Catalyst Biosciences Reports Third Quarter 2019 Operating & Financial Results and Provides a Corporate Update

SOUTH SAN FRANCISCO, Calif., Nov. 07, 2019 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (NASDAQ: CBIO) today announced its operating and financial results for the third quarter ended September 30, 2019 and provided a corporate update.

“We continued to make progress in both the marzeptacog alfa (activated) (MarzAA – FVIIa) and dalcinonacog alfa (DalcA – FIX) clinical programs,” said Nassim Usman, Ph.D., president and chief executive officer of Catalyst. “We presented final MarzAA Phase 2 clinical data that clearly demonstrated the potential for subcutaneously (SQ) dosed MarzAA as a prophylactic treatment for hemophilia A or B patients with inhibitors. In addition, we showed that SQ MarzAA can treat a bleed in a preclinical model and completed GMP manufacturing of MarzAA at commercial scale, important steps as we prepare for a pivotal Phase 3 trial in 2020. In the DalcA Phase 2b trial, we successfully completed dosing in two subjects, achieving high FIX activity levels with a long SQ half-life without eliciting anti-drug antibodies (ADAs).”

Recent Milestones:       

  • Marzeptacog alfa (activated) – MarzAA, a subcutaneously administered next-generation engineered coagulation Factor VIIa (FVIIa): 
    Presented final Phase 2 data for MarzAA at ISTH in July: The study met the primary endpoint of significantly reducing (>90%) the annualized bleed rate (ABR) in patients with hemophilia A or B with inhibitors from 19.8 to 1.6 (p<0.01). The study also met all secondary endpoints of safety, tolerability and absence of ADAs or inhibitor formation. Additionally, the Proportion of Days with Bleeding (PDB), was significantly reduced from a 6-month pretreatment mean of 12.3% to 0.8% during treatment (p<0.01). The median ABR and PDB were both reduced to zero during treatment, with seven of nine subjects experiencing no bleeds, either traumatic or spontaneous, at their final dose level. Subcutaneous treatment with MarzAA was safe and well-tolerated. Six mild to moderate localized skin reactions were observed in 2 subjects. No ADAs or inhibitors to MarzAA were detected after administration of a total of 517 SQ doses.

    Hosted a Key Opinion Leader meeting in August highlighting the current treatment landscape, market opportunity and unmet medical need for MarzAA in treating individuals with hemophilia A or B with inhibitors, Factor VII deficiency and other bleeding disorders, and the potential for an SQ therapy to treat bleeding.

    Completed a GMP drug product batch at commercial scale that is expected to support pivotal studies and commercialization requirements.

    Continued to enroll a Phase 1 SQ pharmacokinetic and pharmacodynamic study of MarzAA in individuals with hemophilia A or B (with or without inhibitors). The purpose of the trial is to guide dose selection to treat a bleed with SQ dosing.
  • Dalcinonacog alfa – DalcA, a subcutaneously administered next-generation engineered coagulation Factor IX (FIX):

    Completed 28-day SQ dosing and 30-day washout and safety follow-up of two subjects in the open-label Phase 2b study evaluating the efficacy and safety of DalcA with long-term dosing in individuals with severe hemophilia B. Factor IX levels in these two subjects exceeded the efficacy endpoint of >12% activity and no ADAs or inhibitors were detected. Enrollment is ongoing and the Company anticipates reporting final data in the first half of 2020.

Expected Milestones:

  • MarzAA:  Initiate a Phase 3 trial in 2020 following the end of Phase 2 meeting with the FDA and report final data from a MarzAA Phase 1 pharmacokinetic and pharmacodynamic study to support future SQ treatment of bleed studies.
  • DalcAA:  Report final Phase 2b trial data in the first half of 2020.

Third Quarter 2019 Results and Financial Highlights:

  • Cash, cash equivalents and short-term investments, as of September 30, 2019 were $85.0 million.
  • Research and development expenses were $9.9 million and $5.6 million during the three months ended September 30, 2019 and 2018, respectively, an increase of $4.4 million, or 78%. The increase was due primarily to an increase of $1.7 million in clinical and manufacturing development as the Company continued to advance the development of the MarzAA and DalcA product candidates, an increase of $1.6 million in preclinical research inclusive of projects supportive of the product candidates, and an increase of $1.0 million in personnel-related costs.
  • General and administrative expenses were $3.3 million and $2.8 million during the three months ended September 30, 2019 and 2018, respectively, an increase of $0.5 million, or 18%. The increase was due to an increase in professional services driven by corporate activities.
  • Interest and other income was $0.5 million and $0.7 million during the three months ended September 30, 2019 and 2018, respectively. The decrease was due to lower average cash equivalent and short-term investments balances during the 2019 period.
  • Net loss attributable to common stockholders for the three-months ended September 30, 2019 was $12.7 million, or ($1.06) per basic and diluted share, compared with $7.7 million, or ($0.64) per basic and diluted share, for the prior year period.
  • As of September 30, 2019, the Company had 12,029,992 shares of common stock outstanding.
