Safety Evaluation of Intravenous Talineuren (TLN) in Parkinson's Disease-affected Patients

Phase 1
Active, not recruiting
Conditions
Parkinson Disease

Registration Number
NCT04976127
Lead Sponsor
InnoMedica Schweiz AG
Brief Summary

This study is an open-label, single ascending dose escalation followed by a multiple administration dose at the maximal suitable dose (MSD). The investigational Medicinal Product (IMP) is given as an add-on therapy.

Talineuren consists of GM1 (monosialotetrahexosylganglioside), the pharmacologically active ingredient, associated with a proprietary lipid formulation assembled as liposomes.

The primary objective is to demonstrate the safety of TLN administration intravenously in Parkinson patients.

Secondary objectives are the determination of the maximal suitable dose based on the safety profile and preliminary efficacy, as well as the determination of the pharmacokinetics (PK) profile.

Detailed Description

The ganglioside lipid GM1 has been described in the literature as a neuroprotective agent.

Several clinical studies have shown that GM1 improves the condition of Parkinson's disease patients.

Talineuren consists of the pharmacologically active ingredient GM1, associated with a proprietary lipid formulation assembled as liposomes. Talineuren has been developed to improve the delivery and bioavailability of GM1.

The primary objective of this trial is to demonstrate the feasibility and safety of intravenous Talineuren administration in Parkinson's disease patients.

The secondary objectives are:

* The determination of the recommended phase 2 dose based on the safety profile and preliminary efficacy.

* The determination of the pharmacokinetics (PK) profile.

This trial aims to investigate the safety of the novel formulation of GM1, Talineuren.

To that extent a three-part trial was designed: Part 1- Dose escalation Part 2- Dose consolidation Part 3- Dose consolidation with intrapatient dosing

Part 1- rapid dose escalation scheme from 6 mg to 720 mg of Talineuren formulated GM1 in 3 patients. Optional treatment prolongations for 8 weeks (Amendment 1), 16 weeks (Amendment 2), 8 months (Amendment 3), 4 months (Amendment 4), and 12 months (Amendment 5).

Part 2- multiple dosing of Talineuren over 8 weeks in 9 patients to validate the safety profile of the maximum suitable dose. Optional treatment prolongations for 16 weeks (Amendment 2), 8 months (Amendment 3), 4 months (Amendment 4), and 12 months (Amendment 5).

Part 3- rapid dose escalation scheme from 6 mg to 720 mg of Talineuren followed by multiple doses of 720mg Talineuren for up to 8 months in 10 patients (Amendment 3).
