The goal of this clinical trial is to learn if intratumoral administration of DNX-2401 works to treat recurrent and refractory high grade brain tumors in children and young adults. It will also learn about the safety of DNX-2401. The main questions it aims to answer are: * Does a single intratumoral administration of DNX-2401 elicit tumor response and improve survival? * Is a single intratumoral administration of DNX-2401 safe and well tolerated? Participants will: * Undergo surgery for tumor biopsy followed by a single intratumoral administration of DNX-2401 * Visit the clinic periodically for checkups and tests

Through this study funded by the Florida Cancer Innovation Fund, First Ascent will demonstrate state-wide feasibility of providing xDRIVE Functional Precision Medicine + Artificial Intelligence platform by assessing patient clinical benefit and health economics impacts. As this is a feasibility study, results will be returned to the physician and the physician may use the data to inform the next line of treatment. The investigator will run a prospective single-arm feasibility study providing the xDRIVE FPM AI platform to n = 210+ cancer patients throughout the state of Florida, especially those from underserved populations (pediatric patients and patients in Black, Brown, Hispanic, and rural communities).

To evaluate the safety and efficacy of Zeprumetostat-based combination therapy, selected according to genotyping results, in patients with primary refractory peripheral T-cell lymphoma (PTCL).

This is a single-arm, open, dose-increasing and dose-expanding phase I clinical trial to investigate the safety, tolerability and cytodynamic characteristics of MC-1-50 cell preparation, and to preliminatively observe the efficacy of MC-1-50 cell preparation in patients with refractory SLE, and to explore the applicable dose regimen for phase II clinical trials.

This study consists of two phases, phase Ib and phase II. The primary objective of phase Ib is to evaluate the safety and tolerability of multiple doses of daratumumab in patients with refractory aplastic anemia. The primary objective of phase II is to preliminarily assess the efficacy of multiple doses of daratumumab in patients with refractory aplastic anemia. Secondary objectives include evaluation of other efficacy endpoints, safety (phase II), and pharmacodynamic characteristics of multiple doses of daratumumab in these patients. The exploratory objective is to assess biological functional changes in peripheral blood and bone marrow before and after daratumumab treatment.

This study aims to evaluate the effect of subthreshold 577 nm micropulse laser photocoagulation in the treatment of initial and refractory cases of Center-Involved Diabetic Macular Edema.

Despite the progress in the therapy, Hodgkin's Lymphoma (HL) remains fatal for more than 15% of patients. Even in patients who are cured, the morbidity of therapy is substantial and long-lasting. New therapeutic agents are required therefore not only to further reduce mortality but also to alleviate morbidity. The majority of HL express the CD30 antigens. CD30 expression is routinely used for the diagnosis of HL. Preclinical observations support CD30 as a viable target of CAR-T therapy. This phase Ib/II study was conducted based on these observations. The purpose of this study is to determine the tolerability of ATLCAR.CD30.CCR4 cells in subjects with Hodgkin's Lymphoma and identify a recommended dose for further. This is a single-center, open-label phase Ib/II trial that uses a 3+3 design to identify a recommended phase 2 dose (RP2D) of ATLCAR.CD30.CCR4 cells in Hodgkin's Lymphoma. The phase II portion is designed to determine the PFS of ATLCAR.CD30.CCR4 in Hodgkin's Lymphoma. Subjects will be enrolled on 1 of 3 dose levels as determined by a 3+3 design. Up to 25 evaluable subjects may then be enrolled in the phase II portion of the study. Subjects may have cells procured to manufacture the ATLCAR.CD30.CCR4 cells if they meet eligibility for procurement. During the time period necessary to manufacture the ATLCAR.CD30.CCR4 cells, Subjects will be allowed to receive standard-of-care bridging therapy at the discretion of their local oncologist. Prior to cell infusion, subjects will undergo additional eligibility evaluations, and then if eligible, will undergo lymphodepletion followed by cell infusion 2-14 days later. Subjects will then be followed for 15 years as is required for studies involving gene transfer experiments.

This observational monocentric study aims to evaluate the long-term effectiveness and tolerance of percutaneous endoscopic caecostomy (PEC) in patients with chronic refractory constipation. Follow-up data will be collected through phone interviews and standardized quality of life questionnaires.

To study the optimal therapeutic strategies for salvage treatment of refractory/relapsed AML, and to clarify the effectiveness and safety of various salvage treatment options. A prospective, multicenter, platform-type study was conducted to explore the overall response rate, tolerability, and survival of patients with R/R AML with different treatment regimens.

This trial is exploratory research aimed at evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of RD13-02, a universal CD7 CAR T therapy, in subjects with relapsed/refractory severe aplastic anemia (SAA)

Retinoblastoma (RB) is the most common intraocular malignancy in children, accounting for approximately 11% of all cancers diagnosed in children under the age of one. Although its incidence is relatively low-about 1 in 15,000 to 20,000 live births-RB has a high risk of intracranial metastasis via the optic nerve, often leading to poor prognosis in advanced cases. Recent advances in administration routes, such as intravitreal and intra-arterial chemotherapy, have significantly improved eye preservation rates. However, these strategies are limited by cumulative retinal toxicity and drug resistance. In refractory cases, enucleation remains the only definitive treatment to prevent extraocular spread and death. In light of these challenges, current research efforts are focused on developing novel targeted therapies that enhance anti-tumor efficacy while minimizing local toxicity. In this context, we introduce a first-in-class siRNA-based drug targeting NUDT21, which promotes tumor regression by modulating the 3'UTR tail of SMC1A, thereby suppressing tumor cell proliferation. Importantly, the siRNA drug selectively targets tumor cells, offering a favorable safety profile compared to conventional chemotherapeutic regimens. Given that both the target (NUDT21) and the mode of administration (intraocular siRNA injection) are novel in retinoblastoma treatment, there is an urgent need for early-phase investigator-initiated clinical research. This study is therefore designed to assess the short-term safety and preliminary efficacy of NUDT21 siRNA in patients with refractory retinoblastoma, and to provide an evidence base for future large-scale clinical trials.

This is a single arm, open-label, dose escalation clinical study to evaluate the safety and tolerability of autologouschimeric antigen receptor T (CAR-T) cells targeting CD19/CD22/BCMA in patients with relapsed/refractory multiple myeloma.
