Pembrolizumab
Binding of the PD-1 ligands, PD-L1 and PD-L2, to the PD-1 receptor found on T cells, inhibits T cell proliferation and cytokine production. Upregulation of PD-1 ligands occurs in some tumors and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors. Pembrolizumab is a monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response. In syngeneic mouse tumor models, blocking PD-1 activity resulted in decreased tumor growth.

None.
Most common adverse reactions (reported in ≥20% of patients) were:Pemro as a single agent: fatigue, musculoskeletal pain, decreased appetite, pruritus, diarrhea, nausea, rash, pyrexia, cough, dyspnea, constipation, pain, and abdominal pain.Pemro in combination with chemotherapy: fatigue/asthenia, nausea, constipation, diarrhea, decreased appetite, rash, vomiting, cough, dyspnea, pyrexia, alopecia, peripheral neuropathy, mucosal inflammation, and stomatitis.Pemro in combination with axitinib: diarrhea, fatigue/asthenia, hypertension, hepatotoxicity, hypothyroidism, decreased appetite, palmar-plantar erythrodysesthesia, nausea, stomatitis/mucosal inflammation, dysphonia, rash, cough, and constipation.Pemro in combination with lenvatinib: fatigue, hypertension, musculoskeletal pain, diarrhea, decreased appetite, hypothyroidism, nausea, stomatitis, vomiting, decreased weight, abdominal pain, headache, constipation, urinary tract infection, dysphonia, hemorrhagic events, hypomagnesemia, palmar-plantar erythrodysesthesia, dyspnea, cough, and rash.
Based on its mechanism of action, Pembrolizumab can cause fetal harm when administered to a pregnant woman. There are no available human data informing the risk of embryo-fetal toxicity. There are no data on the presence of pembrolizumab in either animal or human milk or its effects on the breastfed child or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with Pembrolizumab and for 4 months after the final dose.
Immune-mediated pneumonitis: Withhold for moderate, and permanently discontinue for severe, life-threatening or recurrent moderate pneumonitis.Immune-mediated colitis: Withhold for moderate or severe, and permanently discontinue for life-threatening colitis.Immune-mediated hepatitis (Pemro) and hepatotoxicity (Pemro in combination with axitinib): Monitor for changes in hepatic function. Based on severity of liver enzyme elevations, withhold or discontinue Pemro, axitinib, or Pemro and axitinib. Consider corticosteroid therapy.Immune-mediated endocrinopathies:Adrenal insufficiency: Withhold for moderate and withhold or permanently discontinue for severe or life-threatening adrenal insufficiency.Hypophysitis: Withhold for moderate and withhold or permanently discontinue for severe or life-threatening hypophysitis.Thyroid disorders: Monitor for changes in thyroid function. Withhold or permanently discontinue for severe or life-threatening hyperthyroidism.Type 1 diabetes mellitus: Monitor for hyperglycemia. Withhold Pemro in cases of severe hyperglycemia.Immune-mediated nephritis: Monitor for changes in renal function. Withhold for moderate, and permanently discontinue for severe or life-threatening nephritis.Immune-mediated skin adverse reactions including, Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN): Withhold for severe and permanently discontinue for life-threatening skin reactions.Other immune-mediated adverse reactions: In organ transplant recipients, consider the benefit of treatment with Pemro versus the risk of possible organ rejection.Infusion-related reactions: Stop infusion and permanently discontinue Pemro for severe or life-threatening infusion reactions.Complications of allogeneic HSCT: Allogeneic HSCT after treatment with Pemro: Monitor for hepatic veno-occlusive disease, grade 3-4 acute GVHD including hyperacute GVHD, steroid-requiring febrile syndrome, and other immune-mediated adverse reactions. Transplant-related mortality has occurred. Allogeneic HSCT prior to treatment with Pemro: In patients with a history of allogeneic HSCT, consider the benefit of treatment with Pemro versus the risk of GVHD.Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.Embryo-Fetal toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective method of contraception.

The safety and effectiveness of Pemro in pediatric patients have not been established. No overall differences in safety or effectiveness were observed between elderly patients and younger patients.
