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.
For first-line treatment of extensive stage small cell lung cancer.
REPEAT EVERY 21 DAYS
For a usual total of 4 cycles (unless disease progression or unacceptable toxicity occurs) followed by atezolizumab maintenance (ATEZ(MNT)).
Moderate + NK1 antagonist (Carboplatin AUC ≥ 5) (D1)
Other Supportive Care:
Also refer to CCO Antiemetic Recommendations.
Pre-medications (prophylaxis for infusion reaction):
- There is insufficient evidence that routine prophylaxis with premedications reduce infusion reaction (IR) rates.
- Consider antipyretic and H1-receptor antagonist upon atezolizumab re-challenge.
Also refer to the CCO guideline for detailed description of Management of Cancer Medication-Related Infusion Reactions.
Refer to CCO's Immune Checkpoint Inhibitor Toxicity Management Guideline for detailed descriptions of Immune-related toxicities and their management.

- AUC = product of serum concentration (mg/mL) and time (min)
- GFR (glomerular filtration rate) expressed as measured Creatinine Clearance or estimated from Serum Creatinine (by Cockcroft and Gault method or Jelliffe method)

The format and content of the drug monographs, regimen monographs, appendices and symptom management information contained in the Formulary will change as they are reviewed and revised on a periodic basis. The date of last revision will be visible on each page of the monograph and regimen. Since standards of usage are constantly evolving, it is advised that the Formulary not be used as the sole source of information. It is strongly recommended that original references or product monograph be consulted prior to using a chemotherapy regimen for the first time.
