OLINZA due to adverse reactions. These adverse reactions included increased serum creatinine, decreased appetite, hypokalemia, leukopenia, nausea, neutropenia, thrombocytopenia and vomiting. The median time to the first adverse reactions resulting in dose reduction was 42 days (range 17 to 263 days).
Laboratory Abnormalities
Laboratory abnormalities were reported in all of the 86 CTCL patients who received the 400-mg once-daily dose.
Increased serum glucose was reported as a laboratory abnormality in 69% (59/86) of CTCL patients who received the 400-mg once daily dose; only 4 of these abnormalities were severe (Grade 3). Increased serum glucose was reported as an adverse reaction in 8.1% (7/86) of CTCL patients who received the 400-mg once daily dose. [See Warnings and Precautions (5.4).]
Transient increases in serum creatinine were detected in 46.5% (40/86) of CTCL patients who received the 400-mg once daily dose. Of these laboratory abnormalities, 34 were NCI CTCAE Grade 1, 5 were Grade 2, and 1 was Grade 3.
Proteinuria was detected as a laboratory abnormality (51.4%) in 38 of 74 patients tested. The clinical significance of this finding is unknown.
Dehydration
Based on reports of dehydration as a serious drug-related adverse reaction in clinical trials, patients were instructed to drink at least 2 L/day of fluids for adequate hydration. [See Warnings and Precautions (5.3, 5.5).]
Adverse Reactions in Non-CTCL Patients
The frequencies of individual adverse reactions were substantially higher in the non-CTCL population. Drug-related serious adverse reactions reported in the non-CTCL population which were not observed in the CTCL population included single events of blurred vision, asthenia, hyponatremia, tumor hemorrhage, Guillain-Barré syndrome, renal failure, urinary retention, cough, hemoptysis, hypertension, and vasculitis.
In patients recovering from bowel surgery and treated perioperatively with ZOLINZA, anastomotic healing complications including fistulas, perforations, and abscess formation have occurred.
7 DRUG INTERACTIONS
7.1 Coumarin-Derivative Anticoagulants
Prolongation of prothrombin time (PT) and International Normalized Ratio (INR) were observed in patients receiving ZOLINZA concomitantly with coumarin-derivative anticoagulants. Physicians should monitor PT and INR more frequently in patients concurrently administered ZOLINZA and coumarin derivatives.
7.2 Other HDAC Inhibitors
Severe thrombocytopenia and gastrointestinal bleeding have been reported with concomitant use of ZOLINZA and other HDAC inhibitors (e.g., valproic acid). Monitor platelet count every 2 weeks for the first 2 months. [See Warnings and Precautions (5.6).]
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category D [See Warnings and Precautions (5.7)]
8.3 Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from ZOLINZA, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
8.4 Pediatric Use
The safety and effectiveness of ZOLINZA in pediatric patients have not been established.
8.5 Geriatric Use
Of the total number of patients with CTCL in trials (N=107), 46 % were 65 years of age and over, while 15 % were 75 y
