Large unmet need: • According to National Center for PTSD, about 60% of men and 50% of women in the US are exposed least one traumatic experience in their lives 1 • In the US alone, one - third of emergency department visits (40 - 50 million patients per year) are for evaluation after trauma exposures 2 Current standard of care: • No medications are currently available at or near the point of care to treat patients suffering from acute traumatic events and support long - term health 1 National Center for PTSD.

IMMUNOLOGY PORTFOLIO Non - Human Primate Bone Marrow Transplantation Dr. Leslie Kean 1 , Boston Children’s Hospital/Dana Farber Studying TNX - 1500 in combination with other drugs for preventing rejection and graft versus host disease (GvHD) in bone marrow transplant 2 ‒ Hematopoietic Stem Cell Transplantation (HCT) from unrelated donors is a component of the treatment protocol for several hematologic malignancies ‒ GvHD complicates treatment and limits the success of engraftment after HCT ‒ To be successful, the post - HCT indication requires prolonged engraftment. ‒ GvHD remains one of the most severe complications associated with HCT. For myeloablative MHC - haploidentical HCT, the risk of GvHD is substantial, and with the most severe form of acute GvHD, as many as half of patients can die from this disease. For these high - risk transplants, there is no fully effective GvHD prevention strategy. ‒ The primary objective of the preclinical research study is to study the activity of TNX - 1500 administered prophylactically to modify GvHD progression in animals after HCT to support an Investigational New Drug (IND) application for human studies Prof. Kean is a leader in the field of NHP bone marrow transplants ‒ Unique model of haplo - identical animals 3 1 The principal investigator is Leslie S.
