[Variable opening message]
- I know you have many options for chronic ITP treatment. I’d like to share some information regarding the improvements in platelet counts across different lines of therapy.
- Thank you for your time earlier. Following up on our conversation, I wanted to share some compelling data for TAVALISSE by line of therapy.
- As your representative for TAVALISSE with Rigel Pharmaceuticals, I wanted to provide you with insights into the efficacy across different lines of therapy for your patients with chronic ITP.
- I hope you’ve been doing well. I wanted to bring your attention to the efficacy of TAVALISSE and the improvement in platelet counts across lines of therapy.
- I wanted to reach out to make sure you were aware of the additional data for TAVALISSE by different lines of therapy.

| Early treatment with spleen tyrosine kinase (SYK) inhibition may limit platelet destruction in patients
with chronic immune thrombocytopenia (ITP).1
|
|
Indication
|
| TAVALISSE 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.
|
|
SELECT IMPORTANT SAFETY INFORMATION
|
| 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.
|
Please see additional Important Safety Information below.
| The Fostamatinib in ITP (FIT) Program was designed to evaluate the short- and long-term treatment effects of TAVALISSE in 2 double-blind, placebo-controlled studies of 150 adults with chronic ITP who had received prior therapy, followed by an open-label extension study.2,3

Primary endpoint—stable response: 17% vs Placebo 2%1,2,4*

| - |
Median post-baseline platelet count: 97 x 109/L |
| - |
Platelet counts ≥50 x 109/L during weeks 14-24 (at least 4 of 6 consecutive visits) |
|
| Post hoc endpoint—overall response: 43% vs Placebo 14%2,4† |
| - |
Median post-baseline platelet count: 49 x 109/L |
| - |
At least one platelet count ≥50 x 109/L during weeks 0-12 |
|
| A post hoc analysis of the FIT Program was published in the British Journal of Haematology, evaluating patient response to treatment by line of therapy. The authors of this analysis “hypothesize that early treatment of ITP with SYK inhibition may interrupt disease progression by blocking phagocytosis of antibody-coated platelets and thus subsequent events.”4
|
| * |
Stable platelet response: achievement of a platelet count ≥50 x 109/L on ≥4 of the 6 visits during weeks 14-24 without need for rescue treatment.
|
| † |
Overall response: achievement of a platelet count ≥50 x 109/L at least once during the first 3 months/12 weeks without need for rescue treatment.

Indication
TAVALISSE 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.
