CBIO Catalyst Biosciences Inc

-- Enrollment into Phase 1/2 trial of Factor IX SQ candidate CB 2679d is ongoing; trial is on track to announce interim results by year-end --

Catalyst Biosciences, Inc. (NASDAQ:CBIO), today announced financial results for the second quarter ended June 30, 2017 and provided a corporate update.

Recent Milestones: Factor IX SQ CB 2679d (also known as ISU304)

• Initiated and completed dosing of first patient cohort in Phase 1/2 clinical trial of subcutaneous (SQ) CB 2679d in individuals with hemophilia B;
• Received a $0.7M milestone payment from Catalyst’s collaborator, ISU Abxis, for initiation of the Phase 1/2 clinical trial;
• Presented positive preclinical results at an international hemophilia meeting (ISTH) that demonstrate the ability to normalize Factor IX levels in a model of hemophilia B with daily SQ dosing; and
• Received Orphan Medicine Designation from the European Commission for the treatment of individuals with hemophilia B with SQ CB 2679d.

Recent Milestones: Factor VIIa/marzeptacog alfa (activated)

• Presented positive preclinical results at ISTH of Catalyst’s subcutaneously administered Factor VIIa, marzeptacog alfa (activated), that support the initiation of a Phase 2/3 clinical trial to evaluate subcutaneous dosing as prophylaxis for individuals with hemophilia and an inhibitor.

“We made significant progress in both our clinical programs and strengthened our balance sheet in the second quarter” said Nassim Usman, Ph.D., Catalyst’s President and Chief Executive Officer. “The Factor IX program was initiated on schedule and we expect to report interim results from the Phase 1/2 subcutaneous dosing study in individuals with hemophilia B by year-end. We also intend to initiate a Phase 2 clinical trial for our Factor VIIa product candidate Marzeptacog alfa by the end of the year. With the additional capital we raised in April, we are well positioned to report clinical data from both programs over the next 12 months.”

2017 Anticipated Milestones

• Factor IX/CB 2679d: Announce interim results from the SQ Phase 1/2 proof-of-concept clinical trial in individuals with severe hemophilia B by the end of 2017; and
• Factor VIIa/marzeptacog alfa (activated): Initiate the Phase 2 part of a Phase 2/3 SQ efficacy clinical trial in individuals with hemophilia A or B with an inhibitor by the end of 2017.

2017 Financial Highlights

• Raised $26 million through the six months ended June 30, 2017 consisting of $20.7 million raised through the underwritten public equity offering and $5.3 million raised through our Capital on DemandTM program. Cash, cash equivalents and short-term investments as of June 30, 2017 were $32.4 million (excluding restricted cash). The Company believes that its existing capital resources will be sufficient to meet its projected operating requirements for at least the next 12 months.
• Redeemable Convertible Notes balance was reduced to $5.8 million from $19.4 million at December 2016; all redemptions were funded from the restricted cash, of which an additional $5.8 million is available to fund the remaining notes.
• Research and development expense for the three months ended June 30, 2017 was $3.4 million, compared with $2.8 million for the prior year period. The increase was due primarily to manufacturing expenses for marzeptacog alfa (activated), partially offset by a decrease in personnel-related costs and a decrease in lab supply costs and costs related to preclinical third-party research and development service contracts.
• General and administrative expense for the three months ended June 30, 2017 was $2.7 million, compared with $2.3 million for the prior year period. The increase was due primarily to an increase in personnel-related costs and an increase in professional service costs indirectly related to the underwritten public offering.  
• Net loss attributable to common stockholders for the three months ended June 30, 2017 was $9.8 million, or ($2.53) per basic and diluted share, compared with $4.8 million, or ($6.33) per basic and diluted share, for the prior year period.  Convertible preferred stock’s $4.0 million deemed dividend is a non-cash, non-recurring charge.
