Tevimbra (tislelizumab-jsgr)

Drug Overview

Tevimbra is an immune checkpoint inhibitor (PD-1 blocker) used to treat unresectable or metastatic esophageal squamous cell carcinoma (ESCC) after prior systemic chemotherapy without PD-(L)1 inhibitors.

Mechanism of Action:

  • Blocks PD-1 on T-cells, preventing cancer cells from evading immune detection.
  • Enhances T-cell-mediated tumor destruction.

Dosage & Administration:

  • 200 mg IV infusion every 3 weeks until disease progression or intolerable toxicity.
  • First infusion: Administer over 60 minutes.
  • Subsequent infusions (if tolerated): May reduce to 30 minutes.

Patient Education Before Administration

  1. Pre-Infusion Assessment:
    • Verify allergies, medical history (autoimmune disorders, organ transplants, pregnancy).
    • Confirm pregnancy status (avoid pregnancy for ≥4 months post-treatment).
    • Review concurrent medications (risk of immune-mediated interactions).
  2. Infusion Preparation:
    • Inspect solution: Should be clear to slightly opalescent, colorless to pale yellow.
  3. Patient Instructions:
    • Wear comfortable clothing (easy IV access).
    • Hydrate well before the appointment.
    • Arrange transportation (fatigue/dizziness may occur post-infusion).

Administration Guidelines

  1. IV Setup:
    • Use 0.9% NaCl or 5% dextrose as diluent if needed.
    • Administer via IV line with a 0.2–5 micron filter.
  2. Infusion Monitoring:
    • First dose: Monitor for hypersensitivity reactions (flushing, dyspnea, rash).
    • Vital signs: Check before, during, and after infusion.
  3. Rate Adjustments:
    • If mild reaction (Grade 1-2): Pause infusion, manage symptoms, resume at slower rate.
    • If severe reaction (Grade 3-4): Stop infusion permanently.

Managing Side Effects & Reactions

Common Side Effects:

  • Fatigue, rash, diarrhea, immune-mediated reactions (colitis, pneumonitis, hepatitis).

Severe Immune-Mediated Reactions:

  • Pneumonitis: Monitor for dyspnea, hypoxia. Withhold Tevimbra if Grade 3, discontinue if Grade 4.
  • Hepatitis: Check LFTs (AST/ALT elevation). Hold for Grade 3, discontinue for Grade 4.
  • Colitis: Assess for diarrhea, abdominal pain. Requires corticosteroids if severe.

Infusion-Related Reactions (IRRs):

  • Symptoms: Fever, chills, hypotension, flushing.
  • Management:
    • Mild IRR: Slow infusion rate, administer antihistamines/steroids.
    • Severe IRR: Stop infusion, initiate emergency protocols (epinephrine if anaphylaxis).

Post-Infusion Monitoring & Education

  1. Follow-Up:
    • Lab monitoring: CBC, LFTs, thyroid function (immune-mediated effects).
    • Symptom tracking: Report persistent fever, diarrhea, or neurological changes.
  2. Patient Discharge Instructions:
    • Avoid live vaccines during treatment.
    • Watch for delayed immune reactions (may occur weeks later).
    • Seek emergency care for severe symptoms (chest pain, difficulty breathing).
  3. Nursing Documentation:
  • Record infusion start/stop time, vital signs, adverse reactions, and patient tolerance.
