SOUTH SAN FRANCISCO, Calif., Aug. 4, 2020 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL) today reported financial results for the second quarter ended June 30, 2020, including sales of TAVALISSE® (fostamatinib disodium hexahydrate) tablets, for the treatment of adults with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment.
"During the second quarter we achieved significant progress across all aspects of our business, despite the challenges resulting from the COVID-19 pandemic," said Raul Rodriguez, Rigel's president and CEO. "Sales of TAVALISSE increased during the quarter and in July, the product became available in initial European markets. We continued to advance our pipeline, most recently with the launch of an investigator-sponsored trial in COVID-19 pneumonia. We believe there is clear scientific rationale to explore the potential of SYK-inhibition to treat these patients and possibly prevent severe respiratory conditions resulting from COVID-19. We will continue to pursue opportunities to expand these efforts."
COVID-19 Program Highlights
Rigel announced a Phase 2 investigator-sponsored trial (IST) with Imperial College London to evaluate the efficacy of fostamatinib for the treatment of COVID-19 pneumonia. The IST is a two-stage, open label, controlled clinical trial with patients randomized (1:1:1) to fostamatinib, ruxolitinib, or standard of care. Treatment will be administered twice daily for 14 days and patients will receive a follow-up assessment at day 14 and day 28 after the first dose. The primary objective will be to determine the efficacy of fostamatinib and the efficacy of ruxolitinib compared to standard of care to reduce the proportion of hospitalized patients progressing from mild or moderate to severe COVID-19 pneumonia. Rigel will provide support for this trial along with Novartis.
Recent in vitro studies led by the Amsterdam University Medical Center at the University of Amsterdam, showed that R406, the active metabolite of fostamatinib, blocked macrophage hyperinflammatory responses to a combination of immune complexes formed by anti-Spike IgG in serum from severe COVID-19 patients. Anti-Spike IgG levels are known to correlate with the severity of COVID-19. These results suggest that by inhibiting anti-Spike IgG-mediated hyperinflammation, R406 could potentially play a role in the prevention of cytokine storms as well as pulmonary edema and thrombosis associated with severe COVID-19.1
In addition, researchers at The Broad Institute of the Massachusetts Institute of Technology (MIT) and Harvard led a recent screen to identify FDA-approved compounds that reduce mucin-1 (MUC1) protein abundance. MUC1 is a biomarker used to predict the development of ALI and ARDS and correlates with poor clinical outcomes. Of the 3,713 compounds that were screened, fostamatinib was the only compound identified which both decreased expression of MUC1 and is FDA approved. Fostamatinib demonstrated preferential depletion of MUC1 from epithelial cells without affecting cell viability. The research was focused on drug repurposing for the much lower risk of toxicity and the ability of FDA-approved treatments to be delivered on a shortened timescale, which is critical for patients afflicted with lung disease resulting from COVID-19.2
Business Update
Post-hoc data analysis from Rigel's previous Phase 3 clinical program of TAVALISSE in adult patients with chronic ITP, which highlights the potential benefit of use in earlier lines of therapy, was published in the British Journal of Haematology. Inclusion in one of the leading peer-reviewed journals in the field of hematology underscores the significance of the
Grifols S.A., Rigel's collaborator in Europe, launched fostamatinib disodium hexahydrate in Germany and the United Kingdom in July, under the European brand name TAVLESSE. TAVLESSE is indicated in Europe for the treatment of chronic ITP in adult patients who are refractory to other treatments.
Clinical trial sites in Rigel's FORWARD study, a Phase 3 pivotal trial of TAVALISSE in warm autoimmune hemolytic anemia (wAIHA), are now mostly open and enrolling patients after a temporary postponement due to the COVID-19 pandemic. Currently, the FORWARD study has enrolled 44 of the 90 patients targeted for enrollment and has over 90 active clinical trial sites established across 22 countries with incremental sites being added.
At the European League Against Rheumatism (EULAR) 2020 E-Congress in June, Rigel presented two oral and two poster presentations highlighting its investigational compound R835, a potent and selective inhibitor of both interleukin receptor associated kinase (IRAK)1 and IRAK4. In multiple pre-clinical rodent models of acute and chronic inflammation, R835 administration resulted in reduced inflammation, and in Phase 1 human studies it showed encouraging pharmacokinetic properties.
Rigel has appointed Dave Santos as executive vice president and chief commercial officer. Mr. Santos joins Rigel with over 30 years of commercial experience in the biopharmaceutical industry with companies such as Bristol-Myers Squibb, Lilly, Genentech, and most recently Jazz Pharmaceuticals, where he led the Hematology/Oncology Business Unit. He has a robust track record in sales and marketing leadership roles, building commercial capabilities, and growing brands in the hematology-oncology area, where he has spent most of his career.

About ITP
In patients with ITP (immune thrombocytopenia), the immune system attacks and destroys the body's own blood platelets, which play an active role in blood clotting and healing. Common symptoms of ITP include fatigue, excessive bruising and bleeding. People suffering with chronic ITP may live with an increased risk of severe bleeding events that can result in serious medical complications or even death. In addition to fostamatinib, current therapies for ITP include steroids, blood platelet production boosters (TPO-RAs) and splenectomy. However, not all patients respond to existing therapies. As a result, there remains a significant medical need for additional treatment options for patients with ITP.
About AIHA
Autoimmune hemolytic anemia (AIHA) is a rare, serious blood disorder in which the immune system produces antibodies that result in the destruction of the body's own red blood cells. AIHA affects approximately 45,000 adult patients in the U.S. and can be a severe, debilitating disease. Warm AIHA (wAIHA), the most common form of AIHA, is characterized by the presence of antibodies that react with the red blood cell surface at body temperature. To date, there are no disease-targeted therapies approved for AIHA, despite the unmet medical need that exists for these patients.
About Coronavirus Disease 2019 (COVID-19) & SYK-Signaling
COVID-19 is caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). SARS-CoV-2 primarily infects the upper and lower respiratory tract and can lead to acute respiratory distress syndrome (ARDS). Additionally, some patients develop other organ dysfunction including myocardial injury, acute kidney injury, shock along with endothelial dysfunction and subsequently micro and macrovascular thrombosis.3 Much of the underlying pathology of SARS-CoV-2 is thought to be secondary to a dysregulated immune response and more recently a hypercoagulable state leading to immunothrombosis.4
Spleen tyrosine kinase (SYK) is involved in the intracellular signaling pathways of many different immune cells. SYK inhibition may improve outcomes in patients with COVID-19 by biological mechanisms which include the inhibition of pro-inflammatory cytokines by monocytes and macrophages, decreased production of neutrophil extracellular traps (NETs) by neutrophils, and inhibition of platelet aggregation; three pathways that are mediated through Fc receptors (FcR) recognition of antigen-antibody complexes or activation of c-type lectin receptors (CLEC).1 In monocytes and macrophages, SYK mediates the pro-inflammatory process through the production of pro-inflammatory cytokines. The production of pro-inflammatory cytokines has been reversed with the inhibition of SYK in MERS-CoV infected macrophages.5
About TAVALISSE
Indication
TAVALISSE® (fostamatinib disodium hexahydrate) tablets is indicated for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment.
Important Safety Information
Warnings and Precautions
- Hypertension can occur with TAVALISSE treatment. Patients with pre-existing hypertension may be more susceptible to the hypertensive effects. Monitor blood pressure every 2 weeks until stable, then monthly, and adjust or initiate antihypertensive therapy for blood pressure control maintenance during therapy. If increased blood pressure persists, TAVALISSE interruption, reduction, or discontinuation may be required.
- Elevated liver function tests (LFTs), mainly ALT and AST, can occur with TAVALISSE. Monitor LFTs monthly during treatment. If ALT or AST increase to >3 x upper limit of normal, manage hepatotoxicity using TAVALISSE interruption, reduction, or discontinuation.
- Diarrhea occurred in
31% of patients and severe diarrhea occurred in1% of patients treated with TAVALISSE. Monitor patients for the development of diarrhea and manage using supportive care measures early after the onset of symptoms. If diarrhea becomes severe (≥Grade 3), interrupt, reduce dose or discontinue TAVALISSE. - Neutropenia occurred in
6% of patients treated with TAVALISSE; febrile neutropenia occurred in1% of patients. Monitor the ANC monthly and for infection during treatment. Manage toxicity with TAVALISSE interruption, reduction, or discontinuation. - TAVALISSE can cause fetal harm when administered to pregnant women. Advise pregnant women the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment and for at least 1 month after the last dose. Verify pregnancy status prior to initiating TAVALISSE. It is unknown if TAVALISSE or its metabolite is present in human milk. Because of the potential for serious adverse reactions in a breastfed child, advise a lactating woman not to breastfeed during TAVALISSE treatment and for at least 1 month after the last dose.
Drug Interactions
- Concomitant use of TAVALISSE with strong CYP3A4 inhibitors increases exposure to the major active metabolite of TAVALISSE (R406), which may increase the risk of adverse reactions. Monitor for toxicities that may require a reduction in TAVALISSE dose.
- It is not recommended to use TAVALISSE with strong CYP3A4 inducers, as concomitant use reduces exposure to R406.
- Concomitant use of TAVALISSE may increase concentrations of some CYP3A4 substrate drugs and may require a dose reduction of the CYP3A4 substrate drug.
- Concomitant use of TAVALISSE may increase concentrations of BCRP substrate drugs (eg, rosuvastatin) and P-Glycoprotein (P-gp) substrate drugs (eg, digoxin), which may require a dose reduction of the BCRP and P-gp substrate drug.
Adverse Reactions
- Serious adverse drug reactions in the ITP double-blind studies were febrile neutropenia, diarrhea, pneumonia, and hypertensive crisis, which occurred in
1% of TAVALISSE patients. In addition, severe adverse reactions occurred including dyspnea and hypertension (both2% ), neutropenia, arthralgia, chest pain, diarrhea, dizziness, nephrolithiasis, pain in extremity, toothache, syncope, and hypoxia (all1% ). - Common adverse reactions (≥
5% and more common than placebo) from FIT-1 and FIT-2 included: diarrhea, hypertension, nausea, dizziness, ALT and AST increased, respiratory infection, rash, abdominal pain, fatigue, chest pain, and neutropenia.
