This open-label research study will evaluate two investigational therapies, TransCon TLR7/8 Agonist and TransCon IL-2 β/γ, which are not approved by the U.S. Food and Drug Administration (FDA). Pembrolizumab, an FDA approved medication, also a study drug on this trial is given as standard of care for this type of cancer. This study begins with two study treatment groups, Groups A:TransCon TLR7/8 Agonist injected directed into the tumor once every 21 days and Group B: TransCon IL-2 β/γ which is given through a IV over 30 minutes once every 21 days. The surgery may occur after Cycle 2 of the medications at a scheduled time that the study doctor feels appropriate. Once 12 participants have completed study treatment, 6 in each group (A and B), an analysis will determine the continuation of the study. If it passes the criteria, the study will continue, and another study treatment group, Group C: Pembrolizumad alone given through an IV over 30 minutes once every 21 days, will open. Participants will be randomly assigned to one of the three groups. At the present time, limited information is available on the adverse side effects potentially related to TransCon IL-2 β/γ and TransCon TLR7/8. Very common side effects observed with TransCon IL-2 β/γ include changes with your immune system being stimulated, blood pressure, and heartbeat. Also flu-like symptoms (nausea, fever, and chills), changes in lung/liver/kidney function, and brain related symptoms including dizziness, weakness, confusion, difficulty speaking, and/or decreased brain function, which may become life-threatening. TransCon TLR7/8 Agonist requires more data collection to determine the extent of side effects in humans. At this time, there are no proven benefits in humans however, the animal studies have shown promising results. The national accrual goal for this study is 92 participants and MUSC projects to accrual approximately 5 participants per year over a span of 2 years.

This study is for those with Transthyretin (TTR) Amyloidosis with Cardiomyopathy or ATTR-CM. ATTR-CM is a condition where the heart muscle does not pump your blood through your body as it should because of build up of abnormal protein between the muscle fibers in your heart. The specific protein is called transthyretin amyloid (TTR). The study involves an investigational drug called NTLA-2001. Investigational means it is not approved for commercial sale or use by the Food and Drug Administration. This study is a randomized study meaning participants will be assigned by chance to receive NTLA-2001 or placebo. A placebo looks like the investigational drug but contains no active ingredient. In this study, two out of three participants are assigned to receive NTLA-2001 and one out of three will receive placebo. NTLA-2001 or placebo are given by intravenous (IV) infusion meaning in your vein.

NTLA-2001 consists of a gene editing system which can "knockout" the TTR gene and permanently change the DNA (deoxyribonucleic acid, which contains information that determines parts in traits such as eye color or height, that are passed on from parent to child) so the gene stops making the TTR protein.

This study will last at least 18 months and include up to 17 visits. Study related procedures include physical exams, blood work including genetic testing, eye exam, hall walk test, electrocardiograms (ECGs), echocardiogram (echo) and vitamin A supplement. Study risks include infusion related risks like headache, fever, chills, or increased liver enzymes. Other study related risks include genetic risks, loss of confidentiality and unknown risks.

A clinical research study is an investigation in humans of a potential medical treatment that is designed to discover or verify whether it works and is safe. This study will test an investigational drug called DF9001. "Investigational" means that it has not been approved by any health authority such as the United States Food and Drug Administration (FDA) or the European Medicines Agency (EMA). Information gathered from this study will be sent to the various health authorities.
The study has two parts: a Dose Escalation part and an Efficacy Expansion part. The main purpose of the Efficacy Expansion part of this study is to test whether the study drug (DF9001) works (if it causes cancer to shrink or disappear). The Dose Escalation part of this study's main purpose is to test different doses of the study drug by itself, and also in combination with a drug called nivolumab, an FDA approved drug. Some foreseeable risks associated with DF9001 include Diarrhea,
Skin problems, Nail changes, Eye problems, Inflammation of the lungs, intestines and liver, as well as unforeseen side effects that may occur. There is no direct benefit in participating in this study.

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.

This is a randomized, double-blind, parallel group, vehicle-controlled phase to evaluate the efficacy and safety of diacerein 1% ointment applied topically once daily for 8 weeks for the treatment of adult and pediatric (age ≥ 6 months) patients with generalized EBS. The duration of study participation is anticipated to be approximately ~16 to 20 weeks per patient consisting of a Screening Period of up to 4 weeks, a Treatment Period of 8 weeks and a No Treatment Follow-up Period of 8 weeks. Patients that complete this portion of the study will be eligible to participate in an open-label, 24-week extension phase to evaluate the long-term safety of diacerein 1% ointment for the treatment of generalized EBS.

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.

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.

This is an observational study that create a patient registry by collecting data, biosamples (blood and stool samples) on patients who have been diagnosed with Clostridiodes difficile (C difficile). The registry will include data about CDI episodes, CDI related symptoms, participant experience. The study will last 42 days and there will be 2-3 visits.

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 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.
