nivolumab / relatlimab

( nye-VOL-ue-mab / rel-AT-li-mab )
Funding:
New Drug Funding Program
  • Nivolumab and Relatlimab - Advanced Melanoma (Unresectable or Metastatic Melanoma)
Other Name(s): Opdualag™
Appearance: liquid mixed into larger bags of fluids
A - Drug Name

nivolumab / relatlimab

COMMON TRADE NAME(S):   Opdualag™

 
B - Mechanism of Action and Pharmacokinetics

 

Nivolumab is a human monoclonal antibody (IgG4) that binds to the PD-1 receptor on T-cells, blocking interaction with its ligands, PD-L1 and PD-L2, and preventing PD-1 pathway-mediated inhibition of the tumour immune response. Relatlimab is a human monoclonal antibody (IgG4) that targets the LAG-3 T-cell receptors, blocking its interaction with MHC II and other ligands. This reduces LAG-3 pathway-mediated inhibition of the immune response. Both mechanisms promote T-cell proliferation and cytokine secretion, and the combination of nivolumab / relatlimab results in increased T-cell activation compared to either antibody alone.

 

 
Absorption

After the first dose, relatlimab concentration increased dose proportionally following q4 week dosing of nivolumab / relatlimab.
 

Time to reach steady state

16 weeks (for relatlimab, following q4 week dosing of nivolumab / relatlimab)
 

Metabolism

 

Expected to be degraded into small peptides, amino acids, and small carbohydrates via catabolic pathways
 

 

Elimination
Half-life

~26 days

The most common side effects for nivolumab / relatlimab include fatigue, musculoskeletal pain, rash, pruritus, diarrhea, headache, nausea, vomiting, anorexia, weight loss, cough, dyspnea, hypothyroidism and abdominal pain.

Refer to CCO's Immune Checkpoint Inhibitor Toxicity Management Guideline for detailed descriptions of Immune-related toxicities and their management.

The presentation of adverse effects may be different compared to other anti-cancer agents and early diagnosis and appropriate management are critical.

Immune-related reactions including rash, pneumonitis, colitis, hepatitis, pancreatitis, nephritis, endocrinopathies, meningoencephalitis, and neuropathies have been reported and may be severe or fatal. Onset may vary from days to many months and may occur after treatment has ended.

CMV infection/reactivation has been reported in patients with immune-related colitis who are refractory to corticosteroids. Addition of an alternative immunosuppressive agent or replacement of the corticosteroid therapy should be considered in corticosteroid-refractory immune-related colitis, if other causes are excluded (including CMV infection/reactivation, other viral, bacterial and parasitic etiology).

Immune-mediated endocrinopathies, including hypo or hyperthyroidism, hypophysitis, adrenal insufficiency, and diabetes mellitus, have been reported. Cases of diabetic ketoacidosis have been observed with nivolumab monotherapy and could potentially occur with nivolumab / relatlimab.

Rare cases of SJS and TEN, which may be fatal, have been observed with nivolumab monotherapy and could potentially occur with nivolumab / relatlimab.

 
E - Dosing
 

Refer to protocol by which the patient is being treated.

Screen for hepatitis B virus in all cancer patients starting systemic treatment. Refer to the hepatitis B virus screening and management guideline.

Avoid the use of corticosteroids or immunosuppressants before starting treatment.


Pre-medications (prophylaxis for infusion reaction):

  • Routine pre-medication is not recommended. 

  • May consider pre-medication with antipyretics and H1-receptor antagonists if an IR has occurred in the past.


 
Adults:
 

Intravenous1,2: nivolumab 480 mg / relatlimab 160 mg every 28 days


1Available as a fixed-dose combination product containing nivolumab 12 mg/mL and relatlimab 4 mg/mL.

2Patients must weigh > 40 kg (based on NDFP criteria).
 

Dosage with Toxicity:
 
  • Healthcare professionals should also consult the most recent nivolumab / relatlimab product monograph for additional information.

  • Do not restart nivolumab / relatlimab while the patient is receiving immunosuppressive doses of corticosteroids or other immunosuppressive drugs. Patients receiving immunosuppressive medications (e.g. high-dose corticosteroids) should receive prophylactic antibiotics to prevent opportunistic infections.



Summary of Principles of Management

  • Immune-related adverse effects (irAEs) are different in their presentation, onset and duration compared to conventional chemotherapy. Patient and provider education is essential.

  • Initial irAE presentation can occur months after completion of treatment and affect multiple organs.

  • Dose escalation or reduction is not recommended.

  • If no other cause can be identified (such as infection), any new symptom should be considered immune-related and prompt treatment initiated.

  • Organ-specific system-based toxicity management is recommended.

  • Refer to the CCO guideline for detailed description of Immune-mediated toxicities and their management



Management of Infusion-related reactions:

Also refer to the CCO guideline for detailed description of Management of Cancer Medication-Related Infusion Reactions.

F - Administration Guidelines
 

Nivolumab/relatlimab is not interchangeable with other nivolumab-containing products.

  • Nivolumab / relatlimab may be administered undiluted or diluted with 0.9% Sodium Chloride Injection or D5W.

  • If diluted, the final infusion concentration should range between 3-12 mg/mL for nivolumab and 1-4 mg/mL for relatlimab. Total volume of infusion must not exceed 160 mL.

  • Mix diluted solution by gentle inversion. Do not shake.

  • Infuse IV, do NOT administer as IV push or bolus.
  • Infuse IV over 30 minutes via low protein binding in-line filter (0.2 to 1.2 micrometer).

  • Nivolumab / relatlimab is compatible with ethylvinyl acetate (EVA), polyvinyl chloride (PVC) or polyolefin containers, PVC infusion sets and in-line filters with polyethersulfone (PES), nylon, and polyvinylidene fluoride (PVDF) membranes.

  • Do not infuse concomitantly with other drugs; flush the line with normal saline or D5W after each dose.

  • Store unopened vials in original packaging between 2oC to 8oC. Protect from light.


Also refer to the CCO guideline for detailed description of Management of Cancer Medication-Related Infusion Reactions.


 
 
G - Special Precautions
Contraindications:

 

  • Patients who have a hypersensitivity to nivolumab, relatlimab, or any of their components.

 

Other Warnings/Precautions:

 

  • The pivotal trial excluded patients with certain medical conditions, such as:
    • active brain metastases;
    • those requiring systemic treatment with moderate or high dose corticosteroids or immunosuppressive medicines;
    • uveal melanoma;
    • active autoimmune disease;
    • a history of myocarditis or myositis.
       
  • Nivolumab / relatlimab may increase the risk of rejection in solid organ transplant recipients, or GVHD in patients with prior allogeneic HSCT or GVHD. Assess benefit-risk of nivolumab / relatlimab treatment in these patients.

 


Other Drug Properties:

 

  • Carcinogenicity: Unknown

 

Pregnancy and Lactation:
  • Mutagenicity: Unknown


     

  • Fetotoxicity: Documented in animals

    Nivolumab and relatlimab are IgG4 antibodies; human IgG4 is known to cross the placenta.
     

  • Pregnancy:

    Nivolumab / relatlimab is not recommended for use in pregnancy. Adequate contraception should be used by patients and their partners during treatment, and for at least 5 months after the last dose.
     

  • Excretion into breast milk: Probable

    Immunoglobulins are known to be secreted into breast milk; therefore as a human IgG4 antibody, there is potential for infant exposure to nivolumab / relatlimab via breast milk.
     

  • Breastfeeding:

    Breastfeeding is not recommended during treatment and for at least 5 months after the last dose.
     

  • Fertility effects: Unknown
 
H - Interactions

 

No formal drug interaction studies have been conducted. Nivolumab / relatlimab is unlikely to affect the pharmacokinetics of other drugs.

The use of systemic corticosteroids and other immunosuppressants before starting nivolumab / relatlimab should be avoided because of their potential interference with its activity; however, they can be used after starting nivolumab / relatlimab to treat immune-related adverse reactions. 

Acetaminophen may affect the response to immune checkpoint inhibitors. Further clinical studies are needed to determine the exact mechanism and the appropriate clinical management (Bessede et al, 2022).

 

 
I - Recommended Clinical Monitoring
