Matulane (procarbazine) is a prodrug that undergoes metabolic activation to generate cytotoxic alkylating metabolites. It inhibits DNA, RNA, and protein synthesis through methylation of nucleic acids and proteins, and may also inhibit monoamine oxidase.
CD20-directed cytolytic antibody; binds to CD20 antigen on B-lymphocytes, inducing antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis.
Treatment of advanced Hodgkin lymphoma (in combination with other drugs),Treatment of non-Hodgkin lymphoma (off-label),Treatment of brain tumors (off-label)
Relapsed or refractory follicular lymphoma (FL) after two or more lines of systemic therapy,Relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after two or more lines of systemic therapy
200-300 mg orally once daily for 10-14 days as part of MOPP regimen; maintenance dose: 50-100 mg orally once daily after hematologic recovery.
12 mg/kg intravenously on Day 1 of each 21-day cycle for 12 cycles in combination with bendamustine. For patients with relapsed or refractory follicular lymphoma after two or more prior therapies, the recommended dose is 12 mg/kg intravenously on Day 1 of each 28-day cycle until disease progression or unacceptable toxicity.
Terminal elimination half-life is approximately 7-10 hours (range 5-15 hours) in adults; context: prolonged in hepatic or renal impairment.
Terminal half-life approximately 20 days (range 14-28 days), consistent with Ig G1 monoclonal antibody clearance via intracellular catabolism.
Procarbazine is metabolized primarily by the liver via oxidation by CYP450 enzymes and other oxidases to active metabolites. It also undergoes some metabolism by monoamine oxidase (MAO) in the liver and other tissues.
Metabolized via non-specific proteolysis into small peptides and amino acids; not metabolized by CYP450 enzymes.
Primarily renal (approximately 50-60% as unchanged drug and metabolites) and fecal (approximately 10-20%); minor biliary excretion.
Primarily eliminated via biliary/fecal route; renal excretion is minimal (less than 1% of dose).
Approximately 10-20% bound to plasma proteins (mainly albumin); minimal binding.
No specific protein binding data; as a monoclonal antibody, it is not bound to plasma proteins in a significant manner.
Approximately 3-4 L/kg; indicates extensive tissue distribution including brain (penetrates CNS).
Approximately 4.5 L (0.06 L/kg assuming 70 kg), indicating limited extravascular distribution, primarily confined to plasma and interstitial space.
Oral bioavailability is nearly complete (close to 100%) after oral administration.
Intravenous administration yields 100% bioavailability.
GFR ≥50 m L/min: no adjustment; GFR 10-50 m L/min: reduce dose to 50-75%; GFR <10 m L/min: avoid use or reduce to 50% and monitor.
No dose adjustment recommended for mild to moderate renal impairment (Cr Cl ≥30 m L/min). Not studied in severe renal impairment (Cr Cl <30 m L/min) or on dialysis.
Child-Pugh A: 100% of dose; Child-Pugh B: reduce by 50%; Child-Pugh C: avoid use.
No dose adjustment recommended for mild hepatic impairment (Child-Pugh A). Not studied in moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment.
Based on BSA: 100 mg/m2 orally once daily for 14 days as part of MOPP; or 50 mg/m2 orally on days 1-14.
Safety and effectiveness in pediatric patients have not been established.
Start at lower end of dosing range (e.g., 200 mg daily) due to increased risk of myelosuppression and renal/hepatic impairment; monitor CBCs closely.
No specific dose adjustment recommended for elderly patients (≥65 years). Clinical studies included patients up to 88 years; no overall differences in safety or efficacy observed.
Procarbazine is carcinogenic, mutagenic, and teratogenic. It should be used only by physicians experienced in cancer chemotherapy. Patients receiving procarbazine should be carefully monitored for hematologic toxicity.
WARNING: CYTOKINE RELEASE SYNDROME (CRS). Serious or life-threatening CRS can occur, including infusion-related reactions. Premedicate and monitor during infusion. Withhold or permanently discontinue as recommended.
Bone marrow suppression (leukopenia, thrombocytopenia, anemia) requires dose adjustment; discontinue if toxicity is severe. CNS effects (drowsiness, depression, confusion) may occur. Disulfiram-like reaction with alcohol. Hypertensive crisis can occur with tyramine-rich foods or sympathomimetics due to MAO inhibition. Monitor for secondary malignancies. Fetal harm can occur; avoid pregnancy.
Cytokine release syndrome (CRS), including serious or life-threatening reactions,Neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS),Infections, including serious and opportunistic infections,Tumor flare reaction,Embryo-fetal toxicity
Hypersensitivity to procarbazine; concomitant use with MAO inhibitors, tricyclic antidepressants, or other drugs with MAO-inhibiting activity; severe bone marrow depression; pregnancy.
None known.
Avoid tyramine-rich foods: aged cheeses (cheddar, Swiss), cured meats (salami, pepperoni), fermented soy products (tofu, miso), sauerkraut, pickled herring, broad bean pods, yeast extracts, red wine, beer, and draft beers. Also avoid alcohol completely due to additive CNS depression.
Avoid grapefruit and grapefruit juice. No other specific food interactions reported. Maintain adequate hydration to prevent tumor lysis syndrome.
Matulane (procarbazine) is a known teratogen. First trimester exposure is associated with major congenital malformations. Second and third trimester exposure carries risk of intrauterine growth restriction, fetal bone marrow suppression, and potential carcinogenesis. Use contraindicated in pregnancy.
COLUMVI (glofitamab) is a CD3/CD20 bispecific antibody. Based on its mechanism of action and animal studies, there is a potential for fetal harm. Ig G molecules cross the placenta; fetal exposure increases as pregnancy progresses, with the largest amount transferred during the third trimester. Glofitamab may cause fetal B-cell depletion and immune dysfunction. There are no adequate human data. Contraindicated during pregnancy; advise effective contraception during treatment and for 3 months after the last dose.
Procarbazine is excreted into breast milk. M/P ratio not reported. Due to potential for carcinogenicity and adverse effects in the nursing infant, breastfeeding is contraindicated during matulane therapy and for at least 2 weeks after last dose.
No data on presence in human milk, effects on the breastfed child, or milk production. Human Ig G is secreted into breast milk, but minimal systemic absorption in the infant is expected. Because of potential for serious adverse reactions (including B-cell depletion), advise patients not to breastfeed during treatment and for at least 3 months after the last dose. M/P ratio: unknown.
No well-established safe dose in pregnancy. If therapy is deemed essential despite risks, significant dose reduction and increased monitoring advised. Pharmacokinetic changes in pregnancy may alter procarbazine metabolism, but specific dose adjustments are not defined. Use only in life-threatening conditions with expert consultation.
No clinical trials have evaluated dosing in pregnancy. Pharmacokinetics of therapeutic antibodies are not significantly altered by pregnancy-mediated changes; however, increased plasma volume and altered clearance may occur. No specific dose adjustments are recommended; if benefit outweighs risk, administer at standard dosing (2.5 mg and 10 mg step-up doses, then 30 mg fixed dose every 21 days for up to 12 cycles). Clinical judgment required due to lack of data; consider therapeutic drug monitoring if available.
Matulane (procarbazine) is a monoamine oxidase inhibitor (MAOI); concurrent use with sympathomimetics, tyramine-rich foods, or tricyclic antidepressants can precipitate hypertensive crisis. It is also a potent CNS depressant; avoid alcohol. Monitor for leukopenia and thrombocytopenia; nadir typically occurs 2-4 weeks after therapy. Discontinue if hypersensitivity pneumonitis occurs.
COLUMVI (glofitamab) is a CD3x CD20 bispecific antibody for relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Administer with prior rituximab and premedication to mitigate cytokine release syndrome (CRS). Monitor for CRS closely during step-up dosing; consider tocilizumab for management. Ensure adequate IV hydration and uric acid monitoring for tumor lysis syndrome. Do not coadminister with other systemic immunosuppressants unless necessary. Assess for hepatitis B reactivation prior to initiation.
