Novartis announced plans to initiate a Phase III clinical trial in collaboration with Incyte to evaluate the use of Jakavi® (ruxolitinib) for treatment of a type of severe immune overreaction called cytokine storm that can lead to life-threatening respiratory complications in patients with COVID-19.
The decision is based on pre-clinical evidence and preliminary reports from independent studies, and is supported by extensive data on the safety and efficacy of Jakavi in conditions like acute graft versus host disease and myeloproliferative neoplasms. The proposed trial will assess Jakavi in combination with standard of care (SoC) therapy, compared to SoC therapy alone, in patients with severe COVID-19 pneumonia as a result of SARS-CoV-2 infection.
“Novartis is taking a number of steps to address the urgent needs arising from the COVID-19 pandemic, including the evaluation of our existing therapies to assess if any can be utilized beyond their approved indications,” said John Tsai, Head Global Drug Development and Chief Medical Officer, Novartis. “The potential that Jakavi could lead to faster recovery times for COVID-19 patients with fewer requiring intensive care and mechanical ventilation is encouraging and absolutely merits further investigation. We now are moving rapidly to finalize the study plan and then to enroll eligible patients, as well as put in place a process to provide access for patients unable to participate in the trial.”
Given the rapid spread of the pandemic, and as plans for the study are finalized, Novartis also has set up an international compassionate use program for eligible patients, subject to local regulations. In addition, we are taking steps to manage the anticipated increase in COVID-19 related requests for Jakavi without interrupting access for patients taking the drug for its licensed indications. In the US, ruxolitinib access requests are coordinated by Incyte.

Novartis announced a broad set of measures including the creation of a global fund of $20 million to support communities around the world impacted by the COVID-19 pandemic. Novartis also has committed 130 million doses of hydroxychloroquine to support pandemic response. Additionally, the company joined two key cross-industry research initiatives, the COVID-19 Therapeutics Accelerator, coordinated by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard, as well as a COVID-19 directed partnership organized by the Innovative Medicines Initiative (IMI). Novartis is separately supporting COVID-19 related clinical investigations of several Novartis medicines. To support access, the Novartis generics and biosimilars division Sandoz became the first company to commit to keeping stable prices for a basket of essential medicines that may help in the treatment of COVID-19.
Jakavi (ruxolitinib) is an oral inhibitor of the JAK 1 and JAK 2 tyrosine kinases. Jakavi is approved by the European Commission for the treatment of adult patients with polycythemia vera (PV) who are resistant to or intolerant of hydroxyurea and for the treatment of disease-related splenomegaly or symptoms in adult patients with primary myelofibrosis (MF) (also known as chronic idiopathic MF), post-polycythemia vera MF or post-essential thrombocythemia MF. Jakavi is approved in 101 countries for patients with MF, including EU countries, Switzerland, Canada, Japan and in more than 75 countries for patients with PV, including EU countries, Switzerland, Japan and Canada. The exact indication for Jakavi varies by country. Additional worldwide regulatory filings are underway in MF and PV.
Novartis licensed ruxolitinib from Incyte Corporation for development and commercialization in selected indications outside the United States. Ruxolitinib is marketed in the United States by Incyte Corporation as Jakafi® for patients with PV who have had an inadequate response to or are intolerant of hydroxyurea, for patients with intermediate or high-risk MF, and steroid-refractory acute GvHD in adult and pediatric patients 12 years and older.
The recommended starting dose of Jakavi in PV is 10 mg given orally twice daily. The recommended starting dose of Jakavi in MF is 15 mg given orally twice daily for patients with a platelet count between 100,000 cubic millimeters (mm) and 200,000 mm, and 20 mg twice daily for patients with a platelet count of >200,000 mm. Doses may be titrated based on safety and efficacy. There is limited information to recommend a starting dose for MF and PV patients with platelet counts between 50,000/mm and <100,000/mm. The maximum recommended starting dose in these patients is 5 mg twice daily, and patients should be titrated cautiously.
Jakavi is a registered trademark of Novartis AG in countries outside the United States. Jakafi is a registered trademark of Incyte Corporation. The safety and efficacy profile of Jakavi has not yet been established outside of its approved indications.
