A Study to Evaluate the Safety, Tolerability and Efficacy of ILB in Patients With Amyotrophic Lateral Sclerosis

Phase 2

Terminated

• Conditions: Amyotrophic Lateral Sclerosis
• Interventions: Drug: ILB

• Registration Number: NCT03613571
• Lead Sponsor: TikoMed AB

Brief Summary

This is a Phase 2a single-centre, open single-arm study in patients with Amyotrophic Lateral Sclerosis (ALS) of intermediate progression rate. Eligible subjects will be administered weekly doses of ILB. A total of 5 subcutaneous (s.c.) doses will be administered at the study clinic.

The study consists of 10 visits; One 2-part screening visit, 5 ILB administration visits, and 3 follow-up visits. Each individual patient's study participation will be 4 months, including the screening and follow-up visits. Fifteen patients are planned to be included.

The primary objective of the study is to evaluate the safety and tolerability of ILB in patients diagnosed with ALS.

ILB is a solution for subcutaneous (s.c.) injection in saline solution. The dose administered will depend on the subject's body weight at the second study visit, prior to the first ILB administration.

No formal sample size calculation has been performed for this study. The proposed sample size is considered sufficient in this early phase 2 development to provide adequate information on the patients. Categorical data will be presented as counts and percentages. Continuous data will be summarised using descriptive statistics.

Secondary Outcome Measures

Name	Time	Method
Change in pulmonary function (FVC) from baseline	up to 3 months
Change in functional rating with Norris rating scale	up to 3 months	The Norris rating scale provides a physician-generated estimate of the patient's degree of functional impairment, which can be evaluated serially to objectively assess any response to treatment or progression of disease. The Norris rating scale includes questions that ask the physician to rate his/her impression of the patients level of functional impairment in performing one of 34 common tasks and bodily functions. Each task or function is rated on a four-point scale from 0 = can't do, to 3 = normal ability. Individual item scores are summed to produce a reported score of between 0=worst and 100=best; Absolute change from baseline at 3 months
Change in maximum plasma concentration (Cmax) of ILB	up to 1 month
Change in plasma concentration of hepatocyte growth factor (HGF)	up to 1 month

The ALSFRS-R includes questions that ask the physician to rate his/her impression of the patients level of functional impairment in performing one of twelve common tasks. Each task is rated on a five-point scale from 0 = can't do, to 4 = normal ability. Individual item scores are summed to produce a reported score of between 0=worst and 48=best; Absolute change from baseline at 3 months
Change in Quality of Life (QoL) assessed by visual analogue scale (VAS)	up to 1.5 months	Questionnaire with three questions for patient and next-of-kin self reporting of: * general health status; * physical health status; * mental health status; Each item is rated on a millimeter scale from 0 = very bad, to 100 = very good; Absolute change from baseline at 3 months
