Researchers are evaluating the effectiveness, safety, tolerability, and pharmacodynamics of multiple doses of APL-3007 combined with Syfovre/Pegcetacoplan (APL-2) in patients aged 60 years and older diagnosed with geographic atrophy secondary to age-related macular degeneration. This Phase 2, randomized, placebo-controlled, multicenter, masked study focuses on measuring changes in retinal pigment epithelium lesions using advanced artificial intelligence-based SD-OCT imaging. Participants will receive either the combination of APL-3007 with pegcetacoplan (APL-2) or a placebo. The study includes a treatment period with multiple doses administered, aiming to assess the impact on geographic atrophy lesions over a 12-month period. Syfovre injections at 6-8 week intervals prior to enrollment are part of the inclusion criteria. During the study, participants will undergo various eye imaging assessments such as OCT and FAF to monitor lesion size and progression. Researchers will evaluate changes in lesions at month 12 compared to baseline. Safety and tolerability will be closely monitored through laboratory tests, clinical evaluations, and vaccination status requirements. The study duration includes regular visits for treatment administration and monitoring over at least one year.

Researchers are evaluating corneal endothelial cells in people aged 50 and older who have neovascular age-related macular degeneration (nAMD). The study focuses on participants treated with the Port Delivery System (PDS) refilled every 24 weeks. This Phase IV, open-label trial aims to understand changes in corneal endothelial cell density over time in the eye receiving treatment compared to the fellow eye. The study involves delivering ranibizumab 100 mg/mL via the PDS implant. Supplemental treatment with intravitreal injections of ranibizumab (0.5 mg of a 10 mg/mL formulation) in the study eye may be given if needed. If participants stop the study treatment, they may receive intravitreal ranibizumab injections based on the investigator's judgment. Treatment and monitoring occur over at least 48 weeks. Participants will undergo detailed eye examinations including specular microscopy to measure corneal endothelial cell density at baseline and week 48. Historical visual acuity and imaging data will be reviewed. Researchers will monitor safety, disease activity, and treatment response through visual acuity assessments, optical coherence tomography, and other imaging techniques. The main outcome is the percent change in corneal endothelial cell density in the treated eye compared to the fellow eye after 48 weeks.

Researchers are evaluating the effectiveness and safety of several treatment combinations in people with metastatic or inoperable locally advanced breast cancer. This study includes multiple groups based on breast cancer subtypes and prior treatments, such as triple-negative breast cancer (TNBC) with or without prior therapy, and hormone receptor-positive or HER2-positive cancers with specific genetic mutations. The study is designed in two stages, with participants assigned to different treatment arms in the first stage, and some eligible participants continuing to a second stage if their disease progresses or they experience side effects. The treatments studied include various drugs given alone or in combination, such as oral medications like Capecitabine and Ipatasertib, intravenous antibodies like Atezolizumab and Trastuzumab Deruxtecan, and chemotherapy agents like Gemcitabine with Carboplatin or Eribulin. Dosing schedules vary by drug and combination, with cycles typically lasting 21 or 28 days. Some drugs are administered orally daily or on specific days, while others are given by intravenous infusion or subcutaneous injection. Participants will undergo regular assessments including scans and tumor biopsies to measure disease response and monitor safety. Researchers will collect tumor samples for biomarker analysis and perform laboratory tests to check organ function. The main outcome measured is the objective response rate, tracked from baseline until disease progression or loss of clinical benefit, which could be up to about 10 years. Participants must be able to comply with study procedures and will be monitored closely throughout their participation.

Researchers are studying the effects of two experimental drugs, pozelimab and cemdisiran, in adults aged 50 to 85 who have Geographic Atrophy (GA) caused by Age-related Macular Degeneration (AMD), a condition that affects central vision. The study aims to compare how quickly GA progresses in patients treated with cemdisiran alone, a combination of pozelimab and cemdisiran, or a placebo. Additional goals include monitoring possible side effects, measuring drug levels in the blood, and checking for antibodies that might reduce drug effectiveness or cause side effects. Participants receive subcutaneous injections of either pozelimab combined with cemdisiran, cemdisiran alone, or a placebo. The study is randomized, double-masked, and placebo-controlled, conducted at multiple centers. Treatment schedules and dosing are managed as described in the protocol, with vaccinations for meningococcal and pneumococcal infections required prior to participation. Throughout the study, participants undergo regular clinic visits where eye imaging using Fundus Autofluorescence (FAF) tracks the progression of GA lesion area over 52 weeks. Researchers also monitor safety, side effects, and immune responses, ensuring adherence to study procedures. The main outcome measured is the growth rate of the GA lesion area over one year, helping to evaluate the potential benefits and risks of the study drugs.

Researchers are evaluating the safety and effects of a medicine called disitamab vedotin for adults with advanced breast cancer that is hard to treat and has spread in the body. This study focuses on participants whose tumors express HER2 and who have received previous treatments for their advanced breast cancer. The goal is to understand how well this medicine works and its safety in these patients through a Phase 1b/2 open-label study. All participants will receive disitamab vedotin intravenously (IV) once every two weeks at the study clinic. They will continue the treatment until they or their doctor decide to stop, which could be due to cancer progression, side effects, or personal choice. During treatment, study visits occur every two weeks. After stopping treatment, participants will have follow-up visits about every six weeks, and later follow-up phone calls approximately every twelve weeks. Participants will undergo evaluations including assessments of their cancer response by the study doctors, following recognized criteria. The study team will monitor the participants for up to about two years or until their disease progresses or they pass away. This includes safety monitoring and collecting information about the medicine’s effects to determine its safety and effectiveness.

Researchers are evaluating whether tucatinib combined with trastuzumab and mFOLFOX6 works better than the standard treatments for people with HER2 positive metastatic colorectal cancer, which is cancer that has spread or cannot be removed by surgery. This phase 3 study also aims to identify the side effects that may occur with this drug combination. Participants must have HER2 positive disease confirmed by testing and measurable cancer according to specific criteria. Participants will be randomly assigned to one of two groups. One group will receive tucatinib taken orally twice daily along with intravenous trastuzumab and the mFOLFOX6 chemotherapy regimen, which includes oxaliplatin, leucovorin or levoleucovorin, and fluorouracil given by IV every two weeks. The other group will receive standard care, which could be mFOLFOX6 alone or combined with either bevacizumab or cetuximab, both given by IV on specific schedules. Treatment continues as per the study protocol. During the study, participants will be monitored for progression-free survival up to about three years using imaging reviewed by independent experts. Researchers will assess side effects and disease response. Participants must be able to provide tumor tissue samples for testing and have a good performance status. The study includes brain imaging to check for metastases and monitors safety closely throughout the treatment period.

Researchers are evaluating two surgical procedures, bilateral salpingectomy and bilateral salpingo-oophorectomy, to see how well they reduce the risk of ovarian cancer in women who have BRCA1 gene mutations. The study aims to determine if removing just the fallopian tubes (bilateral salpingectomy) is almost as effective as removing both the fallopian tubes and ovaries (bilateral salpingo-oophorectomy) in lowering ovarian cancer risk. This trial also assesses symptoms related to estrogen loss, quality of life, sexual function, cancer-related distress, decision-making about surgery, and treatment side effects in these patients. Participants choose between two groups: one group undergoes bilateral salpingectomy and may have their ovaries removed later, while the other group undergoes bilateral salpingo-oophorectomy. Both groups receive pelvic or transvaginal ultrasounds or pelvic MRI scans during screening, and blood samples are collected throughout the trial. Ancillary studies include quality-of-life assessments and questionnaires. The study also collects tissue and blood samples for future research. After surgery, participants have follow-up visits at 10 to 60 days, then at 6, 12, and 24 months, and annually for up to 20 years. Researchers monitor the time until any high-grade serous carcinomas develop, specifically ovarian, primary peritoneal, or fallopian tube cancers. They also track menopausal symptoms, sexual function, quality of life, cancer distress, medical decisions about surgery, and any adverse events during this long-term follow-up.

Researchers are evaluating the safety and effects of the medicine PF-07248144 combined with fulvestrant for treating hormone receptor-positive, HER2-negative advanced or metastatic breast cancer. This type of breast cancer involves cancer cells that grow in response to hormones like estrogen and progesterone but have little or no HER2 protein. The study focuses on people whose breast cancer worsened after treatment with cyclin dependent kinase (CDK) 4/6 inhibitor therapy. The trial is a phase 3, open-label, randomized study comparing PF-07248144 plus fulvestrant to other therapies chosen by doctors. Participants will receive either PF-07248144 tablets daily at home in 28-day cycles combined with fulvestrant injections at the clinic, or the usual treatment of everolimus tablets with endocrine therapy (either exemestane or fulvestrant). The study doctor will help decide the hormone therapy before starting treatment. The trial compares the experiences of those taking PF-07248144 plus fulvestrant with those receiving standard treatments to assess safety and effectiveness. During the study, researchers will monitor participants for disease progression or death, using blinded independent central review based on standard tumor response criteria. The main outcome measure is progression-free survival for up to about 2 years from randomization. Regular assessments, including clinical visits for injections and evaluations, will help track treatment effects and safety throughout the study.

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 the effectiveness of active surveillance and chemotherapy treatments in pediatric, adolescent, and adult patients with low risk and standard risk germ cell tumors. This phase III trial focuses on monitoring patients after tumor removal and comparing the outcomes of carboplatin-based versus cisplatin-based chemotherapy regimens. The study aims to maintain high overall survival rates for low risk patients and to compare event-free survival between the two chemotherapy options in standard risk patients. Additional objectives include assessing side effects such as hearing loss and neuropathy, and exploring tumor marker changes and other biological measures related to treatment outcomes. Patients with low risk stage I germ cell tumors undergo surgery followed by observation, with the option to transfer to standard risk treatment if the tumor recurs. Those with standard risk tumors are randomly assigned to one of four chemotherapy regimens combining bleomycin, etoposide, carboplatin, or cisplatin. Treatments are given intravenously on specific schedules every 21 days for up to 3 or 4 cycles, depending on the group. Throughout the trial, patients receive imaging scans, blood tests, tumor biopsies if needed, and pulmonary function tests to monitor treatment response and side effects. Participants are closely followed after treatment completion with regular visits every 2 months for the first year, then less frequently up to 10 years. Researchers collect data through imaging, blood samples, lung tests, and questionnaires to measure survival, disease recurrence, and side effects like hearing loss. The study also includes exploratory analyses of tumor markers and patient-reported outcomes to better understand treatment impacts and improve future care for germ cell tumor patients.
