Dacocent(Dacomitinib)
Therapeutic Group: Anti Cancer
Presentation
Dacocent 45: Each film coated tablet contains Dacomitinib Monohydrate INN equivalent to Dacomitinib 45 mg.
Description
Dacomitinib is an irreversible inhibitor of the kinase activity of the human EGFR family (EGFR/HER1, HER2, and HER4)and certain EGFR activating mutations (exon 19 deletion or the exon 21 L858R substitution mutation). In vitro Dacomitinib also inhibited the activity of DDR1, EPHA6, LCK, DDR2, and MNK1 at clinically relevant concentrations. Dacomitinib demonstrated dose-dependent inhibition of EGFR and HER2 autophosphorylation and tumor growth in mice bearing subcutaneously implanted human tumor xenografts driven by HER family targets including mutated EGFR. Dacomitinib also exhibited antitumor activity in orally-dosed mice bearing intracranial human tumor xenografts driven by EGFR amplifications
Indications
Dacomitinib is a kinase inhibitor indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletion or exon 21 L858R substitution mutations as detected by an FDA-approved test
Dosage & Administration
The recommended dosage of Dacomitinib is 45 mg taken orally once daily, until disease progression or unacceptable toxicity occurs. Dacomitinib can be taken with or without food.
Take Dacomitinib the same time each day. If the patient vomits or misses a dose, do not take an additional dose or make up a missed dose but continue with the next scheduled dose.
First dose reduction Dose Level- 30 mg Dose (Once Daily)

Precautions
Warnings & Precautions
• Interstitial Lung Disease (ILD): Permanently discontinue DACOMITINIB if ILD is confirmed
• Diarrhea: Withhold and reduce the dose of DACOMITINIB based on the severity
• Dermatologic Adverse Reactions: Withhold and reduce the dose of DACOMITINIB based on the severity
• Embryo-Fetal Toxicity: DACOMITINIB can cause fetal harm. Advise females of reproductive potential to use effective contraception.
Use in Pregnancy & Lactation
Dacomitinib can cause fetal harm when administered to a pregnant woman. There is no information regarding the presence of dacomitinib or its metabolites in human milk or their effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants from Dacomitinib,advise women not to breastfeed during treatment with DACOMITINIB and for at least 17 days after the last dose.
Drug Interaction
Proton Pump Inhibitors (PPIs): Avoid use with DACOMITINIB; use locally-acting antacids or H2-receptor antagonist; administer DACOMITINIB at least 6 hours before or 10 hours after H2-receptor antagonist
• CYP2D6 Substrates: Avoid concomitant use with DACOMITINIB where minimal increases in concentration of the CYP2D6 substrate may lead to serious or life-threatening toxicities
Storage
Do not store above 30 â°C. Keep away from light and out of the reach of children.
