Researchers are evaluating KB801, a special virus-based treatment designed to deliver human nerve growth factor to the corneas of people with Stage 2 or 3 neurotrophic keratitis, a condition that affects corneal healing. This Phase 12 study is designed to assess the safety, tolerability, and early signs of effectiveness of KB801 compared to a placebo. The study is double-masked and placebo-controlled, involving participants with persistent corneal epithelial defects that have not improved. Participants will be randomly assigned to receive either KB801 or a placebo, applied topically to the affected eye once daily for 8 weeks. After completing treatment, they will return for a follow-up visit two weeks later to check on safety and the stability of corneal healing. Further safety monitoring will take place every three months for about one year while participants remain in the study. Throughout the trial, participants will undergo regular assessments to monitor safety, including tracking any adverse events. Researchers will evaluate healing of the corneal defects using specific measurements over 8 to 10 weeks. Safety follow-up visits extend through approximately one year to observe the durability of treatment effects and overall tolerability. Participants can expect regular visits for examinations and safety monitoring during this time.

Researchers are evaluating the effects of MELT-300 on procedural sedation in adults undergoing cataract extraction with lens replacement CELR. This Phase 3 clinical trial aims to compare MELT-300 with a placebo and an active comparator, sublingual midazolam, to assess the contribution of ketamine in the combined drug product. The study focuses on the effectiveness and safety of MELT-300 during and after cataract surgery. Participants will be randomly assigned to one of three groups MELT-300 a sublingual tablet containing 3 mg midazolam and 50 mg ketamine, midazolam alone 3 mg sublingual tablet, or a placebo tablet. They will receive a single dose of the assigned medication approximately 30 minutes before surgery without food or water. The surgery will be performed under topical anesthesia, and the study medication effects will be assessed before, during, and after the procedure. Participants will be admitted on the day of surgery and monitored throughout. Researchers will assess sedation levels, the need for additional sedation or pain medication, and the ability to complete surgery. Safety will be tracked through adverse event monitoring, vital signs, and physical exams at baseline, during surgery, and up to three days after medication. The primary outcome measured is the percentage of participants achieving successful procedural sedation at various time points on the day of surgery.

This research aims to evaluate patient and surgeon-reported outcomes for individuals undergoing blepharoplasty using a device called Ziplyft. The study focuses on measuring patient satisfaction with facial appearance and eyes, surgeon satisfaction and efficiency, bruising, eyelid symmetry, wound closure success with tissue adhesive, and case time. The study is interventional and monitors these outcomes over a 3-month period following the procedure. Participants will receive treatment with Ziplyft, a Class 1, 510k exempt device designed to remove excess unwanted eyelid skin through a novel surgical method. The procedure is performed once, followed by regular follow-up visits extending up to 3 months to assess various outcomes including the success of wound closure and improvements in eyelid appearance and symmetry. Throughout the study, participants will attend scheduled visits for evaluations that include patient and surgeon feedback, assessments of bruising and eyelid symmetry, and measurements related to wound healing and procedure efficiency. Researchers will track these factors from enrollment through the final visit at 3 months to understand the devices performance and participant satisfaction. Participants are also monitored for any adverse effects and are expected to comply with study instructions and follow-up visits during this time.

Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.
