Hivid (Tablet, Film Coated)

dailymed-instance:dosage |
Patients should be advised that HIVID is recommended
for use in combination with active antiretroviral therapy. Greater activity
has been observed when new antiretroviral therapies are begun at the same
time as HIVID. Concomitant therapy should be based on a patient's prior
drug exposure. The recommended regimenis one 0.750 mg tablet of HIVID orally
every 8 hours (2.25 mg HIVID total daily dose) in combination with other antiretroviral
agents. Please refer to the complete product information for each of the other
antiretroviral agents for the recommended doses of these agents. Based on
preliminary data, the recommended HIVID dosage reduction for patients with
impaired renal function is: creatinine clearance 10 to 40 mL/min: 0.750 mg
of HIVID every 12 hours; creatinine clearance<10 mL/min: 0.750 mg of HIVID
every 24 hours.<br/>Monitoring of Patients: Complete blood counts and clinical chemistry tests
should be performed prior to initiating HIVID therapy and at appropriate intervals
thereafter. For comprehensive patient monitoring recommendations for other
antiretroviral therapies, physicians should refer to the complete product
information for these drugs. Serum amylase levels should be monitored in those
individuals who have a history of elevated amylase, pancreatitis, ethanol
abuse, who are on parenteral nutrition or who are otherwise at high risk of
pancreatitis. Careful monitoring for signs or symptoms suggestive of peripheral
neuropathy is recommended, particularly in individuals with a low CDcell
count or who are at a greater risk of developing peripheral neuropathy while
on therapy .<br/>Dose Adjustment for HIVID: For toxicities that are likely to be associated
with HIVID (eg, peripheral neuropathy, severe oral ulcers, pancreatitis, elevated
liver function tests especially in patients with chronic Hepatitis B), HIVID
should be interrupted or dose reduced. FOR SEVERE TOXICITIES OR THOSE PERSISTING
AFTER DOSE REDUCTION, HIVID SHOULD BE INTERRUPTED. For recipients of combination
therapy with HIVID and other antiretroviral agents, dose adjustments or interruption
for each drug should be based on the known toxicity profile of the individual
drugs. SEE INFORMATION FOR EACH DRUG USED IN COMBINATION FOR A DESCRIPTION
OF KNOWN DRUG-ASSOCIATED ADVERSE REACTIONS. Patients
developing moderate discomfort with signs or symptoms of peripheral neuropathy
should stop HIVID. HIVID-associated peripheral neuropathy may continue to
worsen despite interruption of HIVID. HIVID should be reintroduced at 50%
dose���0.375 mg every 8 hours only if all findings related to peripheral
neuropathy have improved to mild symptoms. HIVID should be permanently discontinued
if patients experience severe discomfort related to peripheral neuropathy
or moderate discomfort that progresses. If other moderate to severe clinical
adverse reactions or laboratory abnormalities (such as increased liver function
tests) occur, then HIVID and/or the other potential causative agent(s) should
be interrupted until the adverse reaction abates. HIVID and/or the other potential
causative agent(s) should then be carefully reintroduced at lower doses if
appropriate. If adverse reactions recur at the reduced dose, therapy should
be discontinued. The minimum effective dose of HIVID in combination with zidovudine
for the treatment of adult patients with advanced HIV infection has not been
established. In patients with poor bone marrow
reserve, particularly those patients with advanced symptomatic HIV disease,
frequent monitoring of hematologic indices is recommended to detect serious
anemia or granulocytopenia. Significant toxicities, such as anemia (hemoglobin
of<7.5 gm/dL or reduction of>25% of baseline) and/or granulocytopenia
(granulocyte count of<750 cells/mmor reduction of>50% from
baseline), may require a treatment interruption of HIVID and zidovudine until
evidence of marrow recovery is observed. For less severe anemia or granulocytopenia,
a reduction in daily dose of zidovudine in those patients receiving combination
therapy may be adequate. In patients who experience hematologic toxicity,
reduction in hemoglobin may occur as early as 2 to 4 weeks afterinitiation
of therapy, and granulocytopenia usually occurs after 6 to 8 weeks of therapy.
In patients who develop significant anemia, dose modification does not necessarily
eliminate the need for transfusion. If marrow recovery occurs following dose
modification, gradual increases in dose may be appropriate depending on hematologic
indices and patient tolerance. For more details, refer to the complete product
information for zidovudine.

WARNING: THE USE OF HIVID
HAS BEEN ASSOCIATED WITH SIGNIFICANT CLINICAL ADVERSE REACTIONS, SOME OF WHICH
ARE POTENTIALLY FATAL. HIVID CAN CAUSE SEVERE PERIPHERAL NEUROPATHY AND BECAUSE
OF THIS SHOULD BE USED WITH EXTREME CAUTION IN PATIENTS WITH PREEXISTING NEUROPATHY.
HIVID MAY ALSO RARELY CAUSE PANCREATITIS AND PATIENTS WHO DEVELOP ANY SYMPTOMS
SUGGESTIVE OF PANCREATITIS WHILE USING HIVID SHOULD HAVE THERAPY SUSPENDED
IMMEDIATELY UNTIL THIS DIAGNOSIS IS EXCLUDED. LACTIC ACIDOSIS AND SEVERE
HEPATOMEGALY WITH STEATOSIS, INCLUDING FATAL CASES, HAVE BEEN REPORTED WITH
THE USE OF ANTIRETROVIRAL NUCLEOSIDE ANALOGUES ALONE OR IN COMBINATION, INCLUDING
HIVID . IN ADDITION,
RARE CASES OF HEPATIC FAILURE AND DEATH CONSIDERED POSSIBLY RELATED TO UNDERLYING
HEPATITIS B AND HIVID HAVE BEEN REPORTED .

Acute Overdosage: Inadvertent pediatric overdoses have occurred with
doses up to 1.5 mg/kg HIVID. Pediatric patients had prompt gastric lavage
and treatment with activated charcoal and had no sequelae. Mixed overdoses
including HIVID and other drugs have led to drowsiness and vomiting (with
HIVID or placebo, zidovudine and trimethoprim/sulfamethoxazole [TMP/SMX]),
or increased GGT (with 18.75 mg HIVID withzidovudine and lormetazepam) or
increased creatine phosphokinase (with HIVID or placebo, zidovudine, fluconazole,
dapsone and wine). There is no experience with acute HIVID overdosage at higher
doses and sequelae are unknown. There is no known antidote for HIVID overdosage.
It is not known whether zalcitabine is dialyzable by peritoneal dialysis or
hemodialysis.<br/>Chronic Overdosage: In an initial dose-finding study in which zalcitabine
was administered at doses 25 times (0.25 mg/kg every 8 hours) the currently
recommended dose, one patient discontinued HIVID after 1��weeks of treatment
subsequent to the development of a rash and fever. In the early Phase 1 studies,
all patients receiving zalcitabine at approximately 6 times the current total
daily recommended dose experienced peripheral neuropathy by week 10. Eighty
percent of patients who received approximately 2 times the current total daily
recommended dose experienced peripheral neuropathy by week 12.

HIVID is indicated in combination with antiretroviral
agents for the treatment of HIV infection. This indication is based on study
results showing a reduction in the rate of disease progression (AIDS-defining
events or death) in patients with limited prior antiretroviral therapy who
were treated with the combination of HIVID and zidovudine (see Description of Clinical Studies).
This indication is also based on a study showing a reduction in both mortality
and AIDS-defining clinical events for patients who received INVIRASE (saquinavir
mesylate) in combination with HIVID compared to patients who received either
HIVID or INVIRASE alone.<br/>Description of Clinical Studies: The use of HIVID in combination with zidovudine
is based on the clinical results from study ACTG 175. ACTG 175 was a randomized,
double-blind, controlled trial that compared zidovudine 200 mg three times
daily; didanosine 200 mg twice daily; zidovudine+didanosine; and zidovudine+HIVID
0.750 mg three times daily. A total of 2467 HIV-infected adults (mean baseline
CDcount = 352 cells/mm) with no prior AIDS-defining
event enrolled with the following demographics: male (82%), Caucasian (70%),
mean age of 35 years, asymptomatic HIV infection (81%) and prior antiretroviral
use (57%, mean duration = 89.5 weeks). The overall mean duration of study
treatment was 99 weeks. The incidence of AIDS-defining events or death is
shown in Table 1. Although no antiretroviral agent should be used
as monotherapy, a description of CPCRA 002 is included here as it provides
a comparison of the safety and efficacy of HIVID compared to ddI. CPCRA 002 was a randomized, multicenter, open-label study
in which HIVID was compared to ddI as treatment for patients with advanced
HIV infection (median CDcell count = 37 cells/mm)
who were clinically intolerant to ZDV, or who had met criteria for having
disease progression while receiving ZDV.Patients in this study
had a mean of 17.5 months of prior ZDV use. The median duration of treatment
for both HIVID and ddI was 34 weeks. The results demonstrate that HIVID was
at least as efficacious as ddI in terms of time to an AIDS-defining event
or death, while for survival alone the results favored HIVID. However, most
of the patients (66%) in either group had disease progression over the median
16 months of follow-up. Overall rates of study drug intolerance, discontinuation
and adverse events were similar for the two groups, although the types of
events were different. A clinical study (N3300/ACTG
114) has demonstrated ZDV to be superior to HIVID as monotherapy for advanced
HIV disease (CDcell count���200 cells/mm) in
previously untreated patients.The final analysis of this study
indicated that 134 patients (42%) in the HIVID group with a median follow-up
of 85 weeks and 120 patients (38%) in the ZDV group with a median follow-up
of 96 weeks died with a relative risk for mortality of ZDV to HIVID of 0.54.
