What Is Valcyte?

Valcyte (valganciclovir hydrochloride) is an antiviral drug that treats cytomegalovirus (CMV) infection of the eye in patients with acquired immunodeficiency syndrome (AIDS). Valcyte also prevents CMV infection in patients who have received an organ transplant (kidney, heart, or kidney-pancreas).

What Are Side Effects of Valcyte?

Common side effects of Valcyte include:

Tell your doctor if you have unlikely but serious side effects of Valcyte including:

Dosage for Valcyte

Dose of Valcyte varies depending on the infection being treated, the patient's medical condition, and other factors. Valcyte and ganciclovir (Cytovene) must never be taken together.

What Drugs, Substances, or Supplements Interact with Valcyte?

Valcyte may interact with zidovudine, didanosine, mycophenolate, drugs that weaken your immune system (such as cancer medicine or steroids), or probenecid. Tell your doctor all prescription and over-the-counter medications you use.

Valcyte During Pregnancy and Breastfeeding

Women who are pregnant or who may become pregnant should not handle this medication. During pregnancy, Valcyte should be used only when prescribed. It may harm a fetus. Men and women should consult their doctors about use of birth control. It is unknown if this medication passes into breast milk. It may have undesirable effects on a nursing infant. Breastfeeding while using this drug is not recommended. If you have HIV, do not breastfeed because breast milk can transmit HIV.

SIDE EFFECTS

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

  • Hematologic Toxicity [see WARNINGS AND PRECAUTIONS].
  • Acute Renal Failure [see WARNINGS AND PRECAUTIONS].
  • Impairment of Fertility [see WARNINGS AND PRECAUTIONS].
  • Fetal Toxicity [see WARNINGS AND PRECAUTIONS].
  • Mutagenesis and Carcinogenesis [see WARNINGS AND PRECAUTIONS].

The most common adverse reactions and laboratory abnormalities reported in at least one indication by greater than or equal to 20% of adult patients treated with VALCYTE tablets are diarrhea, pyrexia, fatigue, nausea, tremor, neutropenia, anemia, leukopenia, thrombocytopenia, headache, insomnia, urinary tract infection, and vomiting. The most common reported adverse reactions and laboratory abnormalities reported in greater than or equal to 20% of pediatric solid organ transplant recipients treated with VALCYTE for oral solution or tablets are diarrhea, pyrexia, upper respiratory tract infection, urinary tract infection, vomiting, neutropenia, leukopenia, and headache.

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 rates observed in practice.

Valganciclovir, a prodrug of ganciclovir, is rapidly converted to ganciclovir after oral administration. Adverse reactions known to be associated with ganciclovir usage can therefore be expected to occur with VALCYTE.

Adverse Reactions In Adults

Treatment Of CMV Retinitis In AIDS Patients

In a clinical study for the treatment of CMV retinitis in HIV-infected patients, the adverse reactions reported by patients receiving VALCYTE tablets (n=79) or intravenous ganciclovir (n=79) for 28 days of randomized therapy (21 days induction dose and 7 days maintenance dose), respectively, included diarrhea (16%, 10%), nausea (8%, 14%), and headache (9%, 5%). The incidence of adverse reactions was similar between the group who received VALCYTE tablets and the group who received intravenous ganciclovir. The frequencies of neutropenia (ANC less than 500/μL) were 11% for patients receiving VALCYTE tablets compared with 13% for patients receiving intravenous ganciclovir. Anemia (Hgb less than 8 g/dL) occurred in 8% of patients in each group. Other laboratory abnormalities occurred with similar frequencies in the two groups.

Adverse reactions and laboratory abnormalities are available for 370 patients who received maintenance therapy with VALCYTE tablets 900 mg once daily in two open-label clinical trials. Approximately 252 (68%) of these patients received VALCYTE tablets for more than nine months (maximum duration was 36 months). Table 3 and Table 4 show pooled selected adverse reactions and abnormal laboratory values from these patients.

Prevention Of CMV Disease In Solid Organ Transplant Patients

Table 5 shows selected adverse reactions regardless of severity with an incidence of greater than or equal to 5% from a clinical trial (up to 28 days after study treatment) where heart, kidney, kidney-pancreas and liver transplant patients received VALCYTE tablets (N=244) or oral ganciclovir (N=126) until Day 100 post-transplant. The majority of the adverse reactions were of mild or moderate intensity.

Table 6 shows selected adverse reactions regardless of severity with an incidence of greater than or equal to 5% from another clinical trial where kidney transplant patients received either valganciclovir once daily starting within 10 days post-transplant until Day 100 post-transplant followed by 100 days of placebo or valganciclovir once daily until Day 200 post-transplant. The overall safety profile of VALCYTE did not change with the extension of prophylaxis until Day 200 post-transplant in high risk kidney transplant patients.

Adverse Reactions In Pediatric Patients

VALCYTE for oral solution and tablets have been studied in 179 pediatric solid organ transplant patients who were at risk for developing CMV disease (aged 3 weeks to 16 years) and in 24 neonates with symptomatic congenital CMV disease (aged 8 to 34 days), with duration of ganciclovir exposure ranging from 2 to 200 days [see Use In Specific Populations, Clinical Studies].

Prevention Of CMV Disease In Pediatric Solid Organ Transplant Patients

The most frequently reported adverse reactions (greater than 10% of patients), regardless of seriousness, in pediatric solid organ transplant patients taking VALCYTE until Day 100 post-transplant were diarrhea, pyrexia, upper respiratory tract infection, vomiting, anemia, neutropenia, constipation and nausea. The most frequently reported adverse reactions (greater than 10% of patients) in pediatric kidney transplant patients treated with valganciclovir until Day 200 post-transplant were upper respiratory tract infection, urinary tract infection, diarrhea, leukopenia, neutropenia, headache, abdominal pain, tremor, pyrexia, anemia, blood creatinine increased, vomiting, and hematuria.

In general, the safety profile was similar in pediatric patients compared to that observed in adult patients. However, the rates of certain adverse reactions, and laboratory abnormalities, such as upper respiratory tract infection, pyrexia, nasopharyngitis, anemia, and abdominal pain were reported more frequently in pediatric patients than in adults [see Use In Specific Populations, Clinical Studies]. Neutropenia was reported at a higher incidence in the two pediatric studies as compared to adults, but there was no correlation between neutropenia and infections observed in the pediatric population.

The overall safety profile of VALCYTE was similar with the extension of prophylaxis until Day 200 post-transplant in high risk pediatric kidney transplant patients. However, the incidence of severe neutropenia (ANC < 500/μL) was higher in pediatric kidney transplant patients treated with VALCYTE until Day 200 (17/57, 30%) compared to pediatric kidney transplant patients treated until Day 100 (3/63, 5%). There were no differences in the incidence of severe (Grade 4) anemia or thrombocytopenia in patients treated 100 or 200 days with VALCYTE.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of VALCYTE. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. As VALCYTE is rapidly and extensively converted to ganciclovir, any adverse reactions associated with ganciclovir might also occur with valganciclovir.

  • Anaphylactic reaction
  • Agranulocytosis
  • Granulocytopenia

In general, the adverse reactions reported during the postmarketing use of VALCYTE were similar to those identified during the clinical trials.
