Study Description

Brief Summary:

The goal of this randomised, double-blind, placebo-controlled Phase II clinical trial is to assess the safety and effect of of IHL-675A in rheumatoid arthritis patients on pain, and function according to RAPID-3.

128 volunteers will be enrolled and randomised to one of four treatments (32 subjects per treatment). Each treatment will be self-administered twice daily for 24 weeks.

The four treatments are:

• Treatment 1 - IHL-675A
• Treatment 2 - CBD
• Treatment 3 - HCQ
• Treatment 4 - Placebo

Condition or disease	Intervention/treatment	Phase
Rheumatoid Arthritis	Drug: IHL-675A; Drug: Cannabidiol; Drug: Hydroxychloroquine; Drug: Placebo	Phase 2

Detailed Description:

This is a Phase II, double-blind, randomised, placebo-controlled clinical trial to assess the safety and effect of IHL-675A (a combination of cannabidiol (CBD) and hydroxychloroquine (HCQ)) on pain and function using the RAPID-3 patient reported outcome (PRO) in patients with Rheumatoid Arthritis. This study will compare IHL-675A to the component drugs, CBD and HCQ, as well as a placebo. The study will aim to enrol a total of 128 subjects across the 4 treatment groups (32 per group).

The study will also assess structural changes in joint damage in an MRI sub-study using the Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS).

During the 28-day screening period, subjects will provide information on their demographics, medical history, history of inflammatory conditions and weight/body mass index (BMI). A physical exam, vital signs, and 12-lead ECG will be conducted. Urine and blood samples will be collected for urinalysis, to assess for pregnancy, the presence of illicit drugs and to detect any clinically significant outcomes that would exclude subjects from being eligible for the clinical trial and to measure erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels. A series of questionnaires will be conducted to assess eligibility and mental health status.

These questionnaires will be:

• RAPID-3
• JC 66/68
• Health Assessment Questionnaire-Disability Index (HAQ-DI)
• Columbia-Suicide Severity Rating Scale (C-SSRS) Subjects will also undergo an optical coherence tomography (OCT) eye examination to rule out retinopathy.

Subjects who have consented to the MRI sub-study will also undergo an MRI during screening.

Once the participant is deemed eligible to be enrolled in the study, the baseline visit will be performed and the participant will be randomised into one of the four treatment groups:

• Treatment 1 - IHL-675A (150 mg CBD, 200 mg HCQ: two soft gel capsules each containing 75 mg CBD and 100 mg HCQ twice per day for a total daily dose of 300 mg CBD and 400 mg HCQ)
• Treatment 2 - CBD (150 mg: two capsules each containing 75 mg CBD twice per day for a total daily dose of 300 mg CBD)
• Treatment 3 - HCQ (200 mg: two capsules each containing 100 mg HCQ twice per day for a total daily dose of 400 mg HCQ)
• Treatment 4 - Placebo (two capsules twice per day).

Subjects will visit the clinic on Day 1 and undergo baseline assessments, including:

• RAPID-3
• JC 66/68
• ACR20
• CDAI-RA
• FACIT-F
• HAQ-DI
• AE
• Concomitant medication review
• Weight/BMI
• Physical exam
• Vitals
• ECG
• Safety blood collection

Subjects will then be supplied with their first 28-day supply of their allocated treatment and will be set up with and instructed on the use of an electronic patient reported outcome (ePRO) either web based or using an app on the subject's personal device. The ePRO will be used daily by the subject to record pain, joint stiffness, tiredness, and use of other pain medication for the control of pain associated with arthritis.

Every 4 weeks, subjects will return to the clinical to undergo the same assessments and to receive the next 28-day supply of their allocated treatment. At 24 weeks, subjects will take their final dose prior to their return to the clinical for the final time (and will not receive another supply of the treatment) where they will undergo the same assessments as well as a final OCT eye exam, and subjects in the MRI sub-study will undergo a final MRI.

Outcome Measures

Primary Outcome Measures :

1. Change in pain and function [ Time Frame: 24 weeks ]

   Routine Assessment of Patient Index Data 3 (RAPID-3) questionnaire to assess pain and function in arthritis patients.

   RAPID-3 is a pooled index of the 3 patient-reported American College of Rheumatology RA Core Data Set measures: function, pain, and patient global estimate of status. Each of the 3 individual measures is scored 0 to 10, for a total of 30. Disease severity may be classified on the basis of RAPID3 scores: >12 = high; 6.1-12 = moderate; 3.1-6 = low; < or =3 = remission

Secondary Outcome Measures :

1. Safety and tolerability - Incidence of the use of concomitant medications for pain management [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Incidence of the use of concomitant pain medications for the treatment of arthritis related pain. Subjects will report the use of rescue pain medication for pain associated with arthritis using an electronic patient reported outcome (ePRO) on their personal device.
2. Safety and tolerability - Vital signs - Temperature [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Change from baseline in body temperature (°C)
3. Safety and tolerability - Vital signs - Pulse Rate [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Change from baseline in pulse rate (BPM)
4. Safety and tolerability - Vital signs - Respiratory Rate [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Change from baseline in respiratory rate (RPM)
5. Safety and tolerability - Vital signs - Blood Pressure [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Change from baseline in systolic blood pressure (mmHg) and diastolic blood pressure (mmHg) to report change in blood pressure
6. Safety and tolerability - 12-lead ECG [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Change from baseline in 12-lead ECG results: PR interval, QRS, QTcF
7. Safety and tolerability - Adverse Events [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
   Assess the number of treatment emergent adverse events (TEAEs) and serious treatment emergent adverse events associated with the dosing of IHL-675A in comparison to the active comparators (CBD and HCQ), and placebo.
8. Safety and tolerability - OCT Eye Exam [ Time Frame: 24 weeks ]
   Changes from baseline in retinopathy as assessed by Optical Coherence Tomography (OCT) eye exam
9. Safety and tolerability - The Columbia Suicide Severity Rating Scale (C-SSRS) [ Time Frame: 24 weeks ]
   Change from baseline in suicidality assessed by The Columbia Suicide Severity Rating Scale (C-SSRS). The C-SSRS is an instrument that measures suicidal ideation and behaviour. The ideation subscale evaluates severity on a 5-point scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The behaviour subscale assesses various categories of suicidal behaviour. Higher scores on the C-SSRS represent more severe levels of suicidal ideation or behaviour. Lower scores, therefore, indicate a better outcome as it represents lower levels of suicidal ideation or behaviour.
10. Change in pain - Routine Assessment of Patient Index Data 3 (RAPID-3) [ Time Frame: 4, 8, 12, 16 and 20 weeks ]
    Change in pain from baseline. Assessed by change in Routine Assessment of Patient Index Data 3 (RAPID-3) score relative to baseline. RAPID-3 is a composite score that measures physical function, pain, and patient global assessment on a scale from 0 to 30, with higher scores indicating worse outcomes (i.e., more pain and disability). A decrease in the RAPID-3 score from baseline represents an improvement.
11. Change in fatigue - Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in fatigue from baseline. Assessed by change in the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) score. FACIT-F is a 40-item measure that assesses self-reported fatigue and its impact upon daily activities and function on a scale from 0 to 160. Higher scores indicate better outcomes (i.e., less fatigue). An increase in the FACIT-F score from baseline represents an improvement.
12. Change in quality of life - Health Assessment Questionnaire - Disability Index (HAQ-DI) [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in quality of life from baseline. Assessed by change in Health Assessment Questionnaire - Disability Index (HAQ-DI) score. The HAQ-DI assesses a patient's level of functional ability on a scale from 0 to 3. Higher scores indicate worse outcomes (i.e., greater disability). A decrease in the HAQ-DI score from baseline represents an improvement.
13. Change in disease activity - ACR20 [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in disease activity from baseline. Assessed by change in American College of Rheumatology-20 (ACR20) response rate. The ACR response is scored as a percentage improvement, comparing disease activity at two discrete time points (usually baseline and post-baseline comparison). ACR20 is ≥ 20% improvement
14. Change in disease activity - JC66/68 [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in disease activity from baseline. Assessed by change in joint swelling/tenderness count 66/68 (JC66/68). The 66/68 Joint Count evaluates 66 joints for swelling and 68 joints for tenderness and pain with movement. Note that the hip joints can be evaluated for tenderness only-not for swelling. The total score is composed of points that are based on the presence of pain and/or swelling in a joint
15. Change in disease activity - CDAI-RA [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in disease activity from baseline. Assessed by change in clinical disease activity index for rheumatoid arthritis (CDAI-RA) score. CDAI is based on the simple summation of the count of swollen/tender joint count of 28 joints along with patient and physician global assessment on VAS (0-10 cm) Scale for estimating disease activity. The CDAI has range from 0 to 76.
16. Change in inflammatory serology - C-Reactive Protein (CRP) [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in CRP levels from baseline. Assessed by the change in blood C-reactive protein (CRP) levels relative to baseline. CRP is a systemic marker of inflammation. The measurement is reported in milligrams per litre (mg/L). Higher levels of CRP typically indicate a higher level of systemic inflammation, so a decrease in CRP levels from baseline would generally indicate an improvement.
17. Change in inflammatory serology - Erythrocyte sedimentation rate (ESR) [ Time Frame: 4, 8, 12, 16, 20 and 24 weeks ]
    Change in ESR levels from baseline. This outcome is assessed by the change in blood erythrocyte sedimentation rate (ESR) levels relative to baseline. ESR is a systemic marker of inflammation. The measurement is reported in millimetres per hour (mm/hr). Higher ESR levels typically indicate a higher level of systemic inflammation, so a decrease in ESR levels from baseline would generally indicate an improvement.
18. Change in tiredness [ Time Frame: 24 weeks ]
    Change in tiredness from baseline. Assessed by an electronic patient reported outcome (ePRO). Subjects will be prompted daily to answer a set of 5 questions that will ask the patient about their pain, joint stiffness duration and severity, and tiredness, and to record the use of any concomitant medication for pain associated with arthritis.
19. Change in pain (daily) [ Time Frame: 24 weeks ]
    Change in pain from baseline. Assessed by an electronic patient reported outcome (ePRO). Subjects will be prompted daily to answer a set of 5 questions that will ask the patient about their pain, joint stiffness duration and severity, and tiredness, and to record the use of any concomitant medication for pain associated with arthritis.
20. Change in joint stiffness duration [ Time Frame: 24 weeks ]
    Change in joint stiffness duration from baseline. Assessed by an electronic patient reported outcome (ePRO). Subjects will be prompted daily to answer a set of 5 questions that will ask the patient about their pain, joint stiffness duration and severity, and tiredness, and to record the use of any concomitant medication for pain associated with arthritis.
21. Change in joint stiffness severity [ Time Frame: 24 weeks ]
    Change in joint stiffness severity from baseline. Assessed by an electronic patient reported outcome (ePRO). Subjects will be prompted daily to answer a set of 5 questions that will ask the patient about their pain, joint stiffness duration and severity, and tiredness, and to record the use of any concomitant medication for pain associated with arthritis.
22. Effect of IHL-675A on cytokines [ Time Frame: 12 and 24 weeks ]
    Change in cytokines IL-1β, IL-6, TNF levels compared to pre-dose levels.

Other Outcome Measures:

1. Structural effects of IHL-675A [ Time Frame: 24 weeks ]
   Change in Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) at 24 weeks (visit week 25) compared to baseline in a sub-study of subjects who have affected wrist and metacarpophalangeal joints (applicable to sub-study only).
