Social Analysis

  • 10 LinkedIn posts, 3 Facebook posts and 1 tweet collectively highlighted that the FDA has granted priority review to Sacituzumab Govitecan-hziy (Trodelvy) for patients with unresectable locally advanced or metastatic HR–positive, HER2-negative breast cancer who have previously received endocrine-based therapy and at least 2 additional systemic therapies in the metastatic setting. The priority review is based on results from the phase 3 TROPiCS-02 trial (NCT03901339)
  • 1 tweet and 1 Facebook post discussed the second interim analysis results of OlympiA clinical trial (NCT02032823) and mentioned that, with 3.5 years of median follow-up, OlympiA demonstrated statistically significant improvement in overall survival (OS) with adjuvant olaparib compared with placebo for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 and high-risk, HER2-negative early breast cancer. The findings were published in the Annals of Oncology journal on 10th October 2022
  • 1 LinkedIn post highlighted the result of clinical trial “Real-World Effectiveness of Palbociclib in Combination With an Aromatase Inhibitor” (NCT05361655) sponsored by Pfizer.                          The post mentioned that palbociclib demonstrated a median overall survival (OS) of 49.1 months which is significantly longer compared to aromatase             inhibitor recipients, who showed OS of 43.2 months. The post also highlighted   that the progression-free survival (PFS) is 19.3 months and 13.9 months with palbociclib and aromatase inhibitor, respectively. These findings were published in NPJ breast cancer journal on 11th October 2022.
