IV infusion: Allow the vial(s) to sit at room temperature for approx 5 minutes prior to infusion preparation. Dilute the required volume with 0.9% NaCl solution for injection or 5% dextrose in water to make a final concentration between 1-4 mg/mL. Mix by gentle inversion; do not shake. When given in combination with nivolumab, infuse the nivolumab dose 1st, followed by the ipilimumab dose on the same day. When administered in combination with nivolumab and platinum-based chemotherapy, infuse the nivolumab dose 1st, followed by the ipilimumab dose, and then the platinum-based chemotherapy dose all on the same day. Use separate infusion bags and filters for each infusion.

This drug may cause tiredness, if affected, do not drive or operate machinery.

Confirm pregnancy status before therapy initiation in females of reproductive potential. Select patients for treatment based on the PD-L1 expression status as clinically indicated. Obtain LFTs at baseline, prior to each dose, and periodically thereafter (monitor more frequently if hepatotoxicity develops); serum chemistries, electrolytes, and ACTH before each dose and regularly during therapy; serum creatinine at baseline and periodically thereafter; TSH, free T₄, and morning cortisol levels at baseline, prior to dose, and as clinically indicated. Monitor for signs and symptoms of cardiac and pulmonary events, infusion reactions, and immune-mediated reactions, including adrenal insufficiency, hypophysitis, thyroid disorders, colitis, motor or sensory neuropathy, dermatologic toxicity, pneumonitis, and hepatitis. Assess for ocular toxicity at baseline, then at 4-8 weeks with further evaluation as clinically necessary. Closely check for evidence of GVHD in patients receiving ipilimumab before or after allogeneic HSCT.

Increased risk of hepatotoxicity (e.g. elevated transaminases) with vemurafenib. Systemic corticosteroids given prior to ipilimumab dose may interfere with the efficacy of ipilimumab; after starting ipilimumab therapy, systemic corticosteroids may be given for immune-related reactions. May increase the risk of gastrointestinal haemorrhage with anticoagulants.

Description:
Mechanism of Action: Ipilimumab is a recombinant, fully human monoclonal antibody antineoplastic agent. It binds to cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), a down-regulator of T-cell activation pathways, thereby inhibiting the interaction of CTLA-4 with its ligands. This activity enhances T-cell activation and proliferation, including the number of reactive T-effector cells which mobilise to provide a direct T-cell immune attack against tumour cells. The inhibition of CTLA-4 may also decrease T- regulatory cell function resulting in increased T-cell responsiveness, including anti-tumour immune response.
Pharmacokinetics:
Excretion: Terminal elimination half-life: 15.4 days.

Store between 2-8°C. Do not freeze. Protect from light. Diluted solutions for infusion are stable for up to 24 hours when stored between 2-8°C or 20-25°C.
