Drug Formulary information is intended for use by healthcare professionals. It is not intended to be medical advice. Some of the information, including information about funding for cancer drugs, does not apply to all patients. Cancer treatment plans are unique to each patient. If you are a patient, please speak with your healthcare team to understand how this information applies to you.

CRBPETOP(PO)+ATEZ

Cancer Type:
Lung, 
Small Cell
Intent: Palliative
Regimen Category: Evidence-informed
Funding:
ODB - General Benefit
    etoposide - oral capsules
New Drug Funding Program
    Atezolizumab - In Combination with Etoposide and Platinum for Extensive-Stage Small Cell Lung Cancer
A - Regimen Name

CRBPETOP(PO)+ATEZ Regimen
CARBOplatin-Etoposide (oral)-Atezolizumab


Disease Site
Lung
Small Cell


Intent
Palliative

Regimen Category
Evidence-informed :

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.

This Regimen Abstract is an abbreviated version of a Regimen Monograph and contains only top level information on usage, dosing, schedule, cycle length and special notes (if available). Information in regimen abstracts is accurate to the extent of the ST-QBP regimen master listings, and has not undergone the full review process of a regimen monograph. Full regimen monographs will be published for each ST-QBP regimen as they are developed.


Rationale and Uses

For first-line treatment of extensive-stage small cell lung cancer, in patients with good performance status


Supplementary Public Funding

etoposide
ODB - General Benefit (etoposide - oral capsules)

atezolizumab
New Drug Funding Program (Atezolizumab - In Combination with Etoposide and Platinum for Extensive-Stage Small Cell Lung Cancer) (NDFP Website )

 
B - Drug Regimen

atezolizumab
1200 mg IV Day 1
CARBOplatin
AUC 5 IV Day 1

Adjust Carboplatin dose to AUC target (using Calvert formula) as outlined in the "Other Notes" section.

etoposide
200* mg /m² PO Days 1 to 3

*Alternative: Etoposide 100 mg/m2 IV day 1 then 200 mg/m2 PO days 2-3

C - Cycle Frequency

REPEAT EVERY 21 DAYS

For a usual total of 4 cycles, followed by atezolizumab maintenance (ATEZ(MNT)), unless disease progression or unacceptable toxicity occurs

 
D - Premedication and Supportive Measures

Antiemetic Regimen:

Moderate + NK1 antagonist (Carboplatin AUC ≥ 5)
No routine prophylaxis for etoposide PO

Also refer to CCO Antiemetic Recommendations.

 

 

 


Pre-medications (prophylaxis for infusion reaction):

Atezolizumab:

  • There is insufficient evidence that routine prophylaxis with premedications reduce infusion reaction (IR) rates.

  • Consider antipyretic and H1-receptor antagonist upon atezolizumab re-challenge.

Carboplatin:

  • There is insufficient evidence that routine prophylaxis with pre-medications reduce infusion reaction (IR) rates.

  • Corticosteroids and H1-receptor antagonists ± H2-receptor antagonists may reduce IR rates for some patients (e.g. gynecological patients with a PFI >12 months or a history of drug allergy who are receiving carboplatin starting from the 7th cycle) but no optimal pre-medication regimen has been established.

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


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


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