Side effects and precautions of Talatumumab

Talatuzumab is a bispecific antibody drug that targets and eliminates cancer cells by activating T cells. The drug has shown significant efficacy in clinical trials, but it is also accompanied by potential adverse reactions such as cytokine release syndrome (CRS). Talatumumab should be used correctly, medication precautions should be strictly followed, and medication restrictions for special groups should be understood. This article will discuss in detail the side effects of talatumumab, precautions when using it, and medication recommendations for special groups.

Side effects of talatumumab

is an immunotherapy drug. Its side effects are mainly related to activation of the immune system, and some reactions may be serious.

Cytokine release syndrome (CRS)

CRS is the most common adverse reaction of talatumumab, which manifests as fever, hypotension, fatigue, tachycardia, etc. In severe cases, it can lead to cardiac insufficiency, respiratory distress syndrome or multiple organ failure. Escalating dosing regimens may reduce incidence and severity.

Neurotoxicity

Some patients may develop immune effector cell-associated neurotoxic syndrome (ICANS), with symptoms including confusion, drowsiness, and disorientation. Neurotoxicity can occur simultaneously with CRS or alone, and timely intervention is required.

Hematologic abnormalities

Talatuzumab may cause neutropenia, thrombocytopenia, and anemia. Complete blood cell counts need to be monitored regularly during treatment, and medication needs to be suspended if severe cytopenias occur.

Understanding the clinical manifestations of these side effects can help medical staff identify and take intervention measures in a timely manner.

Precautions for talatumumab

The following precautions must be strictly observed when using talatumumab.

Administration environment requirements

Talatuzumab must be administered in a medical institution equipped with CRS monitoring and first aid conditions. Patients need to be monitored continuously for 22-24 hours on Days 1 and 8 of Cycle 1, and patients are advised to remain near a medical facility for 48 hours after infusion.

Pretreatment and concomitant medication

Pretreatment drugs such as dexamethasone need to be used before administration to reduce the risk of CRS. Normal saline should be infused intravenously immediately after the infusion to promote drug metabolism and excretion.

Monitoring and Dose Adjustment

Assess complete blood count and liver function before each dose. Depending on the severity of adverse reactions, it may be necessary to suspend or permanently discontinue the drug and provide appropriate supportive care.

Strictly adhering to these precautions can minimize treatment risks and maximize patient benefits.

Usage of talatumumab in special groups

Special groups need to pay special attention to potential risks when using talatumumab, and adjust the medication regimen according to individual conditions.

Pregnant and lactating women

Talatuzumab may cause harm to the fetus and is contraindicated in pregnant women. Breastfeeding women need to suspend breastfeeding during treatment and can resume 2 months after the last dose.

Patients with hepatic and renal insufficiency

Patients with mild to moderate hepatic and renal impairment do not need to adjust the dose, but patients with severe renal insufficiency (eGFR<30 mL/min) or moderate to severe hepatic impairment have limited medication data and should be used with caution.

Elderly patients

Elderly patients over 65 years old do not need to adjust the dose, but due to limited clinical data, adverse reactions need to be closely monitored during medication.

Before taking medication, the doctor will formulate an individualized medication plan for special groups, and patients should strictly follow the doctor's instructions.
