Pregnancy Cat

There are no clinical studies of Atezolizumab in pregnant women. Atezolizumab is not recommended during pregnancy unless the potential benefit for the mother outweighs the potential risk to the fetusIt 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

Immune-related pneumonitis: Cases of pneumonitis, including fatal cases, have been observed in clinical trials with Atezolizumab. Patients should be monitored for signs and symptoms of pneumonitis. Immune-related hepatitis: Cases of hepatitis, some leading to fatal outcomes, have been observed in clinical trials with Atezolizumab. 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 Atezolizumab. 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 Atezolizumab. 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 Atezolizumab. Patients should be monitored for clinical signs and symptoms of endocrinopathies. Monitor thyroid function prior to and periodically during treatment with Atezolizumab. Consider appropriate management of patients with abnormal thyroid function tests at baseline. Patients with abnormal thyroid function tests who are asymptomatic may receive Atezolizumab.

Mode Of Action

Binding of PD-L1 to the PD-1 and B7.1 receptors found on T cells suppresses cytotoxic T-cell activity through the inhibition of T-cell proliferation and cytokine production. PD-L1 may be expressed on tumor cells and tumor-infiltrating immune cells, and can contribute to the inhibition of the antitumor immune response in the microenvironment. 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
