Study Endpoints

Primary Endpoints

Change from Baseline to Week 48 in the sum of the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II score and Part III score [Efficacy]
From baseline to Week 48

Change from Baseline to Week 48 in the sum of the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II score and Part III score assessed in the practically defined OFF state. MDS-UPDRS is a multimodal scale assessing impairment and disability consisting of four parts. Part II assesses motor experiences of daily living (Range 0-52). It contains 13 questions which are to be rated by the patient and/or caregiver. Part III assesses the motor signs of PD and is rated by the investigator (Range 0-132). Part III contains 33 scores based on 18 items. For each question a numeric score is assigned between 0-4, where 0 = Normal, 1 = Slight, 2 = Mild, 3 = Moderate, 4 = Severe. A higher score indicates more severe symptoms of PD.

Low Dose GT-02287DRUGSachets containing 400 mg/day or 600 mg/day of active (GT-02287), depending on the participant's body weight. Each daily dose will be prepared as an oral suspension by mixing the content of 1 sachet with the vehicle (supplied in an amber glass bottle) and the requisite volume of tap water.
High Dose GT-02287DRUGSachets containing 800 mg/day or 1000 mg/day of active (GT-02287), depending on the participant's body weight. Each daily dose will be prepared as an oral suspension by mixing the content of 1 sachet with the vehicle (supplied in an amber glass bottle) and the requisite volume of tap water.
PlaceboDRUGSachets containing 420 to 1200 mg of MAS indistinguishable from the active sachets. Each daily dose will be prepared as an oral suspension by mixing the content of 1 sachet with the vehicle (supplied in an amber glass bottle) and the requisite volume of tap water.

Frequently asked questions about GT-02287

What is GT-02287 used for?

GT-02287 is an investigational small molecule being developed for the treatment of Parkinson disease. It is a Phase 2 candidate in the neurology therapeutic area, and it is not yet approved for any use. Gain Therapeutics is studying it in early Parkinson disease as well as in a separate safety and pharmacology study.

What does GT-02287 target?

GT-02287 targets GCase, a lysosomal enzyme also known as glucocerebrosidase. By acting on this lysosomal enzyme, the small molecule is designed to address GCase-related biology in Parkinson disease. GCase is the molecular target named for this investigational compound.

Who is developing GT-02287?

GT-02287 is being developed by Gain Therapeutics, Inc., which trades on the Nasdaq under the ticker GANX. Gain Therapeutics is the sponsor behind the clinical program evaluating the compound in Parkinson disease, including a Phase 2 trial and a Phase 1 study.

What phase is GT-02287 in?

GT-02287 is in Phase 2 development for Parkinson disease. It is an investigational drug and has not been approved by the FDA. The Phase 2 trial is not yet recruiting, while a Phase 1 safety, tolerability, pharmacokinetics, and pharmacodynamics study is currently recruiting.

What clinical trials is GT-02287 in?

GT-02287 is being studied in two trials. NCT07280299 is a Phase 2 trial evaluating efficacy, safety, tolerability, and biomarker effects in early Parkinson disease, with planned enrollment of 111 participants. NCT06732180 is a Phase 1 trial assessing safety, tolerability, pharmacokinetics, and pharmacodynamics in Parkinson disease, enrolling 20 participants in Australia.

Is GT-02287 the same as Low Dose GT-02287?

Yes. Low Dose GT-02287 is another name used for GT-02287, so searches for either term refer to the same investigational compound. Both names point to the GCase-targeting small molecule that Gain Therapeutics is developing for Parkinson disease in Phase 2 and Phase 1 clinical trials.
