Aileron Stock Is Trading Lower After Data Presentation For Chemoprotective Agent - Aileron Therapeutics (NASDAQ:ALRN)

Aileron Therapeutics Inc ALRN presented new clinical data at the European Society of Medical Oncology (ESMO21) Virtual Congress 2021 for ALRN-6924, a chemoprotective agent.
Aileron is developing ALRN-6924 to selectively protect healthy cells in patients with cancers that harbor p53 mutations to reduce or eliminate chemotherapy-induced side effects while preserving chemotherapy's attack on cancer cells.
The Company presented final results from Phase 1b trial of ALRN-6924 in patients with small-cell lung cancer (SCLC) receiving second-line topotecan treatment.
The data demonstrated ALRN-6924's 'triple-play efficacy' for reducing neutropenia, thrombocytopenia, anemia, and a reduction of platelet and red blood cell transfusions compared to historical controls.
While chemoprotection effects were observed across all ALRN-6924 dose levels, the 0.3 mg/kg ALRN 6924 dose level given 24 hours before topotecan demonstrated the most robust chemoprotection results.
None of the patients treated at the 0.3 mg/kg 24 hour ALRN-6924 dose level had a related serious adverse event (SAE).
At the 0.3 mg/kg 24 hour ALRN-6924 dose level, one patient required a red blood cell transfusion and a platelet transfusion.
In the topotecan plus placebo arm of a third-party Phase 2 trial, in SCLC patients receiving topotecan (N=28), 41% and 31% received red blood cell and platelet transfusions, respectively.
Price Action: ALRN stock is down 6.52% at $1.08 during the market session on the last check Thursday.
