This is an interventional treatment trial for Amyotrophic Lateral Sclerosis focused on measuring ALS, Antiretroviral Therapy, Triumeq Read More

Inclusion Criteria:

Subjects must meet all of the following inclusion criteria to be eligible to participate in this study:

• Age 18-75 years at the time of the screening visit
• Able to provide informed consent and comply with study procedures
• Sporadic ALS diagnosed as probable, laboratory-supported probable or definite according to the World Federation of Neurology El Escorial revised criteria as determined by a neurologist with neuromuscular sub-specialty training
• Diagnosis <24 months from date of enrolment
• (Forced) Vital capacity at least 60% of predicted value for gender, height and age at the screening visit
• Must be on a stable dose of riluzole for at least 30 days prior to the screening visit.
• Subject has established care with a neurologist at one of the four specialized ALS clinics involved in the study and will maintain this clinical care throughout the study.
• Subjects can participate in clinical registries, but will be excluded to this protocol if they are participating in a clinical trial involving additional or investigative treatment exposure.

Exclusion Criteria:

A participant will be excluded if he or she has any of the following:

• Dependence on mechanical ventilation at the time of screening
• Gastrostomy at the time of screening
• Absence of Upper Motor Neuron Signs
• Participation in any other investigational drug trial or using investigational drug (within 12 weeks prior to screening)
• Known hypersensitivity to dolutegravir, abacavir or lamivudine, or to any of the excipients
• Presence of the HLA-B*5701 allele at screening
• Presence of a monogenic cause of ALS (e.g. known mutation in SOD1, expansion in c9orf72 etc.)
• History of positive test or positive result at screening for HIV
• Subjects positive for Hepatitis B at screening (+HBsAg), or anticipated need for Hepatitis C virus (HCV) therapy during the study*;
• Women must not be able to become pregnant (post menopausal for >1 year, surgically sterile, adequate contraception) or breastfeed for the duration of the study. Women of childbearing potential must have a negative pregnancy test at screening and be non-lactating
• Other interventional clinical trial
• Subject is taking medication contraindicated with Triumeq. Dofetilide (or pilsicainide [available in Japan]) is prohibited as DTG may inhibit its renal tubular secretion resulting in increased dofetilide concentrations and potential for toxicity.
• Presence of any of the following clinical conditions at the time of screening:

Drug or alcohol abuse Unstable medical disease (such as unstable angina or chronic obstructive pulmonary disease), or active infectious disease (such as Hepatitis B or C or tuberculosis), or current malignancy Unstable psychiatric illness defined as psychosis or untreated major depression within 90 days of the screening visit. This exclusion criteria is based on a prior psychiatric diagnosis that is unstable as determined by the subject's treating Psychiatrist Dementia as previously diagnosed by a medical practitioner

• Safety Laboratory Criteria at the screening visit: Alanine aminotransferase (ALT) >5 times the upper limit of normal (ULN), OR ALT >3xULN Total bilirubin, lactate, triglycerides, amylase, or lipase greater than 2.0 times the upper limit of normal Subject has creatinine clearance of <50 mL/min via Cockroft-Gault method Subjects with moderate to severe hepatic impairment (Class B or greater) as determined by Child-Pugh classification; Absolute neutrophil count of < 1 x 109/L Platelet concentration of < 100 x 109/L Haemoglobin < 100g/L
