Antineoplastic Agents, Alkylating
National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)
CeeNU has been shown to be useful as a single agent in addition to other treatment modalities, or in established combination therapy with other approved chemotherapeutic agents in the following: Brain tumors-both primary and metastatic, in patients who have already received appropriate surgical and/or radiotherapeutic procedures. Hodgkin's Disease-secondary therapy in combination with other approved drugs in patients who relapse while being treated with primary therapy, or who fail to respond to primary therapy. /Included in US product label/

Antineoplastic agent. The compound has had limited use since the early 1970s in the treatment of Hodgkin's disease and various solid tumors. These include primary and metastatic brain tumors, colorectal tumors, and certain pulmonary malignancies. It is usually used in conjunction with other antineoplastic drugs.

Although lomustine is labeled for use in combination with other agents as secondary therapy for the treatment of refractory or relapsed Hodgkin's disease, combination regimens containing other agents currently are preferred for this cancer. /Included in US product label/

/BOXED WARNING/ WARNINGS: CeeNU (lomustine) should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to bleeding and overwhelming infections in an already compromised patient, is the most common and severe of the toxic effects of CeeNU. Since the major toxicity is delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose. At the recommended dosage, courses of CeeNU should not be given more frequently than every 6 weeks. The bone marrow toxicity of CeeNU is cumulative and therefore dosage adjustment must be considered on the basis of nadir blood counts from prior dose

Because some lomustine metabolites are present in milk, women receiving the drug probably should not nurse their infants.

Delayed onset of pulmonary fibrosis occurring up to 17 years after treatment has been reported in patients receiving related nitrosoureas combined with cranial radiation therapy for intracranial tumors during childhood and adolescence (age 1-16 years). Late onset of reduction in pulmonary function was observed in all long-term survivors. Nitrosourea-induced pulmonary fibrosis may be slowly progressive and can cause death.
American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 1153
Nausea and vomiting occur in 45-100% of patients within 45 min to 6 hr after ingestion of an oral dose of lomustine. Although these symptoms are not severe and usually abate within 24 hr, they may persist up to 36 hr and are often followed by 2-3 days of anorexia. Stomatitis has occurred infrequently.

For the treatment of primary and metastatic brain tumors as a component of combination chemotherapy in addition to appropriate surgical and/or radiotherapeutic procedures. Also used in combination with other agents as secondary therapy for the treatment of refractory or relapsed Hodgkin's disease.
Lomustine is an alkylating agent of the nitrosourea type. Lomustine and its metabolites interferes with the function of DNA and RNA. It is cell cycle–phase nonspecific. Cancers form when some cells within the body multiply uncontrollably and abnormally. These cells then spread and destroy nearby tissues. Lomustine acts by slowing this process down. It kills cancer cells by damaging the DNA (the genetic material inside the cells) and stops them from dividing.
Antineoplastic Agents, Alkylating
A class of drugs that differs from other alkylating agents used clinically in that they are monofunctional and thus unable to cross-link cellular macromolecules. Among their common properties are a requirement for metabolic activation to intermediates with antitumor efficacy and the presence in their chemical structures of N-methyl groups, that after metabolism, can covalently modify cellular DNA. The precise mechanisms by which each of these drugs acts to kill tumor cells are not completely understood. (From AMA, Drug Evaluations Annual, 1994, p2026) (See all compounds classified as Antineoplastic Agents, Alkylating.)

Absorption
Well and rapidly absorbed from the gastrointestinal tract.
Route of Elimination
Following oral administration of radioactive CeeNU at doses ranging from 30 mg/m2 to 100 mg/m2, about half of the radioactivity given was excreted in the urine in the form of degradation products within 24 hours.
Lomustine is excreted primarily in the urine as metabolites. Following oral administration of (14)C-labeled lomustine, about 50% of the radioactivity is excreted within 12 hr and about 75% within 4 days.
American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 1154
Lomustine is reported to be widely distributed. Lomustine and/or its metabolites cross the blood-brain barrier and are rapidly transported into cells due to their high lipid solubility. Although intact lomustine is not detectable in the CSF, active metabolites of the drug appear in substantial concentrations within 30 minutes after oral administration of lomustine. CSF concentrations of metabolites have been reported to be 15-50% or greater than concurrent plasma concentrations. Lomustine metabolites are present in milk, but in concentrations than those in maternal plasma.
American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 1154
Lomustine is rapidly absorbed from the GI tract; the drug is also absorbed following topical application. Peak plasma concentrations of metabolites occur within 1-6 hours following administration of an oral dose of lomustine.

Following its ip or iv injection or oral administration, (14)C-labelled CCNU was rapidly distributed to many tissues in mice, rats, rabbits and dogs.. About 80% of label was excreted in the urine of mice 24 hours after a single parenteral or oral dose of 50 mg/kg bw.

Hepatic. Rapid and complete, with active metabolites.
CCNU undergoes spontaneous decomposition under physiological conditions to release both alkylating and carbamoylating entities. It disappears from plasma within 5 minutes following its oral administration, but the antitumor effect of its metabolites may persist for up to 15 minutes. ... In addition to chemical decomposition, CCNU may be converted by microsomal metabolism to 6 isomeric hydroxylated derivatives, some of which may differ in their biological properties from CCNU.

Virtually all of a dose of lomustine is metabolized within 1 hour after oral administration. The half-life of lomustine metabolites is biphasic; although the initial plasma half-life is 6 hours, the second phase plasma half-life is 1-2 days, and 15-20% of the metabolites remain in the body 5 days after administration of lomustine. Prolongation of plasma concentrations is thought to reflect a combination of protein binding and enterohepatic circulation of metabolites.

Approximately 94 minutes, however the metabolites have a serum half-life of 16 to 48 hours.

Lomustine is a highly lipophilic nitrosourea compound which undergoes hydrolysis in vivo to form reactive metabolites. These metabolites cause alkylation and cross-linking of DNA (at the O6 position of guanine-containing bases) and RNA, thus inducing cytotoxicity. Other biologic effects include inhibition of DNA synthesis and some cell cycle phase specificity. Nitrosureas generally lack cross-resistance with other alkylating agents. As lomustine is a nitrosurea, it may also inhibit several key processes such as carbamoylation and modification of cellular proteins.
Although lomustine is believed to act by alkylation, the mechanism of action has not been completely elucidated, and other effects as carbamoylation and modification of cellular proteins may be involved. The overall result is thought to be the inhibition of both DNA and RNA synthesis.
