Clinical Trial Summary

This expanded access protocol is to provide access to the investigational product, SLS-005, to participants with ALS who are not eligible to participate in clinical trials.

Description:

Approximately 70 participants receive a weekly infusion of SLS-005 for up to 24 weeks. There are 25 infusions over 24 weeks (first infusion occurs at the Screening/Baseline Visit). In addition to infusion visits, participants will have three scheduled in-clinic visits at Screening/Baseline, Week 3, and Week 24, and 2 phone call or telemedicine visits at Week 12 and approximately 28 days following the last dose of the investigational medical product.

5. Capable of providing informed consent and complying with study procedures, in the Site Investigator's (SI's) opinion.

6. Participants have established care with a physician at the specialized ALS center involved in the study and will maintain this clinical care throughout the duration of the EAP.

7. Participants must have a life expectancy of at least 6 months in SI's opinion.

Exclusion Criteria:

1. Current diagnosis or healthcare professional-recommended treatment (medication, exercise or diet) of diabetes mellitus.

2. Screening glucose >=140 mg/dl.

3. Known hypersensitivity to trehalose.

4. Current use of oral trehalose.

5. Inability for participant to return to site for weekly drug administration, until approved for home infusions.

6. Screening body weight >144 kilograms.

7. Participant with a history of any clinically significant or unstable medical condition or lab abnormality based on the SI's judgment that may interfere with assessment of the study objectives, with safety or full participation.

8. Females who are pregnant or nursing or who plan to get pregnant during the course of the EAP.

9. Females of child-bearing potential, or males, who are unwilling or unable to use highly effective methods of birth control.

10. Use of investigational treatments for ALS (as part of participation in a clinical trial or another EAP) within 5 half-lives (if known) or 30 days (whichever is longer) prior to the Screening Visit.

11. Permanent assisted ventilation (PAV), defined as more than 22 hours per day of noninvasive or invasive mechanical ventilation for more than seven consecutive days. The date of onset of PAV is the first day of the seven days.

12. Active cancer or history of cancer, except for the following: basal cell carcinoma or successfully treated squamous cell carcinoma of the skin, cervical carcinoma in situ, prostatic carcinoma in situ, or other malignancies curatively treated and with no evidence of disease recurrence for at least 3 years.
