Corp Presentation - April 2021

Phase 3 Clinical Trial

Narsoplimab for HSCT-TMA

Currently awaiting PDUFA decision which is due on Oct, 17, 2021. Here are the overall response rates for that trial.

The chart below shows the patient survival vs. time for treated patients. Patient survival is the gold standard for the FDA.

Narsoplimab for IgAN

Understanding the Phase 2 trial is crucial to anticipate the success of the current Phase 3 trial.

Here is an overview of the Phase 2 Clinical Trial. The results were very good.

With these results in hand, Omeros worked with the FDA to design the Phase 3 trial, which is currently in progress. The trial design is shown below.

FN Takeaway: Narsoplimab is a pipeline in a drug. It is addressing unmet medical needs in hard to treat conditions.

The share price has gone sideways (with volatilely) for the last several years. Some have criticized management as being to optimistic on their timelines.

It is possible that the upcoming PDUFA results in a CRL from the FDA. The FDA did request additional information from Omeros on May 20. This resulted in a 3 month delay in PDUFA. This is not seen as a negative by management but hopefully the additional info addresses their questions.

Phase 3 for IgAN was put on a complete pause as hospitals focused exclusively on Covid patients. It is possible that a data variation was created which will adversely affect the results.

Phase 3 for IgaN pulls in a much larger group of patients. Anytime this occurs, new variables can be introduced that Phase 2 did not uncover. These variables can cause adverse results resulting in the company not hitting their endpoints.
