Researchers are evaluating treatments for breast cancer that is hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-), specifically in cases where the cancer is either locally advanced and cannot be removed by surgery or has spread to other parts of the body (metastatic). The study aims to determine if patritumab deruxtecan (also called HER3-DXd or MK-1022) helps patients live longer overall or without the cancer growing compared to chemotherapy or trastuzumab deruxtecan. This is a Phase 3 clinical trial focusing on this particular type of breast cancer. Participants receive one of several treatments: patritumab deruxtecan through intravenous infusion, chemotherapy options like paclitaxel or nab-paclitaxel via IV, oral capecitabine tablets, liposomal doxorubicin via IV, or trastuzumab deruxtecan via IV infusion. The study compares the effects of patritumab deruxtecan alone to the treatment chosen by the physician. Treatments are administered according to standard dosing schedules during the trial. During the study, participants are monitored for how long they live without the cancer progressing (up to about 45 months) and overall survival (up to about 85 months). Researchers assess disease status through imaging and other evaluations. Participants have regular check-ups to monitor health, treatment effects, and any side effects. The study tracks treatment response and safety over the extended follow-up period to understand the benefits and risks of the therapies.

This research aims to investigate the frequency of Neuronal Ceroid Lipofuscinosis Type 2 (CLN2) in children aged 2 to 6 who exhibit nonspecific neurological symptoms such as idiopathic seizures, speech disorders, and motor dysfunctions. The study targets children without hypoxic ischemic encephalopathy, head trauma, or developmental brain anomalies who visit Pediatric Metabolism, Neurology, and Developmental Pediatrics clinics over a 12-month enrollment period. It is a multicenter, non-drug screening study designed to better understand CLN2 disease among this population. During the study, demographic data, medical and family history will be collected at the first visit. Assessments will include seizure frequency, cognitive and language development evaluations, physical exams focusing on muscle strength, gait, and coordination, as well as neurological tests such as EEG and MRI scans. Children showing specific neurological signs or imaging findings will have blood samples taken for Tripeptidyl Peptidase 1 enzyme measurement. Those with low enzyme activity will undergo genetic testing to investigate CLN2 disease. Participants will be monitored for disease frequency over one year. Researchers will measure clinical and demographic characteristics including speech impairment, motor symptoms, EEG responses, and brain imaging changes. Safety monitoring includes obtaining informed consent and following up on enzyme and genetic test results. Total participation spans from initial screening through diagnostic testing and data collection during the 12-month study period.

Researchers are evaluating the safety and effectiveness of HLX22 combined with trastuzumab and chemotherapy as the first treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 2, double-blind, randomized, and multiregional study compares this combination against trastuzumab and chemotherapy with or without pembrolizumab. The study aims to measure how well the treatments work in controlling the disease and improving survival for up to five years. Participants will be randomly assigned to one of two groups. One group receives HLX22 at 15 mg/kg every three weeks along with trastuzumab, chemotherapy (XELOX regimen), and possibly a placebo for pembrolizumab. The other group receives a placebo for HLX22 plus trastuzumab, chemotherapy (XELOX), and possibly pembrolizumab every three weeks. Treatment continues until the disease worsens, unacceptable side effects occur, withdrawal of consent, or other protocol-specified reasons. Throughout the study, participants will undergo regular assessments including tumor scans reviewed by an independent committee to evaluate progression-free survival and overall survival over up to five years. Other evaluations include safety monitoring and organ function tests. The study tracks how long patients live without disease progression and overall survival, aiming to better understand the benefits and risks of HLX22 combined with current standard treatments.

This trial investigates the safety and effectiveness of rilvegostomig combined with fluoropyrimidine and trastuzumab deruxtecan (T-DXd) compared to trastuzumab, chemotherapy, and pembrolizumab in adults with HER2-positive locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors express PD-L1 with a combined positive score of 1 or higher. Additionally, rilvegostomig combined with trastuzumab and chemotherapy is studied separately to understand each component's contribution. This Phase 2, randomized, open-label, global study is conducted at 200-250 sites in about 25 countries. Participants are randomly assigned to one of three arms: Arm A receives rilvegostomig, fluoropyrimidine, and T-DXd; Arm B receives trastuzumab, chemotherapy, and pembrolizumab; Arm C receives rilvegostomig, trastuzumab, and chemotherapy. Treatments are administered mostly by intravenous infusion every three weeks, with capecitabine given orally twice daily. The study compares these treatment regimens to evaluate their effects on the cancer. Throughout the study, participants undergo assessments including tumor measurements, organ function tests, and heart function evaluation to ensure safety and monitor disease progression. The main outcomes measured are progression-free survival and overall survival for up to approximately six years. Researchers will also monitor adverse events and overall health status during and after treatment.

Researchers are evaluating how well elacestrant works compared to standard endocrine therapy in adults with node-positive, Estrogen Receptor-positive (ER+), Human Epidermal Growth Factor-2 negative (HER2-) early breast cancer who are at high risk of the cancer returning. This is a Phase 3 global, multicenter, randomized, open-label study focusing on participants who have had early invasive breast cancer removed and meet specific receptor and risk criteria. The study aims to understand which treatment better prevents invasive breast cancer over up to five years. Participants will receive either elacestrant or one of several standard endocrine therapies, including anastrozole, letrozole, exemestane, or tamoxifen, all given as oral tablets. Treatments will be administered according to the study plan, with careful monitoring throughout the trial. The study includes adults who have already received between 24 and 60 months of prior endocrine therapy, with or without certain inhibitors, and who have completed or stopped these treatments as required. During the study, participants will be monitored for invasive breast cancer-free survival for up to five years. Researchers will perform regular assessments to track treatment effects, side effects, and cancer recurrence. The study also includes safety monitoring and may involve additional tests or evaluations as needed to ensure participant well-being throughout the trial.

Researchers are evaluating the effectiveness of adding LY3537982 (olomorasib) to standard anti-cancer drugs compared to standard treatment alone in participants with untreated advanced non-small cell lung cancer (NSCLC) that has a specific KRAS G12C gene mutation. This pivotal Phase 3 trial includes participants with locally advanced or metastatic NSCLC and considers their programmed death-ligand 1 (PD-L1) expression levels. The study includes multiple parts: Dose Optimization, Part A, and Part B are randomized, while Safety Lead-In for Part B and Part C are non-randomized. Treatments being assessed include LY3537982 taken orally, pembrolizumab administered intravenously, and standard chemotherapy drugs such as cisplatin, carboplatin, and pemetrexed given intravenously. Participants receive these treatments according to their assigned groups based on their PD-L1 expression and tumor histology. Participants will be monitored with regular assessments including measuring disease progression, safety evaluations, and treatment emergent adverse events for up to approximately one year, with overall study participation potentially lasting up to three years depending on individual response and health status. Outcome measures focus on progression-free survival and safety, capturing any adverse events from the start of treatment until disease progression or death.

Researchers are evaluating Risvutatug rezetecan (Ris-Rez), a new medicine that targets specific proteins called B7-H3 on cancer cells to reduce the cancer's ability to grow and spread. This study focuses on participants with relapsed extensive-stage small cell lung cancer (ES-SCLC) who have previously received platinum-based systemic therapy combined with a PD-(L)1 inhibitor. The trial aims to compare how well Ris-Rez works versus the standard treatment topotecan in shrinking tumors or making them disappear, and whether Ris-Rez helps participants live longer. The study also assesses the safety and tolerability of Ris-Rez compared to topotecan and gathers information on side effects of both treatments. Participants will be randomly assigned to receive either Ris-Rez, administered as a biological treatment, or topotecan, given as a drug treatment. The study is a phase 3, multicenter, randomized, open-label clinical trial. Both treatments will be provided according to the study protocol, and participants will be monitored carefully throughout the treatment period. During the study, participants will undergo assessments to monitor tumor response using RECIST 1.1 criteria and overall survival for up to approximately 113 weeks. Researchers will also evaluate participants' organ function, performance status, and side effects. Safety monitoring includes checking for cardiovascular health, infections, bleeding, and lung conditions. The study requires participants to provide informed consent and comply with study procedures and restrictions throughout their involvement.

Researchers are evaluating the safety and effectiveness of Ifinatamab Deruxtecan (I-DXd) compared to treatment chosen by physicians for adults with relapsed extensive-stage small cell lung cancer (ES-SCLC). The study aims to find out if I-DXd can improve the objective response rate, meaning the proportion of patients whose cancer shrinks or disappears, and extend overall survival time compared to other treatments. Secondary goals include assessing safety, patient-reported outcomes, immune response to I-DXd, B7-H3 protein levels, and how the drug is processed in the body. Participants will receive either I-DXd at a dose of 12 mg/kg given intravenously on the first day of each 21-day treatment cycle or one of the physician's choice treatments including Topotecan, Amrubicin, or Lurbinectedin, administered according to local standards of care. The study is randomized and open-label, meaning treatments are assigned by chance and both patients and doctors know which treatment is given. During the study, participants will be closely monitored with tumor assessments to evaluate response and detect disease progression, safety evaluations, and quality of life questionnaires. The main outcomes measured are the objective response rate assessed by a blinded independent review and overall survival time, tracked for up to approximately five years after randomization. Researchers will also monitor for any adverse effects and collect health economics data to understand the broader impact of treatments.

Researchers are evaluating the effectiveness of Saruparib (AZD5305) compared to placebo when added to a standard radiation therapy (RT) and androgen deprivation therapy (ADT) regimen in men with high-risk and very high-risk localized or locally advanced prostate cancer who have a BRCA gene mutation. This phase III study aims to assess whether Saruparib can improve metastasis-free survival in this population. About 700 adult male participants will be randomly assigned to receive either Saruparib or placebo along with ADT. There are two groups: Cohort A includes 400 participants with newly diagnosed high-risk or very high-risk prostate cancer treated with primary RT or with high-risk biochemical recurrence after radical prostatectomy receiving salvage RT. Cohort B includes 300 participants with very high-risk locally advanced prostate cancer receiving primary RT combined with ADT and abiraterone. Saruparib and placebo will be given orally, and standard ADT and abiraterone with prednisone/prednisolone will be administered as per the regimen. Participants will be followed for up to about 93 months to monitor metastasis-free survival and overall safety. Assessments include imaging scans like CT, MRI, bone scans, and PSMA-PET to confirm disease status. The study also monitors organ function, performance status, and treatment adherence. An independent committee will review safety and efficacy data throughout the trial to ensure participant well-being and study integrity.

Researchers are evaluating the safety and effectiveness of a new oral medicine called vepugratinib compared with a placebo in adults with advanced or metastatic urothelial carcinoma, a type of bladder cancer that has a specific FGFR3 genetic alteration. This Phase 3 study aims to see if vepugratinib combined with two other drugs, enfortumab vedotin (EV) and pembrolizumab, can improve treatment outcomes for people who have not received prior systemic therapy for their cancer. Participants will receive either vepugratinib or placebo taken orally alongside enfortumab vedotin and pembrolizumab, both administered by intravenous infusion. The study is randomized, double-blind, and placebo-controlled to ensure reliable comparison between the vepugratinib and placebo groups. Treatment and monitoring will continue for up to approximately 6 years, allowing long-term assessment of safety and treatment effects. During the study, participants will be regularly evaluated for treatment-related side effects, response rates, and how long the cancer remains controlled without progression. Researchers will use established criteria to measure tumor response and will conduct thorough safety monitoring over the entire study period. Participation may last up to six years, during which participants will undergo laboratory tests, imaging, and clinical assessments to track their health and treatment response.
