What is Pemazyre?
From the FDA label:Pemigatinib is a kinase inhibitor with the chemical name 3-(2,6-difluoro-3,5-dimethoxyphenyl)-1-ethyl-8-(morpholin-4-ylmethyl)-1,3,4,7-tetrahydro-2 H -pyrrolo[3',2':5,6]pyrido[4,3- d ]pyrimidin-2-one. Pemigatinib has a molecular formula of C 24 H 27 F 2 N 5 O 4 and molecular mass of 487.5 g/mole. Pemigatinib has the following chemical structure: Pemigatinib is a white to off-white solid that is not hygroscopic. The solubility of pemigatinib is pH dependent with decreasing solubility observed with increasing pH. PEMAZYRE tablets are uncoated and for oral administration. Tablets are available containing 4.5 mg, 9 mg, or 13.5 mg of pemigatinib active ingredient. The inactive ingredients include magnesium stearate, microcrystalline cellulose, and sodium starch glycolate. Chemical Structure
How to use
Cholangiocarcinoma: Confirm the presence of an FGFR2 fusion or rearrangement prior to initiation of treatment with PEMAZYRE. ( 2.1 ) Recommended dosage is 13.5 mg orally once daily for 14 consecutive days followed by 7 days off therapy in 21-day cycles. Continue treatment until disease progression or unacceptable toxicity occurs. ( 2.2 ) Myeloid/lymphoid neoplasms with FGFR1 rearrangement: Recommended dosage is 13.5 mg orally once daily.

( 2.2 ) Severe Renal Impairment: the recommended dosage of PEMAZYRE is 9 mg with the schedule (intermittent or continuous) designated for the indication. ( 2.5 , 8.6 , 12.3 ) Severe Hepatic Impairment: the recommended dosage of PEMAZYRE is 9 mg with the schedule (intermittent or continuous) designated for the indication. ( 2.6 , 8.7 , 12.3 ) 2.1 Patient Selection Select patients for the treatment of locally advanced or metastatic cholangiocarcinoma with PEMAZYRE based on the presence of an FGFR2 fusion or rearrangement as detected by an FDA-approved test [see Clinical Studies ( 14.1 )]. Information on FDA-approved test(s) for the detection of an FGFR2 fusion or rearrangement in cholangiocarcinoma is available at http://www.fda.gov/CompanionDiagnostics .

Warnings
Important safety information
Ocular Toxicity : PEMAZYRE can cause retinal pigment epithelial detachment. Perform ophthalmological examination including optical coherence tomography (OCT) prior to initiation of therapy, every 2 months for the first 6 months of treatment and every 3 months thereafter, and urgently at any time for visual symptoms. ( 2.3 , 5.1 ) Hyperphosphatemia and Soft Tissue Mineralization : PEMAZYRE can cause hyperphosphatemia leading to soft tissue mineralization, cutaneous calcification, calcinosis, and non-uremic calciphylaxis. Monitor for hyperphosphatemia and withhold, reduce the dose, or permanently discontinue based on duration and severity of hyperphosphatemia. ( 2.3 , 5.2 ) Embryo-Fetal Toxicity : Can cause fetal harm. Advise patients of reproductive potential of the potential risk to the fetus and use effective contraception. ( 5.3 , 8.1 , 8.3 ) 5.1 Ocular Toxicity Retinal Pigment Epithelial Detachment (RPED) PEMAZYRE can cause RPED, which may cause symptoms such as blurred vision, visual floaters, or photopsia. Clinical trials of PEMAZYRE did not conduct routine monitoring including optical coherence tomography (OCT) to detect asymptomatic RPED; therefore, the incidence of asymptomatic RPED with PEMAZYRE is unknown. Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, RPED occurred in 11% of patients, including Grade 3-4 RPED in 1.3%. The median time to first onset of RPED was 56 days. RPED led to dose interruption of PEMAZYRE in 3.1% of patients, and dose reduction and permanent discontinuation in 1.3% and in 0.2% of patients, respectively. RPED resolved or improved to Grade 1 levels in 76% of patients who required dosage modification of PEMAZYRE for RPED. Perform a comprehensive ophthalmological examination including OCT prior to initiation of PEMAZYRE and every 2 months for the first 6 months and every 3 months thereafter during treatment. For onset of visual symptoms, refer patients for ophthalmologic evaluation urgently, with follow-up every 3 weeks until resolution or discontinuation of PEMAZYRE. Modify the dose or permanently discontinue PEMAZYRE as recommended [see Dosage and Administration ( 2.3 )] . Dry Eye Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, dry eye occurred in 31% of patients, including Grade 3-4 in 1.6% of patients. Treat patients with ocular demulcents as needed. 5.2 Hyperphosphatemia and Soft Tissue Mineralization PEMAZYRE can cause hyperphosphatemia leading to soft tissue mineralization, cutaneous calcification, calcinosis, and non-uremic calciphylaxis. Increases in phosphate levels are a pharmacodynamic effect of PEMAZYRE [see Clinical Pharmacology ( 12.2 )] . Among 635 patients who received a starting dose of PEMAZYRE 13.5 mg across clinical trials, hyperphosphatemia was reported in 93% of patients based on laboratory values above the upper limit of normal. The median time to onset of hyperphosphatemia was 8 days (range 1-169). Phosphate lowering therapy was required in 33% of patients receiving PEMAZYRE. Monitor for hyperphosphatemia and initiate a low phosphate diet when serum phosphate level is > 5.5 mg/dL. For serum phosphate levels > 7 mg/dL, initiate phosphate lowering therapy and withhold, reduce the dose, or permanently discontinue PEMAZYRE based on duration and severity of hyperphosphatemia [see Dosage and Administration ( 2.3 )]. 5.3 Embryo-Fetal Toxicity Based on findings in an animal study and its mechanism of action, PEMAZYRE can cause fetal harm when administered to a pregnant woman. Oral administration of pemigatinib to pregnant rats during the period of organogenesis caused fetal malformations, fetal growth retardation, and embryo-fetal death at maternal exposures lower than the human exposure based on area under the curve (AUC) at the clinical dose of 13.5 mg. Advise pregnant women of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment with PEMAZYRE and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with PEMAZYRE and for 1 week after the last dose [see Use in Specific Populations ( 8.1 , 8.3 )] .

Interactions
Strong and Moderate CYP3A Inducers: Avoid concomitant use of PEMAZYRE. ( 7.1 ) Strong and Moderate CYP3A Inhibitors: Avoid concomitant use. If concomitant use cannot be avoided, reduce PEMAZYRE dosage. ( 2.4 , 7.1 ) 7.1 Effect of Other Drugs on PEMAZYRE Strong and Moderate CYP3A Inducers Concomitant use of PEMAZYRE with a strong or moderate CYP3A inducer decreases pemigatinib plasma concentrations [ see Clinical Pharmacology ( 12.3 )], which may reduce the efficacy of PEMAZYRE. Avoid concomitant use of strong and moderate CYP3A inducers with PEMAZYRE. Strong and Moderate CYP3A Inhibitors Concomitant use of a strong or moderate CYP3A inhibitor with PEMAZYRE increases pemigatinib plasma concentrations [see Clinical Pharmacology ( 12.3 )], which may increase the incidence and severity of adverse reactions. Avoid concomitant use of strong and moderate CYP3A inhibitors with PEMAZYRE. Reduce PEMAZYRE dosage if concomitant use of strong and moderate CYP3A inhibitors cannot be avoided [see Dosage and Administration ( 2.4 )] .
Storing Pemazyre, and how long it keeps
Quoted from this product’s own FDA label. Storage belongs to the product and its device, not to the drug in general — a pen and a tablet of the same medicine are kept completely differently.
- “Store PEMAZYRE tablets at room temperature 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).”
