Plain English Summary

Background and study aims
Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease. Unfortunately, there are limited medications available for ALS. The only available treatment is riluzole, which tends to provide only minimal benefit. Therefore, there is a high need for further research using other medications, to help improve the options for treatment for this disease.
There has been laboratory research that suggests that a virus called an endogenous retrovirus may be the cause or trigger for ALS in some people. This virus may be of the same family (although quite different) to the virus that causes HIV (also called ‘AIDS’). Researchers are intending to test if an anti-viral medication that is a very effective treatment for HIV, may also be effective for people who have ALS.
Triumeq, commonly prescribed for HIV treatment, is an antiviral medication that is a combination of three medications: dolutegravir 50 mg, abacavir 600 mg, and lamivudine 300 mg. Triumeq is approved by the Therapeutic Goods Administration (TGA) to treat HIV patients. However, it is not approved to treat ALS. Therefore, it is an experimental treatment for ALS.
The aim of this study is to determine whether Triumeq is effective at delaying the progression of ALS, and whether it is safe and well-tolerated in patients with ALS. The Lighthouse study demonstrated Triumeq to be safe and well tolerated in people with ALS.

Who can participate?
Patients aged 18 years and over with ALS

What does the study involve?
The entire study will last for around 2 years. Participation is voluntary. Participation in this study will involve up to 10 visits (about 2 hours each) roughly every 3 months, and as many telephone calls as participants would like, to make sure they are comfortable with the research process. Participants will be assessed throughout the project using assessment scales to determine if it is suitable for them to continue the medication.
Participants will be randomly allocated to receive either Triumeq or a matching placebo (dummy drug) once daily in addition to standard care. The random allocation will be done using a computer maintained by the King’s Clinical Trials Unit. Two thirds of research participants will receive active Triumeq and one third will receive matched placebo capsules. A placebo is a medication with no active ingredients and so has no medical benefit. It looks like the real thing, but it is not. The study is a ‘double-blind’ study. This means that neither participants nor the study doctor will know which treatment they are receiving. However, in certain circumstances the study doctor can find out which treatment participants are receiving. This study has been designed to make sure the researchers interpret the results fairly without any bias and avoids study doctors or participants jumping to conclusions.
There are a number of procedures and reviews that will be carried out at different times over the 24 months:
1. Demographics
2. Review of medical history
3. Physical examination/vital signs
4. Neurological exam
5. Blood collection
6. Urine collection
7. Throat or nasal swab: the doctor/nurse/research coordinator will perform either a throat or nasal swab to check for COVID-19 infection
8. Spirometry (breathing) test
9. Questionnaire completion
10. ECG test

What are the possible benefits and risks of participating?
The researchers cannot guarantee or promise that participants will receive any benefits from this research; however, possible benefits may include some relief of ALS symptoms. The tests provided may help participants learn about their general health. This study may assist doctors and scientists to help people suffering from symptoms with ALS in the future.
Medical treatments often cause side effects. Participants may have none, some or all of the effects listed below, and they may be mild, moderate or severe. There may be side effects that the researchers do not expect or do not know about and that may be serious. Many side effects go away shortly after treatment ends. However, sometimes side effects can be serious, long-lasting or permanent. If a severe side effect or reaction occurs, the study doctor may need to stop the treatment.
The following side effects have been experienced by people taking Triumeq:
Common side effects (occur in 1 out of 10 people): fever, not feeling well, discouragement, nausea, rash, irritability, loss of interest and/or pleasure, trouble concentrating and/or sleeping.
Uncommon side effects (occur in 1 out of 100 people): neuropathy (tingling in fingers and toes), anxiety, difficulty moving, weight loss, itching and hair loss as well as high blood sugar.
Rare side effects (occur in 1 out of 10, 0000 people): abnormal liver function tests, low blood pressure dizziness or light-headedness, fainting or lack of concentration or fatigue, acute inflammation of the pancreas, nausea, fever and a swollen and or tender abdomen and hepatitis, joint pain, abdominal pain and yellowing of the skin.

Scientific titleRandomized double-blind placebo-controlled Phase III trial of Triumeq in amyotrophic lateral sclerosis
Study acronymLighthouse II
Study hypothesisActivation of a human endogenous retrovirus is a key component of the pathogenesis of amyotrophic lateral sclerosis (ALS), and blocking its lifecycle with antiretroviral therapy will therefore provide an effective treatment.

InterventionLighthouse II is an international, phase III, multi-centre, parallel-group, placebo-controlled, blinded (participant, investigators, analyst) randomised controlled trial of Triumeq (abacavir 600 mg, lamivudine 300 mg and dolutegravir 50 mg) or matched placebo, once daily in addition to standard care, in a 2:1 treatment/placebo allocation ratio in participants with ALS, in order to determine the superiority of treatment versus placebo. If the trial is not terminated at a planned interim analysis, the trial will continue until 24 months after the last enrolled participant or a minimum of 212 events have occurred, whichever is first.
