Incyte Announces Initiation of Phase 3 RUXCOVID Study Evaluating Ruxolitinib (Jakafi®) as a Treatment for Patients with COVID-19 Associated Cytokine Storm

Expanded Access Program allowing additional eligible patients with COVID-19 associated cytokine storm to receive ruxolitinib is also open for enrollment in the United States

WILMINGTON, Del.--(BUSINESS WIRE)-- Incyte (Nasdaq:INCY) today announced the initiation of RUXCOVID, a global, randomized, double-blind, placebo-controlled Phase 3 clinical trial evaluating the efficacy and safety of ruxolitinib (Jakafi^®) plus standard-of-care (SoC) in patients aged ≥12 years with COVID-19 associated cytokine storm. The collaborative study is sponsored by Incyte in the United States and Novartis outside of the United States.

The composite primary endpoint is the proportion of patients who die, develop respiratory failure (require mechanical ventilation) or require intensive care unit (ICU) care by Day 29. Secondary endpoints comprise various efficacy assessments including evaluation of clinical status using a 9-point ordinal scale; in-hospital outcomes (mortality rate; proportion of patients requiring mechanical ventilation; duration of hospitalization, ICU stay, supplemental oxygen, invasive mechanical ventilation); change in the National Early Warning Score (NEWS2); change in SpO₂/FiO₂ ratio; proportion of patients with no oxygen therapy (oxygen saturation of ≥94% on room air); and safety. RUXCOVID will enroll approximately 400 patients globally.

Additionally, given the urgent nature of the COVID-19 pandemic, Incyte is also initiating a separate emergency Expanded Access Program (EAP) in the United States. The protocol will allow eligible patients with severe COVID-19 associated cytokine storm to receive ruxolitinib while it is being investigated for this indication.

“There is an unprecedented unmet medical need for treatments that prevent or reduce severe COVID-19 related complications to improve outcomes for patients and alleviate the overwhelming pressure on the global healthcare system,” said Steven Stein, M.D., Chief Medical Officer, Incyte. “We thank the FDA for the expedited review of the RUXCOVID study and hope to enroll this important clinical trial as quickly as possible to determine the potential utility of ruxolitinib for treatment of patients with severe COVID-19 associated cytokine storm.”

RUXCOVID is the first Phase 3, randomized, placebo-controlled study designed to evaluate the efficacy and safety of ruxolitinib in patients with COVID-19 associated cytokine storm.

At present, there is ample commercial and clinical supply of ruxolitinib in the United States to meet the needs of U.S. patients receiving ruxolitinib in its approved indications and those participating in clinical trials. Incyte is increasing manufacturing efforts to respond to anticipated supply needs related to COVID-19 studies and working closely with distribution partners to monitor the supply of ruxolitinib.

About COVID-19 Associated Cytokine Storm
Cytokine storm is a severe immune overreaction that can be triggered by a viral infection and can lead to serious complications, including pneumonia and acute respiratory distress syndrome (ARDS). Patients with COVID-19 associated cytokine storm who experience these complications often require intensive care, including intubation and the use of mechanical ventilation, and are at an increased risk of mortality.

Emerging evidence suggests that regulating overactive signaling through the JAK-STAT pathway during a cytokine storm associated with COVID-19 could be a potential treatment approach, and it is hypothesized that ruxolitinib, a JAK1/JAK2 inhibitor, may be able to play a role in treating these patients.

Currently, there is limited clinical evidence on the safety and efficacy of ruxolitinib for the treatment of COVID-19 associated cytokine storm, and ruxolitinib is not FDA-approved for this use.

About RUXCOVID
RUXCOVID is a global, randomized, double-blind, placebo-controlled, 29-day, multi-center Phase 3 study evaluating the efficacy and safety of ruxolitinib plus standard of care (SoC) therapy in patients aged ≥12 years with COVID-19 associated cytokine storm compared to placebo plus SoC therapy.

The composite primary endpoint is the proportion of patients who die, develop respiratory failure (require mechanical ventilation), or require intensive care unit (ICU) care by Day 29. Secondary endpoints are comprised of various efficacy assessments including evaluation of clinical status using a 9-point ordinal scale; in-hospital outcomes (mortality rate; proportion of patients requiring mechanical ventilation; duration of hospitalization, ICU stay, supplemental oxygen, invasive mechanical ventilation); change in the National Early Warning Score (NEWS2); change in SpO₂/FiO₂ ratio; proportion of patients with no oxygen therapy (oxygen saturation of ≥94% on room air); and safety.

Eligible patients will be randomized 2:1 to receive oral ruxolitinib 5mg twice daily (BID) or oral-matching placebo for a total of 14 days. Study treatment will be given in combination with SoC therapy according to the investigator’s clinical judgement. After 14 days of therapy, should clinical signs or symptoms not improve or worsen, and the potential benefit outweighs the potential risks, patients may receive an additional 14 days of study therapy. In total, patients will be followed on study for 29 days post-randomization.

The RUXCOVID study is sponsored by Incyte in the United States, and Novartis outside of the United States.

About the Ruxolitinib Expanded Access Program (EAP) in COVID-19
The ruxolitinib Expanded Access Program (EAP) in COVID-19 for patients with severe COVID-19 associated cytokine storm allows eligible patients to receive ruxolitinib while it is being investigated in COVID-19 patients. Patients must be unable to participate in other clinical trials of ruxolitinib in COVID-19 to qualify for this EAP.

The most common side effects of Jakafi include: for certain types of MF and PV - low platelet or low red blood cell counts, bruising, dizziness, headache, and diarrhea; and for acute GVHD – low platelet, red or white blood cell counts, infections, and fluid retention.

These are not all the possible side effects of Jakafi. Ask your pharmacist or healthcare provider for more information. Tell your healthcare provider about any side effect that bothers you or that does not go away.

Before taking Jakafi, tell your healthcare provider about: all the medications, vitamins, and herbal supplements you are taking and all your medical conditions, including if you have an infection, have or had tuberculosis (TB), or have been in close contact with someone who has TB, have or had hepatitis B, have or had liver or kidney problems, are on dialysis, have a high level of fat in your blood (high blood cholesterol or triglycerides), had skin cancer or have any other medical condition.
