Krakow, Poland – 08 September 2021 – Ryvu Therapeutics (WSE:RVU) reported today its 2021 semiannual financial results and provided a corporate update.

“The first half of 2021 was a time to remember for Ryvu. After some initial setbacks we reported major developments in our both clinical programs confirming single agent efficacy of RVU120 and SEL24/MEN1703, and we entered H2 2021 with a solid foundation for the further advancement of our pipeline” – commented Pawel Przewiezlikowski, Chief Executive Officer of Ryvu.

“In April 2021 the FDA placed a partial clinical hold on our Phase Ib clinical trial of RVU120 in AML/HR-MDS patients which was then successfully lifted in July. We also received a full approval to initiate Phase I/II trial with RVU120 in solid tumors, and the first patient has been already dosed in that trial. EHA 2021 Congress was an exceptional one for us, as we got to present the first positive Phase I data for RVU120, along with the positive follow-up Phase II data presented for SEL24/MEN1703 by our partner, Menarini. We also enjoyed the first ever oral presentation of RVU120 at a major oncology conference, demonstrating its potential in promoting cell differentiation. Additionally, we welcomed Vatnak Vat-Ho, our new Chief Business Officer, on board” – adds Przewiezlikowski.

 

Recent Achievements

• First patient dosed in Phase I/II study of RVU120 (SEL120) in patients with relapsed/refractory (R/R) metastatic or advanced solid tumors

On August 25, Ryvu announced that the first patient was dosed in the Phase I/II clinical trial investigating RVU120 in relapsed/refractory metastatic or advanced solid tumors. The single-agent, open-label Phase I/II trial is currently enrolling patients in Poland, and site expansion to Spain is in progress.

• Initial positive clinical data presented at the EHA Virtual Congress in June 2021; RVU120 Phase Ib study in AML and high-risk MDS patients resumed enrollment;

The initial safety and efficacy data from the first four cohorts in the trial were presented at the Virtual EHA Congress on June 11, 2021. RVU120 demonstrated acceptable safety profile and two clinically relevant responses were observed in the first five AML and high-risk MDS patients treated: one complete response (CR) and one erythroid response. During the partial clinical hold, two patients continued on RVU120 treatment, and one MDS patients currently remains on study after more than 12 months of treatment with RVU120.

On July 14, Ryvu announced that the U.S. Food and Drug Administration lifted a partial clinical hold, previously announced on April 8, 2021, on the first-in-human (FIH) Phase Ib, dose escalation clinical trial of RVU120 in patients with R/R acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (high-risk MDS), being conducted in the United States.

Three out of five AML patients harboring IDH mutations treated at 75-125 mg achieved CR/CRi. A follow-up study in IDH-mutated patients was initiated by Menarini in July 2021.
