"Redirecting T-cells to kill cancer cells is a powerful therapeutic approach in the immuno-oncology space. We designed TNB-383B to efficiently kill multiple myeloma cells expressing BCMA and minimize cytokine release from CD3-activated T-cells. This latter attribute is a hallmark of our unique T-cell CD3 engaging therapeutic platform, which is in a number of our follow-on programs and lead clinical candidates," said Roland Buelow, CEO at Teneobio. "Our new class of T-cell engagers were designed to increase the therapeutic window as monotherapies and they may also afford the opportunity for combination treatments of patients."

The TNB-383B Phase 1 study involves a dose-escalation study that will characterize the safety and tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and preliminary anti-cancer activity of intravenous administration of TNB-383B in patients with relapsed or refractory multiple myeloma.

* Non-GAAP Financial Information

See the attached Reconciliation of GAAP to non-GAAP Net Income (Loss) (Unaudited) for an explanation of the amounts excluded to arrive at non-GAAP net income (loss) and related non-GAAP net income (loss) per share amounts for the three and twelve months ended April 30, 2019 and 2018. Non-GAAP financial measures provide investors and management with supplemental measures of operating performance and trends that facilitate comparisons between periods before and after certain items that would not otherwise be apparent on a GAAP basis. Certain unusual or non-recurring items that management does not believe affect the Company’s basic operations do not meet the GAAP definition of unusual or non-recurring items. Non-GAAP net income (loss) and non-GAAP income (loss) per share are not, and should not be viewed as a substitute for similar GAAP items. Champions’ defines non-GAAP dilutive income (loss) per share amounts as non-GAAP net income (loss) divided by the weighted average number of diluted shares outstanding. Champions’ definition of non-GAAP net income (loss) and non-GAAP diluted income (loss) per share may differ from similarly named measures used by others.
