    SOUTH SAN FRANCISCO, Calif., March 11, 2021 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (NASDAQ:RIGL) today announced the completion of patient enrollment in a multi-center Phase 2 clinical trial to evaluate the safety of fostamatinib, Rigel's oral spleen tyrosine kinase (SYK) inhibitor, for the treatment of hospitalized COVID-19 patients. The study is sponsored by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health (NIH), in collaboration with Inova Health System. Fostamatinib is marketed in the U.S. as TAVALISSE® (fostamatinib disodium hexahydrate) tablets, and is approved in the U.S., Europe, and Canada as a treatment for adult chronic immune thrombocytopenia (ITP).

    The Phase 2 clinical trial is being conducted at the NIH Clinical Center in Bethesda, Maryland, the nation's largest hospital devoted entirely to clinical research, and Inova Fairfax Hospital. 

    This is a double-blind, placebo-controlled Phase 2 clinical trial that randomly assigned fostamatinib plus standard of care (SOC) or matched placebo plus SOC (1:1) to 58 evaluable patients who are a 5 to 7 on the 8-point ordinal scale (requiring supplemental oxygen via nasal canula or non-invasive ventilation, requiring mechanical ventilation or extracorporeal membrane oxygenation). Treatment will be administered orally twice daily for 14 days. There will be a follow-up period to day 60. The primary endpoint of this study is cumulative incidence of serious adverse events (SAE) through day 29, with multiple secondary endpoints designed to assess the early efficacy and clinically relevant endpoints of disease course as well as in vitro biological correlatives evaluating the effects of the drug on pathways involved in the pathophysiology of COVID-19, including NETosis. The NHLBI and Rigel expect to report topline data from this clinical trial in April 2021.

    About COVID-19 & SYK Inhibition

    COVID-19 is the infectious disease 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 resulting in endothelial dysfunction and subsequently micro and macrovascular thrombosis.1 Much of the underlying pathology of SARS-CoV-2 is thought to be secondary to a hyperinflammatory immune response associated with increased risk of thrombosis.2

    SYK is involved in the intracellular signaling pathways of many different immune cells. Therefore, SYK inhibition may improve outcomes in patients with COVID-19 via inhibition of key Fc gamma receptor (FcγR) and c-type lectin receptor (CLR) mediated drivers of pathology, such as inflammatory cytokine release by monocytes and macrophages, production of neutrophil extracellular traps (NETs) by neutrophils, and platelet aggregation.3,4,5 Furthermore, SYK inhibition in neutrophils and platelets may lead to decreased thromboinflammation, alleviating organ dysfunction in critically ill patients with COVID-19.

    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 in 1% 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 in 1% 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 (both 2%), neutropenia, arthralgia, chest pain, diarrhea, dizziness, nephrolithiasis, pain in extremity, toothache, syncope, and hypoxia (all 1%).
    • 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.

    SOUTH SAN FRANCISCO, Calif., March 2, 2021 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (NASDAQ:RIGL) today reported financial results for the fourth quarter and full year ended December 31, 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.

    "Our team has shown its resilience as we continue to execute on our mission to serve patients who have diseases where few or no approved treatment options exist," said Raul Rodriguez, Rigel's president and CEO. "Despite the challenges brought on by 2020, we successfully expanded our global ITP reach and positioned ourselves for potential success in wAIHA, announced a major collaboration with Lilly to develop RIP1 inhibitors, and launched a comprehensive COVID-19 clinical program which has gained the support from the NIH, DOD, and several universities. Importantly, we also continued to explore opportunities in immunology, and more recently heme-onc, with our IRAK 1/4 inhibitor program." 

    Business Update

    In February 2021, Rigel and Eli Lilly (Lilly) announced a global strategic collaboration to co-develop and commercialize R552, Rigel's receptor-interacting serine/threonine-protein kinase 1 (RIP1) inhibitor, for all indications, including autoimmune and inflammatory diseases. In addition, Lilly will lead the development and commercialization of all RIP1 inhibitors in central nervous system (CNS) indications. Under the terms of the agreement, Lilly will pay an upfront cash payment to Rigel of $125 million and is eligible to receive up to $835 million in potential development, regulatory and commercial milestone payments, as well as tiered royalties that will vary depending upon Rigel's clinical development investment.

    Rigel launched a Phase 3 clinical trial to evaluate fostamatinib for the treatment of hospitalized COVID-19 patients. The Phase 3 trial is designed to evaluate the safety and efficacy of fostamatinib in hospitalized COVID-19 patients without respiratory failure that have certain high-risk prognostic factors. This multi-center, double-blind, placebo-controlled, adaptive design study is expected to enroll over 300 evaluable patients that will be randomly assigned to either fostamatinib plus standard of care (SOC) or matched placebo plus SOC (1:1). Treatment will be administered orally twice daily for 14 days. There will be a follow-up period to day 60. The primary endpoint of this study is the proportion of subjects who progress to severe/critical disease within 29 days. 

    Rigel was awarded $16.5 million from the U.S. Department of Defense's (DOD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) to support Rigel's Phase 3 clinical trial of fostamatinib in hospitalized COVID-19 patients.

    The Phase 2 clinical trial of fostamatinib in hospitalized COVID-19 patients sponsored by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health (NIH), in collaboration with Inova Health System has currently enrolled 57 patients. This is a double-blind, placebo-controlled Phase 2 clinical trial that is randomly assigning fostamatinib plus standard of care (SOC) or matched placebo plus SOC (1:1) to approximately 60 evaluable patients who are a 5 to 7 on the 8-point ordinal scale (requiring supplemental oxygen via nasal canula or non-invasive ventilation, requiring mechanical ventilation or extracorporeal membrane oxygenation). The primary endpoint of this study is cumulative incidence of serious adverse events (SAE) through day 29. The NHLBI and Rigel expect to report topline data from this clinical trial in April 2021.

    Imperial College London's ongoing Phase 2 clinical trial of fostamatinib in hospitalized COVID-19 patients is a two-stage open label, controlled trial with patients randomized (1:1:1) to fostamatinib, ruxolitinib, or standard of care. The study has currently enrolled 106 patients. 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.

    Enrollment is progressing in Rigel's FORWARD study, a Phase 3 pivotal trial of TAVALISSE in warm autoimmune hemolytic anemia (wAIHA). The study has enrolled 66 of 90 patients targeted for enrollment. Rigel has reached agreement with the U.S. Food and Drug Administration (FDA) on the durable response measure for the primary efficacy endpoint of the study as well as the inclusion of additional secondary endpoints. The company recently announced that the FDA had granted Fast Track designation to TAVALISSE for the treatment of wAIHA. The FDA previously granted TAVALISSE Orphan Drug designation for this indication. If approved, TAVALISSE may be the first-to-market therapy for patients with wAIHA.

    Rigel continues to advance the development of its IRAK1/4 program, which includes R835, an orally available, potent and selective inhibitor that inhibits both IRAK1 and IRAK4. The company is currently identifying therapeutic opportunities in the areas of hematology/oncology and rare immunology diseases.

    In November 2020, Rigel and its partner Medison Pharma announced that Health Canada approved the new drug submission (NDS) for TAVALISSE for the treatment of thrombocytopenia in adult patients with chronic ITP who have had an insufficient response to other treatments. Medison is also anticipating a decision on a New Drug Application (NDA) in Israel in Q2 2021. In July 2020, Rigel and its partner Grifols S.A. announced the launch of TAVLESSE in Germany and the United Kingdom following approval by the European Commission in January 2020. Currently, TAVALISSE is in a Phase 3b clinical trial in Japan with Rigel's partner Kissei. This trial is required for approval by the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan.

    Financial Update

    For the fourth quarter of 2020, Rigel reported a net loss of $19.2 million, or $0.11 per share, compared to net loss of $17.2 million, or $0.10 per share, in the same period of 2019.

    In the fourth quarter of 2020, total revenues were $18.5 million, consisting of $17.8 million in TAVALISSE net product sales and $697,000 in contract revenues from collaborations. TAVALISSE net product sales of $17.8 million increased by 28% from $13.8 million in the fourth quarter of 2019. Contract revenues from collaborations of $697,000 for the fourth quarter of 2020 consisted of $500,000 from Grifols related to an option for commercialization in additional territories and $197,000 in revenues earned from the performance of certain research and development services from Rigel's collaboration agreement with Grifols.

    Rigel reported total costs and expenses of $37.3 million in the fourth quarter of 2020, compared to $32.7 million for the same period in 2019. The increase in costs and expenses was due to the increase in research and development costs primarily related to the continued work on Rigel's Phase 1 clinical trial in IRAK 1/4 inhibitor program, as well as its recently launched Phase 3 clinical trial for hospitalized COVID-19 patients, partially offset by the decrease in costs on Rigel's ongoing Phase 3 clinical trial in wAIHA.

    For the full year ended December 31, 2020, Rigel reported a net loss of $29.7 million, or $0.18 per share, compared to a net loss of $66.9 million, or $0.40 per share, for the same period of 2019.

    Rigel reported total revenues of $108.6 million for the year ended December 31, 2020, compared to $59.3 million in the same period of 2019.  Total revenues for the year ended December 31, 2020 consisted of $61.7 million in TAVALISSE net product sales and $46.9 million in contract revenues from collaborations. TAVALISSE net product sales of $61.7 million increased by 41% from $43.8 million in 2019. The increase in contract revenues from collaborations related to revenue from the upfront fee previously received in 2019, as well as the milestone payment received from Grifols in the first quarter of 2020 upon EC approval of the MAA for fostamatinib in Europe, and the $2.1 million in contract revenues for the achievement of a milestone in accordance with the amended license and collaboration agreement with Daiichi-Sankyo, partially offset by the developmental and commercial milestones from its various collaborative partners in 2019.

    Total costs and expenses for the year ended December 31, 2020, were $137.6 million, compared to $128.4 million, for the same period of 2019. The increase in total costs and expenses was primarily related to the increases in research and development costs due to the completion of Rigel's Phase 1 clinical trial in RIP1 inhibitor program, ongoing work on recently launched Phase 3 clinical trial for hospitalized COVID-19 patients, continued work on Rigel's Phase 1 clinical trial in IRAK 1/4 inhibitor program and ongoing Phase 3 clinical trials in wAIHA, as well as increases in personnel-related costs, partially offset by decreases in various third-party costs due to the COVID-19 pandemic.

    As of December 31, 2020, Rigel had cash, cash equivalents and short-term investments of $57.3 million, compared to $98.1 million as of December 31, 2019.

    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 are 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. 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. To date, there are no disease-targeted therapies approved for AIHA, despite the unmet medical need that exists for these patients. Warm antibody 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.

    About COVID-19 & SYK Inhibition

    COVID-19 is the infectious disease 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 resulting in endothelial dysfunction and subsequently micro and macrovascular thrombosis.1 Much of the underlying pathology of SARS-CoV-2 is thought to be secondary to a hyperinflammatory immune response associated with increased risk of thrombosis.2

    SYK is involved in the intracellular signaling pathways of many different immune cells. Therefore, SYK inhibition may improve outcomes in patients with COVID-19 via inhibition of key Fc gamma receptor (FcγR) and c-type lectin receptor (CLR) mediated drivers of pathology, such as inflammatory cytokine release by monocytes and macrophages, production of neutrophil extracellular traps (NETs) by neutrophils, and platelet aggregation.3,4,5 Furthermore, SYK inhibition in neutrophils and platelets may lead to decreased thromboinflammation, alleviating organ dysfunction in critically ill patients with COVID-19.

    About R5526

    The investigational candidate, R552, is an orally available, potent and selective inhibitor of receptor-interacting serine/threonine-protein kinase 1 (RIP1). RIP1 is believed to play a critical role in necroptosis. Necroptosis is a form of regulated cell death where the rupturing of cells leads to the dispersion of their inner contents, which induces immune responses and enhances inflammation. In preclinical studies, R552 prevented joint and skin inflammation in a RIP1-mediated murine model of inflammation and tissue damage. The safety and efficacy of R552 has not been established by the FDA or any healthcare authority.

    About R8356

    The investigational candidate, R835, is an orally available, potent and selective inhibitor of IRAK1 and IRAK4 that has been shown preclinically to block inflammatory cytokine production in response to toll-like receptor (TLR) and the interleukin-1 receptor (IL-1R) family signaling. TLRs and IL-1Rs play a critical role in the innate immune response, and dysregulation of these pathways can lead to a variety of inflammatory pathological conditions. R835 treatment demonstrates amelioration of clinical symptoms in multiple rodent models of inflammatory disease including psoriasis, arthritis, lupus, multiple sclerosis and gout. The safety and efficacy of R835 has not been established by the FDA or any healthcare authority.

    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 in 1% 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 in 1% 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 (both 2%), neutropenia, arthralgia, chest pain, diarrhea, dizziness, nephrolithiasis, pain in extremity, toothache, syncope, and hypoxia (all 1%).
    • 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.

    INDIANAPOLIS and SOUTH SAN FRANCISCO, Calif., Feb. 18, 2021 /PRNewswire/ -- Eli Lilly and Company (NYSE:LLY) and Rigel Pharmaceuticals, Inc. (NASDAQ:RIGL) today announced a global exclusive license agreement and strategic collaboration to co-develop and commercialize Rigel's R552, a receptor-interacting serine/threonine-protein kinase 1 (RIPK1) inhibitor, for all indications including autoimmune and inflammatory diseases. Pursuant to the collaboration, Lilly will also lead all clinical development of brain penetrating RIPK1 inhibitors in central nervous system (CNS) diseases.

    Rigel's lead RIPK1 inhibitor, R552, has completed Phase 1 clinical trials and will begin Phase 2 clinical trials in 2021 as part of the collaboration.  Rigel also has ongoing pre-clinical activities with its lead CNS penetrant RIPK1 inhibitor candidates.

    Under the terms of the agreement, Lilly will pay an upfront cash payment to Rigel of $125 million. Rigel may also be eligible to receive up to $835 million in potential development, regulatory, and commercial milestone payments, as well as tiered royalties ranging from the mid-single digit to high-teens that will vary depending upon Rigel's clinical development investment. Lilly and Rigel will co-develop R552 at specified contribution levels. Lilly will be responsible for all costs of global commercialization for R552, and Rigel will have the right to co-commercialize R552 in the U.S. Lilly will be solely responsible for all clinical development and commercialization of brain penetrating RIPK1 inhibitors in CNS indications.

    RIPK1 is a critical signaling protein implicated in a broad range of key inflammatory cellular processes including necroptosis, a type of regulated cell death, and cytokine production. In necroptosis, cells rupture leading to the dispersion of cell contents which can trigger an immune response and enhance inflammation. Inhibiting RIPK1 may be a new approach to treating various autoimmune, inflammatory, and neurodegenerative disorders. In pre-clinical studies, Rigel's R552 demonstrated prevention of joint and skin inflammation in a RIPK1-mediated murine model of inflammation and tissue damage.

    "At Lilly, our immunology strategy is focused on the pursuit of novel targets that have the potential to develop into best-in-class medicines for patients with autoimmune conditions," said Ajay Nirula, M.D., Ph.D., vice president of immunology at Lilly. "RIPK1 inhibitors are a promising approach, and R552 is an exciting addition to our immunology pipeline. We look forward to working with Rigel to advance its clinical development."

    "We are very excited to form this strategic partnership with Lilly. This collaboration will provide significant resources and expertise to support a broad investigation in multiple disease indications with our RIPK1 inhibitors," said Raul Rodriguez, Rigel's president and CEO. "With Lilly's extensive knowledge in immune and CNS diseases, they are our ideal partner to ensure the clinical and commercial success of our RIPK1 inhibitor program."

    This transaction is subject to customary closing conditions, including clearance under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976. This transaction will be reflected in Lilly's reported results and financial guidance according to Generally Accepted Accounting Principles (GAAP). There will be no change to Lilly's 2021 non-GAAP earnings per share guidance as a result of this transaction.
