Clinical Trial Summary

The therapeutic hypothesis for the use of losmapimod in COVID-19 disease is that increased mortality and severe disease is caused by p38 mitogen-activated protein kinase (MAPK)-mediated exaggerated acute inflammatory response resulting from SARS-CoV-2 infection.

The study Sponsor hypothesizes that the early initiation of p38α/β inhibitor therapy in patients hospitalized with moderate COVID-19 who are at increased risk of a poor prognosis based on older age and elevated systemic inflammation will reduce clinical deterioration including progression to respiratory failure and death.

To address this hypothesis, Fulcrum Therapeutics is conducting a Phase 3, multicenter, randomized, double-blind, placebo-controlled study that will evaluate the safety and efficacy of losmapimod versus placebo in subjects 40 and older who are hospitalized with moderate COVID-19 disease.

Description:

The therapeutic hypothesis for the use of losmapimod in COVID-19 disease is that increased disease severity and consequent increased mortality is caused by p38 mitogen-activated protein kinase (MAPK)-mediated exaggerated acute inflammatory response resulting from SARS-CoV-2 infection.

It is anticipated that the early initiation of p38α/β inhibitor therapy in patients with moderate COVID-19 will prevent further clinical deterioration and reduce the need for both increased respiratory support as well as mortality. This is the main hypothesis for this study.

To address this hypothesis, Fulcrum Therapeutics is conducting a Phase 3, multicenter, randomized, double-blind, placebo-controlled study that will evaluate the safety and efficacy of losmapimod versus placebo in subjects with COVID-19 disease.

Losmapimod is currently in Phase 2 clinical trials for the treatment of facioscapulohumeral dystrophy (FSHD) and has previously been administered to more than 3600 adult healthy volunteers and subjects including participants in a large Phase 3 trial which evaluated clinical outcomes and safety after major cardiovascular events.

Patients will participate in this study for approximately 34 days. The total treatment duration will be 14 days. Subjects will be evaluated during a 3 day pre-treatment period (Screening and Baseline Visits) to establish pre-treatment baseline assessments and eligibility. Subjects will then be randomized to treatment with losmapimod or placebo for 14 days and assessed frequently for changes from pre-treatment in various clinical outcome assessments. Patients must have a confirmed diagnosis of COVID-19 by viral PCR prior to randomization and first dosing. Patients will receive 15 mg of losmapimod, or placebo twice daily given as two 7.5 mg tablets per dose by mouth: for a total of 4 pills or 30 mg daily for 14 consecutive days. All study visits during the first week of treatment are anticipated to be conducted in the inpatient setting while later visits are anticipated to be conducted as outpatient.

The primary endpoint of the study is to assess the efficacy of losmapimod tablets compared with placebo for the treatment of COVID-19 when administered concurrently with the local standard of care. Secondary endpoints include evaluating the effect of losmapimod compared with placebo on clinical outcomes, clinical status, effect on survival, safety, and tolerability and to characterize changes in the levels of SARS-CoV-2 infection.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Who Progressed to Death or Respiratory Failure by Day 28	Respiratory failure was defined as either need for mechanical ventilation (invasive or non-invasive) or high flow oxygen (defined by greater than 15 liters per minute [LPM] flow of oxygen to maintain oxygen saturation between 90% and 95%), sustained for at least 48 hours, at any time during the study. The fitted logistic regression model was used to predict the response rate for every participant in the study who had received the treatment or the control intervention. The efficacy of Losmapimod was assessed by the development of progression to critical disease as evidence of mortality or development of respiratory failure by Day 28. Percentage of participants who progressed to death or respiratory failure by Day 28 has been presented.	Up to Day 28
Secondary	Change From Baseline in Clinical Status at Days 7 and 14 Assessed on the 9-point World Health Organization (WHO) Ordinal Scale	Change in clinical status between Baseline and at Days 7 and 14 was modeled using ordinal logistic regression models, adjusting for stratification factors, sex and baseline C-reactive protein (CRP). WHO 9-point ordinal scale included score ranges as: 0:No clinical evidence of the disease, 1: Discharged from the hospital and without any limitation, 2: Discharged from the hospital but with limitation of activities, 3: Hospitalized but not requiring oxygen therapy, 4: Oxygen therapy but not requiring high-flow or non-invasive ventilation, 5: Noninvasive ventilation or high-flow oxygen therapy, 6: Intubation and mechanical ventilation, 7: Ventilation plus additional organ support and 8: Death. Higher scores indicated worse clinical status. Baseline was defined as the last measurement prior to the first dose of study drug. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.	Baseline and at Day 7 and Day 14
Secondary	Total Number of Study Days Free of Oxygen Supplementation	A Poisson regression model or a negative binomial model was used to assess the relationship with treatment, adjusting for stratification factors, sex, baseline CRP and number of days on study (as applicable). Total number of study days free of oxygen supplementation has been presented.	Up to Day 28
Secondary	Percentage of Participants Reporting All-cause Mortality at Day 28	Percentage of participants who reported death have been presented.	At Day 28
Secondary	Number of Study Days Alive	A Poisson regression model or a negative binomial model was used to assess the relationship with treatment, adjusting for stratification factors, sex, baseline CRP and number of days on study (as applicable). Number of study days alive has been presented.	Up to Day 28
Secondary	Number of Participants Reporting Non-serious Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment. Number of participants with non-serious AEs and SAEs has been presented.	Up to Day 28
