Les renseignements du Formulaire de médicaments s’adressent aux professionnels de la santé. Il ne s’agit pas d’un avis médical. Certains des renseignements, y compris ceux sur le financement des médicaments anticancéreux, ne s’appliquent pas à tous les patients. Les plans de traitement du cancer sont propres à chaque patient. Si vous êtes un patient, veuillez parler avec votre équipe soignante pour comprendre comment ces renseignements s’appliquent à vous.
DURV(MNT)
Regimen is considered appropriate as part of the standard care of patients; meaningfully improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR). Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.

(Durvalumab - In Combination with Etoposide and Platinum for Extensive-Stage Small Cell Lung Cancer)
(NDFP Website
)
After 4 cycles of etoposide and platinum chemotherapy1:
| durvalumab | 1500* mg | IV | Day 1 |
1Including CISPETOP+DURV, CISPETOP(PO)+DURV, CRBPETOP+DURV, or CRBPETOP(PO)+DURV
*For patients with body weight ≤ 30 kg, give durvalumab 20 mg/kg, until weight increases to > 30 kg.
Minimal
- Also refer to CCO Antiemetic Recommendations.
Premedication (prophylaxis for infusion reactions):
- Consider pre-medication in patients with prior infusion related reactions.
Doses should be modified according to the protocol by which the patient is being treated.
Avoid the use of corticosteroids or immunosuppressants before starting treatment.
Dosage with toxicity
- Healthcare professionals should also consult the most recent durvalumab product monograph for additional information.
-
Dose reductions are not recommended for durvalumab. Doses may be delayed or discontinued based on toxicity.
-
Hold durvalumab for severe infections; manage symptoms and treat with anti-infectives.
Summary of Principles of Management of Immune-Related Adverse Effects (irAEs)
-
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 CCO's Immune Checkpoint Inhibitor Toxicity Management Guideline for detailed descriptions of Immune-related toxicities and their management.
Non-immune-related toxicity
| Severity | Action |
| Grade 2 or 3 | Hold until ≤ Grade 1 or baseline |
| Grade 4 | Discontinue* |
*Decision to discontinue for lab abnormalities should be based on signs/ symptoms and clinical judgement.
Management of Infusion related Reactions
| Severity | Action |
| Grade 1 or 2 |
Interrupt or slow the rate of infusion by 50%. Consider pre-medications prior to subsequent infusions. |
| Grade 3 or 4 | Discontinue |
Hepatic Impairment
Refer to CCO's Immune Checkpoint Inhibitor Toxicity Management Guideline for detailed descriptions for immune-related hepatitis management.
| Hepatic Impairment | Durvalumab Dose |
|
Mild (bilirubin ≤ ULN and AST > ULN or |
No dosage adjustment is required |
| Moderate (bilirubin >1.5 to 3 x ULN and any AST) | |
|
Severe (bilirubin >3 x ULN and any AST) |
No data |
Renal Impairment
Refer to CCO's Immune Checkpoint Inhibitor Toxicity Management Guideline for detailed descriptions for immune-related nephritis management.
| Creatinine Clearance (mL/min) | Durvalumab Dose |
| ≥ 30 | No dosage adjustment is required |
| < 30 | No data |
Dosage in the Elderly
No dosage adjustment is required for patients aged 65 and older. No overall differences in safety or efficacy were reported between patients ≥ 65 years of age and younger patients.
Refer to durvalumab drug monograph(s) for additional details of adverse effects.
|
Less common (10-24%) |
Uncommon (< 10%), but may be severe or life-threatening |
|
|
Refer to durvalumab drug monograph(s) for additional details.
No formal pharmacokinetic drug-drug interaction studies have been conducted.
Use of systemic corticosteroids or immunosuppressants should be avoided prior to starting durvalumab because of potential interference with efficacy. They can be used to treat immune-mediated reactions after starting the drug.
Refer to durvalumab drug monograph(s) for additional details.
Administration
- Administer by IV infusion over 60 minutes using a sterile, low-protein binding 0.2-0.22 micron in-line filter.
- Durvalumab is supplied as a single-use, preservative-free vial.
- Visually inspect the vial for particulates and discolouration prior to dilution. Undiluted solution should be clear to opalescent and colorless to slightly yellow.
- Using aseptic technique, withdraw the required drug volume and transfer to an IV bag of NS or D5W to a final concentration of 1 to 15 mg/mL.
- Mix by gentle inversion; do not shake.
- Do not co-administer with other drugs; flush line after each dose.
- Store unopened drug vials under refrigeration (2-8oC) in the original package.
- Protect from light and do not freeze.
Contraindications
-
Patients who have a hypersensitivity to this drug or any of its components.
Warnings/Precautions
- Use with caution and monitor closely in patients with pre-existing conditions such as colitis, hepatic impairment, respiratory or endocrine disorders, such as hypo or hyperthyroidism or diabetes mellitus.
- Some clinical trials excluded patients with a history of immunodeficiency; medical conditions that required systemic immunosuppression; history of severe immune-mediated adverse reactions; history of allogeneic organ transplantation; prior exposure to immune checkpoint inhibitors; history of chest radiation therapy; untreated CNS metastases; HIV; active tuberculosis, hepatitis B or C infection, or patients who received live attenuated vaccine(s) within 30 days before or after starting durvalumab.
- Use caution when driving or operating machinery as patients may experience adverse effects affecting their ability to concentrate or react.
Pregnancy/Lactation
