Comment from the CEO – Progress according to plan


The second quarter began with an intense period for Stayble. In April, we successfully completed our rights issue, released interim data from the ongoing Phase IIb study, and made two strategically important recruitments. We are now well positioned for a continually eventful 2023.

At the start of the year, we received the approval to initiate the first clinical study with the drug candidate STA363 for herniated discs. This means that we now have two indications for STA363, enhancing the project’s value and diversifying risk. The herniated disc study is ongoing with clinics already initiated, and we look forward to treating the first patients in Q3, as previously communicated. The Phase Ib study focuses primarily on investigating safety and tolerability, but also volume changes of the disc will be measured. This study involves patients experiencing pain due to herniated discs in the lumbar spine. Previous research has demonstrated the safety of the drug candidate STA363 through injection into patients’ discs with degenerative disc disease. Building on the insights gained from prior Phase Ib and Phase IIb studies involving patients with degenerative disc disease, we anticipate an efficient process leading to results by the end of the first half of 2024.

Earlier this year (February), Stayble was able to secure all critical data to evaluate the primary endpoint of the Phase IIb study. Currently, over 90% of patients have completed the 12-month follow-up, significantly reducing the operational risk associated with the inability to draw conclusions from this follow-up period. The study is proceeding according to plan and we are approaching the time for obtaining top-line data, which is planned for the fourth quarter of this year.

Significant progress has been made through partnership efforts during the second quarter. Our participation at the BIO International Convention in Boston led to fruitful discussions. We have established several promising contacts with global companies with the necessary capacity to support a clinical phase III program with STA363, a regulatory process and future commercialization. During the meeting, we noted an increased interest in projects focused on long-term pain and in the outcome of our phase IIb study, where even a moderate effect on the pain scale is seen as highly interesting. The response we have received, together with the fact that our drug candidate STA363 now covers two indications, means that we look forward to further interesting discussions.

In summary, this quarter marks a period of significant progress for the Company. With the capital raised from the rights issue, we can drive our ongoing studies at the desired pace. I extend my gratitude to our existing and new shareholders for your continued support. Together, we look forward to continuing this exciting journey toward alleviating back pain and making a meaningful impact in people’s lives.
