Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Formulation	NCT01889173 ↗	Comparative Pharmacokinetics and Safety of 3 Different Formulations of TNX-102 2.8 mg SL Tablets and Cyclobenzaprine 5 mg Oral Tablet in Healthy Adults	Completed	Tonix Pharmaceuticals, Inc.	Phase 1	2013-06-01	Very low dose (VLD) cyclobenzaprine at bedtime has shown promise as a treatment for fibromyalgia, but the chemistry of cyclobenzaprine requires new formulation technology for bedtime use. The present trial is designed to assess the safety and tolerability of 3 different formulations of TNX-102 2.8 mg SL Tablets (a new formulation of cyclobenzaprine designed to result in increased dosage precision and decreased potential for morning grogginess) and to compare the bio-availability of 3 different formulations of TNX-102 2.8 mg SL Tablets (TNX-102 with potassium phosphate, TNX-102-B with sodium phosphate, and TNX-102-C with trisodium citrate) to that of cyclobenzaprine (5 mg tablets).
OTC	NCT03707795 ↗	Treatment of FUS-Related ALS With Betamethasone - The TRANSLATE Study	Completed	Edward Kasaraskis	Early Phase 1	2017-08-21	By doing this study the investigator hopes to learn more about a potential cause of amyotrophic lateral sclerosis (ALS) called "oxidative stress". Oxidative stress is essentially an imbalance between the production of certain chemicals in the body called "free radicals" and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants. It is thought that factors such as environmental exposure (chemicals and lead), diet, smoking,alcohol consumption, physical activity and psychological stress cause oxidative stress to occur inside the body. By doing this study, the investigator hopes to learn whether the FDA-approved steroid medication called Betamethasone will restore overall antioxidant activity fALS patients with mutations in the Fused in Sarcoma gene (FUS gene). Participants who agree to take part in this research study, agree to the following responsibilities: - Attend all scheduled visits - Notify the study doctor of any illnesses, unexpected or troublesome side effects, or any other medical problems that occur during the study - Be completely honest with their answers to all questions - Check with the study doctor before taking any new medications, whether prescribed or "over the counter," even vitamins and herbal supplements.

NCT00074165 ↗	Treating Patients With Recurrent PCNSL With Carboplatin/BBBD and Adding Rituxan To The Treatment Regimen	Terminated	National Cancer Institute (NCI)	Phase 2	2003-01-01	RATIONALE: Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, etoposide, etoposide phosphate, and cytarabine, use different ways to stop cancer cells from dividing so they stop growing or die. Osmotic blood-brain barrier disruption uses certain drugs to open the blood vessels around the brain and allow anticancer substances to be delivered directly to the brain tumor. Chemoprotective drugs such as sodium thiosulfate may protect normal cells from the side effects of carboplatin-based chemotherapy. Combining rituximab with chemotherapy given with osmotic blood-brain barrier disruption plus sodium thiosulfate may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combining rituximab with combination chemotherapy given with osmotic blood-brain barrier disruption plus sodium thiosulfate in treating patients who have refractory or recurrent primary CNS lymphoma.

Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, and etoposide phosphate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Sodium thiosulfate may prevent low platelet counts in patients receiving chemotherapy. It is not yet known whether combination chemotherapy is more effective with or without sodium thiosulfate in preventing low platelet count during treatment for brain tumors.
