On April 22, 2020, the Company announced that it plans to report in mid-2020 interim results from the dose-optimization part of its ongoing Phase 1b/2 clinical trial of ALRN-6924 in patients with small cell lung cancer, or SCLC, being treated with topotecan. The Company is evaluating ALRN-6924 in this trial as an agent to protect cancer patients against chemotherapy-induced toxicity, a concept known as chemoprotection, and is seeking to identify a dose and dosing schedule of ALRN-6924 administration to reduce severe anemia, neutropenia and thrombocytopenia resulting from topotecan.

In the dose-optimization part of the trial, topotecan is administered daily on days 1 through 5 of every 21-day treatment cycle, and ALRN-6924 is administered 24 hours before each dose of topotecan (on days 0 through 4 every 21 days). The Company plans to commence the schedule optimization part of the trial in June 2020. In this part of the trial, the Company plans to evaluate ALRN-6924 at two dose levels in a total of 20 patients. In this part of the trial, ALRN-6924 will be dosed six hours before each dose of topotecan (on days 1 through 5 of every 21-day treatment cycle).

The Company currently plans to report top-line final data for both the dose optimization and schedule optimization parts of the trial in the fourth quarter of 2020. The Company expects that these results will determine a recommended ALRN-6924 dose and schedule for subsequent trials.
