Phenylketonuria (PKU) is an autosomal recessive inborn error of L-phenylalanine (L-Phe) metabolism which is caused by deleterious variants in the gene coding for the phenylalanine hydroxylase (PAH) enzyme. The PAH enzyme catalyses the conversion of phenylalanine (Phe) to tyrosine (Tyr), a precursor of several neurotransmitters, hormones, skin, hair, and eye pigments. Elevated concentration of Phe and secondary metabolites and lower Tyr concentration in blood and in brain cause degenerative neuropathology, neurological symptoms, and intellectual deficits, together with poorly or non-pigmented skin and hair, and musty odor which are characteristic in untreated patients with PKU (1, 2).
This Phase 1/Phase 2 study is designed to assess the safety and efficacy of escalating doses of SAR444836 treatment in participants with PKU. The data collected will help to evaluate whether this adeno-associated virus (AAV) vector which delivers the functional human PAH gene into hepatocytes is effective in the treatment of PKU disease. The expression of PAH gene in hepatocytes is expected to provide steady low plasma levels of Phe similar to those observed in healthy individuals, preventing marked fluctuations caused by normal dietary protein intake.
The study is divided into 2 parts including a dose escalation phase (Stage 1A) and a dose expansion phase (Stage 1B).

The APEX 3D™ Total Ankle Replacement System is intended to reduce pain and restore motion to a failing ankle joint due to rheumatoid, post-traumatic, or degenerative arthritis. In 2020, the APEX 3D™ Total Ankle Replacement System received 510(K) clearance from the FDA, demonstrating that the device is marketed as safe and effective. The primary objective of this research study is to determine implant survivorship. Enrollment is expected to take approximately one to two years. All subjects will be followed for ten years post-operatively. Study follow-up visits will occur at 6-weeks, 6-months, and annually for ten years after surgery. During the pre-operative visit and each follow-up visit, subjects will be asked to complete a series of questionnaires that assess their levels of pain, function, mobility, and quality of life. Comparison of pre-operative scores to post-operative scores can be used to assess the improvement in patient function, thus supporting the benefit and clinical performance of the intervention. As with any clinical research study, there is a risk of unintended personal health information disclosure.

This study is an open label extension study for those who participated in the ION 682884-CS2 clinical trial for transthyretin-mediated amyloid cardiomyopathy (ATTR-CM). ATTR-CM is a disease caused by change in a protein called transthyretin (TTR) which can result in a build up of this protein in parts of the body including the heart. This build up is called an amyloid deposit, and when this occurs in the heart it can lead to a condition called cardiomyopathy. This study involves the medication eplontersen, which is considered investigational meaning it is not approved for commercial use by the Food and Drug Administration (FDA). Eplontersen is aimed at preventing production of the TTR protein to slow or reverse disease progression. Eplontersen is given as an injection under the skin in the upper arm, stomach or thigh. This study will last about 3 1/2 years and include 16 clinic visits. Study procedures include physical exams, blood work, questionnaires, hall walk tests, electrocardiograms (tracing of the heart's electrical activity), echocardiogram (ultrasound test of the heart) and taking a Vitamin A supplement.

The study will test OATD-01, an experimental medicine, for the first time in patients with pulmonary sarcoidosis (swollen tissue in the lungs). The study goal is to evaluate OATD-01 in the reduction of inflammation and assessing OATD-01 safety.

Everyone who participates in this study will receive OATD-01 or matching placebo (inactive mock tablet). Subjects will be randomly assigned to receive either OATD-01 or placebo for 12 weeks.

The study will run in several hospitals or outpatient clinics, in different countries in Europe and in the USA. In this study, there will be about 98 study subjects in total.

For all patients whether taking OATD-01 or matching placebo, there will be a screening period, a treatment period which will commence after randomization has taken place and will last for 12 weeks and then a follow up visit approximately 4 weeks post last dose of OATD-01.

The total duration of the study is 18 weeks.

The purpose of this study is to evaluate ABBV-400 in subjects with select solid tumors. This study will consist of
multiple cohorts with each cohort investigating ABBV-400 at 3 mg/kg Q3W.
The study will consist of a Screening, a Treatment, and a Follow-Up period.
All screening procedures must be performed within 28 days of first dose with the exception of tumor
tissue biopsy, which may occur during screening or any time after disease progression on the most
recent treatment. Subjects will continue treatment with ABBV-400 3 mg/kg Q3W until documented disease progression,
intolerable toxicity, or the subject meets other protocol criteria for discontinuation of treatment
(whichever occurs first). The maximum treatment duration will be 2 years.

The purpose of this study is to evaluate the effectiveness of varenicline (sometimes known as Chantix) compared to placebo (an inactive substance) for the treatment of cigarettes and cannabis (marijuana). Varenicline is not FDA approved for the combination treatment of cigarette abstinence and cannabis reduction or abstinence. All participants will also receive counseling and access to online treatment modules during a quit attempt for cigarettes and a reduction attempt for cannabis. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely; therefore, no in-person visits are needed.

To qualify, participants must be 18 or older, live in South Carolina, use cigarettes and cannabis, and are interested in quitting cigarettes and reducing cannabis.

This phase I trial will determine the maximum tolerated dose of lenalidomide when given in combination with high-dose systemic methotrexate and rituximab, with or without nivolumab, as induction treatment of primary central nervous system lymphoma. In addition, whether the combination of drugs can extend the control of CNS lymphoma by being used as maintenance (prolonged treatment) after control is achieved with the initial chemotherapy regimen (induction) will be judged. If decided to take part in the study, participants will complete pre-study testing, and if allowed to participate in study different people will get different doses of the study drug lenalidomide during induction chemotherapy. If the drug does not cause serious side effects, the next group of people in the study will get a higher dose, and the doses will continue to increase for every new group until people have serious side effects that require the dose to be lower. Lenalidomide will be taken by mouth on days 5 to 14 of each induction cycle. Once the dose of lenalidomide is found, the next group of people in the study will receive nivolumab in combination with the other drugs (methotrexate, rituximab, and lenalidomide). The first drug administered in each cycle is rituximab, which is given as an intravenous infusion typically in the infusion center. The day after rituximab, participants will be admitted to the hospital for the infusion of methotrexate. Enrolled participants that present benefit after induction will receive lenalidomide and nivolumab as prolonged therapy (maintenance) for an additional 12 months (12 cycles and each cycle is 28 days) or until the disease gets worse or the side effects become too severe. After treatment is completed the study doctor will continue to follow up on participants condition for 2 years to observe side effects. After 2 years the doctor will continue to follow up either in clinic or by phone for up to 5 years after registration. The most common side effects known are kidney damage, infusion reaction, blood clots, birth defects, immune toxicity, fever and infections, and there may be some risks that the study doctor is not aware of yet. Once the combination is proven safe, this study will allow for future studies to determine whether the combination of these four drugs can improve the response to treatment and help increase the understanding of their use in primary CNS lymphoma treatment. It is unclear whether these drugs will help participants live longer than the usual approach alone.

In the effort to find better treatments for moderate acne, which often relies on long-term antibiotic use, researchers are exploring alternative options. While isotretinoin, a vitamin A derivative, is highly effective for severe acne, its side effects limit its use for milder cases. A recent study from our institution investigated a new approach: weekly isotretinoin dosing. The results were promising, with acne improvement and no major side effects. This suggests that weekly isotretinoin could be a successful alternative for moderate acne in both males and females. To validate these findings, we propose a randomized controlled trial comparing weekly isotretinoin to daily doxycycline over four months. This study could confirm the safety and effectiveness of weekly isotretinoin, as well as shed light on patient satisfaction, and long-term results compared to standard antibiotics. This research may offer a breakthrough in treating moderate acne while addressing concerns about antibiotic overuse.

The Patient Registry for Participation in Aging/Alzheimer's Research (PREPARE) is a database of individuals with Mild Cognitive Impairment who are interested in participating in research on aging/Alzheimer's disease and related dementias conducted at the Medical University of South Carolina (MUSC). PREPARE will connect MUSC researchers with potential participants so they can provide information about studies for which they may be eligible. PREPARE will also collect survey data from people with Mild Cognitive Impairment and their study partners to better understand the impact of this condition on daily functioning.

Tetra Discovery Partners, Inc. has two studies that are recruiting males aged 9 to 45 to participate in a treatment clinical trial for Fragile X Syndrome. The treatment, called BPN14770, is a phosphodiesterase inhibitor that has the potential to address cognitive and neurological impairment in those with Fragile X Syndrome.

BPN14770-CNS-301 is a clinical trial for males aged 18 to 45 with Fragile X Syndrome. It is double-blind, meaning that neither the study doctor nor the enrolled participants know whether or not they are receiving study drug or placebo. A placebo is an inactive material that looks like the study drug, but does not contain any active study drug.

The main goals of this study are to learn how well the study drug works and how safe the study drug is compared with placebo.

After completing the double-blind study, participants have the opportunity to enroll in the open-label extension of this clinical trial, called BPN14770-CNS-302; "open-label" means that the study doctor and participants are all aware that participants are definitely getting the study medication.
