  • Hematologic Toxicity: Granulocytopenia, anemia, thrombocytopenia, and pancytopenia have been reported in patients treated with Ganciclovir [see Warnings and Precautions (5.1)].
  • Impairment of Fertility: Based on animal data, Ganciclovir INJECTION may cause temporary or permanent inhibition of spermatogenesis in males and suppression of fertility in females [see Warnings and Precautions (5.3)].
  • Fetal Toxicity: Based on animal data, Ganciclovir INJECTION has the potential to cause birth defects in humans [see Warnings and Precautions (5.4)].
  • Mutagenesis and Carcinogenesis: Based on animal data, Ganciclovir INJECTION has the potential to cause cancer in humans [see Warnings and Precautions (5.5)].

Indications and Usage for Ganciclovir

Treatment of CMV Retinitis

Ganciclovir INJECTION is indicated for the treatment of cytomegalovirus (CMV) retinitis in immunocompromised adult patients, including patients with acquired immunodeficiency syndrome (AIDS) [see Clinical Studies (14)]

Prevention of CMV Disease in Transplant Recipients

Ganciclovir INJECTION is indicated for the prevention of CMV disease in adult transplant recipients at risk for CMV disease [see Clinical Studies (14)].

Ganciclovir Dosage and Administration

Important Dosing and Administration Information

  • Do not administer Ganciclovir INJECTION by rapid or bolus intravenous injection which may increase toxicity as a result of excessive plasma levels.
  • The recommended dosage and infusion rate for Ganciclovir INJECTION should not be exceeded.
  • Administration of Ganciclovir INJECTION should be accompanied by adequate hydration.
  • Ganciclovir INJECTION should only be infused into veins with adequate blood flow to permit rapid dilution and distribution.
  • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Testing Before and During Treatment

  • Females of reproductive potential should undergo pregnancy testing before initiation of Ganciclovir INJECTION [see Warnings and Precautions (5.4), Use in Specific Populations (8.1, 8.3)].
  • Complete blood counts with differential and platelet counts should be performed frequently, especially in patients in whom Ganciclovir or other nucleoside analogues have previously resulted in cytopenias, or in whom absolute neutrophil counts are less than 1000 cells/μL at the beginning of treatment [see Warnings and Precautions (5.1)].
  • All patients should be monitored for renal function before and during treatment with Ganciclovir INJECTION and dosage should be adjusted as needed [see Dosage and Administration (2.5), Warnings and Precautions (5.2)].

Patients with CMV retinitis should have frequent ophthalmological examinations during treatment with Ganciclovir INJECTION to monitor disease status and for other retinal abnormalities [see Adverse Reactions (6.1)].

Recommended Dosage for Treatment of CMV Retinitis in Adult Patients with Normal Renal Function

Induction Dosage: The recommended initial dosage of Ganciclovir INJECTION for patients with normal renal function is 5 mg/kg (given intravenously at a constant rate over 1 hour) every 12 hours for 14 to 21 days.

Maintenance Dosage: Following induction treatment, the recommended maintenance dosage of Ganciclovir INJECTION is 5 mg/kg (given intravenously at a constant rate over 1 hour) once daily for 7 days per week, or 6 mg/kg once daily for 5 days per week.

Recommended Dosage for Prevention of CMV Disease in Adult Transplant Recipients with Normal Renal Function

Induction Dosage:The recommended initial dosage of Ganciclovir INJECTION for patients with normal renal function is 5 mg/kg (given intravenously at a constant rate over 1 hour) every 12 hours for 7 to 14 days.

Maintenance Dosage: Following induction, the recommended maintenance dosage of Ganciclovir INJECTIONS is 5 mg/kg (given intravenously at a constant rate over 1 hour) once daily for 7 days per week, or 6 mg/kg once daily for 5 days per week until 100 to 120 days post-transplantation.

Recommended Dosage in Adult Patients with Renal Impairment

For patients with renal impairment, refer to Table 1 for recommended doses of Ganciclovir INJECTION for induction and maintenance dosage for treatment of CMV retinitis and prevention of CMV disease in transplant patients. Monitor serum creatinine or creatinine clearance during treatment to allow for dosage adjustments in patients with impaired renal function.

Dosing for patients undergoing hemodialysis should not exceed 1.25 mg per kg 3 times per week,

following each hemodialysis session. Ganciclovir INJECTION should be given shortly after completion of the hemodialysis session, since hemodialysis has been shown to reduce plasma levels by approximately 50% [see Clinical Pharmacology (12.3)].

Handling and Disposal

Because Ganciclovir shares some of the properties of antitumor agents (i.e., carcinogenicity and mutagenicity), procedures for proper handling and disposal for cytotoxic drugs should be considered1[see How Supplied/Storage and Handling (16)]. The premix flexible plastic container bag contains no preservative; therefore, any unused portion should be discarded after each use. 

Dosage Forms and Strengths

Injection:  500 mg of Ganciclovir in 250 mL (2 mg per mL) sterile, unpreserved, colorless solution in a single-dose bag for intravenous use. 

Contraindications

Ganciclovir INJECTION is contraindicated in patients who have experienced a clinically significant hypersensitivity reaction (e.g., anaphylaxis) to Ganciclovir, valGanciclovir or acyclovir.

Warnings and Precautions

Hematologic Toxicity

Granulocytopenia (neutropenia), anemia,thrombocytopenia, and pancytopenia have been observed in patients treated with Ganciclovir. The frequency andseverity of these events vary widely in different patient populations [see Adverse Reactions (6.1)].Ganciclovir INJECTION is not recommended if the absolute neutrophil count is less than 500 cells/μL, hemoglobin is less than 8 g/dL, or the platelet count is less than 25,000 cells/μL. Ganciclovir INJECTION should also be used with caution in patients with pre-existing cytopenias and in patients receiving myelosuppressive drugs or irradiation. Neutropenia usually occurs during the first or second week of treatment but may occur at any time during treatment. Cell counts usually begin to recover within 3 to 7 days after discontinuing drug. Colony-stimulating factors have been shown to increase neutrophil and white blood cell counts in patients receiving Ganciclovir for treatment of CMV retinitis.

Due to the frequency of neutropenia, anemia and thrombocytopenia in patients receiving Ganciclovir INJECTION, complete blood counts with differential and platelet counts should be performed frequently, especially in patients in whom Ganciclovir or other nucleoside analogues have previously resulted in leukopenia, or in whom neutrophil counts are less than 1000 cells/µL at the beginning of treatment [see Dosage and Administration (2.2)].

Impairment of Renal Function

Increased serum creatinine levels have been reported in elderly patients and in transplant patients receiving concomitant nephrotoxic medications (i.e., cyclosporine and amphotericin B).  Monitoring renal function during therapy with Ganciclovir INJECTION is essential, especially for elderly patients and those patients receiving concomitant agents that may cause nephrotoxicity [see Dosage and Administration (2.5), Use in Specific Populations (8.5)].

Impairment of Fertility

Based on animal data, Ganciclovir INJECTION at the recommended human dose (RHD) may cause temporary or permanent inhibition of spermatogenesis in males, and may cause suppression of fertility in females. Advise patients that fertility may be impaired with use of Ganciclovir INJECTION [see Use in Specific Population (8.1), Nonclinical Toxicology (13.1)].

Fetal Toxicity

Ganciclovir INJECTION may cause fetal toxicity when administered to pregnant women based on findings in animal studies.  Systemic exposure of Ganciclovir in animals at approximately 2 times the RHD caused fetal growth retardation, embryolethality, teratogenicity, and/or maternal toxicity. Teratogenic changes in animals included cleft palate, anophthalmia/microphthalmia, aplastic organs (kidney and pancreas), hydrocephaly and brachygnathia.  Women of childbearing potential should be advised to use effective contraception during treatment and for at least 30 days following treatment with Ganciclovir INJECTION. Similarly, men should be advised to practice barrier contraception during and for at least 90 days following treatment with Ganciclovir INJECTION [see Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)].

Mutagenesis and Carcinogenesis

Animal data indicate that Ganciclovir is mutagenic and carcinogenic. Ganciclovir INJECTION should therefore be considered a potential carcinogen in humans [see Dosage and Administration (2.6), Nonclinical Toxicology (13.1)].

Adverse Reactions

The following adverse reactions are discussed in other sections of the labeling:

  • Hematologic Toxicity [see Warnings and Precautions (5.1)]
  • Impairment of Renal Function [see Warnings and Precautions (5.2)]
  • Impairment of Fertility [see Warnings and Precautions (5.3)]
  • Fetal Toxicity [see Warnings and Precautions (5.4)]
  • Mutagenesis and Carcinogenesis [see Warnings and Precautions (5.5)]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse Reactions in Patients with CMV Retinitis
Three controlled, randomized, phase 3 trials comparing intravenous Ganciclovir and Ganciclovir capsules for maintenance treatment of CMV retinitis have been completed. During these trials, 9% of subjects were prematurely discontinued because of adverse reactions. Selected adverse reactions and laboratory abnormalities reported during the conduct of these controlled trials are summarized in Table 2 and Table 3, respectively [see Clinical Studies (14)].

USE IN SPECIFIC POPULATIONS

Pregnancy

Risk Summary
Inanimal studies, Ganciclovir caused maternal and fetal toxicity and embryo-fetal mortality in pregnant mice and rabbits as well as teratogenicity in rabbits at exposures two times the exposure at the recommended human dose (RHD)
[see Data]. Although placental transfer of Ganciclovir has been shown to occur based on ex vivo experiments with human placenta and on at least one case report in a pregnant woman, no adequate human data are available to establish whether Ganciclovir INJECTION poses a risk to pregnancy outcomes. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in the clinically recognized pregnancies is 2-4% and 15−20%, respectively.

Clinical considerations

Disease-associated maternal and/or fetal risk

Most maternal CMV infections are subclinical or they may be associated with a mononucleosis-like syndrome.  However, in immunocompromised patients, CMV infections are often symptomatic and are associated with significant morbidity and mortality. The transmission of CMV to the fetus is a result of maternal viremia and transplacental infection. CMV infection can also occur perinatally from mother to infant by exposure to CMV in cervicovaginal secretions. Approximately 10% of infected newborns are symptomatic at birth. Mortality in symptomatic infants is about 10%, and approximately 50 to 90% of survivors experience significant problems, including sensorineural hearing loss, mental retardation, and other neurologic deficits. The risk and severity of congenital CMV infection appear to be higher in infants born to mothers with primary CMV infection than in those born to mothers with reactivation of CMV infection.

Data

Animal Data

Daily intravenous doses of Ganciclovir were administered to pregnant mice (108 mg/kg/day) and rabbits (60 mg/kg/day), and also to female mice (90 mg/kg) prior to mating, during gestation, and during lactation.  Fetal resorptions were present in at least 85% of rabbits and mice. Additional effects observed in rabbits included fetal growth retardation, embryolethality, teratogenicity, and/or maternal toxicity. Teratogenic changes included cleft palate, anophthalmia/microphthalmia, aplastic organs (kidney and pancreas), hydrocephaly and brachygnathia. In pre/postnatal development studies in mice, there were maternal/fetal toxicity and embryolethality which included fetal effects of hypoplasia of the testes and seminal vesicles in the male offspring, as well as pathologic changes in the nonglandular region of the stomach. The systemic exposure (AUC) of Ganciclovir during these studies was approximately 2-times (pregnant mice and rabbits) and 1.7-times (pre/postnatal mice) the exposure in humans at the RHD [see Nonclinical Toxicology (13.1)].

Lactation

Risk Summary
No data are available regarding the presence of Ganciclovir in human milk, the effects on the breastfed infant, or the effects on milk production. When Ganciclovir was administered to lactating rats, Ganciclovir was present in milk
[see Data]. Advise nursing mothers that breastfeeding is not recommended during treatment with Ganciclovir INJECTION because of the potential for serious adverse reactions in nursing infants. Furthermore, the Centers for Disease Control and Prevention recommends that HIV-infected mothers not breastfeed their infants to avoid potential postnatal transmission of HIV [see Warnings and Precautions (5.1, 5.3, 5.5), Nonclinical Toxicology (13.1)].

Data

Animal Data

Ganciclovir administered intravenously (at 0.13 mg/h) to lactating rats (on lactation day 15) resulted in passive transfer into milk.  The milk-to-serum ratio for Ganciclovir at steady state was 1.6 ± 0.33.

Females and Males of Reproductive Potential

Pregnancy Testing
Females of reproductive potential should undergo pregnancy testing before initiation of Ganciclovir INJECTION
[see Dosage and Administration (2.2), Use in Specific Populations (8.1)].

Contraception

Females

Because of the mutagenic and teratogenic potential of Ganciclovir, females of reproductive potential should be advised to use effective contraception during treatment and for at least 30 days following treatment with Ganciclovir INJECTION [see Warnings and Precautions (5.3, 5.4), Nonclinical Toxicology (13.1)].

Males

Because of its mutagenic potential, males should be advised to practice barrier contraception during and for at least 90 days following, treatment with Ganciclovir INJECTION [see Warnings and Precautions (5.3, 5.4), Nonclinical Toxicology (13.1)].

Infertility
Ganciclovir INJECTION at the recommended doses may cause temporary or permanent female and male infertility
[see Warnings and Precautions (5.3, 5.4), Nonclinical Toxicology (13.1)].

Pediatric Use

Safety and efficacy of Ganciclovir INJECTION have not been established in pediatric patients.

A total of 120 pediatric patients with serious CMV infections participated in clinical trials. Granulocytopenia and thrombocytopenia were the most common adverse reactions.

The pharmacokinetic characteristics of Ganciclovir administered intravenously were studied in 27 neonates (aged 2 to 49 days) and 10 pediatric patients, aged 9 months to 12 years. In neonates,  the pharmacokinetic parameters after Ganciclovir intravenous doses of 4 mg/kg (n=14) and 6 mg/kg (n=13) were Cmax 5.5 ± 1.6 and 7.0 ± 1.6 μg/mL, systemic clearance 3.14 ± 1.75 and 3.56 ± 1.27 mL/min/kg, and t1/2 of 2.4  hours (harmonic mean) for both doses, respectively.

In pediatric patients 9 months to 12 years of age, the pharmacokinetic characteristics of Ganciclovir were the same after single and multiple (every 12 hours) intravenous doses (5 mg/kg). The steady-state volume of distribution was 0.64 ± 0.22 L/kg, Cmax was 7.9 ± 3.9 μg/mL, systemic clearance was 4.7 ± 2.2 mL/min/kg, and t1/2 was 2.4 ± 0.7 hours.

Although the pharmacokinetics of intravenous Ganciclovir in pediatric patients were similar to those observed in adults, the safety and efficacy of Ganciclovir at these exposures in pediatric patients have not  been established.

Geriatric Use

Clinical studies of Ganciclovir did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Ganciclovir is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection. In addition, renal function should be monitored and dosage adjustments should be made accordingly [see Dosage and Administration (2.5), Warnings and Precautions (5.2), Use in Specific Populations (8.6)].

Renal Impairment

Dose reduction is recommended when administering Ganciclovir INJECTION to patients with renal impairment [see Dosage and Administration (2.5), Warnings and Precautions (5.2), Adverse Reactions (6.1)].

Hemodialysis has been shown to reduce plasma levels of Ganciclovir by approximately 50%.

Hepatic Impairment

The safety and efficacy of Ganciclovir have not been studied in patients with hepatic impairment.

Overdosage

Adverse reactions reported with overdosage of intravenous Ganciclovir included irreversible pancytopenia, acute renal failure requiring hemodialysis, neutropenia, thrombocytopenia, hepatitis, and seizures.

Since Ganciclovir is dialyzable, dialysis may be useful in reducing serum concentrations. Adequate hydration should be maintained. The use of hematopoietic growth factors should be considered in patients with cytopenias [see Dosage and Administration (2.5), Warnings and Precautions (5.1)].

Ganciclovir - Clinical Pharmacology

Mechanism of Action

Ganciclovir is an antiviral drug with activity against cytomegalovirus (CMV) [see Microbiology (12.4)].

Pharmacokinetics

Absorption:
At the end of a 1-hour intravenous infusion of 5 mg/kg Ganciclovir, total AUC ranged between 22.1 ±3.2 (n=16) and 26.8 ± 6.1 g·hr/mL (n=16) and Cmax ranged between 8.27 ± 1.02 (n=16) and 9.0 ± 1.4 g/mL (n=16).

Distribution:
The steady-state volume of distribution of Ganciclovir after intravenous administration was 0.74 ± 0.15 L/kg (n=98). Cerebrospinal fluid concentrations obtained 0.25 to 5.67 hours post-dose in 3 patients who received 2.5 mg/kg Ganciclovir intravenously every 8 hours or every 12 hours ranged from 0.31 to 0.68 g/mL representing 24% to 70% of the respective plasma concentrations. Binding to plasma proteins was 1% to 2% over Ganciclovir concentrations of 0.5 and 51 g/mL.

Elimination:
Renal excretion of unchanged drug by glomerular filtration and active tubular secretion is the major route of elimination of Ganciclovir. In patients with normal renal function, 91.3 ± 5.0% (n=4) of intravenously administered Ganciclovir was recovered unchanged in the urine. Systemic clearance of intravenously administered Ganciclovir was 3.52 ± 0.80 mL/min/kg (n=98) while renal clearance was 3.20 ± 0.80 mL/min/kg (n=47), accounting for 91 ± 11% of the systemic clearance (n=47). Following intravenous administration, Ganciclovir half-life was 3.5 ± 0.9 hours (n=98) with linear pharmacokinetics over the dose range of 1.6 to 5.0 mg/kg.

Specific Populations

Patients with Renal Impairment

The pharmacokinetics of Ganciclovir following intravenous administration of Ganciclovir were evaluated in 10 immunocompromised patients with renal impairment who received doses ranging from 1.25 to 5.0 mg/kg (Table 7). Hemodialysis reduces plasma concentrations of Ganciclovir by about 50% after intravenous administration.

Race (Ethnicity) and Gender
The effects of race/ethnicity and gender were studied in subjects receiving a dose regimen of 1000 mg every 8 hours. Although the numbers of Blacks (16%) and Hispanics (20%) were small, there appeared to be a trend towards a lower steady-state C
max and AUC0-8 in these subpopulations as compared to Caucasians. No definitive conclusions regarding gender differences could be made because of the small number of females (12%); however, no differences between males and females were observed.

When the standard intravenous Ganciclovir induction dose (5 mg/kg infused over 1 hour every 12 hours) was coadministered with didanosine at a dose of 200 mg orally every 12 hours, the steady-state didanosine AUC0-12 increased 70 ± 40% (range: 3% to 121%, n=11) and Cmax increased 49 ± 48% (range: -28% to 125%). In a separate study, when the standard intravenous Ganciclovir maintenance dose (5 mg/kg infused over 1 hour every 24 hours) was coadministered with didanosine at a dose of 200 mg orally every 12 hours, didanosine AUC0-12 increased 50 ± 26% (range: 22% to 110%, n=11) and Cmax increased 36 ± 36% (range: -27% to 94%) over the first didanosine dosing interval. Ganciclovir pharmacokinetics were not affected by didanosine. In both studies, there was no significant change in the renal clearance of either drug.

Zidovudine

At an oral dose of 1000 mg of Ganciclovir every 8 hours, mean steady-state Ganciclovir AUC0-8

decreased 17 ± 25% (range: -52% to 23%) in the presence of zidovudine, 100 mg every 4 hours (n=12). Steady-state zidovudine AUC0-4 increased 19 ± 27% (range: -11% to 74%) in the presence of Ganciclovir. No drug-drug interaction studies have been conducted with intravenous Ganciclovir and zidovudine.

Probenecid

At an oral dose of 1000 mg of Ganciclovir every 8 hours (n=10), Ganciclovir AUC0-8 increased 53 ± 91% (range: -14% to 299%) in the presence of probenecid, 500 mg every 6 hours. Renal clearance of Ganciclovir decreased 22 ± 20% (range: -54% to -4%), which is consistent with an interaction involving competition for renal tubular secretion. No drug-drug interaction studies have been conducted with intravenous Ganciclovir and probenecid.

Cyclosporine

In a retrospective analysis of 93 liver allograft recipients receiving Ganciclovir (5 mg/kg infused over 1 hour every 12 hours) and oral cyclosporine (at therapeutic doses), there was no evidence of an effect on cyclosporine whole blood concentrations.

Microbiology

Antiviral Activity
Thciclovir is a synthetic analogue of 2'-deoxyguanosine, which inhibits replication of human CMV in cell culture and
in vivo. In CMV-infected cells, Ganciclovir is initially phosphorylated to Ganciclovir monophosphate by the viral protein kinase, pUL97. Further phosphorylation occurs by cellular kinases to produce Ganciclovir triphosphate, which is then slowly metabolized intracellularly. As the phosphorylation is largely dependent on the viral kinase, phosphorylation of Ganciclovir occurs preferentially in virus-infected cells. The virustatic activity of Ganciclovir is due to inhibition of the viral DNA polymerase, pUL54, by Ganciclovir triphosphate.

Antiviral Activity
The median concentration of Ganciclovir that inhibits CMV replication (EC
50 value) in cell culture (laboratory strains or clinical isolates) has ranged from 0.08 to 13.6 micromolar (0.02 to 3.48 μg/mL). Ganciclovir inhibits mammalian cell proliferation (CC50 value) in cell culture at higher concentrations ranging from 118 to 2840 micromolar (30 to 725 μg/mL). Bone marrow-derived colony-forming cells are more sensitive [CC50 value = 0.1 to 2.7 micromolar (0.028 to 0.7 μg/mL)]. The relationship between the antiviral activity in cell culture and clinical response has not been established.

Resistance
Cell Culture: CMV isolates with reduced susceptibility to Ganciclovir have been selected in cell culture. Growth of CMV strains in the presence of Ganciclovir resulted in the selection of amino acid substitutions in the viral protein kinase pUL97 and the viral DNA polymerase pUL54.

In vivo: Viruses resistant to Ganciclovir can arise after prolonged treatment or prophylaxis with Ganciclovir by selection of substitutions in pUL97 and/or pUL54. Limited clinical data are available on the development of clinical resistance to Ganciclovir and many pathways to resistance exist. The possibility of viral resistance should be considered in patients who show poor clinical response or experience persistent viral excretion during therapy.

CMV resistance to Ganciclovir has been observed in individuals with AIDS and CMV retinitis who have never received Ganciclovir therapy. Viral resistance has also been observed in patients receiving prolonged treatment for CMV retinitis with Ganciclovir. In a controlled study of oral Ganciclovir for prevention of AIDS-associated CMV disease, 364 individuals had one or more cultures performed after at least 90 days of Ganciclovir treatment. Of these, 113 had at least one positive culture. The last available isolate from each subject was tested for reduced sensitivity, and 2 of 40 were found to be resistant to Ganciclovir. These resistant isolates were associated with subsequent treatment failure for retinitis. 

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis, Mutagenesis
Ganciclovir was carcinogenic in mice at the same mean drug exposure in humans as at the RHD (5 mg/kg). At the dose of 1000 mg/kg/day (1.4 times the exposure at the RHD) there was a significant increase in the incidence of tumors of the preputial gland in males, forestomach (nonglandular mucosa) in males and females, and reproductive tissues (ovaries, uterus, mammary gland, clitoral gland and vagina) and liver in females. At the dose of 20 mg/kg/day (0.1 times the exposure at the RHD), a slightly increased incidence of tumors was noted in the preputial and harderian glands in males, forestomach in males and females, and liver in females. No carcinogenic effect was observed in mice administered Ganciclovir at 1 mg/kg/day (exposure estimated as 0.01 times the RHD).  Except for histiocytic sarcoma of the liver, Ganciclovir-induced tumors were generally of epithelial or vascular origin. Although the preputial and clitoral glands, forestomach and harderian glands of mice do not have human counterparts, Ganciclovir should be considered a potential carcinogen in humans.

Ganciclovir increased mutations in mouse lymphoma cells and DNA damage in human lymphocytes in vitro at concentrations of 50 to 500 and 250 to 2000 μg/mL, respectively. In the mouse micronucleus assay, Ganciclovir was clastogenic at doses of 150 and 500 mg/kg (2.8 to 10 times the exposure at the RHD) but not at doses of 50 mg/kg (exposure approximately comparable to the RHD). Ganciclovir was not mutagenic in the Ames Salmonella assay at concentrations of 500 to 5000 μg/mL.

Impairment of Fertility
Ganciclovir caused decreased mating behavior, decreased fertility, and an increased incidence of embryolethality in female mice following doses of 90 mg/kg/day (exposures approximately 1.7 times the RHD). Ganciclovir caused decreased fertility in male mice and hypospermatogenesis in mice and dogs following daily oral or intravenous administration of doses ranging from 0.2 to 10 mg/kg. Systemic drug exposure (AUC) at the lowest dose showing toxicity in each species ranged from 0.03 to 0.1 times the exposure at the RHD.

Clinical Studies

Treatment of CMV Retinitis

In a retrospective, non-randomized, single-center analysis of 41 patients with AIDS and CMV retinitis diagnosed by ophthalmologic examination between August 1983 and April 1988, treatment with intravenous Ganciclovir resulted in a delay in mean (median) time to first retinitis progression compared to untreated controls [105 (71) days from diagnosis vs. 35 (29) days from diagnosis]. Patients in this series received induction treatment of intravenous Ganciclovir 5 mg/kg twice daily for 14 to 21 days followed by maintenance treatment with either 5 mg/kg once daily, 7 days per week or 6 mg/kg once daily, 5 days per week.

In a controlled, randomized trial conducted between February 1989 and December 1990, immediate treatment with intravenous Ganciclovir was compared to delayed treatment in 42 patients with AIDS and peripheral CMV retinitis; 35 of 42 patients (13 in the immediate-treatment group and 22 in the delayed-treatment group) were included in the analysis of time to retinitis progression. Based on masked assessment of fundus photographs, the mean [95% CI] and median [95% CI] times to progression of retinitis were 66 days [39, 94] and 50 days [40, 84], respectively, in the immediate-treatment group compared to 19 days [11, 27] and 13.5 days [8, 18], respectively, in the delayed-treatment group.

Data from trials ICM 1653, ICM 1774, and AVI034, which were performed comparing intravenous to oral Ganciclovir for treatment of CMV retinitis in patients with AIDS, are shown in Table 8, and Figures 1, 2, and 3, and are discussed below.

Trial ICM 1653

In this randomized, open-label, parallel group trial,  conducted between March 1991 and November1992, patients with AIDS and newly diagnosed CMV retinitis received a 3-week induction course of intravenous Ganciclovir, 5 mg/kg twice daily for 14 days followed by 5 mg/kg once daily for 1 additional week. Following the 21-day intravenous induction course, patients with stable CMV retinitis were randomized to receive 20 weeks of maintenance treatment with either intravenous Ganciclovir, 5 mg/kg once daily, or Ganciclovir capsules, 500 mg 6 times daily (3000 mg/day). The study showed that the mean [95% CI] and median [95% CI] times to progression of CMV retinitis, as assessed by masked reading of fundus photographs, were 57 days [44, 70] and 29 days [28, 43], respectively, for patients on oral therapy compared to 62 days [50, 73] and 49 days [29, 61], respectively, for patients on intravenous therapy. The difference [95% CI] in the mean time to progression between the oral and intravenous therapies (oral - IV) was -5 days [-22, 12]. See Figure 1 for comparison of the proportion of patients remaining free of progression over time.

Trial ICM 1774

In this three-arm, randomized, open-label, parallel group trial, conducted between June 1991 and August 1993, patients with AIDS and stable CMV retinitis following from 4 weeks to 4 months of treatment with intravenous Ganciclovir were randomized to receive maintenance treatment with intravenous Ganciclovir, 5 mg/kg once daily, Ganciclovir capsules, 500 mg 6 times daily, or Ganciclovir capsules, 1000 mg three times daily for 20 weeks. The study showed that the mean [95% CI] and median [95% CI] times to progression of CMV retinitis, as assessed by masked reading of fundus photographs, were 54 days [48, 60] and 42 days [31, 54], respectively, for patients on oral therapy compared to 66 days [56, 76] and 54 days [41, 69], respectively, for patients on intravenous therapy. The difference [95% CI] in the mean time to progression between the oral and intravenous therapies (oral - IV) was -12 days [-24, 0]. See Figure 2 for comparison of the proportion of patients remaining free of progression over time.

Trial AVI 034

In this randomized, open-label, parallel group trial, conducted between June 1991 and February 1993, patients with AIDS and newly diagnosed (81%) or previously treated (19%) CMV retinitis who had tolerated 10 to 21 days of induction treatment with intravenous Ganciclovir, 5 mg/kg twice daily, were randomized to receive 20 weeks of maintenance treatment with either Ganciclovir capsules, 500 mg 6 times daily or intravenous Ganciclovir, 5 mg/kg/day. The mean [95% CI] and median [95% CI] times to progression of CMV retinitis, as assessed by masked reading of fundus photographs, were 51 days [44, 57] and 41 days [31, 45], respectively, for patients on oral therapy compared to 62 days [52, 72] and 60 days [42, 83], respectively, for patients on intravenous therapy. The difference [95% CI] in the mean time to progression between the oral and intravenous therapies (oral - IV) was -11 days [-24, 1]. See Figure 3 for comparison of the proportion of patients remaining free of progression over time.

Comparison of other CMV retinitis outcomes between oral and intravenous formulations (development of bilateral retinitis, progression into Zone 1, and deterioration of visual acuity), while not definitive, showed no marked differences between treatment groups in these studies. Because of low event rates among these endpoints, these studies are underpowered to rule out significant differences in these endpoints.

Prevention of CMV Disease in Transplant Recipients

Intravenous Ganciclovir was evaluated in three randomized, controlled trials of prevention of CMV disease in organ transplant recipients.

Trial ICM 1496 

In a randomized, double-blind, placebo-controlled study of 149 heart transplant recipients at risk for CMV infection (CMV seropositive or a seronegative recipient of an organ from a CMV seropositive donor), there was a reduction in the overall incidence of CMV disease in patients treated with intravenous Ganciclovir. Immediately post-transplant, patients received intravenous Ganciclovir 5 mg/kg twice daily for 14 days followed by 6 mg/kg once daily for 5 days/week for an additional 14 days. Twelve of the 76 (16%) patients treated with intravenous Ganciclovir vs. 31 of the 73 (43%) placebo-treated patients developed CMV disease during the 120-day post-transplant observation period. No significant differences in hematologic toxicities were seen between the two treatment groups [see Adverse Reactions (6.1)].

Trial ICM 1689

In a randomized, double-blind, placebo-controlled study of 72 bone marrow transplant recipients with asymptomatic CMV infection (CMV positive culture of urine, throat or blood) there was a reduction in the incidence of CMV disease in patients treated with intravenous Ganciclovir following successful hematopoietic engraftment. Patients with virologic evidence of CMV infection received intravenous Ganciclovir 5 mg/kg twice daily for 7 days followed by 5 mg/kg once daily through day 100 post-transplant. One of the 37 (3%) patients treated with intravenous Ganciclovir vs 15 of the 35 (43%) placebo-treated patients developed CMV disease during the study. At 6 months post-transplant, there continued to be a reduction in the incidence of CMV disease in patients treated with intravenous Ganciclovir. Six of 37 (16%) patients treated with intravenous Ganciclovir vs 15 of the 35 (43%) placebo-treated patients developed disease through 6 months post-transplant. The overall rate of survival was higher in the group treated with intravenous Ganciclovir, both at day 100 and day 180 post-transplant. Although the differences in hematologic toxicities were not statistically significant, the incidence of neutropenia was higher in the group treated with intravenous Ganciclovir [seeDosage and Administration (2.4), Adverse Reactions (6.1)].

Trial ICM 1570

This was a randomized, unblinded trial which evaluated 40 allogeneic bone marrow transplant recipients at risk for CMV disease. Patients underwent bronchoscopy and bronchoalveolar lavage (BAL) on day 35 post-transplant. Patients with histologic, immunologic or virologic evidence of CMV infection in the lung were then randomized to observation or treatment with intravenous Ganciclovir (5 mg/kg twice daily for 14 days followed by 5 mg/kg once daily 5 days/week until day 120). Four of 20 (20%) patients treated with intravenous Ganciclovir and 14 of 20 (70%) control patients developed interstitial pneumonia. The incidence of CMV disease was lower in the group treated with intravenous Ganciclovir [see Dosage and Administration (2.4)].
