Infant Bacterial Therapeutics AB (publ) Interim report January 1 – September 30, 2024

This quarter, IBT completed the global Phase 3 clinical trial “The Connection Study” for the drug candidate IBP-9414. On July 8, we reported that the last patient was treated. On August 30, we reported topline data to the market. Since then, we have continued to analyze the data with our experts. Our conclusion is that our drug candidate IBP-9414 meets the requirements for a pharmaceutical product, meaning we have now documented both the potency and safety of IBP-9414. We see that IBP-9414's safety profile is generally very good, in line with, or in some areas even better, than placebo. When we look at the causes of death in infants, we see a clear reduction in the number of deaths in the cardiopulmonary and gastrointestinal areas after IBP-9414 administration when compared to the children receiving placebo. See figure 1.

If we look at survival as a function of time, we see an clear effect of IBP-9414 after two weeks of treatment. See figure 2 (in attachment) on the Y-axis we see survival and on the X-axis we see the number of days after the first dose is administered.

The overall reduction in mortality of 27% in the IBP-9414 treatment group compared to the placebo group for all preterm infants in the phase 3 study is clinically relevant. In addition, when examining deaths occurring after 14 days of treatment, the relative risk of death is further reduced to 46%. These are fantastic results and as there is no treatment alternative on the market, we at IBT are highly motivated to continue our work to register our product.

After further analysis of the study data, scientifically accepted reasons have emerged as to why it has been difficult to measure our primary endpoints in the study.

There are different pathways for how a product can be registered as a medicine. We will therefore have a meeting with the FDA, which is scheduled for December 2024. Then we will update timetables for the remaining parts of IBP-9414's development work. In parallel with our communication with the authorities, we are ensuring that we can produce large volumes of IBP-9414 to a high standard of quality. We are expanding our supplier network for manufacturing and product analysis. The first commercial batches are planned to be produced in 2025.

Another ongoing activity is the publication of the full results from “The Connection study”, IBT's data from the study will be presented at Hot Topics in Neonatology, December 9,  by Professor Josef Neu who is also the principal investigator of the study. IBT also aims to publish the results in several scientific publications as soon as possible.

On October 25th, IBT was the only company invited to participate in a one-day meeting organized by the US authorities in Washington DC. The purpose of the meeting was to bring together academia, government and industry to discuss the Live Biotheapeutic Products class of drugs and how such products can be developed to prevent NEC. Clinical results for IBP-9414 were also presented during the meeting.

In conclusion, I would like to thank all the staff in the 95 hospitals around the world who collected data for the infants. I would also like to extend a very big thank you to the IBT staff who executed the largest randomized study ever conducted on preterm infants in a very professional manner.  

We now look to the future with confidence, as IBT has no doubt that the results of our phase 3 study demonstrate that premature babies do better with IBP-9414 than without it.
