Nab-Xelpac

Generic Name :Nanoparticle Albumin Bound Paclitaxel

Indications

Metastatic Breast Cancer: Nab-Xelpac is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated.

Non-Small Cell Lung Cancer: Nab-Xelpac is indicated for the first-line treatment of locally advanced or metastatic non-small cell lung cancer, in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy.

Adenocarcinoma Of The Pancreas: Nab-Xelpac is indicated for the first-line treatment of patients with metastatic adenocarcinoma of the pancreas, in combination with gemcitabine.

Pharmacology

Nab-Paclitaxelis a microtubule inhibitor that promotes the assembly of microtubules from tubulin dimers and stabilizes microtubules by preventing depolymerization. This stability results in the inhibition of the normal dynamic reorganization of the microtubule network that is essential for vital interphase and mitotic cellular functions. Paclitaxel induces abnormal arrays or “bundles” of microtubules throughout the cell cycle and multiple asters of microtubules during mitosis.

Dosage & Administration

Metastatic Breast Cancer: After failure of combination chemotherapy for metastatic breast cancer or relapse within 6 months of adjuvant chemotherapy, the recommended regimen for Nab-Paclitaxel is 260 mg/m² administered intravenously over 30 minutes every 3 weeks.

Non-Small Cell Lung Cancer: The recommended dose of Nab-Paclitaxel is 100 mg/m² administered as an intravenous infusion over 30 minutes on Days 1, 8, and 15 of each 21-day cycle. Administer carboplatin on Day 1 of each 21 day cycle immediately after Nab-Paclitaxel.

Adenocarcinoma Of The Pancreas: The recommended dose of Nab-Paclitaxel is 125 mg/m² administered as an intravenous infusion over 30-40 minutes on Days 1, 8 and 15 of each 28-day cycle. Administer gemcitabine immediately after Nab-Paclitaxel on Days 1, 8 and 15 of each 28-day cycle.

Dosage In Patients With Hepatic Impairment: For patients with mild hepatic impairment (total bilirubin greater than ULN and less than or equal to 1.5 x ULN and aspartate aminotransferase [AST] less than or equal to 10 x ULN), no dose adjustments are required, regardless of indication.

Do not administer Nab-Paclitaxel to patients with metastatic adenocarcinoma of the pancreas who have moderate to severe hepatic impairment. Do not administer Nab-Paclitaxel to patients with total bilirubin greater than 5 x ULN or AST greater than 10 x ULN regardless of indication as these patients have not been studied.
