PIQRAY

The pharmacokinetics of alpelisib has been studied in healthy subjects and adult patients with solid tumors. Steady-state alpelisib maximum plasma concentration (C max ) and AUC increased proportionally over the dose range of 30 mg to 450 mg (0.1 to 1.5 times the approved recommended dosage) under fed conditions. The mean accumulation of alpelisib is 1.3 to 1.5 and steady-state plasma concentrations are reached within 3 days following daily dosage. In adult patients who received PIQRAY 300 mg on...

SOLAR-1 (NCT02437318) was a randomized, double-blind, placebo-controlled trial of PIQRAY plus fulvestrant versus placebo plus fulvestrant in 572 patients with HR-positive, HER2-negative, advanced or metastatic breast cancer whose disease had progressed or recurred on or after an aromatase inhibitor-based treatment (with or without CDK4/6 combination). Patients were excluded if they had inflammatory breast cancer, diabetes mellitus Type 1 or uncontrolled Type 2, or pneumonitis. Randomization was stratified by presence of lung and/or liver metastasis and previous treatment with CDK4/6 inhibitor(...

PIQRAY is contraindicated in patients with severe hypersensitivity to it or any of its components [see Warnings and Precautions (5.1)] . Severe hypersensitivity to PIQRAY or to any of its components. ( 4 )

Severe Hypersensitivity : Permanently discontinue PIQRAY. Promptly initiate appropriate treatment. ( 5.1 ) Severe Cutaneous Adverse Reactions (SCARs) : PIQRAY can cause SCARs, including Stevens-Johnson syndrome (SJS), erythema multiforme (EM), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). Interrupt PIQRAY for signs or symptoms of SCARs. Permanently discontinue PIQRAY if SCARs are confirmed. ( 5.2 ) Hyperglycemia : PIQRAY can cause severe hyp...

7 DRUG INTERACTIONS CYP3A4 Inducers : Avoid coadministration of PIQRAY with a strong CYP3A4 inducer. Consider an alternative concomitant drug with no or minimal potential to induce CYP3A4. ( 7.1 ) Breast Cancer Resistance Protein (BCRP) Inhibitors : Avoid the use of BCRP inhibitors in patients treated with PIQRAY. If unable to use alternative drugs, closely monitor for increased adverse reactions....
