Infant Bacterial Therapeutics AB (publ) Interim Ma

Message from the CEO

During the past year, IBT passed the most important milestones in the company's history. The company's drug candidate, IBP-9414, which we believe will prevent necrotizing enterocolitis, has demonstrated similar safety and tolerability profile in a Phase II study focused on safety and tolerability when IBP-9414 was administered in comparison with placebo.

During the spring of 2018 we ensured that we now have the resources needed to complete the Pivotal Phase III study, that we chose to call "The Connection Study". We expect to be able to announce "first patient in" to this pivotal trial in the near term. The last pieces of the puzzle in relation to our Clinical Research Organization (CRO) and Clinical Trial Material (CTM) vendors are also soon in place.

As previously communicated, IBT has applied for listing on Nasdaq's main list. We will meet all requirements for IBT to be approved for the main list. If nothing unanticipated occurs, I expect IBT to be approved on the main list during the third quarter of 2018.

We have also established an Advisory Board to aid in evaluating other new development projects. Here, IBT will be restrictive with focus on projects that can be taken to market and which satisfy an unmet medical need on parity with IBP-9414. I will return with more information about and when we identify additional valuable projects.

In summary, everything is progressing according to plan and we are looking forward to getting the study started and listing change approved in the near future.

Staffan Strömberg, Chief Executive Officer
