Researchers are investigating new treatments for advanced renal cell carcinoma RCC that has returned after prior therapy. The study aims to find out if the combination of belzutifan and zanzalintinib can help people with recurrent advanced RCC live longer without their cancer worsening compared to the drug cabozantinib. This is a phase 3 randomized trial evaluating these treatments in participants who have experienced recurrence during or after prior anti-PD-1L1 therapy. Participants are randomly assigned to receive either belzutifan plus zanzalintinib taken orally once daily or cabozantinib taken orally once daily. They continue their assigned treatment until certain reasons require stopping the study intervention. The study compares the effects of these treatments on cancer progression and survival among people with advanced RCC who have had disease recurrence after adjuvant therapy. During the study, participants will be regularly monitored for progression-free survival and overall survival for up to about 73 months. Researchers will also assess tumor response, duration of response, adverse events, and quality of life using questionnaires over approximately 25 months. The study involves ongoing evaluations to understand how these treatments affect symptoms, functioning, and overall health during long-term follow-up.

Researchers are evaluating if combining the medicines calderasib and subcutaneous pembrolizumab can more effectively treat people with non-small cell lung cancer NSCLC that has a KRAS G12C mutation. The study aims to find out whether patients receiving calderasib with pembrolizumab live longer without their cancer growing or spreading compared to those receiving pembrolizumab with chemotherapy. This is a Phase 3 clinical trial focusing on first-line treatment for advanced or metastatic nonsquamous NSCLC. Participants are assigned to one of two groups. One group receives subcutaneous pembrolizumab plus berahyaluronidase alfa every 6 weeks for up to 18 cycles about 2 years along with oral calderasib until treatment discontinuation criteria are met. The other group receives the same pembrolizumab and berahyaluronidase alfa regimen plus chemotherapy with pemetrexed and either carboplatin or cisplatin infusions during the early cycles. Treatment continues based on individual response and tolerability. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess progression-free survival, overall survival, response rates, and quality of life using questionnaires and symptom scores over several years. Safety will be monitored through adverse event reporting. The trial lasts up to about 7 years with ongoing evaluation of health outcomes and side effects to understand the impact of these treatment combinations.

Researchers are investigating new treatments for high-risk, early-stage breast cancer, specifically targeting two types triple-negative breast cancer TNBC and hormone receptor-low positiveHER2-negative breast cancer. These cancers are characterized by low or no HER2 protein and low hormone receptor presence. The study aims to evaluate if adding sacituzumab tirumotecan sac-TMT to pembrolizumab and chemotherapy can better reduce cancer cells in tumors and lymph nodes and improve the length of time patients live without cancer progression compared to pembrolizumab with chemotherapy alone. Participants in this trial receive one of two treatment plans. One group gets sacituzumab tirumotecan intravenously every two weeks plus pembrolizumab every three weeks for 12 weeks, followed by pembrolizumab with carboplatin and paclitaxel for another 12 weeks. After 3 to 6 weeks, surgery and optional radiation therapy take place, followed by pembrolizumab for about 28 weeks. Participants with remaining disease may receive additional treatments chosen by their doctors, including olaparib, capecitabine, doxorubicin, epirubicin, or cyclophosphamide. The other group receives chemotherapy drugs carboplatin and paclitaxel with pembrolizumab initially, then pembrolizumab with cyclophosphamide and doxorubicin or epirubicin, followed by surgery, optional radiation, and pembrolizumab for about 28 weeks, with similar additional options for residual disease. During the study, participants undergo core needle biopsies, receive intravenous infusions of study drugs, and have surgery and possible radiation therapy. Researchers assess outcomes such as the percentage of participants with no detectable cancer cells at surgery pathological complete response, event-free survival up to about 92 months, and overall survival up to nearly 10 years. Quality of life and side effects are monitored through questionnaires and adverse event tracking. The study lasts several years, with various assessments throughout treatment and follow-up periods to gather comprehensive data on treatment effects and safety.

Researchers are evaluating the use of Gamunex-C, an intravenous immunoglobulin treatment, in people with certain immune problems caused by Chronic Lymphocytic Leukemia, Multiple Myeloma, or Non-Hodgkin Lymphoma. The study aims to show that these participants experience fewer serious infections when they receive Gamunex-C along with their usual medical care. This is an open-label, single-arm clinical trial sponsored by Grifols Biologicals, LLC, focusing on safety, effectiveness, and how the drug moves through the body. Participants receive Gamunex-C at a dose of 500 mgkg through an IV every 4 weeks, totaling 13 doses over one year. The treatment phase starts on Day 1 Week 1 and continues through Week 48. There are no placebo or comparison groups since all participants get the study treatment in addition to their standard care. During the study, participants will be monitored for serious bacterial infections and other types of infections while receiving treatment and for 28 days after the last dose, or until they start any other immunoglobulin replacement therapy. Researchers will track infection rates, time to infection onset, hospitalizations due to infections, and antibiotic use. The total duration of participation is about one year, including treatment and follow-up for safety and effectiveness.

Researchers are evaluating the effectiveness of combining tarlatamab with durvalumab, carboplatin, and etoposide compared to the combination of durvalumab, carboplatin, and etoposide alone in treating patients with untreated extensive stage small-cell lung cancer ES-SCLC. The main goal is to see if the addition of tarlatamab can help patients live longer overall. This is a phase 3, open-label, randomized study conducted across multiple centers. Participants are assigned to one of two groups. One group receives tarlatamab combined with durvalumab, carboplatin, and etoposide for four treatment cycles, followed by maintenance treatment with tarlatamab and durvalumab. The other group receives durvalumab, carboplatin, and etoposide for four cycles, followed by durvalumab alone. All drugs are given as intravenous infusions. The study lasts up to approximately 3.5 to 4 years to assess survival and disease progression. During the study, participants will undergo regular assessments including evaluations of overall survival and progression-free survival. Other measures include response to treatment, disease control, duration of response, and monitoring for treatment-related adverse events. Blood tests will evaluate drug levels and antibody development. The research team will carefully monitor participants throughout the treatment and follow-up periods, keeping track of their health and any side effects.

Researchers are evaluating the addition of Tersolisib LY4064809STX-478 to other anti-cancer drugs as a first treatment for adults with advanced hormone receptor-positive HRhuman epidermal growth factor receptor 2-negative HER2- breast cancer that has a PIK3CA mutation. This Phase 3 randomized, double-blind, placebo-controlled trial aims to understand the efficacy and safety of this combination compared to placebo, focusing on improving outcomes for patients with this specific genetic change. Participants receive LY4064809 orally in one of two doses combined with a CDK46 inhibitor such as Ribociclib, Palbociclib, or Abemaciclib and endocrine therapy ET administered orally or via intramuscular injection. The comparison group receives a placebo combined with the same CDK46 inhibitor and ET. The study includes two parts Part 1 explores dose optimization, and Part 2 evaluates the treatment combinations effectiveness and safety as a first-line therapy. During the study, participants will have regular assessments to monitor cancer response, progression, and safety over an estimated period of up to 5 years or more. Researchers will measure outcomes such as overall response rate, progression-free survival, duration of response, overall survival, and quality of life. Treatment continues as long as the cancer benefits without intolerable side effects. Safety monitoring, laboratory tests, and quality of life questionnaires are part of the participant involvement throughout the trial.

Researchers are evaluating whether adding sacituzumab tirumotecan to pembrolizumab after surgery improves treatment outcomes for adults with resectable non-small cell lung cancer NSCLC who do not achieve a complete response after initial therapy. This Phase 3 trial compares the combination of sacituzumab tirumotecan plus pembrolizumab against pembrolizumab alone, focusing on disease-free survival assessed by a blinded independent central review. The study is sponsored by Merck Sharp & Dohme LLC and targets participants with specific stages of NSCLC who have undergone neoadjuvant therapy and surgery but still have residual disease. Participants first receive neoadjuvant therapy consisting of pembrolizumab combined with double-platinum chemotherapy tailored to the tumor type for up to 12 weeks before surgery. After surgery, those not achieving pathological complete response are assigned to either receive sacituzumab tirumotecan infusions every two weeks for up to 24 weeks alongside pembrolizumab monotherapy every six weeks for approximately 42 weeks, or pembrolizumab monotherapy alone on the same schedule. Rescue medications to manage infusion reactions may be given as needed during the study. Throughout the trial, participants undergo assessments including radiological scans, tumor tissue analysis for markers like PD-L1 and TROP2, and monitoring for adverse events and quality of life changes. Key outcomes include disease-free survival, overall survival, distant metastasis-free survival, and lung cancer-specific survival, with evaluations continuing for up to nearly 10 years. Safety and tolerability are closely monitored, and questionnaires assess physical functioning, symptoms like cough and chest pain, and overall health status during and after treatment.

Researchers are evaluating the levels of drug exposure in adults with locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma. This Phase 3 study compares tislelizumab given by subcutaneous injection versus intravenous infusion as first-line therapy combined with chemotherapy. The study involves approximately 351 participants and aims to understand the treatments effects in this patient group. Participants will be randomly assigned to receive either tislelizumab 300 mg by subcutaneous injection or 200 mg by intravenous infusion on Day 1 of each 21-day cycle. Both groups will also receive chemotherapy tailored to each patient. The study includes a screening period, a treatment period with repeated cycles, and a follow-up period to assess long-term outcomes. During the study, participants will be monitored through various assessments, including tumor evaluations and biomarker tests. Researchers will measure drug concentration levels, response rates, progression-free survival, overall survival, and adverse events for up to two years. Safety and treatment effectiveness will be closely followed throughout the study duration, which ends in April 2028.

Researchers are evaluating AMG 436, a drug being studied for safety and optimal dosing, in participants with metastatic or locally advanced solid tumors that have microsatellite instability-high MSI-H or mismatch repair deficiency dMMR. This Phase 11b trial aims to determine the maximum tolerated dose and recommended dose of AMG 436 both as a single therapy and combined with other anti-cancer treatments. The study focuses on safety, tolerability, and how the drug behaves in the body. Participants may receive AMG 436 alone or in combination with other therapies. The study includes several parts dose escalation for monotherapy, evaluation under fed and fasted conditions in the US, combination dose escalation, dose expansion and optimization of monotherapy, and combination dose expansions with chemotherapy. Each part explores different dosing strategies and combinations to find the best approach. During the study, participants will be monitored closely for side effects and dose-limiting toxicities up to 21 days after dosing, with continued safety follow-up for up to five years. Blood samples will be collected to measure drug levels and activity. Tumor response will be assessed using standard imaging criteria over several years to evaluate treatment effectiveness. Participants will have regular visits for assessments, and overall survival and disease progression will be tracked for up to five years.

Researchers are studying premenopausal women with early-stage breast cancer that is estrogen receptor-positive and HER2-negative, focusing on tumors with specific gene recurrence scores. The trial aims to find out if adding chemotherapy to ovarian function suppression plus endocrine therapy improves invasive breast cancer-free survival compared to ovarian function suppression plus endocrine therapy alone. This Phase III trial addresses the need for better treatments in younger women, given their higher risk and past conflicting study results on ovarian suppression and chemotherapy. Participants are randomly assigned to one of two groups one receiving ovarian function suppression combined with an aromatase inhibitor for five years, and the other receiving adjuvant chemotherapy followed by the same ovarian function suppression and aromatase inhibitor regimen. Choices for the aromatase inhibitor and gonadotropin releasing hormone agonist are made by the investigator, with options including drugs such as goserelin, leuprolide, or triptorelin. Endocrine treatment beyond five years is at the investigators discretion, and bilateral oophorectomy may be used instead of ovarian suppression if preferred. During the study, participants are monitored over 11 years from randomization, with measurements including invasive breast cancer-free survival as the primary outcome. Secondary outcomes include disease-free survival, overall survival, recurrence intervals, menopausal symptoms, and pain during aromatase inhibitor therapy. Safety and treatment effects are assessed through regular evaluations, and participants continue to be followed long term to understand the impact of treatments on their breast cancer outcomes.
