Throwback by JCO! Docetaxel vs Pemetrexed in 2L NSCLC showed similar OS/PFS outcomes, but Pemetrexed was tolerated better particularly in terms of myelosuppression. Pemetrexed was active in squamous cancers as well.
To compare the efficacy and toxicity of pemetrexed versus docetaxel in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with chemotherapy.
Eligible patients had a performance status 0 to 2, previous treatment with one prior chemotherapy regimen for advanced NSCLC, and adequate organ function. Patients received pemetrexed 500 mg/m2 intravenously (IV) day 1 with vitamin B12, folic acid, and dexamethasone or docetaxel 75 mg/m2 IV day 1 with dexamethasone every 21 days. The primary end point was overall survival.
Five hundred seventy-one patients were randomly assigned. Overall response rates were 9.1% and 8.8% (analysis of variance P = .105) for pemetrexed and docetaxel, respectively. Median progression-free survival was 2.9 months for each arm, and median survival time was 8.3 versus 7.9 months (P = not significant) for pemetrexed and docetaxel, respectively. The 1-year survival rate for each arm was 29.7%. Patients receiving docetaxel were more likely to have grade 3 or 4 neutropenia (40.2% v 5.3%; P < .001), febrile neutropenia (12.7% v 1.9%; P < .001), neutropenia with infections (3.3% v 0.0%; P = .004), hospitalizations for neutropenic fever (13.4% v 1.5%; P < .001), hospitalizations due to other drug related adverse events (10.5% v 6.4%; P = .092), use of granulocyte colony-stimulating factor support (19.2% v 2.6%, P < .001) and all grade alopecia (37.7% v 6.4%; P < .001) compared with patients receiving pemetrexed.
Treatment with pemetrexed resulted in clinically equivalent efficacy outcomes, but with significantly fewer side effects compared with docetaxel in the second-line treatment of patients with advanced NSCLC and should be considered a standard treatment option for second-line NSCLC when available.
Superior to osi (23 vs 16 progression-free survival). This is more toxic though, but seems manageable. Could this be a new first line standard of care? Also, this includes brain penetration data.
Adding SBRT improves local control and disease progression in the brain but not overall survival. Do the radiation oncologists have input? Is it worth it to control symptoms?
Neoadjuvant Osimertinib did not have a significant impact on major pathologic response and there were no ypCR’s after a median of ~8 weeks of therapy. I do think this shows a measurable response, enough such that I would consider Osi in a patient with “borderline resectable” disease.
Osimertinib in adjuvant, now after chemotherapy and radiation, next… Neoadjuvant??? Trials are ongoing.
This is here till progression.
Failed? Numerical overall survival (OS) benefit for sacituzumab vs docetaxol, but not statistically significant. Better tolerated, also overall survival (OS) noticed more in patients who did not respond to antiPDL-1 therapy.
