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 safety and effectiveness of elenestinib BLU-263 combined with symptom directed therapy SDT compared to placebo plus SDT in adults with indolent systemic mastocytosis ISM whose symptoms are not well controlled by SDT alone. This randomized, double-blind, placebo-controlled Phase 23 study includes multiple parts to assess different doses and durations of elenestinib treatment, including an open-label extension for participants finishing earlier phases. The study also enrolls participants who have previously received an approved selective KIT inhibitor and includes pharmacokinetic groups. Participants receive oral elenestinib or placebo once daily alongside SDT, which is personalized based on individual symptom management needs. Part 1 focuses on short-term treatment lasting up to 12 weeks, while Part 2 extends treatment to approximately 48 weeks. Part 3 and other parts allow treatment for up to about 5 years. The study monitors participants through these phases to evaluate how elenestinib affects symptoms, disease markers, and safety over time. During the study, participants undergo regular assessments of symptoms using the ISM-Symptom Assessment Form ISM-SAF, laboratory tests including serum tryptase and KIT D816V allele levels, bone marrow evaluations, and quality of life measures. Researchers track adverse events and changes in disease-related factors at various points up to 5 years. This thorough monitoring helps measure treatment effects and safety over both short and long-term periods, with total participation lasting several years depending on the study part.

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 investigating new treatment options for meningiomas that continue to grow despite local therapies like surgery or radiotherapy. This trial focuses on evaluating a precision medicine approach that combines PET-based imaging to select patients with tumors expressing somatostatin receptors and a targeted radioligand therapy called 177Lu-DOTATATE. This is the first randomized clinical trial studying this therapy in patients with meningiomas that have not responded to other treatments. Participants will be randomly assigned to one of two groups. One group receives 177Lu-DOTATATE through intravenous infusions every four weeks for a total of four cycles. The other group receives local standard care, which may include treatments like hydroxyurea, bevacizumab, sunitinib, octreotide, everolimus, or observation with supportive care, based on the investigators choice. This study is designed to compare the effects of 177Lu-DOTATATE against various standard treatments in this patient population. During the study, participants will undergo regular MRI scans to measure tumor size and progression. Researchers will also assess overall survival, neurological function, quality of life, and treatment side effects over a period extending up to two years after enrollment. Monitoring includes imaging, laboratory tests, and health questionnaires to evaluate how the disease and treatments affect participants over time.

The LuDO-N Trial is a phase II multi-center clinical study investigating the use of 177Lu-DOTATATE in children with recurrent or relapsed high-risk neuroblastoma. This trial aims to assess how well this treatment works by measuring the response at 1 and 4 months after treatment ends. Secondary goals include evaluating survival rates, treatment-related side effects, and examining how tumor characteristics relate to treatment response. Participants receive two doses of 177Lu-DOTATATE administered intravenously, with at least two weeks between doses. The first dose is based on the patients weight, while the second dose is adjusted using scans to control radiation exposure, particularly to avoid kidney toxicity. Patients must be prepared for autologous stem cell transplantation as part of this intensified treatment approach. During the study, participants will undergo various scans and laboratory tests before starting treatment and at scheduled times to monitor tumor response and side effects. Researchers will assess treatment effectiveness using established neuroblastoma response criteria and will follow patients for up to five years to monitor survival and any long-term effects. The total participation time includes treatment administration and extended follow-up for safety and outcomes.

Researchers are evaluating calderasib alone or combined with cetuximab to treat people with advanced solid tumors that have the KRAS G12C mutation, excluding colorectal cancer. This study aims to measure how many participants experience tumor shrinkage or disappearance and compare the responses between the two treatments. It is a phase 2, open-label trial focused on treatment safety and tolerability. Participants will receive calderasib orally with no set limit on treatment cycles. Some participants will also receive cetuximab via intravenous infusion every two weeks. Treatment continues until criteria for stopping the study intervention are met. The trial uses a randomized, parallel design to compare the two experimental arms. Throughout the study, participants will be monitored for tumor response, adverse events, and treatment discontinuations related to side effects. Researchers will also assess progression-free survival, duration of response, and overall survival up to about 76 months. The trial lasts until April 2032, with ongoing safety and efficacy evaluations during this period.

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 the effectiveness and safety of an investigational drug called BNT323 also known as DB-1303 compared with standard chemotherapy in women with recurrent endometrial cancer. The study includes two groups based on the level of HER2 protein in the tumor Cohort 1 with HER2 levels 1 or 2 who have been previously treated with immune checkpoint inhibitors, and Cohort 2 with HER2 level 3. The study aims to understand how well BNT323 or chemotherapy controls cancer progression and how the drug affects patients immune response and quality of life. Participants in Cohort 1 will be randomly assigned to receive either BNT323 or chemotherapy drugs such as doxorubicin, paclitaxel, or docetaxel. In Cohort 2, participants will receive BNT323 alone. Treatments are given intravenously and continue until the cancer progresses, unacceptable side effects occur, or consent is withdrawn. The study includes screening, treatment, safety follow-up, efficacy follow-up, and a long-term survival follow-up lasting up to about 53 months. During the study, participants will undergo regular assessments including tumor evaluations, safety monitoring, and quality of life questionnaires. Researchers will measure progression-free survival in Cohort 1 and tumor response rate in Cohort 2. Safety is monitored by tracking adverse effects and drug levels in the body. Participants can expect to be followed for up to 53 months after treatment to assess long-term outcomes and survival.

Many patients receiving radiation therapy for head and neck cancer develop painful mouth sores called oral mucositis, causing severe pain that lasts through and beyond treatment. This study evaluates whether BupiZenge, a lozenge containing the long-acting pain reliever bupivacaine, provides better pain control than lidocaine solution. The trial aims to see if improved pain management with BupiZenge enhances quality of life and reduces opioid use in adults aged 18 to 80 with head and neck cancer undergoing radiotherapy. Participants are randomly assigned to receive either BupiZenge lozenges or lidocaine oral solution. BupiZenge is taken as one lozenge that dissolves slowly in the mouth with a dosing interval of at least 3 hours, up to 8 lozenges per day. Lidocaine is used as an oral solution held in the mouth, also every 3 hours as needed, with a maximum daily dose of 120 mL. The study includes a combined screening and run-in period up to five weeks, followed by treatment during radiotherapy and for up to six weeks total if pain and sores persist after radiotherapy. Participants will record their mouth pain daily using a 0 to 10 scale, with primary measurement focusing on pain reduction over 3 hours after taking the study treatment on the last day of radiotherapy. Additional assessments include pain at other time points, opioid use, quality of life questionnaires, laboratory tests, and safety monitoring. After treatment, there is a 30-day follow-up period to evaluate lasting effects and safety outcomes.

Researchers are evaluating if ifinatamab deruxtecan I-DXd, an antibody-drug conjugate, can treat advanced esophageal squamous cell carcinoma ESCC. This treatment works by attaching to proteins on cancer cells and delivering therapy to destroy them. The study aims to find out how many participants experience tumor shrinkage or disappearance after receiving I-DXd. Participants will receive I-DXd through intravenous infusion every 3 weeks. Treatment continues until the cancer progresses or other criteria for stopping are met. The study is part of a master screening protocol called KEYMAKER-U06 and focuses on participants with unresectable locally advanced or metastatic ESCC who have had prior systemic therapy. During the study, participants will be monitored for tumor response using objective response rate over about 14 months. Researchers will also measure duration of response, progression-free survival, overall survival, and track adverse events for up to 18 to 26 months. Participants undergo regular assessments including imaging and safety evaluations throughout their participation, which may last several months.
