Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

Researchers are testing an experimental oral tablet called MT101-5 in people recently diagnosed with Parkinson's disease. The trial enrolls about 120 adults aged 30 to 79 who have had Parkinson's for two years or less and are either not yet on medication or on stable doses. Participants receive one of two daily doses of MT101-5 or a placebo for a set period. The main goal is to check safety and tolerability, while secondary measures track movement symptoms and daily function.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MT101-5, an experimental oral tablet
What this could lead to
If MT101-5 proves safe and tolerable, it could become a new oral option for people in the early stages of Parkinson's disease.
What could go wrong
This is a mid-stage trial with 120 participants, so safety and tolerability results may not hold in larger groups. Many Parkinson's drugs that show promise in Phase II fail in later testing.

Inclusion Criteria Subjects will be eligible for enrollment in the study only if they meet ALL of the following criteria: 1. Male or female subjects who are between 30 and 79 years old inclusive with a clinical diagnosis of Parkinson's disease as per UK Brain Bank Criteria for two (2) years or less at screening. 2. Hoehn and Yahr I or II at screening. 3. Subjects who are newly diagnosed \& currently not on any Parkinson's disease medication (or) subjects who are on stable doses for at least 4 weeks prior to screening on Amantadine or anticholinergics for treatment of Parkinson's disease (1) Note: Subjects that had anti-parkinsonian medication (including levodopa, dopamine agonists, entacapone and monoamine oxidase-B inhibitors) discontinued at least 60 days prior to screening, e.g., for intolerance, may be considered eligible if all other eligibility requirements are met. 4. Without clinically significant abnormalities in physical exam, neurological exam and laboratory assessments (urine/blood routine, biochemical tests and ECG) which would exclude the subject from the study in the opinion of the Investigator. For aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) the screening levels should be ≤ 2 times upper limit normal. 5. Subject is capable of providing informed consent and is willing to sign the ICF prior to study Screening and agrees to comply with the study protocol requirements. Exclusion Criteria Subjects will be eligible for enrollment in the study only if they meet NONE of the following criteria: 1. Subject has an atypical parkinsonian syndrome or secondary parkinsonism (e.g., due to drugs, metabolic neurogenetic disorders, encephalitis, cerebrovascular disease or degenerative disease). 2. Subjects with history of neurosurgical intervention for Parkinson's disease. 3. Subjects who meet the DSM-V criteria at screening for bipolar disorder, major depressive disorder, psychotic disorders, or any other comorbid mental disorders that in the opinion of the Investigator may interfere with study conduct and results interpretation. 4. Subjects with clinical diagnosis of dementia (MMSE score \<24) as determined by the investigator using Mini-Mental State Examination (MMSE). 5. Female subjects who are pregnant or breast feeding. 6. Initiation of any anti-parkinsonian medication (including levodopa, dopamine agonists, entacapone and monoamine oxidase-B inhibitors) for the duration of the trial. 7. Initiation of Amantadine or anticholinergics for newly diagnosed subjects or change in the dosage of Amantadine or anticholinergics during the trial for subjects who were on stable doses for 4 weeks prior to screening. 8. Medical or recreational use of marijuana or THC-containing compounds within 3 months of screening visit and for the duration of the trial. 9. Subjects who used investigational drugs or devices within 60 days prior to screening or investigational biologics within the last 6 months prior to screening. 10. Subjects with a clinically significant medical or surgical condition, including major surgeries within 28 days prior to enrollment. 11. The subject has a known allergy or hypersensitivity to any component of the formulation. 12. The subject has a history of alcohol abuse (defined as an alcohol intake more than 21 units per week) or a history of drug abuse within the 6 months before study drug administration, or a history of substance abuse deemed significant by the investigator. A unit of alcohol is defined as 240 mL of beer, 120 mL of wine, or 1 single shot of spirits. 13. Women of child-bearing age who are sexually active but decline to take proper contraceptive measures during the study period Note: To be eligible for the study, Women of childbearing potential (WOCBP) and Women not of childbearing potential are eligible to participate. Both women of childbearing potential and women of no childbearing potential should use an approved method of birth control and agrees to continue to use this method for the duration of the study (and for 30 days after taking the last dose of investigational product). Acceptable methods of contraception include abstinence, female subject/partner's use of hormonal contraceptive (oral, implanted, or injected) in conjunction with a barrier method (WOCBP only), female subject/partner's use of an intrauterine device (IUD), or if the female subject/partner is surgically sterile or 2 years post-menopausal. All male subjects/partners of WOCBP must agree to consistently and correctly use a condom for the duration of the study and for 30 days after taking the study drug. In addition, subjects may not donate ova or donate sperm for the duration of the study and for 30 days after taking the last dose investigational product.
