 3 weeks combined with daily prednisone pills. Treatment continues until the disease progresses, unacceptable side effects occur, or treatment is stopped for other reasons. Premedication is given before each dose of I-DXd to help prevent nausea and vomiting. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess overall survival and radiographic progression-free survival for up to about 36 months. Additional measures include response rates, time to pain progression, PSA progression, and adverse events. The study tracks safety, treatment effects, and quality of life over a long follow-up period to better understand the potential benefits and risks of I-DXd compared to chemotherapy.

Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma GCB DLBCL, a fast-growing blood cancer affecting immature B-cells. The study compares two treatment combinations to see if more people respond to zilovertamab vedotin MK-2140 plus R-CHP versus polatuzumab vedotin plus R-CHP. This Phase 2 trial aims to assess the effectiveness and safety of these regimens in participants with newly diagnosed GCB DLBCL. Participants receive either zilovertamab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone R-CHP, or polatuzumab vedotin combined with R-CHP. Treatments are given by intravenous infusion on Day 1 of each 3-week cycle for up to 6 cycles, approximately 4 months, with prednisone or prednisolone taken orally for 5 days of each cycle. For participants with high-risk DLBCL, up to 2 additional cycles of rituximab or biosimilar are given. During the study, participants are monitored for response to treatment using Lugano Response Criteria, with follow-up lasting up to about 31 months for the primary outcome. Secondary outcomes include progression-free survival, overall survival, event-free survival, duration of complete response, adverse events, and quality of life assessments. Safety and health status are regularly checked through exams, lab tests, and questionnaires over several years, with total study participation extending up to 7 years.

Researchers are evaluating a culturally-tailored home-based physical activity program designed for Hispanic or LatinoLatina adolescent and young adult childhood cancer survivors. These survivors may face long-term effects like weight gain, fatigue, and reduced physical fitness after cancer treatment. The study aims to see if this culturally-relevant program can help increase physical activity and improve overall health compared to using a Fitbit tracker alone. The study has two stages. In Stage 1, 20 Latinx survivors participate in developing the intervention using Fitbit trackers, text messages, social media support, wearable activity devices, and interviews over 9 months. In Stage 2, 170 survivors who do not meet physical activity guidelines are randomized to either the intervention group, which includes Fitbit use, weekly goal-setting, peer support via social media and Zoom meetings, and optional activity partners, or a control group that only uses Fitbit trackers for 12 weeks. The intervention includes an intensive phase with weekly sessions followed by a 4-week maintenance phase. Participants will wear Fitbit trackers daily and engage in goal-setting, peer discussions, and physical activity reminders. Researchers will measure moderate to vigorous physical activity, sedentary time, and health-related quality of life over 12 weeks. Additional evaluations include physiological markers of heart and metabolic health and qualitative interviews to improve the program. The study lasts through the intervention phases with ongoing monitoring and support for participants.
