STOCKHOLM, SWEDEN – December 9, 2019. Karolinska Development (Nasdaq Stockholm: KDEV) announces today that its portfolio company Aprea Therapeutics presented results from two Phase Ib/II clinical trials at the 2019 American Society of Hematology (ASH) Annual Meeting in Orlando. Both trials evaluated the safety and efficacy of APR-246 in combination with azacitidine for the treatment of TP53 mutated Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML).

Aprea Therapeutics is a biopharmaceutical company focused on developing novel cancer therapeutics that reactivate mutant tumor suppressor protein p53. Mutations of the p53 gene occur in around 50% of all human tumors and are often associated with resistance to anticancer drugs and poor overall survival. APR-246 is a small molecule that has demonstrated reactivation of mutant and inactivated p53 protein. Today Aprea Therapeutics presented results at the 2019 ASH Annual Meeting from two Phase Ib/II studies of APR-246 in combination with azacitidine for the treatment of TP53 mutated MDS and AML.

In one of the presented studies, as of the data cutoff, the overall response rate (ORR) in 33 evaluable MDS patients was 88%, with a 61% complete remission (CR) rate, by International Working Group criteria. The median duration of response was 8.4 months, with 7.3 months median duration of CR in evaluable MDS patients. Seventeen (52%) evaluable MDS patients discontinued therapy to pursue stem cell transplant. Median overall survival (OS) for all enrolled patients (n=55) was 10.8 months. Median OS in responding patients versus non-responders was 13.7 vs. 3.9 months.

In the other study, as of the data cutoff, ORR in 24 evaluable MDS patients was 74%, with a 66% complete remission rate, based on International Working Group criteria. With a median duration of follow-up of 6.4 months, the median OS for all enrolled patients (n=53) had not been reached. In addition, all responding patients were alive at data cutoff. Relative to baseline, mutant TP53 variant allele frequency (VAF) was significantly decreased in responding patients and undetectable in all patients who achieved a CR.

A pivotal Phase 3 clinical trial of APR-246 and azacitidine for frontline treatment of TP53 mutant MDS is ongoing. APR-246 has received Orphan Drug and Fast Track designations from the FDA for MDS, and Orphan Drug designation from the EMA for MDS, AML and ovarian cancer.
