Description
Indications
- After prior chemotherapy, or
- Who are considered cisplatin ineligibleand whose tumours have a PD-L1 expression ≥ 5%, or
- Who are not eligible for any platinum-containing chemotherapy regardless of level of tumor PD-L1 expression.
Tecentriq is indicated for the treatment of patients with locally advanced or metastatic non-small cell lung cancer NSCLC after prior chemotherapy.
Pharmacology
Atezolizumab is an Fc-engineered humanized immunoglobulin G1 (IgG1) monoclonal antibody that directly binds to PD-L1 and blocks interactions with the PD-1 and B7.1 receptors, releasing PD-L1 / PD-1 pathway-mediated inhibition of the immune response, including reactivating the antitumor immune response. Atezolizumab leaves the PD-L2/PD-1 interaction intact. In syngeneic mouse tumor models, blocking PD-L1 activity resulted in decreased tumor growth
Dosage & Administration
- 1200 mg administered by IV infusion every 3 weeks or
- 1680 mg administered by IV infusion every 4 weeks.
1L cisplatin-ineligible mUC: Patients should be selected for treatment based on the tumor expression of PD-L1 confirmed by a validated test
Contraindications
Pregnancy & Lactation
It is not known whether Atezolizumab is excreted in human breast milk. No studies have been conducted to assess the impact of Atezolizumab on milk production or its presence in breast milk.Asthe potential for harm to the nursing infant is unknown,a decision must be madeto either discontinue breast-feeding ordiscontinue Atezolizumabtherapy.
Precautions & Warnings
Immune-related hepatitis: Cases of hepatitis, some leading to fatal outcomes, have been observed in clinical trials with Tecentriq. Patients should be monitored for signs and symptoms of hepatitis. Monitor aspartate aminotransferase (AST), alanine aminotransferase (ALT) and bilirubin prior to and periodically during treatment with Tecentriq. Consider appropriate management of patients with abnormal liver function tests (LFTs) at baseline.
Immune-related colitis: Cases of diarrhea or colitis have been observed in clinical trials with Tecentriq. Patients should be monitored for signs and symptoms of colitis.
Immune-related endocrinopathies: Hypothyroidism, hyperthyroidism, adrenal insufficiency, hypophysitis, and type 1 diabetes mellitus, including diabetic ketoacidosis, have been observed in clinical trials with Tecentriq. Patients should be monitored for clinical signs and symptoms of endocrinopathies. Monitor thyroid function prior to and periodically during treatment with Tecentriq. Consider appropriate management of patients with abnormal thyroid function tests at baseline. Patients with abnormal thyroid function tests who are asymptomatic may receive Tecentriq.
Use in Special Populations
Geriatric use: Based on a population pharmacokinetic analysis, no dose adjustment of Tecentriq is required in patients ≥ 65 years of age
Renal impairment: Based on a population pharmacokinetic analysis, no dose adjustment is required in patients with renal impairment
Hepatic impairment: Based on a population pharmacokinetic analysis, no dose adjustment is required for patients with mild hepatic impairment. There are no data in patients with moderate or severe hepatic impairment
