Generic Leukeran Information

Introduction

Leukeran is an oral chemotherapy medication whose active ingredient is chlorambucil, a cytotoxic alkylating agent. It belongs to the cancer drug group and is primarily used to treat certain lymphoid malignancies, most notably chronic lymphocytic leukemia (CLL) and Hodgkin lymphoma that have not responded to first‑line therapy. In Hong Kong, Leukeran is listed on the Hospital Authority’s formulary and is prescribed by hematologists for patients who meet specific clinical criteria. The drug is marketed by Bristol‑Myers Squibb and, although a brand name, contains the same chemical entity as generic chlorambucil products available worldwide.

What is Leukeran?

Leukeran is the trade name for chlorambucil tablets. Chemically it is a nitrogen‑mustard alkylating compound first synthesized in the 195s and subsequently developed as a systemic antineoplastic agent. The medication is classified as an alkylating agent within the broader chemotherapy class, acting by covalently binding DNA and interrupting cell division. Bristol‑Myers Squibb holds the original brand‑name registration for Leukeran in many jurisdictions, including Hong Kong, while generic forms of chlorambucil are produced by a range of reputable pharmaceutical manufacturers. Our online pharmacy supplies both the branded and generic versions, providing patients with a cost‑effective alternative that contains the identical active substance.

How Leukeran Works

Chlorambucil exerts its antitumor effect through irreversible alkylation of the guanine bases in DNA. By forming inter‑strand cross‑links, the drug prevents DNA replication and transcription, leading to apoptosis of rapidly proliferating cells, especially malignant lymphocytes. After oral ingestion, Leukeran is rapidly absorbed from the gastrointestinal tract, reaching peak plasma concentrations within 2–4 hours. The compound undergoes hepatic metabolism, primarily via cytochrome P450 enzymes, and is eliminated in the urine as unchanged drug and metabolites. The elimination half‑life ranges from 1 to 2 days, allowing for once‑daily dosing schedules. Because normal bone‑marrow cells also divide rapidly, the therapeutic window is narrow; careful dose titration is essential to maximize tumor control while minimizing myelosuppression.

Conditions Treated with Leukeran

• Chronic Lymphocytic Leukemia (CLL) / Small Lymphocytic Lymphoma (SLL): Leukeran is a first‑line oral agent for many CLL patients, especially those with early‑stage disease or comorbidities that preclude more aggressive regimens. In Hong Kong, CLL accounts for roughly 13 % of all adult leukemias, translating to several hundred new cases per year.
• Hodgkin Lymphoma (relapsed or refractory): When standard ABVD‑based therapy fails, low‑dose chlorambucil can be employed as part of salvage protocols.
• Indolent Non‑Hodgkin Lymphomas (e.g., follicular lymphoma) in selected cases: Although not first‑line, Leukeran may be used for patients who require a gentler oral regimen.

The drug’s oral route, predictable pharmacokinetics, and modest toxicity profile make it suitable for outpatient management, a key consideration in the densely populated health system of Hong Kong.

Who is Leukeran For?

Leukeran is indicated for adult patients with confirmed CLL or SLL who require systemic therapy, as well as for selected individuals with relapsed Hodgkin or indolent non‑Hodgkin lymphoma. Ideal candidates are those who:

• Have adequate baseline bone‑marrow reserve (absolute neutrophil count ≥ 1.5 × 10⁹/L, platelet count ≥ 100 × 10⁹/L).
• Exhibit disease that is clinically progressive or symptomatic (e.g., lymphadenopathy, cytopenias, or constitutional symptoms).
• Cannot tolerate intravenous chemotherapy due to comorbidities, frailty, or personal preference for oral therapy.

Leukeran is not appropriate for pregnant or breastfeeding women, patients with severe hepatic or renal impairment without dose adjustment, and individuals with active uncontrolled infections or known hypersensitivity to nitrogen‑mustard agents. Clinicians also avoid it in patients receiving concurrent high‑dose myelosuppressive drugs unless strict monitoring protocols are in place.

Risks, Side Effects, and Interactions

Common

• Myelosuppression: Neutropenia, anemia, and thrombocytopenia are the most frequently observed laboratory changes, typically emerging after 2–3 weeks of therapy.
• Gastrointestinal upset: Nausea, mild vomiting, and loss of appetite occur in up to 30 % of patients.
• Fatigue and alopecia: Generalized tiredness and diffuse hair thinning are reported by many individuals during treatment cycles.

Rare

• Dermatologic reactions: Rash, pruritus, or photosensitivity may develop, usually reversible upon discontinuation.
• Hepatotoxicity: Transient elevations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) have been documented in less than 5 % of patients.
• Peripheral neuropathy: Tingling or numbness in extremities is uncommon but warrants evaluation if it progresses.

Serious

• Severe bone‑marrow failure: Pancytopenia can lead to life‑threatening infections or bleeding; immediate hospitalization and supportive care are required.
• Secondary malignancies: Long‑term exposure carries a small but measurable risk of therapy‑related acute myeloid leukemia (AML) or myelodysplastic syndromes.
• Pulmonary toxicity: Interstitial pneumonitis and, rarely, pulmonary fibrosis have been reported and demand prompt discontinuation of the drug.

Drug–Drug Interactions

• Concomitant use of other myelosuppressive agents (e.g., cyclophosphamide, fludarabine) enhances bone‑marrow toxicity.
• Anticoagulants such as warfarin may have an amplified effect, increasing bleeding risk; INR should be monitored closely.
• Live vaccines are contraindicated while on Leukeran because of impaired immune response.
• Strong CYP2C9 inhibitors (e.g., fluconazole) can modestly raise chlorambucil plasma levels, potentially intensifying adverse effects.

Practical Use: Dosing, Missed Dose, Overdose

Standard dosing (adult, based on body surface area or weight) is typically:

• Induction schedule: .1–.2 mg/kg orally once daily for 7 consecutive days every 28 days.
• Continuous low‑dose regimen: .05–.1 mg/kg once daily without interruption, often used for long‑term disease control in CLL.

Dose adjustments are recommended for renal impairment (creatinine clearance < 30 mL/min) and for patients aged ≥ 75 years with borderline blood counts.

Missed dose: If a dose is forgotten, the patient should take it as soon as it is remembered, provided the next scheduled dose is at least 8 hours away. If the next dose is imminent, skip the missed tablet and continue with the regular schedule; do not double‑dose.

Overdose: Acute overdose may precipitate profound myelosuppression, gastrointestinal hemorrhage, or renal dysfunction. Management is primarily supportive: monitor complete blood counts every 12 hours, provide intravenous fluids, consider granulocyte‑colony stimulating factor (G‑CSF) for severe neutropenia, and treat any bleeding complications.

FAQ

• Is Leukeran available in both brand‑name and generic forms in Hong Kong?
  Yes. The brand‑name Leukeran is manufactured by Bristol‑Myers Squibb, while generic chlorambucil tablets are produced by several approved suppliers. Both contain the same active ingredient and meet the same regulatory standards.

• How should Leukeran be stored in Hong Kong’s humid climate?
  Leukeran tablets should be kept in a tightly closed container at room temperature (15‑30 °C), away from direct sunlight and moisture. A desiccant packet included in the packaging helps protect against humidity; do not store the medication in bathrooms or near kitchen sinks.

• What does a Leukeran tablet look like, and are there any inactive ingredients that could cause allergies?
  The tablets are typically round, film‑coated, and white to off‑white. Inactive components may include lactose, magnesium stearate, and microcrystalline cellulose. Patients with lactose intolerance or known hypersensitivity to these excipients should discuss alternatives with their healthcare provider.

• Can I travel with Leukeran on an international flight from Hong Kong?
  Yes, but keep the medication in its original packaging with the prescription label visible. Carry it in hand luggage to avoid temperature fluctuations in cargo holds, and be prepared to present a copy of the prescription or a doctor’s note if requested by airline security.

• Are there any special warnings for Asian populations taking Leukeran?
  Pharmacogenomic studies suggest that certain CYP2C9 variants, more prevalent in East Asian groups, may slightly modify chlorambucil metabolism. Nonetheless, dosing recommendations remain unchanged; clinicians simply monitor blood counts more closely during the initial treatment cycles.

• Does Leukeran interact with traditional Chinese herbal medicines?
  Some herbal preparations contain immunomodulatory or myelosuppressive constituents (e.g., astragalus, ginseng). Co‑administration could potentiate bone‑marrow suppression, so patients should disclose all complementary medicines to their treating physician.

• What are the key clinical trials that established Leukeran’s efficacy?
  Landmark Phase III trials in the 197s and 198s demonstrated superior overall response rates of chlorambucil versus chlorambucil plus prednisone in untreated CLL. More recent comparative studies have shown that low‑dose chlorambucil remains effective when combined with targeted agents such as ibrutinib, confirming its continued relevance.

• How does the safety profile of Leukeran compare with more aggressive intravenous regimens?
  Oral chlorambucil generally causes less acute toxicity (e.g., lower rates of severe nausea, alopecia, and infusion‑related reactions) than high‑dose alkylators like cyclophosphamide. However, long‑term risks such as secondary malignancies remain comparable and require regular monitoring.

• Is Leukeran subject to drug testing for employment or sports?
  Chlorambucil is not listed on the World Anti‑Doping Agency (WADA) prohibited list, but its presence can be detected in urine or blood assays. For occupational drug testing, laboratories may flag it as a therapeutic agent rather than a prohibited substance.

• What regulatory pathway allows personal import of Leukeran into Hong Kong?
  The Hong Kong Customs and Excise Department permits import of a 90‑day supply of prescription medicines for personal use, provided the patient possesses a valid prescription from a licensed practitioner and the medication is for personal consumption only.
