HENDERSON, Nev.--(BUSINESS WIRE)--Aug. 9, 2018-- Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations with a primary focus in hematology and oncology, announced today financial results for the three-month period ended June 30, 2018.

“The second quarter marked significant progress and data milestones for our two lead programs poziotinib and ROLONTIS, moving us closer to our ultimate goal of delivering targeted and novel therapies to cancer patients,” said Joe Turgeon, President and Chief Executive Officer of Spectrum Pharmaceuticals. “We have strong momentum going into the second half of the year as we aggressively broaden our poziotinib clinical program and continue to gain additional regulatory clarity.”

Clinical Program Overview:

Poziotinib, an irreversible tyrosine kinase inhibitor targeting EGFR and HER2 mutations:

• Updated data from the MD Anderson Phase 2 trial in non-small cell lung cancer with exon 20 mutations will be presented at the World Conference on Lung Cancer in Toronto on September 24. Updated data will include EGFR and HER2 patients with exon 20 mutations. The abstract will be released online on September 5.
• Spectrum recently had a meeting with the FDA regarding poziotinib to gain clarity on the regulatory pathway. Based on that conversation, Spectrum views the current poziotinib phase 2 study as the pivotal registrational trial needed for the Agency’s review.
• Data published in Nature Medicine from the first 11 NSCLC patients with EGFR exon 20 mutations receiving poziotinib in MD Anderson’s Phase 2 clinical trial demonstrated a confirmed objective response rate of 64 percent. The median progression-free survival had not been reached, with a median follow up of 6.6 months. The safety profile was consistent with what has been previously described for poziotinib and other TKIs with the two most common adverse events being known EGFR inhibitor-related toxicities: skin rash and diarrhea.
• Data presented at AACR demonstrated that HER2 exon 20 mutations were prevalent across multiple solid tumors.

ROLONTIS (eflapegrastim), a novel long-acting GCSF:

• Spectrum plans to conduct a pre-BLA meeting in the third quarter to ensure alignment with the FDA in preparation for a planned BLA filing in the fourth quarter of 2018.
• Top line data from RECOVER, the second Phase 3 ROLONTIS study, demonstrated that the study met the primary efficacy endpoint of non-inferiority in the duration of severe neutropenia (DSN) between ROLONTIS and pegfilgrastim. Both Phase 3 ROLONTIS clinical trials, ADVANCE and RECOVER which studied more than 600 patients combined, have met the primary efficacy endpoint. Additional RECOVER data will be released at a future medical meeting.
• ADVANCE data released as part of ASCO 2018 demonstrated that ROLONTIS was non-inferior to pegfilgrastim in the reduction of duration of severe neutropenia (DSN) in all four cycles of the study. Mean DSN±SD was 0.19±0.478 days for ROLONTIS and 0.34±0.668 days for pegfilgrastim, demonstrating non-inferiority with 95 percent confidence interval (CI) of DSN: [-0.260, -0.035]; p<0.0001) in Cycle 1. There were no statistically significant differences in all secondary endpoints in Cycle 1. The adverse event profiles were similar across groups. The most common treatment emergent adverse events in both treatment arms were fatigue, nausea, neutropenia, and lymphopenia.
• In an oral presentation at MASCC 2018, data from the ADVANCE Phase 3 study demonstrated an absolute risk reduction of severe neutropenia of 8.5 percent (95% CI: 0.2%, 16.2%) versus pegfilgrastim in Cycle 1. Absolute risk reduction was defined as the difference in percentage of patients experiencing no severe neutropenia (ROLONTIS 84.2 percent; pegfilgrastim 75.7 percent).

Financial Guidance

Spectrum’s 2018 revenue guidance remains between $95 to $115 million. Additionally, Spectrum anticipates current cash and marketable securities will be sufficient to fund operations into 2020.

Non-GAAP Financial Measures

In this press release, Spectrum reports certain historical and expected non-GAAP results. Non-GAAP financial measures are reconciled to the most directly comparable GAAP financial measure in the tables of this press release and the accompanying footnotes. The non-GAAP financial measures contained herein are a supplement to the corresponding financial measures prepared in accordance with generally accepted accounting principles (GAAP). The non-GAAP financial measures presented exclude the items summarized in the below table. Management believes that adjustments for these items assist investors in making comparisons of period-to-period operating results and that these items are not indicative of the company's on-going core operating performance.

Management uses non-GAAP net income (loss) in its evaluation of the company's core after-tax results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Management believes that providing these non-GAAP financial measures allows investors to view the company's financial results in the way that management views the financial results.

The non-GAAP financial measures presented herein have certain limitations in that they do not reflect all of the costs associated with the operations of the company's business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The non-GAAP financial measures presented by the company may be different from the non-GAAP financial measures used by other companies.

(1) Non-GAAP product sales, net & license fees and service revenue: These amounts reflect adjustments to reverse revenue recognition for upfront revenue from out-licenses and revenue from milestone achievement(s) that do not consistently recur. The resulting non-GAAP revenue solely consists of our (i) product sales, (ii) percentage-based royalties from our licensees’ sales, and (iii) on-going service revenue. We believe this measure of non-GAAP revenue is more indicative of the period-over-period success of our core ongoing product sales and service revenue.

(2) Non-GAAP selling, general and administrative: These amounts reflect adjustments to reverse allocated operating expenses for certain non-cash items (including stock-based compensation and depreciation). We believe the resulting non-GAAP SG&A value is more indicative of the period-over-period success of our administrative expense control, and more reflective of our normalized SG&A expense trends.

(3) Non-GAAP research and development: These amounts reflect adjustments to reverse allocated operating expenses for certain non-cash items (including stock-based compensation and depreciation), as well as non-recurring R&D milestone achievements that we record to expense for our in-licenses. We believe the resulting non-GAAP R&D value is more reflective of our true R&D expense trends.

(4) Non-GAAP net loss: These amounts reflect all non-GAAP adjustments described in (1) through (3) above, plus other non-cash and/or non-recurring items, including: (i) adjustments to reverse sales milestone achievements; (ii) adjustments to reverse operating expenses for non-cash amortization and impairment of intangible assets (the reversal of these non-cash expenses allows for a clearer representation of the period-over-period success of our overall financial results and future working capital requirements); (iii) adjustments to reverse the impact of income taxes; (iv) adjustments to reverse the impact of mark-to-market contingent consideration (although our contingent consideration results from prior acquisitions and is a part of our business strategy, these adjustments through earnings typically result from variables other than our current commercial activity or other operating performance measures that are a focus of our management), (v) reversal of foreign exchange gains and losses (non-cash), (vi) reversal of debt discount accretion expense (non-cash) for our convertible notes, and (vii) reversal of the mark-to-market adjustment on our equity securities.

(5) Non-GAAP loss per share: These amounts reflect all non-GAAP adjustments in (1) through (4) above to present our overall non-GAAP financial results for each period on a per-share basis.
