Karolinska Development's portfolio company PharmNovo receives approval to initiate a phase 2a trial of its drug candidate PN6047 in Spain
STOCKHOLM, SWEDEN – October 9, 2025. Karolinska Development AB (Nasdaq Stockholm: KDEV) today announces that its portfolio company PharmNovo has received approval from the Spanish regulatory authorities to initiate a phase 2a clinical trial of its drug candidate, PN6047, being developed as a treatment for neuropathic pain. The trial will be conducted in the EU, but has been fully aligned with the requirements defined by the U.S. Food and Drug Administration (FDA), earlier this year.
The Spanish Health Authorities have approved PharmNovo’s clinical trial application (CTA) to conduct a phase 2a clinical trial investigating the safety and efficacy of the lead candidate, PN6047, in patients with neuropathic pain. The trial will be initiated in Spain, but PharmNovo plans to also submit applications to expand the study to Czech Republic and Poland. Provided that the necessary funding for the implementation of the study is secured, patient enrolment is expected to start by mid-2026.
In January 2025, PharmNovo successfully completed a pre-IND Type B meeting with the U.S. Food and Drug Administration (FDA). The current study is fully aligned with the FDA requirements defined during that meeting, and an IND application is currently being compiled.
"It is encouraging to see that PharmNovo is making progress in the clinical development of the innovative pain treatment PN6047. The drug candidate has potential as a new treatment for severe pain without giving rise to the addiction problem associated with traditional opioids, which is posing a major societal problem today," said Viktor Drvota, CEO of Karolinska Development.
PharmNovo’s most advanced drug candidate, PN6047, is a selective delta-opioid receptor agonist (DORA) being developed as a new treatment for complex pain conditions.
Karolinska Development's ownership in PharmNovo amounts to 20 percent.
