Dr. Anjan Patel's Thoughts

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.

PURPOSE

To compare the efficacy and toxicity of pemetrexed versus docetaxel in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with chemotherapy.

PATIENTS AND METHODS

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.

RESULTS

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.

CONCLUSION

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.

First-Line Sunvozertinib in NSCLC with EGFR Exon 20 Insertion Mutations

Progression-free survival (PFS) was higher in the Sun group vs chemotherapy, 10.3 m vs 7.5 m with HR of .65 with higher responses (58.9% vs 31.1%) diarrhea high CK and anemia were the most common side effects. The issue is that amivan was not part of treatment and compared to chemotherapy ami in addition to chemotherapy had 11m PFS also in this trial few had brain mets so no evaluation for CNS protection or treatment. But an oral agent in patients who don’t want to come to the office often.

Selpercatinib in Early-Stage RET Fusion–Positive Non–Small-Cell Lung Cancer

109 patients with stage II or IIIA disease, 2-year investigator-assessed event-free survival was 92% with selpercatinib and 61% with placebo (HR for disease recurrence, progression, or death, 0.17 P<0.001). Patients with stage IB, II, or IIIA non–small-cell lung cancer (NSCLC), event-free survival at 2 years was 94% with selpercatinib and 70% with placebo. Genomic testing is expanding now for early stage NSCLC. More study in the adjuvant setting showing promise with targeted therapy.

Ensartinib in Resected ALK-Positive Non–Small-Cell Lung Cancer

It seems the old cliche of more drugs than patients is becoming true for most providers here. The data needs to mature further here but likely this will be another option for Anaplastic lymphoma kinase (ALK)+ non–small-cell lung cancer (NSCLC) patients in the adjuvant setting. It does look like CNS protection benefits are meaningful as well.

Ivonescimab plus chemotherapy versus tislelizumab plus chemotherapy in advanced squamous non-small-cell lung cancer (HARMONi-6): interim overall survival analysis of a randomised, double-blind, phase 3 trial in China

The median overall survival (OS) was 27·9 months with ivonescimab versus 23·7 months with tis.

Sacituzumab tirumotecan plus pembrolizumab versus pembrolizumab in PD-L1-positive advanced non-small-cell lung cancer (OptiTROP-Lung05): interim analysis of a randomised, open-label, phase 3 trial

Median progression-free survival was significantly longer with sac-TMT plus pembrolizumab than with pembrolizumab alone (not reached vs 5·7 m) this is regardless of PDL-1 expression (1-49 or >50).
