The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Know the risks and potential benefits of clinical studies and talk to your health care provider before participating.
Read our disclaimer for details.
This is an expanded access program (EAP) for eligible participants. This program is designed to provide continued access to TRx0237 to individual patients with mild-moderate Alzheimer's disease who do not qualify for participation in an ongoing clinical trial. Eligible participants must have previously completed participation in a clinical trial of TRx0237 conducted by TauRx, among other criteria.
Choosing to participate in a study is an important personal decision. Talk with your doctor and family members or friends about deciding to join a study. To learn more about this study, you or your doctor may contact the study research staff using the contacts provided below. For general information, Learn About Clinical Studies.
Ages Eligible for Study:
Child, Adult, Older Adult
Sexes Eligible for Study:
Mild to moderate Alzheimer's disease, as confirmed by a cognitive assessment
Clinical benefit of continued access to TRx0237 is expected to outweigh any perceived risk
The patient has the ability to travel to the named clinic for regularly scheduled visits.
The patient and/or his/her legal guardian have been informed of the potential risks and obligations and have given written informed consent for continued treatment consistent with local requirements.
The patient is not participating in a clinical trial of another investigational drug.
A female patient of child-bearing potential must use adequate birth control (as defined by the protocol) for at least 90 days before beginning treatment and agree to continue its use whilst on treatment and for 30 days after the last dose of TRx0237.
Swallowing difficulties which prevent taking the medication whole as instructed.
Patients, who in the opinion of the treating physician, are unable to comply with this study protocol or have health concerns that may increase risk.
Patients who enrolled in a previous TRx0237 clinical trial and either did not complete the clinical trial or had a significant treatment-related adverse event that could cause an undue risk
Current use of acetylcholinesterase inhibitors and/or memantine
Use of drugs for which there is a warning or precaution in the labeling about methemoglobinemia at approved doses (e.g., dapsone, local anesthetics such as benzocaine used chronically, primaquine and related antimalarials)
Use of clozapine or olanzapine
Clinically significant respiratory failure (e.g., caused by chronic obstructive pulmonary disease, bronchial asthma, lung fibrosis, or other disease)
History of clinically significant hematological abnormality (including hemoglobinopathy, myelodysplastic syndrome, hemolytic anemia, or splenectomy) or hemoglobin value (confirmed upon repeat) below age/sex appropriate laboratory lower limit of normal
Creatinine clearance <30 mL/min
Clinically significant alanine transaminase (3×the upper limit of normal [ULN]) and/or bilirubin (2×ULN) values
Clinically significant cardiovascular disease (e.g., acute coronary syndrome or symptoms consistent with angina pectoris, signs or symptoms of clinical heart failure, atrial fibrillation that is not currently controlled, QTcF [QT corrected for heart rate using Fridericia's formula] of >460 msec in males or >470 msec in females, poorly controlled hypertension, tachycardia, or bradycardia)
