Carcinogenesis, Mutagenesis, Impairment of Fertility
In a two year rat carcinogenicity study a higher incidence of uterine adenocarcinoma, relative to controls, was observed in females receiving 30 mg/kg/day (at least 174 times human AUC exposure after a 1 mg twice daily dose). Adrenal phaeochromocytomas were increased relative to controls in males receiving 3 mg/kg/day and above, and in females receiving 10 mg/kg/day and above (at least 10 and 18 times respectively human AUC exposure after a 1 mg twice daily dose).
Anagrelide hydrochloride was not mutagenic in the bacterial mutagenesis (Ames) assay or the mouse lymphoma cell (L5178Y, TK+/-) forward mutation assay, and was not clastogenic in the in vitro chromosome aberration assay using human lymphocytes or the in vivo mouse micronucleus test.
Anagrelide hydrochloride at oral doses up to 240 mg/kg/day (233 times the recommended human dose of 10 mg/day based on body surface area) had no effect on fertility and reproductive function of male rats. However, in fertility studies in female rats, oral doses of 30 mg/kg/day (29 times the recommended maximum human dose based on body surface area) or higher resulted in increased pre- and post-implantation loss and a decrease in the number of live embryos.
Animal Toxicology and/or Pharmacology
In the 2-year rat study, a significant increase in non-neoplastic lesions was observed in Anagrelide treated males and females in the adrenal (medullary hyperplasia), heart (myocardial hypertrophy and chamber distension), kidney (hydronephrosis, tubular dilation and urothelial hyperplasia) and bone (femur enostosis). Vascular effects were observed in tissues of the pancreas (arteritis/periarteritis, intimal proliferation and medial hypertrophy), kidney (arteritis/periarteritis, intimal proliferation and medial hypertrophy), sciatic nerve (vascular mineralization), and testes (tubular atrophy and vascular infarct) in Anagrelide treated males.

Special Populations Hepatic Function Impairment
AUC increased 8-fold with moderate hepatic function impairment.
Platelet count (every 2 days during the first week of treatment and at least weekly until the maintenance dose is reached; continue to monitor after cessation of treatment); CBC with differential (monitor closely during first 2 weeks of treatment), liver function (ALT and AST; baseline and during treatment), BUN, and serum creatinine (monitor closely during first weeks of treatment); serum electrolytes; blood pressure; heart rate; cardiovascular exam, including ECG (pretreatment; monitor during therapy); signs/symptoms of interstitial lung disease; monitor for thrombosis or bleeding
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, vomiting, flatulence, diarrhea, or abdominal pain. Have patient report immediately to prescriber signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; hematuria; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe or persistent bleeding), signs of a severe pulmonary disorder (lung or breathing problems like difficulty breathing, shortness of breath, or a cough that is new or worse), signs of pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), angina, tachycardia, abnormal heartbeat, shortness of breath, excessive weight gain, swelling of arms or legs, severe dizziness, passing out, severe headache, severe loss of strength and energy, vision changes, urinary retention, change in amount of urine passed, depression, confusion, memory impairment, seizures, or burning or numbness feeling (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.

This information is intended to serve as a concise initial reference for healthcare professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience and judgment in diagnosing, treating and advising patients.
Liver Dose Adjustments
Use of anagrelide in patients with severe hepatic impairment is contraindicated. Patients with moderate hepatic impairment should receive a starting dose of 0.5 mg/day and be maintained at that dose for a minimum of 1 week (careful monitoring of cardiovascular effects should be instituted during this time). Incremental increases should not exceed more than 0.5 mg/day in any 1 week.
-Anagrelide has not been studied in pediatric patients less than 7 years of age.
