Clinical Trial Summary

To evaluate whether time-to-improvement is significantly better in IMU-838 plus Oseltamivir (IONIC Intervention) and standard care vs. Oseltamivir and standard care in adult subjects with coronavirus disease (COVID-19)

Description:

The IONIC Protocol describes an overarching trial design to provide reliable evidence on the efficacy of IMU-838 (vidofludimus calcium) when delivered in combination with an antiviral therapy (Oseltamivir) [IONIC Intervention] for confirmed or suspected COVID-19 infection in adult patients receiving usual standard of care.

At present, there are no known treatments for COVID-19. Whilst, the anticipated scale of the epidemic is such that hospitals, and particularly intensive care facilities, may be massively overstretched. As described by a few models of pandemic spread, up to 50% of the adult population may fall sick over a period of 8-12 weeks, of whom around 10% may require hospitalisation. This figure could imply nearly 2 million hospital admissions. Considering this scenario, therapies which may only have a moderate impact on survival or on hospital resources could be worthwhile.

Critically, the present trial design has been developed with consideration of the front-line hospital staff working within an overstretched care system in these unprecedented times. To minimise their burden the protocol is deliberately flexible so that it is suitable for a wide range of settings, allowing:

• a broad range of patients to be enrolled (patient pathway, disease stage or mode of diagnosis)

• Additional sub-studies may be added to provide more detailed information on side effects or sub-categorisation of patient types but these are not the primary objective and are not required for participation.

• To be able to include more sites: the investigators will initiate the trial as a single centre (UHCW) and more sites invited to participate according to the emerging evidence

• The investigator have included 'Exploratory and Secondary objectives' in the protocol however, in consideration of the circumstances the research activities will emulate investigations performed as per standard care/routines care to minimise any burden on the delivery teams.

This is a Phase 2b, randomised, parallel-group, open-label study to assess the efficacy and safety of an oral dose of IMU-838 (22.5 mg twice daily [45 mg/day]) plus Oseltamivir (75mg twice daily [150mg/day]) (IONIC Intervetion) or Oseltamivir alone (75mg twice daily) in hospitalised patients with COVID-19.

Exclusion Criteria

Therapy Exclusion Criteria:

Use of the following concomitant medications is prohibited at Screening Visit and throughout the duration of the trial:

1. Use of Oseltamivir for more than 48 hrs prior to the first treatment dose

2. Use of antiviral drugs (e.g. nucleoside analogue reverse-transcriptase inhibitors, protease inhibitors, etc.)

3. History of long-term or concurrent use of mycophenolate mofetil, methotrexate exceeding 17.5 mg weekly

4. Chloroquine or hydroxychloroquine

5. Any medication known to significantly increase urinary elimination of uric acid, in particular lesinurad as well as uricosuric drugs such as probenecid

6. Treatments for any malignancy, in particular irinotecan, paclitaxel, tretinoin, bosutinib, sorafinib, enasidenib, erlotinib, regorafenib, pazopanib and nilotinib

7. Any drug significantly restricting water diuresis, in particular vasopressin and vasopressin analogues

8. Use of rosuvastatin at daily doses higher than 10 mg

Medical History of Concomitant Disease Exclusion Criteria

• Allergic or hypersensitivity to the IMU-838, Oseltamivir, or any of the ingredients

• Pregnant or breastfeeding or with intention to become pregnant during the study

• Participants who cannot take trial medication orally at presentation

• Undergoing active chemotherapy or radiotherapy.

• If the attending clinician believes that there is a specific contra-indication to the IONIC intervention.

• Patient has a medical or concomitant disease history preventing them from participating

• Critical patients whose expected survival time < 48-72 hours

• Evidence of pancytopenia or immunosuppression

• Any contraindication to Oseltamivir or standard of care

Presence of the following laboratory values at Screening Exclusion Criteria

• Platelet count <100,000/mm³ (<100 x 109/L)

• Total bilirubin > 2 x ULN or ALT or GGT > 5 x ULN

• Elevated indirect (unconjugated) bilirubin >1.2 x ULN (i.e. >1.1 mg/dL)

• Serum uric acid levels at Screening Visit >1.2 x ULN (for women >6.8 mg/dL, for men >8.4 mg/dL)

• Renal impairment defined as estimated glomerular filtration rate =45 mL/min/1.73m²

• Decompensated liver cirrhosis (Child-Pugh score B and C)

• History or presence of serious or acute heart disease such as uncontrolled cardiac dysrhythmia or arrhythmia, uncontrolled angina pectoris, cardiomyopathy, or uncontrolled congestive heart failure (New York Heart Association [NYHA] class 3 or 4)

• Cardiac disease resulting in marked limitation of physical activity. Patients are comfortable at rest. Less than ordinary activity causes fatigue, palpitation, dyspnea, or anginal pain. NYHA class 4: Cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of heart failure or the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.

• History or presence of any major medical or psychiatric illness (such as severe depression, psychosis, bipolar disorder), history of suicide attempt, or current suicidal ideation, if any of those conditions in the opinion of the investigator could create undue risk to the patient or could affect adherence with the trial protocol
