Assessing Motor Neuron Disease Mechanisms by Threshold Tracking Transcranial Magnetic Stimulation and Magnetic Resonance Spectroscopy

Amyotrophic Lateral Sclerosis (ALS) is a motor neuron disease, which cases the death of neurons controlling the voluntary muscles. The death of motor neurons leads eventually to muscle weakness and muscle atrophy and as a consequence thereof, ALS patients die in average within three years after symptom onset due to respiratory failure. No cure for ALS is currently known, and the medical diagnosis and clinical treatment are impeded by the lack of reliable diagnostic tools for objective disease assessment, and by the limited insight in disease pathophysiology since the underlying disease mechanisms still have not been fully elucidated. An unbalance in the concentrations of GABA and glutamate, the most important inhibitory and excitatory brain metabolites, is suggested to play a role in the disease mechanisms of ALS. By applying Magnetic Resonance Spectroscopy (MRS), a magnetic resonance method which allows for quantification of brain metabolites, GABA and glutamate concentration can be quantified and thus hopefully elucidate their role in ALS disease mechanism. Threshold Tracking Transcranial Magnetic Stimulation (TT-TMS) studies carried out by a single research group have demonstrated cortical hyperexcitability (a physiology state in which neurons in the cerebral cortex are easier activated) as an early feature in ALS patients. For this reason, TT-TMS was suggested as a biomarker of ALS by the research group. However, to be able to suggest a test as a biomarker, one must show the test is reliable and reproducible. The objectives of this study are therefore: to explore the pathophysiology of ALS by investigating the interaction between neuronal networks as assessed by TT-TMS and conventional TMS and MRS, and to investigate the reliability and reproducibility of TT-TMS. The aim is to examine the utility of TT-TMS and MRS as diagnostic tools for objective detection of ALS in the early disease stage. The study will include 60 participants in total, subdivided into two groups: 30 healthy participants and 30 patients with clinical suspicion of motor neuron disease or ALS. Each participant will undergo examination with TMS and MRS, the primary outcomes will be compared between the two groups and the results from the TMS examinations and the MRS-scans will be correlated.

To Determine the Maximum Tolerated Dose (MTD) of HK-001 in Healthy Volunteers

Eligible subjects will receive either different dosages of HK-001 or placebo in a 3:1 ratio in 1 of the 7 dose cohorts. After single dose administration, followed by an independent Data and Safety Monitoring Board (DSMB) meeting for safety assessments (including the available plasma pharmacokinetic profile), the subjects will be allowed to receive (Z)-BP or placebo twice a day orally at the study site for 14 consecutive days and follow up on the 28th day after the last dose administration by a site visit. The study drugs (including placebo) will be administered at the study site by following the investigator's instructions to either perform blood sampling for pharmacokinetic evaluation or maximize the treatment compliance. There will be 7 cohorts and subjects will be randomized into cohorts consisting of 8 subjects each (6 active and 2 placebo controls per cohort). Dose cohorts will be escalated sequentially from low to high dose (50 mg, BID; 100 mg, BID; 150 mg, BID; 225 mg, BID; 300 mg, BID; 400 mg, BID; 525 mg, BID) by following a modified Fibonacci sequence, and based on the decision of an independent DSMB at a set time point. Following all subjects of a cohort complete the safety and PK evaluation after receiving the last dose administration, a cohort at the next dose level will be launched if the DSMB does not identify significant safety concerns after reviewing safety data and PK profiles.

Virtual Peer-to-peer Support Programme for Carers of MND

Background/scope There is growing recognition that family caregiving is a serious public health issue requiring supportive interventions. Family caregivers play an essential role in sustaining a stable environment enabling individuals with motor neurone disease (MND) that are technology dependent to live at home. The family caregivers can experi¬ence exceptional burden and significant decline in psychological wellbeing due to MND's rapid and pro¬gressive nature with profoundly debilitating effects and intensive support needs. Dependence on assistive technology adds an additional level of complexity to family caregiving due to the need to learn how to operate and troubleshoot medical devices, train other caregivers, and negotiate appointments with new specialties within the healthcare system. Despite the recognized impact of caregiving for individuals with MND, data are scarce as to effective interventions that provide direct practical and psychosocial supports. Difficulty accessing support may increase psychological distress. As the burden of caring increases due to disease progression and increasing technology dependence, access to existing informal support networks may diminish. Online peer support using virtual modalities is a flexible and low cost form of support. Peers, people who have experienced the same health problem and have similar characteristics as support recipients, can be a key source of emotional, informational, and affirmational support. Peer support improves psychological well-being of caregivers of people with conditions such as dementia, cancer, and brain injury. Although peer support programmes for family caregivers of people with MND exist, data as to their efficacy are limited. Therefore, we have developed an online peer support programme, completed beta and usability testing and now propose to test the effect on caregiver psychological wellbeing and caregiver burden. Aim/research question(s) Overall aim: to determine the efficacy of a 12-week online peer support programme on family caregiver psychological health and caregiver burden. Primary research question: What is the effect of the online peer support programme on psychological distress measured using the Hospital Anxiety and Depression Scale (HADS)? Secondary research questions: What is the effect on positive affect, caregiver burden, caregiving mastery, caregiving personal gain, and coping? How do participants use the programme (fidelity and reach)? What is the perceived usability and acceptability? Methods The investigators will conduct a parallel group randomised controlled trial with participants allocated to 12-week access to the online peer support programme or a usual care control group. The investigators will enrol family caregivers of an individual with MND who is referred for consideration or receiving any of the following assisted ventilation cough assist gastroscopy and enteral feeding i.e., entering King's clinical staging Stage 4A: nutritional support; or Stage 4B: respiratory support [51]: The 12-week peer-to-peer support programme entails: audio, video, or text private messaging; synchronous weekly chat; asynchronous discussion forum; and informational resources. The investigators will collect demographic and caregiving data including the Caregiver Assistance Scale and Caregiving Impact Scale, and caregiver measures (HADS, Positive and Negative Affect Schedule, Zarit Burden Interview, Pearlin Mastery Scale, Personal Gain Scale, Brief COPE) at baseline and programme completion. The investigators will download use of online peer support programme features, assess usability, and conduct semi-structured interviews to explore acceptability using the Theoretical Framework of Acceptability. To test for a medium size effect (d=0.5), at 5% level of significance (2-sided) with power 80%, 64 participants are required in each arm (128 total). Adjusting for 20% attrition requires 154 participants. Proposed findings The proposed study will demonstrate the effect of a online peer support programme on psychological distress, positive affect, caregiving burden, mastery, personal gain and coping. Data on programme fidelity will enable the investigators to objectively assess acceptability and interpret study results. Data on usability and acceptability will inform future scalability of the online peer support programme outside of the trial both nationally and internationally, and to other family caregiver populations.

HERV-K Suppression Using Antiretroviral Therapy in Volunteers With Amyotrophic Lateral Sclerosis (ALS)

Background: - Some people with Amyotrophic Lateral Sclerosis (ALS) have a high level of the virus HERV-K in their blood. Researchers do not think this virus causes ALS. But they don t know why some people with ALS have a high level of it. They want to know if HERV-K can be suppressed by drugs that are used to treat HIV infection. Objectives: - To learn how drugs usually taken for HIV infection affect people with Amyotrophic Lateral Sclerosis (ALS). Eligibility: - Adults at least 18 years old with ALS and high levels of HERV-K but no HIV. Design: Interested participants can contact the study team and, if eligible, the study team will arrange for a screening blood draw to determine the HERV-K level. Participants with a high HERV-K level will be screened with medical history, physical exam, questionnaires, nerve conduction test, lumbar puncture, and blood and breathing tests. After screening, participants will start taking the 4 study drugs. Participants will have up to 12 study visits over a period of 72 weeks. After starting study drugs, they will have study visits at Weeks 1 and 4 and then every 4 weeks until Week 28. They will be asked how they are feeling and have an exam and blood drawn. At 3 visits, they will have tests of nerve conduction, breathing, and their ALS symptoms. At Week 24, they will stop taking the study drugs and have a repeat lumbar puncture. After the Week 48 visit, their participation is finished.
