Researchers are evaluating the safety, tolerability, and early effects of 4D-710, an investigational gene therapy, in adults with cystic fibrosis CF lung disease who cannot use or tolerate existing CFTR modulator therapies. A sub-study also includes adults with advanced CF lung disease or frequent lung flare-ups who are currently on CFTR modulator therapy. This Phase 12 open-label trial aims to find appropriate dosing and assess potential benefits for these patient groups. Participants receive a single inhaled dose of 4D-710, which is a gene therapy designed to deliver a corrected version of the CFTR gene to lung cells. The study includes a dose exploration phase for those ineligible for modulator therapy, a dose expansion phase at selected doses, and a sub-study for participants on modulator therapy receiving various doses. Each participant undergoes one administration of the therapy during the trial. Throughout the study, participants are monitored for adverse events over a 60-month period. Evaluations include lung function tests, oxygen saturation measurements, and tracking of pulmonary exacerbations. Participants maintain their existing treatments if applicable, and researchers assess safety and early signs of effectiveness. The total study duration extends up to approximately nine years, including long-term observation after dosing.

Researchers are conducting a multi-center, open-label, single-arm Phase 12 study to evaluate the safety, radiation dosimetry, and early diagnostic performance of 18FFPyQCP in detecting several types of cancers including colorectal cancer, gastric cancer, pancreatic ductal adenocarcinoma, invasive lobular breast cancer, and epithelial ovarian cancer. This study aims to assess how well this imaging agent works in these selected oncology conditions and understand its radiation exposure to patients. Participants receive a single dose of 18FFPyQCP followed by positron emission tomography PETcomputed tomography CT imaging during the PETCT imaging visit. The study includes two cohorts focusing on radiation dosimetry and diagnostic accuracy. Cohort A participants undergo radiation dosimetry assessment up to 360 minutes after injection, while Cohort B participants are evaluated for diagnostic performance in the peritoneum with follow-up procedures lasting up to 42 days. During the study, participants undergo PETCT scans and are monitored for adverse events from screening until 48 hours after injection. Women of childbearing potential must have negative pregnancy tests before imaging and use contraception during the study. Researchers will measure radiation dose, imaging accuracy, and safety outcomes. The total participation time ranges from the screening visit through follow-up assessments, up to approximately 42 days post injection.

Researchers are evaluating the use of PET imaging with the radioligand 18FPI-2620 to detect tau protein deposits in people with Alzheimers disease and healthy controls. This open-label, multi-center, non-randomized Phase 3 study aims to compare PET imaging results during life with brain tissue analysis after death to better understand tau pathology in Alzheimers. The study is sponsored by Lantheus Biosciences Ltd. and focuses on diagnostic accuracy and safety of this imaging technique. Participants receive an intravenous injection of 18FPI-2620 at a dose of 185 MBq 20%. The study involves a PET scan procedure that participants must tolerate, including lying still in the scanner. There are no randomized groups or placebo controls as this is an open-label study. The research compares the PET imaging findings with post-mortem brain autopsy results to evaluate the ability of this imaging to detect tau deposits accurately. During the study, participants undergo PET imaging and are monitored for their ability to tolerate the scan. Brain donation consent is required for post-mortem histopathological comparison. Researchers assess the diagnostic performance of the PET scan in correctly identifying tau-related pathology and Alzheimers disease changes. The primary outcome focuses on the accuracy of visual assessment of PET images compared to autopsy findings, with follow-up continuing until study completion and an average of one year after death.

This research aims to evaluate the use of an investigational imaging agent called 18FPT2385 in patients with renal cell carcinoma RCC, including clear cell RCC and those with Von Hippel-Lindau VHL syndrome. The study is designed to explore how well this imaging method can measure levels of a protein called hypoxia-inducible factor-2alpha HIF2b1 in tumors, which is important for understanding the disease. It is an open-label, non-therapeutic trial involving three patient groups with different disease presentations. Participants will receive an intravenous injection of 18FPT2385 followed by PETCT or PETMRI scans to observe the distribution and uptake of the tracer in tumors. The first group consists of patients scheduled for surgery, who will have imaging before nephrectomy, with results compared to tissue analysis after surgery. The second group includes patients with metastatic clear cell RCC, who will have imaging and a mandatory biopsy of metastatic sites. The third group involves patients with VHL syndrome and various tumors, who will undergo imaging and are encouraged, but not required, to have a biopsy. Some participants may have repeat imaging after initial dosimetry assessments. Throughout the study, patients will undergo multiple imaging sessions, including dynamic and whole-body scans at different time points after tracer injection to analyze tracer kinetics and distribution. Researchers will collect tissue samples for comparison with imaging findings, and participants will continue with standard or experimental treatments as advised by their doctors. The study aims to correlate imaging results with tissue levels of HIF2b1 over up to five years, monitoring safety and feasibility during the process.

Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation CIC. This study is a 26-week, multi-center, randomized, double-blind, placebo-controlled trial followed by a 4-week treatment-free safety follow-up period. It aims to compare three different doses of tenapanor with a placebo taken twice daily to assess their impact on constipation symptoms. The study includes a 2-week screening period to confirm eligibility, followed by a 26-week randomized treatment period where patients receive either 5 mg, 25 mg, or 50 mg of tenapanor twice daily, or a matching placebo. Patients record their constipation symptoms daily in an electronic diary. After the treatment period, there is a 4-week safety follow-up without treatment to monitor any adverse effects. Participants will have regular visits every 2 to 6 weeks for safety checks including medical assessments, vital signs, ECG, and lab tests. Their symptom diaries will be reviewed throughout the study. The main outcome measured is the durable complete spontaneous bowel movements response at 12 weeks. Secondary outcomes include changes in bowel movement frequency, stool consistency, and straining. The total study duration is approximately 32 weeks including all phases.

Researchers are studying treatments for locally advanced or metastatic colorectal cancer mCRC that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This trial aims to evaluate if adding the targeted therapies calderasib and cetuximab to the standard chemotherapy regimen mFOLFOX6 can provide better outcomes compared to mFOLFOX6 with or without bevacizumab. The study focuses on the safety and tolerability of these combinations and whether they can help people live longer without their cancer growing or spreading. Participants will be assigned to one of two groups. One group will receive calderasib orally, cetuximab every two weeks, and mFOLFOX6 chemotherapy including oxaliplatin, leucovorin or levofolinate calcium, and 5-fluorouracil every two weeks. The other group will receive mFOLFOX6 chemotherapy with or without bevacizumab every two weeks, based on the investigators decision. Treatments will continue until certain stopping criteria are met. During the study, participants will be monitored for side effects and treatment tolerance, with regular assessments of cancer progression. Researchers will measure outcomes such as dose-limiting toxicities, adverse events, progression-free survival, and overall survival. Quality of life will also be evaluated through questionnaires. The study may last up to several years, with monitoring continuing for safety and effectiveness throughout the treatment period and follow-up.

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 studying the safety and initial effects of T3011, given directly into tumors, alone and combined with the intravenous drug pembrolizumab. This Phase 12a open-label study focuses on adults with advanced or metastatic solid tumors, including melanoma, head and neck squamous cell carcinoma HNSCC, sarcoma, cutaneous squamous cell carcinoma cSCC, and non-small cell lung cancer NSCLC. The study aims to find safe dose levels and assess how well these treatments are tolerated and work in these cancer types. The study involves several groups Phase 1 tests increasing doses of T3011 alone to determine a recommended dose. Phase 2a Part 1 evaluates T3011 alone in participants with melanoma, HNSCC, sarcoma, and cSCC. Phase 2a Part 2 studies T3011 with pembrolizumab in NSCLC patients. A rollover arm allows participants whose cancer progresses on T3011 alone to receive the combination treatment. T3011 is given as an intratumoral injection every two weeks, and pembrolizumab is given intravenously every three weeks when combined. Participants will have tumor biopsies, imaging, and laboratory tests to monitor safety, drug levels, and cancer response. Researchers will track side effects and measure outcomes like tumor response and survival for up to two years after the first dose. Safety and tolerability are closely followed throughout, with additional monitoring for immune responses and drug presence in bodily fluids. Participants may be followed for up to one year after their last treatment dose to assess overall survival and long-term effects.

Researchers are evaluating new treatment options for people living with HIV-1 Human Immunodeficiency Virus Type 1 who have not been treated before. The current standard treatment, antiretroviral therapy ART, involves taking multiple medicines daily and may cause other health problems. This study aims to compare a new study ART combining two medicines, islatravir and ulonivirine, taken once a week, against the standard daily ART to see if it works as well and is safe and tolerable. Participants will receive one of several treatments for 96 weeks the study ART with islatravir and ulonivirine taken once weekly, the standard ART with bictegraviremtricitabinetenofovir alafenamide BICFTCTAF taken once daily, or combinations involving placebos matching these treatments. The study includes two phases Phase 2 which is open-label, and Phase 3 which is double-blind and randomized. During the study, participants will have regular assessments including measuring the amount of HIV-1 RNA in their blood and monitoring for adverse events and medication tolerance. Researchers will evaluate how well the treatments control the virus and affect immune cells over 24, 48, and 96 weeks. Safety monitoring will continue for about 102 weeks. The total study duration for participants is up to 96 weeks of treatment plus follow-up.

Researchers are investigating new treatment options for breast cancer that is hormone receptor-positive HR and human epidermal growth factor receptor 2-negative HER2-, specifically for cases that are unresectable locally advanced or metastatic. This type of breast cancer involves cancer cells that depend on hormones like estrogen or progesterone and have low HER2 protein levels. The study focuses on comparing the effects of patritumab deruxtecan against chemotherapy or trastuzumab deruxtecan in patients whose cancer has progressed despite prior treatments. Participants receive either patritumab deruxtecan through intravenous infusions every three weeks for about 13 months or a treatment chosen by their physician, which may include various chemotherapy drugs or trastuzumab deruxtecan, administered according to specific schedules for up to 13 months. The study is randomized and open-label, meaning participants are randomly assigned to one of the treatment groups, and both the patients and researchers know which treatment is given. Throughout the study, participants undergo regular assessments to monitor cancer progression and overall survival for up to approximately 85 months. Researchers evaluate tumor response, duration of response, and changes in quality of life using standardized questionnaires. Safety is carefully monitored by recording adverse events and treatment discontinuations. The goal is to understand if patritumab deruxtecan can improve outcomes compared to current treatment options.
