Summary

Show definitions

At present there is no approved drug treatment for Covid-19. In this study we plan to investigate if an experimental drug called IMU-838 (vidofludimus calcium) can improve your symptoms, prevent worsening that would initiate further treatments such as ventilation, and can lower your virus number if given in addition to your doctor's choice of standard therapy. We will also test if IMU-838 has any side effects and measure the level of IMU 838 in your blood.

Experimental drug means that it is not yet authorized for marketing in your country. To date approximately 600 individuals have received IMU-838 (or a drug similar to IMU-838 that contains the same active substance as IMU-838) in research studies.

Description

The trial consists of a Phase 2 proof-of-concept phase (Part 1) with the option to extend enrollment (without interruption) to Phase 3 (Expansion Phase, Part 2).

This trial is a multicenter, double-blind, placebo-controlled, randomized, parallel-group trial to evaluate the safety and efficacy of IMU-838 as addition to investigator's choice of SoC treatment in patients with COVID-19. Eligible patients will be centrally randomized 1:1 to twice-daily (BID) oral 22.5 mg IMU-838 (45 mg/day + SoC) or placebo (+ SoC). Randomization will be stratified by age (< or >=65 years) and antiviral therapy (no antivirals, Hydroxychloroquine and Chloroquine, all other antivirals).

Adaptive sequential trial design and overall trial design

The trial uses an adaptive sequential design. An IDMC will review unblinded data and provide the Sponsor with recommendations regarding modifications of sample size and trial conduct.

A 1st interim analysis (IA1) will be performed after approximately 200 patients have completed the trial (either as scheduled or prematurely), while enrollment continues. If no activity of IMU 838 is observed by the IDMC in this IA, further patient enrollment will be stopped, and a final analysis of Part 1 will be performed (FA1). It is expected that the final analysis of Part 1 will include approximately 230 patients. If the IA1 results indicate activity of IMU-838 in COVID-19, the trial may be extended to Part 2 with a revised sample size derived by the IDMC based on IA1 results and with possible other trial adjustments. If the trial is extended into Part 2, a 2nd IA (IA2) is planned after approximately two-thirds of patients (based on the overall global sample size [Part 1 and Part 2 combined]) have been enrolled to potentially adjust sample size and other trial features if needed. The final analysis of the trial (FA2) will then be done after all patients have completed Part 2.

In addition, an early interim safety analysis will be performed and evaluated by the IDMC after 30 patients have been enrolled to assess unblinded safety data. Further safety analyses can be initiated at any time by the IDMC or Sponsor when new safety signals are identified within this or other trials of IMU-838.

Screening

Patients can be screened for a maximum of 2 days (from Day -2 to Day 0) and eligible patients will be randomized on Day 0 and treated with IMP + SoC for 14 days. It is encouraged to screen potential participants immediately at the day of hospitalization (including informed consent, assessment of inclusion/exclusion criteria, screening laboratory tests all done locally, assessment of clinical and blood gas criteria) and randomize patients on the same day (Day 0). To assess eligibility criteria, existing local laboratory values obtained within 48 hours of randomization can also be used, except for testing of positive status of SARS-CoV-2 infection where a 4-day window is allowed.

IMP administration should start as quickly as possible after randomization and first IMP intended to be given in the evening of the screening day (Day 0).

Blinded Treatment period (Day 0 to Day 13) and Day 14 (end-of-treatment)

The first dose of IMP (2 tablets) should always be given on Day 0 (allowed range for first dose: 12:00 noon on Day 0 to 02:00 a.m.). All further IMP doses are 1 tablet each in the morning and evening. Information about the status and patient care are continuously obtained and documented once or twice daily.

After the last IMP dose in the evening of Day 13, the end-of-treatment assessments will be done on Day 14. Blood sampling for IMU-838 trough values must be performed in the morning around the time the morning dose was usually taken by the respective patient. Patients may then continue to receive SoC without any further restrictions on concomitant medications as during the 14-day BT period .

Day 28 Visit (EoS)

The patient should return for the final trial visit on Day 28 (EoS). If IMP is prematurely discontinued for any reason, the EoS visit should always be conducted on Day 28 and no earlier EoS should be performed. If patients withdraw from IMP prematurely, they should be encouraged to allow the EoS visit as part of the follow-up. If the patient dies during the trial, the investigator should indicate that this visit was not performed. However, even if no EoS visit was performed, information about patient status should be reported on the EoS page in the case report form. If the patient refuses any EoS visit or the patient is lost to follow-up, it is permissive in this trial that the investigator contacts the patient, the family of the patient or the referring physician by phone or email to obtain status of life information, or is able to search in registers or publicly available information for such status of life information.

Eligibility		Yes	No	Not Sure
Inclusion Criteria
	Male or female patients at least 18 years old (may be extended to include also children 12 years or older after the 1st interim analysis)
	Admitted to the hospital or other medical in-patient treatment facility for treatment of COVID-19 The hospitalization needs to be for medical reasons (treatment of COVID-19 disease) and cannot be for social reasons or due to housing insecurity
	For US sites only: If the investigator would commonly hospitalize the patient
	but for healthcare resource reasons decides to treat the patient in a
	specially designed out-patient setting, then such patients are also allowed to
	enter the trial (please note that in this case the patient would be counted as
	clinical status category 3). The investigator then must assure that the
	patient has at least a twice daily assessment by qualified trial personnel and
	all laboratory assessments can be adequately performed as per protocol. The
	Sponsor reserves the right to discontinue this option via administrative
	letter if such assurances cannot be met by any site
	\. SARS-CoV-2 infection confirmed by reverse transcriptase polymerase chain
	reaction (RT-PCR) test in a nasopharyngeal, oropharyngeal or respiratory
	sample at 4 days before randomization
	\. Moderate COVID-19 disease defined as fulfilling clinical status category 3
	or 4 on the WHO 9-point ordinal scale [21]
	Category 3: Hospitalized (see note above for US only), virus-positive, no oxygen therapy with the following conditions
	The hospitalization needs to be for medical reasons (treatment of COVID-19 disease) and cannot be for social reasons or due to housing insecurity
	Category 4: Hospitalized, virus-positive, oxygen by mask or nasal prongs (excluding high-flow oxygen therapy) with the following conditions
	Peripheral capillary oxyhemoglobin saturation (SpO2) >92% at maximum of 6 liters oxygen flow per minute

Presence of at least 1 symptom characteristic for COVID-19 disease i.e., fever, cough or respiratory distress 6\. Willingness and ability to comply with the protocol 7\. Written informed consent given prior to any trial-related procedure 8\. For women of childbearing potential: Application of a highly effective method of birth control (failure rate less than 1% per year when used consistently and correctly) together with a barrier method between trial consent and 30 days after the last intake of the IMP
	Highly effective forms of birth control are those with a failure rate less
	than 1% per year and include
	oral, intravaginal, or transdermal combined (estrogen and progestogen containing) hormonal contraceptives associated with inhibition of ovulation
	oral, injectable, or implantable progestogen-only hormonal contraceptives associated with inhibition of ovulation
	intrauterine device or intrauterine hormone-releasing system
	bilateral tubal occlusion
	vasectomized partner (i.e., the patient's male partner underwent effective surgical sterilization before the female patient entered the clinical trial and is the sole sexual partner of the female patient during the clinical trial)
	sexual abstinence (acceptable only if it is the patient's usual form of birth control/lifestyle choice; periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal are no acceptable methods of contraception)
	Barrier methods of contraception include
	Condom
	Occlusive cap (diaphragm or cervical/vault caps) with spermicidal gel/film/cream/suppository 9\. Male patients must agree not to father a child or to donate sperm starting at Screening, throughout the clinical trial and for 30 days after the last intake of the IMP. Male patients must also
	abstain from sexual intercourse with a female partner (acceptable only if it is the patient's usual form of birth control/lifestyle choice), or
	use adequate barrier contraception during treatment with the IMP and until at least 30 days after the last intake of the IMP, and
	if they have a female partner of childbearing potential, the partner should use a highly effective contraceptive method as outlined in inclusion criterion 8
	if they have a pregnant partner, they must use condoms while taking the IMP to avoid exposure of the fetus to the IMP
Exclusion Criteria
	Underlying disease-related exclusion criteria
	Involvement in the trial is not in the patient's best interest according to the investigator's decision, including the presence of any condition that would, in the assessment of the investigator, not allow the protocol to be followed safely Note: The investigator should particularly consider exclusion of patients at increased risk for serious or fatal AEs in case of worsening of the pulmonary perfusion. This includes, but is not limited to, pre-existing pulmonary hypertension, severe chronic respiratory disease, severely increased risk for thromboembolic complications and moderate to severe left ventricular ejection fraction (LVEF) dysfunction. In addition, other known risk factors of highest risk of mortality in COVID-19 patients should be considered
