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 NX-5948, a treatment for adults with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have previously been treated with both a Bruton's Tyrosine Kinase inhibitor (BTKi) and a B-cell Lymphoma-2 inhibitor (BCL-2i). NX-5948 works by destroying the BTK protein, which differs from BTK inhibitors that only block part of its action. This phase 2, open-label study aims to assess how well NX-5948 works, its safety, and how long patients can take it. All participants will receive NX-5948 orally once daily in continuous 28-day cycles until their cancer worsens or other reasons require stopping treatment. During treatment, patients will have regular cancer and health check-ups. If treatment stops without cancer progression, monitoring will continue until disease worsening occurs. Participation in the study could last up to five years or longer if the disease remains stable. Throughout the study, researchers will regularly evaluate patients' cancer status and overall health. They will monitor the response to NX-5948, including the objective response rate without partial response with lymphocytosis, as assessed by an independent committee for up to approximately five years. Safety and drug levels in the bloodstream will also be tracked, ensuring comprehensive long-term monitoring of patients in the trial.

Researchers are evaluating the study medicine PF-08046054 compared to the standard chemotherapy drug docetaxel in adults with non-small cell lung cancer (NSCLC) that has spread or cannot be removed with surgery or radiation. Participants must have PD-L1 expression on 1% or more of their tumor cells and have experienced cancer progression during or after treatment with PD-L1 or PD-1 inhibitors, platinum-based chemotherapy, and targeted therapies for those with known genetic mutations. The trial is a Phase 3 randomized study to better understand how well PF-08046054 works alone compared to docetaxel alone. Participants will be randomly assigned to receive either PF-08046054 or docetaxel. Those in the PF-08046054 group will get intravenous (IV) infusions twice every 21-day cycle, while those in the docetaxel group will receive one IV infusion every 21 days. The treatment period may last up to 5 years if their NSCLC responds to the therapy. No other treatments are combined during the study period. Throughout the study, participants will have regular clinic visits for evaluations and monitoring to see how they respond to the treatment. Researchers will collect information on overall survival over approximately 5 years. They will also monitor safety and disease progression during these visits to understand the long-term effects and benefits of the treatments.

Researchers are evaluating a new medicine called PF-08634404 combined with chemotherapy for people aged 18 and older who have locally advanced or metastatic gastric, gastroesophageal junction, or esophageal adenocarcinoma. The study includes participants who have not received prior treatment for advanced or metastatic disease and are in good health based on medical tests. This research is designed as a Phase 2/3 trial to learn about safety, response, and compare this new treatment to an approved therapy called nivolumab plus chemotherapy. The study has two parts: the first part assesses the safety and response to PF-08634404 with chemotherapy, and the second part compares this combination to nivolumab with chemotherapy. Treatments are given intravenously in repeated cycles. Participants receive either PF-08634404 plus chemotherapy or nivolumab plus chemotherapy based on the study phase and group assignment. During the study, participants undergo regular evaluations including medical tests to monitor organ function and safety. Researchers will measure treatment response using RECIST 1.1 criteria, track adverse events, and assess progression-free survival and overall survival over approximately four years. Follow-up continues through 90 days after the last treatment to monitor side effects and overall health.

Researchers are evaluating surgical and minimally invasive treatments for lumbar spinal stenosis (LSS) by comparing Medicare patients who received the MILD procedure against those who had interspinous process decompression (IPD). The study focuses on outcomes such as the rate of harms related to the initial procedure and the frequency of additional surgical or minimally invasive interventions within 24 months after treatment. Enrollment includes patients treated from January 1, 2017, onward, with continuation until the sponsor decides to stop. The MILD procedure involves percutaneous image-guided lumbar decompression, performed under fluoroscopy through a dorsal approach to partially remove tissue and bone at the affected spinal level. The control group receives the IPD procedure for LSS. Both groups are monitored for a 24-month period post-index procedure using Medicare claims data to track reoperations and any harms. Participants contribute data through Medicare claims without needing prior enrollment or consent, as the study is exempt from IRB oversight. Researchers collect and analyze information on procedure-related harms and subsequent interventions over two years. This approach allows evaluation of long-term safety and effectiveness outcomes for patients treated with either MILD or IPD.

This research evaluates anonymous, previously collected medical data to review the outcomes of different treatment methods for chronic pain. The study is a retrospective review involving multiple centers and independent patient groups to compare results across various subgroups. The study examines clinical outcomes related to the use of spinal cord stimulation, radiofrequency (RF), and other implantable device systems from Boston Scientific and other manufacturers. Multiple cohorts will be analyzed based on the type of treatment system used. Participants' medical charts will be reviewed to measure response rates through approximately two years of follow-up. The study focuses on clinical results documented in patient records without any new treatment or intervention administered during the study.

Researchers are studying the effects of Adagrasib alone and combined with pembrolizumab in adults with advanced or metastatic non-small cell lung cancer (NSCLC) who have the KRAS G12C mutation. The Phase 2 part evaluates these treatments in patients who are candidates for first-line therapy, with different groups based on their PD-L1 tumor proportion scores (TPS). The Phase 3 part compares the combination of Adagrasib and pembrolizumab against pembrolizumab alone in patients with NSCLC having PD-L1 TPS of 50% or higher. In Phase 2, there are three patient groups: two with PD-L1 TPS less than 1% randomized to receive either Adagrasib monotherapy or Adagrasib plus pembrolizumab, and one group with PD-L1 TPS of 1% or higher treated with the combination. Adagrasib is given orally at doses of 400 mg twice daily or 600 mg twice daily depending on the group, while pembrolizumab is administered intravenously at 200 mg every three weeks. Phase 3 patients are randomized to receive either Adagrasib 400 mg twice daily plus pembrolizumab 200 mg every three weeks or pembrolizumab alone. Participants will undergo various assessments including brain imaging, tumor measurements, and evaluations of safety and treatment effects over 22 months in Phase 2 and 36 months in Phase 3. Researchers will monitor efficacy, safety, and drug levels, as well as patient-reported outcomes and genetic biomarkers. The study includes patients with untreated or previously treated brain metastases under specific conditions and excludes those with prior systemic treatments for advanced NSCLC or certain brain lesion characteristics.

Researchers are evaluating the combination of quaratusugene ozeplasmid and atezolizumab as a maintenance treatment for patients with Extensive Stage Small Cell Lung Cancer (ES-SCLC) who have not experienced tumor progression after initial induction therapy with carboplatin, etoposide, and atezolizumab. This open-label, multi-center Phase 1/2 study aims to determine the recommended dose and assess the safety and effectiveness of this combination therapy in this patient group. During Phase 1, the recommended Phase 2 dose (RP2D) of quaratusugene ozeplasmid combined with atezolizumab was established. In Phase 2, patients receive quaratusugene ozeplasmid at the RP2D alongside atezolizumab as maintenance therapy. Quaratusugene ozeplasmid is an experimental gene-based therapy designed to target cancer cells and modulate the immune response, while atezolizumab is an antibody that helps activate the immune system against cancer. The study closely monitors toxicity using standard criteria and reviews serious adverse events and dose-limiting toxicities. Participants undergo assessments to monitor safety and effectiveness, including evaluation of progression-free survival over 18 weeks from the start of maintenance therapy and determination of the maximum tolerated dose during the initial 21 days of dosing at each level. Researchers conduct laboratory tests, imaging, and clinical evaluations throughout the treatment period. The study includes careful safety monitoring and requires participants to meet specific health criteria before enrollment. Overall participation spans both study phases with ongoing treatment and follow-up.

Researchers are evaluating the effectiveness of radiation therapy with or without the chemotherapy drug cisplatin in patients with stage III-IVA squamous cell carcinoma of the head and neck who have had surgery to remove their tumors. This phase II trial aims to understand if adding cisplatin to radiation therapy improves disease-free survival, especially considering the role of p53 mutations in the cancer cells. The study also investigates toxicities and potential genomic factors that might influence treatment outcomes. Patients are randomly assigned to one of two treatment groups. One group receives intensity-modulated radiation therapy (IMRT) alone once daily, five days a week for six weeks. The other group receives the same radiation treatment combined with weekly intravenous cisplatin over one to two hours, also for six weeks. Treatment continues as long as there is no disease progression or unacceptable side effects. During the study, participants undergo regular follow-ups every six months for three years and then yearly for seven more years to monitor for cancer recurrence or new tumors. Researchers assess disease-free survival, tracking the time from randomization until cancer returns, a second tumor develops, or death. Additional laboratory tests and biomarker analyses are performed to understand genetic changes and treatment effects. Safety and toxicities are closely monitored throughout the study period.

Researchers are evaluating a new medicine called PF-08634404 to see how well it works in adults with colorectal cancer that has spread or returned after previous treatments. This study focuses on whether PF-08634404 combined with approved chemotherapy can help patients compared to another approved medicine called Bevacizumab combined with chemotherapy. The study is a Phase 3, double-blind, randomized trial involving participants who have metastatic colorectal cancer and have not received prior systemic therapy for metastatic disease. Participants will be randomly assigned to one of two groups: one receiving PF-08634404 plus chemotherapy, and the other receiving Bevacizumab plus chemotherapy. Both treatments are given by intravenous infusion in cycles. Participants may continue treatment if it is beneficial and side effects are manageable. Treatments are administered at clinical sites with medical staff monitoring participants during and after each infusion. During the approximately 33-month study, participants will visit the study site regularly for treatment, health checks, and tests. After stopping treatment, there will be a follow-up visit about 30 to 37 days later to assess health and side effects. Participants will also have follow-up every 12 weeks by phone, in person, or through health record reviews to monitor their health status and any new treatments. The main outcomes measured include progression-free survival and overall survival over about 4 years.
