Bioblast Pharma Reports Second Quarter 2017 Financial Results

Tel Aviv, Israel, – August 4, 2017 – Bioblast Pharma Ltd. (NasdaqCM: ORPN), a clinical-stage, orphan disease-focused biotechnology company, today announced financial results for the second quarter ended June 30, 2017.

Second Quarter 2017 Financial Results and Cash Position

· R&D Expenses: Research and development expenses were $0.9 million for the quarter ended June 30, 2017, compared to $1.9 million for the same period in 2016. The decrease was primarily related to reduced clinical trial related activities, specifically as our planned Phase 2b clinical study in Ocular Pharyngeal Muscular Dystrophy patients has not been initiated.

· Pre-Commercial Expenses: Pre-commercial expenses were $0.1 million for the quarter ended June 30, 2017, compared to $0.1 million for the same period in 2016.

· G&A Expenses: General and administrative expenses were $0.7 million for the quarter ended June 30, 2017, compared to $1.7 million for the same period in 2016. The decrease was primarily related to downsizing of the management team, which took effect primarily in the second quarter of 2016, offset by costs related to a terminated securities offering, announced on April 6, 2017.

· Net Loss: For the quarter ended June 30, 2017, net loss attributable to holders of ordinary shares was ($1.6) million, or ($0.10) per basic and diluted share, as compared to a net loss of ($3.7) million, or ($0.22) per share, for the same period in 2016.

· Cash Position: Cash, cash equivalents and short-term bank deposits as of June 30, 2017, were $5.2 million, compared to $7.1 million as of March 31, 2017, primarily reflecting our second quarter operating expenditures.

Post Second Quarter 2017 Activities

· As part of the continuing effort to reduce expenditures, the Company announced that Colin Foster and Ralf Rosskamp, MD, have submitted their resignations as members of the Board of Directors, effective August 31, 2017.

· The number of employees has been reduced to three, including the Chief Executive Officer, the Chief Medical Officer and the Chief Financial Officer, all of whom are working to assist JSB-Partners, which is the Company’s exclusive advisor to find a third party for partnership or merger opportunities.

· In addition, a comprehensive review of operations has identified expenses that have been eliminated or cut back across-the-board.
