ANAHEIM, Calif., July 30, 2013 /PRNewswire/ -- Questcor Pharmaceuticals, Inc. (NASDAQ: QCOR) today reported financial results for the second quarter and six months ended June 30, 2013.

Net sales for the second quarter ended June 30, 2013 were $184.6 million, up 64% from $112.5 million in the second quarter of 2012. The increase was driven primarily by the expanded usage of H.P. Acthar^® Gel (repository corticotropin injection) by rheumatologists in the treatment of patients suffering from dermatomyositis, polymyositis, systemic lupus erythematosus, and rheumatoid arthritis. The increase in net sales was also driven by increased prescribing by nephrologists in the treatment of nephrotic syndrome (NS) and by neurologists in the treatment of multiple sclerosis (MS) relapses and infantile spasms (IS). GAAP earnings for the second quarter of 2013 were $1.12 per diluted common share, compared to $0.65 per diluted common share for last year's comparable quarter. BioVectra, the company's specialty manufacturing subsidiary which was acquired in January 2013, had net sales of $7.5 million in the second quarter of 2013.

Net sales for the second quarter include the effect of the Company's decision to accrue, based on information received in the quarter, an incremental Medicaid rebate liability of $11.5 million related to Questcor's 2001 entry into the Medicaid system subsequent to Questcor's acquisition of Acthar in 2001. The incremental liability covers periods from 2002 to 2009. Due to health care legislation passed in early 2010, there is no incremental liability for periods subsequent to 2009. On a non-GAAP basis, excluding this charge, net sales for the second quarter were $196.1 million, up 74% over the second quarter of 2012. Non-GAAP earnings for the second quarter of 2013 were $1.35 per diluted common share and exclude the incremental rebate liability, non-cash share-based compensation expense, and depreciation and amortization expense. Non-GAAP earnings for the year ago quarter were $0.69 per diluted common share. The reconciliation between GAAP and non-GAAP financial measures is provided with the financial tables included with this release.

Questcor shipped 7,050 vials of Acthar during the second quarter of 2013, up 50 percent compared to 4,710 vials in the year ago quarter. As the Company has previously disclosed, quarterly vial shipments are subject to significant variation due to the size and timing of individual orders received from Questcor's distributor. The timing of when these orders are received and filled can significantly affect net sales and net income in any particular quarter. The Company believes that investors should consider the Company's results over several quarters when analyzing the Company's performance.

"Our commercial expansion effort continues, most recently driven by increasing usage of Acthar among rheumatologists," said Don M. Bailey, President and CEO of Questcor. "The foundation for potential additional growth over the near-, medium- and long-term continues to strengthen. The first full quarter of our commercial rheumatology effort generated over 300 prescriptions, marking the best Acthar launch into a new therapeutic area that we have yet experienced. This rapid success has encouraged us to accelerate our entry into pulmonology, where we recently announced a pilot commercialization effort for respiratory manifestations of symptomatic sarcoidosis, a labeled indication for Acthar. We also continue to assess additional indications on the Acthar label for other commercial opportunities, as well as explore the use of Acthar for possible new indications, as demonstrated by the initiation of our Phase 2 study in amyotrophic lateral sclerosis (ALS). This is our second phase 2 trial, as we continue to proceed with our trial in diabetic nephropathy. Additionally, in the second quarter we acquired the rights to Synacthen^®, which will further expand our melanocortin peptide R&D program. This action provides us a platform for potential further U.S. growth and the initiation of international commercial activity for Synacthen and potentially for Acthar."

"Total new paid prescriptions for Acthar were approximately 2,250 to 2,275 in the second quarter, an increase of about 35% year-over-year," commented Steve Cartt, Chief Operating Officer of Questcor. "There were 400 to 405 new paid prescriptions for NS in the quarter, up about 19% year-over-year. NS prescriptions currently account for around 40% of our Acthar business. During the second quarter there were 1,285 to 1,295 new paid prescriptions for MS, up about 12% year-over-year and up 27% sequentially. MS prescriptions currently represent over a quarter of our Acthar business. New paid prescriptions for IS were 210 to 215, up 27% year-over-year. Quite encouragingly, there were also 315 to 320 new paid Acthar prescriptions for approved rheumatology indications during the second quarter, which was the first full commercial quarter of Questcor promoting Acthar in this therapeutic area."

Mr. Cartt continued, "The vial shipment activity and prescription levels seen in late March and in April extended through the second quarter. In particular, we are experiencing solid uptake of Acthar in the approved rheumatology-related indications dermatomyositis and polymyositis, and we are also beginning to see a growing number of prescriptions for rheumatoid arthritis and lupus, both of which are on-label."

The Company believes that insurance coverage for Acthar continues to remain favorable, when Acthar is prescribed for on-label indications for patients in need of an additional FDA-approved treatment alternative.

To allow comparable analysis, the Company has defined "new paid" prescriptions in the above paragraphs to include prescriptions covered by commercial carriers, Medicare, Medicaid and Tricare in all periods regardless of the rebate percentage applicable in those periods. The numbers are based on internal company estimates and do not include prescriptions filled through the Acthar free drug program.

Year-to-Date Financial Results

Net sales for the first six months of 2013 were $319.7 million, with BioVectra contributing $15.9 million. On a non-GAAP basis, net sales for the first six months were $331.2 million. Net sales in the first six months of 2012 were $208.4 million. GAAP earnings for the first six months of 2013 were $1.79 per diluted common share, compared to $1.23 per diluted common share for the comparable period of 2012. Non-GAAP earnings for the six months ended June 30, 2013 were $2.13 per diluted common share excluding non-cash share-based compensation expense, depreciation and amortization expense, and the incremental rebate adjustment. Non-GAAP earnings for the comparable period of 2012 were $1.29 per diluted common share. The reconciliation between GAAP and non-GAAP financial measures is provided with the financial tables included with this release.

Research and Development Progress

"Questcor's continued strong financial performance has enabled the Company to increase investment in research programs to further clarify the potential immune-modulating properties of Acthar and identify Acthar mechanisms of action applicable to other inflammatory and auto-immune diseases with high unmet medical need," noted Dr. David Young, Chief Scientific Officer. "The Company is also identifying new patient populations in which to evaluate Acthar through clinical studies. Questcor has funded or has approved funding for approximately 70 research projects, including company-sponsored clinical and pre-clinical studies and independent physician sponsored studies."

Research and development (R&D) investment increased 44% to $12.2 million in the three months ended June 30, 2013, as compared to $8.5 million for the year ago period. R&D investments were $23.0 million for the first six months of 2013, as compared to $14.2 million for the year ago period.

Label Enhancement Programs:

• Amyotrophic Lateral Sclerosis (ALS): Questcor commenced screening patients for enrollment into a dose-ranging Phase 2 clinical trial to evaluate the safety and tolerability of Acthar in patients with ALS, often referred to as Lou Gehrig's disease. ALS is a life-threatening, progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.
• Diabetic Nephropathy: Enrollment continues in a company-sponsored Phase 2 trial to evaluate the efficacy and safety of Acthar in patients with diabetic nephropathy, one of the most common causes of end-stage renal disease in the United States.

Research Regarding Approved Indications:

• Idiopathic Membranous Nephropathy: Enrollment continues in a company-sponsored Phase 4 trial in idiopathic membranous nephropathy. Patients enrolled in this study are refractory, or non-responsive, to current standard therapies or have relapsed after partial remission on current standard therapies.
• Lupus: Enrollment continues in a company-sponsored multi-site Phase 4 company-sponsored clinical trial to evaluate the efficacy and safety of daily Acthar administration over a 6-month period in patients with persistently active lupus.
• Lupus Exacerbations: Questcor is providing grant support for a prospective independent investigator initiated study evaluating Acthar in the treatment of lupus exacerbations. The Company has been informed by the investigator that this study has recently been completed.

Planning activities related to the initial evaluation of a select grouping of potential Synacthen indications are in process. Questcor will provide further updates on this newly initiated development program as key activities get underway.

Cash, Share Repurchase Program and Dividends

As of July 26, 2013, Questcor had cash, cash equivalents and short-term investments of $115.6 million, and restricted cash of $75.0 million set aside to secure certain post-closing payment obligations related to Questcor's acquisition of Synacthen. There were no share repurchases during the second quarter of 2013 and Questcor had 6.3 million remaining authorized shares under the Company's existing common stock repurchase plan. Diluted shares outstanding at June 30, 2013 were 61.5 million shares.

The Company issued its second quarter cash dividend of $0.25 per share to all shareholders of record at the close of business on July 22, 2013. The dividend is scheduled to be paid today, July 30, 2013. Questcor currently intends to pay regular quarterly cash dividends for the foreseeable future.

Acthar Label Information

The product label for Acthar includes 19 FDA-approved indications. Substantially all of the Company's net sales currently result from Acthar prescriptions for the following on-label indications of:

• Nephrotic Syndrome (NS): "to induce a diuresis or a remission of proteinuria in the nephrotic syndrome without uremia of the idiopathic type or that due to lupus erythematosus." NS can result from several underlying conditions, and prescribing physicians indicate that Acthar is most commonly being prescribed for patients who suffer from NS due to idiopathic membranous nephropathy, focal segmental glomerulosclerosis (FSGS), IgA nephropathy, minimal change disease and lupus nephritis.
• Multiple Sclerosis (MS): "for the treatment of acute exacerbations of multiple sclerosis in adults. Clinical controlled trials have shown H.P. Acthar Gel to be effective in speeding the resolution of acute exacerbations of multiple sclerosis. However, there is no evidence that it affects the ultimate outcome or natural history of the disease." When Acthar is used, it is typically prescribed as second line treatment for patients with MS exacerbations.
• Infantile Spasms (IS): "as monotherapy for the treatment of infantile spasms in infants and children under 2 years of age."
• Collagen Diseases: "during an exacerbation or as maintenance therapy in selected cases of: systemic lupus erythematosus, systemic dermatomyositis (polymyositis)."
• Rheumatic Disorders: "as adjunctive therapy for short-term administration (to tide the patient over an acute episode or exacerbation) in: Psoriatic arthritis, Rheumatoid arthritis, including juvenile rheumatoid arthritis (selected cases may require low-dose maintenance therapy), Ankylosing spondylitis."

Non-GAAP Financial Measures

The Company believes it is important to share non-GAAP financial measures with investors as these measures may better represent the ongoing economics of the business and reflect how we manage the business. Accordingly, management believes investors' understanding of the Company's financial performance is enhanced as a result of the disclosure of these non-GAAP financial measures. Non-GAAP financial measures should not be viewed in isolation, or as a substitute for, or as superior to, reported GAAP financial measures. The reconciliation between GAAP and Non-GAAP financial measures are provided with the financial tables included with this release.
