SOUTH SAN FRANCISCO, Calif., May 3, 2022 /PRNewswire/ -- Rigel Pharmaceuticals, Inc. (Nasdaq: RIGL) today reported financial results for the first quarter ended March 31, 2022, 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.
"Rigel delivered on a solid quarter of TAVALISSE sales in ITP, and we believe we are well positioned for increasing sales in upcoming quarters," said Raul Rodriguez, Rigel's president and CEO. "wAIHA is a highly synergistic indication to ITP and we are very excited to be reporting Phase 3 fostamatinib results from our wAIHA trial in mid-2022. If approved, the addition of fostamatinib as a first-to-market therapy in wAIHA is a key next step in building a world-class hem-onc franchise."
- In the first quarter of 2022, 1,836 bottles of TAVALISSE were shipped directly to patients and clinics, representing the highest number of bottles shipped to patients and clinics in a quarter since launch and an increase of
15% compared to the first quarter of 2021. Rigel believes these achievements are the result of several factors, including Rigel's salesforce expansion completed in September 2021 and a substantial increase in in-person physician interactions in the quarter, and an expansion of market access for TAVALISSE to now include broad commercial coverage, with preferred status on three key national formularies. - Rigel is on track to report topline data from its FORWARD trial, a pivotal Phase 3 clinical trial of fostamatinib, an oral SYK inhibitor, in patients with wAIHA in mid-2022. If the data is positive, Rigel expects to proceed with regulatory filings and if approved, fostamatinib has the potential to be the first-to-market therapy for patients with wAIHA in 2023.
- In the first quarter of 2022, Rigel announced the publication of data in the American Journal of Hematology from the open label, multicenter, Phase 2 clinical study of fostamatinib in adults with wAIHA who had failed at least one prior treatment.
- Rigel's pivotal Phase 3 clinical trial evaluating fostamatinib in high-risk patients hospitalized with COVID-19 has enrolled 268 of the targeted 308 patients as of May 2, 2022. Due to the recent decline in COVID-19 hospitalizations, Rigel is reviewing strategies to complete enrollment and report topline results before the end of the year, including potentially completing the trial with fewer patients than the initial targeted enrollment of 308 patients.
- New data on fostamatinib in hospitalized patients with COVID-19 will be presented by collaborators from the National Institutes of Health and Inova Fairfax Hospital at the American Thoracic Society 2022 Annual Meeting being held in San Francisco, May 13 – 18, 2022.
- Startup activities are ongoing in Rigel's open-label, Phase 1b clinical trial of R289, a potent and selective IRAK1/4 inhibitor, in patients with lower-risk myeloid dysplastic syndrome (LR-MDS) who are refractory/resistant to prior therapies. The primary endpoint for this trial is safety with key secondary endpoints including preliminary efficacy and evaluation of pharmacokinetic properties. Rigel will also collect key biomarker data to further characterize R289's mechanism of action in LR-MDS.
- Partner Eli Lilly continues to advance R552, a potent and selective RIPK1 inhibitor, with the initial Phase 2 study in an immunologic disease indication now anticipated to begin in the first quarter of 2023. RIPK1 is implicated in a broad range of key inflammatory cellular processes and plays a key role in tumor necrosis factor (TNF) signaling, especially in the induction of pro-inflammatory necroptosis.
- On April 27, 2022, Rigel's partner Kissei Pharmaceutical Co., Ltd. (Kissei) announced that a new drug application (NDA) was submitted to Japan's Pharmaceuticals and Medical Devices Agency (PMDA) for fostamatinib in chronic ITP. Rigel has an exclusive license and supply agreement with Kissei to develop and commercialize fostamatinib in all current and potential indications in Japan, China, Taiwan and the Republic of Korea.

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.
Autoimmune hemolytic anemia (AIHA) is a rare, serious blood disorder in which the immune system produces antibodies that lead to the destruction of the body's own red blood cells. Warm antibody AIHA (wAIHA), which is the most common form of AIHA, is characterized by the presence of antibodies that react with the red blood cell surface at body temperature. wAIHA affects approximately 36,000 adult patients in the U.S.1 and can be a severe, debilitating disease. To date, there are no disease-targeted therapies approved for wAIHA, despite the unmet medical need that exists for these patients.
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.2 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.3
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 pro-inflammatory cytokine release by monocytes and macrophages, production of neutrophil extracellular traps (NETs) by neutrophils, and platelet aggregation. 4,5,6,7 Furthermore, SYK inhibition in neutrophils and platelets may lead to decreased thrombo-inflammation, alleviating organ dysfunction in critically ill patients with COVID-19.

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.
- 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.
- 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.
- 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.
