OREANDA-NEWS. Anthera Pharmaceuticals, Inc. (Nasdaq:ANTH) today provided a business update and reported financial results for the second quarter ended June 30, 2016.

Recent Developments and Business Highlights:

Sollpura™ (liprotamase) – Exocrine Pancreatic Insufficiency (“EPI”)

  • Phase 3 SOLUTION Clinical Study Enrollment Target of 126 Patients Met
    We met the enrollment target in our Phase 3 SOLUTION clinical study evaluating the efficacy and safety of the capsule formulation of Sollpura™ to treat exocrine pancreatic insufficiency in patients with cystic fibrosis in early August.  We expect to report topline efficacy data in the fourth quarter of 2016. For more information on the SOLUTION clinical study, please visit http://www.anthera.com/clinical-studies/solution study/.
  • Initiated SIMPLICITY Clinical Study with an Enrollment Target of 46 Patients
    We began dosing patients in the SIMPLICITY clinical study which is evaluating the efficacy and safety of Sollpura™ supplied as a powder for oral solution.  In this study, Sollpura is packaged in a convenient, easy-to-administer packet.  The soluble dose form of all three digestive enzymes is mixed with water or apple juice.  After an initial cohort of patients older than seven is treated for one week, this study will allow for administration of Sollpura™ powder for oral solution to pediatric patients ranging in age from 28 days to seven years.  For more information on the study, please visit http://www.anthera.com/clinical-studies/simplicity-study/. 
  • Manufacturing Progressing to Support SIMPLICITY Study and Commercial Readiness 
    We successfully manufactured and released two sachet dosage strengths with a newly developed dry powder formulation for oral solution, enabling the initiation of the SIMPLICITY clinical study. We made progress with manufacturing technical transfer of all three enzymes to our contract manufacturers site. We completed demonstration batch manufacturing at commercial launch scale for lipase. Additionally, proof-of-concept was demonstrated for a high dose Lipase unit capsule – a further step towards reducing capsule burden in patients with EPI.

Blisibimod - Systemic Lupus Erythematosus (“SLE”)

  • Topline Data from Phase 3 CHABLIS-SC1 Clinical Study 
    We continue to collect and prepare final data from the Phase 3 CHABLIS-SC1 clinical study as the final patients continue treatment in the study.  The last patient in the study received their final study dose on July 28th.  As described in the protocol, patients are followed for eight weeks after their last dose at which time the final safety data is collected. Due to timing of this final visit, the company expects topline efficacy and safety data will be available prior to the annual American College of Rheumatology Annual Meeting in November. Topline data from the CHABLIS-SC1 will include the primary endpoint evaluation, a six-point reduction in the Systemic Lupus Erythematosus Responder Index (SRI-6) as well as safety and tolerability data from the study.

  • Phase 3 CHABLIS 7.5 Clinical Study Initiated
    CHABLIS 7.5, Anthera’s second Phase 3 clinical study successfully enrolled its first patient. This study will evaluate the efficacy and safety of blisibimod in patients who, despite corticosteroid use, continue to have clinically-active lupus (SLE) and the presence of anti-double-stranded DNA and low complement which are of known serological markers of lupus.

Blisibimod – IgA Nephropathy

  • Positive Trends Reported on Phase 2 BRIGHT-SC Clinical Study
    In June 2016, interim data from the BRIGHT-SC study, which enrolled 57 patients, demonstrated a positive trend in lower proteinuria in blisibimod versus placebo treated patients. While the numerical reduction in proteinuria in blisibimod versus placebo treated patients at week 24 in the BRIGHT-SC study did not meet the predefined primary endpoint of complete or partial response, longer-term data from the study demonstrated an increasingly large separation in proteinuria favoring the blisibimod treated arm compared to placebo. Additionally, secondary biomarker data from the study, including changes in total B cell counts and changes in immunoglobulins IgA, IgG, and IgM, were highly consistent with previous studies with blisibimod and demonstrated marked reduction after 8 weeks on study.  As a result of the increasing proteinuria effect after 24 weeks of dosing, and the demonstration of blisibimod’s effect on immunological markers relevant to IgA nephropathy including reductions of B cells, and immunoglobulins including IgA, IgG and IgM, we elected to continue the study until the last subject enrolled completes 48 weeks of evaluation.

Summary of Financial Results

  • Cash Position.  We ended the second quarter of 2016 with cash and cash equivalents totaling $28.5 million, compared to $47.0 million as of December 31, 2015. The decrease in cash was mainly attributable to research, development and operating expenses during the six months ended June 30, 2016.
  • R&D Expense.  Research and development expenses for the three and six months ended June 30, 2016 totaled $12.0 million and $21.6 million, respectively, compared to $8.5 million and $14.5 million for the corresponding periods in 2015. The increase is mainly attributable to higher clinical development expenses resulting from the acceleration of patient enrollment in the SOLUTION clinical study, the initiation of the SIMPLICITY clinical study, manufacturing scale-up costs associated with Sollpura, and the initiation of the CHABLIS-7.5 clinical study in severe lupus patients.
  • G&A Expense.  General and administrative expenses for the three and six months ended June 30, 2016 totaled $2.6 million and $4.8 million, respectively, compared to $1.7 million and $3.6 million for the corresponding periods in 2015. The increase is primarily due to higher non-cash stock-based compensation expense of $0.6 million and $0.9 million, respectively, recognized during the three and six months ended June 30, 2016. 
  • Research Award.  A research award, granted to us in March 2015 by the Cystic Fibrosis Foundation Therapeutics, Inc. and recorded as an offset to operating expense, totaled $261,000 for the three and six months ended June 30, 2016.  The amount of research award recognized represents the value prescribed to the milestones that we achieved under the award agreement during the current period.  There were no research award amounts recorded during the comparative period in 2015.
  • Net Loss.  Net loss for the three and six months ended June 30, 2016 was $14.3 million, or $0.35 per basic and diluted share and $26.1 million, or $0.64 per basic and diluted share, respectively, compared to $8.9 million, or $0.25 per basic and diluted share and $16.6 million, or $0.52 per basic and diluted share for the corresponding periods in 2015.
