Generic Sprycel Information

Introduction

Sprycel (dasatinib) is an oral tyrosine‑kinase inhibitor indicated for the treatment of certain leukemias. It is manufactured by Bristol‑Myers Squibb and belongs to the cancer‑therapy drug class. In Hong Kong, Sprycel is prescribed for chronic myeloid leukaemia (CML) and Ph‑positive acute lymphoblastic leukaemia (ALL) after verification by a qualified haematologist. The medication targets abnormal cellular pathways that drive uncontrolled blood‑cell proliferation, offering a targeted option beyond conventional chemotherapy.

What is Sprycel?

Sprycel is a small‑molecule inhibitor of the BCR‑ABL tyrosine‑kinase and several other kinases involved in leukemic cell growth. It was approved by the U.S. Food and Drug Administration (FDA) in 2006 and subsequently received regulatory clearance in the European Union, Japan, and Hong Kong. The drug is supplied as film‑coated tablets in strengths of 25 mg, 50 mg, 75 mg, and 100 mg. Although Sprycel is the proprietary brand name, the active ingredient is dasatinib, which is also available as a generic medication from licensed manufacturers worldwide.

How Sprycel Works

Dasatinib binds to the ATP‑binding pocket of the BCR‑ABL fusion protein with high affinity, preventing phosphorylation of downstream substrates that normally trigger cell division. By inhibiting BCR‑ABL, as well as the Src family kinases, c‑Kit and PDGFR, Sprycel halts the signal transduction cascade that sustains malignant hematopoietic clones. The drug is absorbed quickly after oral administration, reaching peak plasma concentrations in 1–3 hours. Its elimination half‑life ranges from 3 to 5 hours, and hepatic CYP3A4 enzymes mediate metabolism, allowing predictable pharmacokinetics for once‑daily dosing.

Conditions Treated with Sprycel

• Chronic Myeloid Leukaemia (CML), chronic phase – Sprycel is approved for patients who are newly diagnosed or who have shown resistance or intolerance to first‑line therapy (imatinib).
• CML, accelerated or blast phase – The drug is recommended when disease progresses despite prior treatment.
• Ph‑positive Acute Lymphoblastic Leukaemia (ALL) – Used in combination with chemotherapy for adult patients whose leukemic cells express the Philadelphia chromosome.

In Hong Kong, CML accounts for approximately 2‑3 % of all haematologic malignancies, translating to several hundred newly diagnosed cases annually. The targeted action of Sprycel improves long‑term cytogenetic and molecular response rates, reducing the need for bone‑marrow transplantation in many patients.

Who is Sprycel For?

• Adults (≥18 years) with confirmed BCR‑ABL‑positive CML in chronic, accelerated, or blast phase.
• Adults with Ph‑positive ALL who have achieved an initial remission and require consolidation therapy.
• Patients who cannot tolerate first‑generation BCR‑ABL inhibitors (e.g., imatinib) due to adverse reactions or suboptimal response.
• Individuals with adequate hepatic and renal function (bilirubin ≤1.5 × ULN, creatinine clearance ≥30 mL/min) and no contraindicated drug interactions.

Sprycel is not appropriate for:

• Pregnant or breastfeeding women (category D).
• Patients with a history of severe cardiac arrhythmias or uncontrolled hypertension.
• Individuals receiving strong CYP3A4 inducers (e.g., rifampin) without dose adjustment.

Risks, Side Effects, and Interactions

Common

• Myelosuppression (neutropenia, thrombocytopenia, anemia) – laboratory monitoring required weekly during the first two months.
• Fluid retention (pleural effusion, peripheral edema) – dose interruption often resolves symptoms.
• Gastrointestinal upset (nausea, diarrhea, abdominal pain).
• Rash or skin discoloration – usually mild and self‑limited.

Rare

• Pulmonary arterial hypertension – reported in long‑term users; echocardiogram recommended if dyspnoea develops.
• Severe hemorrhage – particularly in patients on anticoagulants; monitor coagulation parameters.
• Pancreatitis – abdominal pain with elevated amylase/lipase warrants discontinuation.

Serious

• Life‑threatening infections due to profound neutropenia; prompt antimicrobial therapy essential.
• Cardiac toxicity (QT‑interval prolongation, ventricular tachyarrhythmias). Baseline ECG and periodic monitoring advised.
• Severe liver injury (transaminase elevations >5 × ULN) – may require permanent cessation.

Drug–Drug Interactions

• Strong CYP3A4 inhibitors (ketoconazole, clarithromycin) increase dasatinib exposure; dose reduction recommended.
• CYP3A4 inducers (carbamazepine, St. John’s wort) lower exposure; avoid or consider alternative therapy.
• Antacids containing aluminum or magnesium, as well as proton‑pump inhibitors, can reduce absorption; take Sprycel at least 2 hours before or after such agents.
• Concomitant use with anticoagulants (warfarin, direct oral anticoagulants) amplifies bleeding risk; close INR or anti‑Xa monitoring required.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose for CML (chronic phase): 100 mg once daily on an empty stomach (≥2 hours before or after meals).
• Accelerated/blast phase or Ph‑positive ALL: 140 mg once daily, administered with the same fasting conditions.
• Renal impairment (CrCl 30‑59 mL/min): 80 mg daily (CML) or 100 mg daily (accelerated/blast phase).
• Hepatic impairment (bilirubin ≤1.5 × ULN): No dose change; monitor liver enzymes.

Missed dose: Take the missed tablet as soon as remembered provided it is at least 6 hours before the next scheduled dose. If the timing is close, skip the missed dose and resume the regular schedule; do not double‑dose.

Overdose: Acute ingestion of >200 mg may increase the risk of severe myelosuppression and cardiac toxicity. Seek emergency medical attention; supportive care includes activated charcoal (if within 2 hours), hydration, and continuous cardiac monitoring.

Food & Alcohol: High‑fat meals markedly reduce dasatinib absorption; patients should avoid taking Sprycel with meals. Moderate alcohol consumption is permissible but excessive drinking may exacerbate hepatic toxicity.

FAQ

• What tablet strengths are available for Sprycel?
  Sprycel is marketed in 25 mg, 50 mg, 75 mg, and 100 mg film‑coated tablets. The appropriate strength is selected by the treating physician based on disease phase and patient tolerance.

• Can Sprycel be stored in a refrigerator?
  No. Sprycel should be kept at controlled room temperature (15 °C‑30 °C). Refrigeration can alter tablet integrity and affect dissolution.

• Does the generic dasatinib have the same inactive ingredients as the brand?
  Generic formulations contain pharmaceutically equivalent inactive excipients, but the exact composition may differ (e.g., microcrystalline cellulose vs. lactose). All excipients used are approved by health authorities for oral use.

• Is it safe to travel internationally with Sprycel?
  Yes, provided the medication remains in its original labeled container, is stored at room temperature, and a copy of the prescription or medical letter is carried. Be aware of customs regulations in destination countries regarding import of oncology drugs.

• How does Sprycel compare with imatinib in terms of efficacy?
  Clinical trials (e.g., CA180‑034) demonstrated faster and deeper molecular responses with dasatinib versus imatinib in newly diagnosed CML patients, especially in those with high‑risk disease characteristics.

• Are there any dietary restrictions while taking Spryzer?
  Patients should avoid taking Sprycel with high‑fat meals because fat reduces drug absorption. A light, low‑fat snack is permissible if taken at least 2 hours before or after the dose.

• Can Sprycel cause hair loss?
  Hair thinning has been reported occasionally, but it is not a common side effect. If significant alopecia occurs, the physician may assess dose adjustment or supportive measures.

• What monitoring is required during treatment?
  Baseline CBC, liver function tests, renal function, ECG, and lipid profile are recommended. CBC is repeated weekly for the first two months, then every 2–4 weeks thereafter.

• Does Sprycel interact with herbal supplements?
  St. John’s wort, a CYP3A4 inducer, can lower dasatinib plasma levels and reduce efficacy. Patients should disclose any herbal products to their healthcare team.

• Is Sprycel covered by Hong Kong’s public health insurance scheme?
  Coverage varies; some patients receive subsidies through Hospital Authority programmes, while others rely on private payment. Eligibility is determined by the treating institution and the patient’s insurance status.

• What should I do if I experience a severe rash?
  Discontinue Sprycel immediately and seek medical attention. A severe or bullous rash may indicate a hypersensitivity reaction requiring systemic treatment and a possible switch to an alternative kinase inhibitor.
