Spectrum Pharmaceuticals Reports Second Quarter 2019 Financial Results and Pipeline Update

Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biopharmaceutical company focused on novel and targeted oncology therapies, announced today financial results for the three-month period ended June 30, 2019.

"We've made significant progress on our pipeline in the last few months," said Joe Turgeon, President and CEO of Spectrum Pharmaceuticals. "Most notably, we completed enrollment in our first two poziotinib cohorts in the ZENITH20 study and expect to see results from cohort 1 in the fourth quarter. Based on strong science, we've expanded the poziotinib development program to include additional areas of high unmet medical need in lung cancer. We also had a productive meeting with the FDA and expect to submit the ROLONTIS BLA in the fourth quarter."

Pipeline Overview:

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

• The cornerstone poziotinb ZENITH20 trial currently consists of seven cohorts of patients with non-small cell lung cancer (NSCLC).
  • Cohorts Fully Enrolled
    • Cohort 1: Previously treated patients with EGFR exon 20 insertion mutation; topline results expected in the fourth quarter 2019
    • Cohort 2: Previously treated patients with HER2 exon 20 insertion mutation; topline results expected in mid-2020
  • Cohorts Currently Enrolling
    • Cohort 3: Treatment naïve patients with EGFR exon 20 insertion mutation
    • Cohort 4: Treatment naïve patients with HER2 exon 20 insertion mutation
    • Cohort 5: Previously treated or treatment naïve patients with EGFR or HER2 exon 20 insertion mutation
    • Cohort 6: Previously treated first-line osimertinib patients with acquired EGFR mutations
    • Cohort 7: Previously treated patients with atypical EGFR or HER2 mutation
• Spectrum expects to initiate a basket study in H2 2019.

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

• Integrated data from both Phase 3 ROLONTIS clinical trials with 643 patients were presented in a poster session at American Society of Clinical Oncology 2019 annual meeting.
  • The analysis found that integrated efficacy and safety data from the two identically designed Phase 3 trials - ADVANCE and RECOVER - were consistent with results from the individual trials, demonstrating that ROLONTIS was non-inferior to pegfilgrastim in the reduction of duration of severe neutropenia (DSN) in all four cycles of treatment.

• Spectrum met with the FDA and expects to submit the ROLONTIS BLA in the fourth quarter of 2019.

Business Development

• In May 2019, Spectrum completed an asset purchase and license agreement with ImmunGene, Inc., a privately held biotechnology company.
  • The deal includes an exclusive license for the intellectual property related to the FIT antibody-interferon fusion technology drug delivery platform and two innovative early-stage drug candidates derived from the platform.
  • Originally developed by scientists at UCLA, the FIT platform fuses interferon with a monoclonal antibody providing a mechanism for targeting many different tumor antigens and has the potential for broad application in oncology.

*This pre-tax gain on sale represents the $158.8 million proceeds from the Commercial Product Portfolio Transaction less our $121.2 book value of transferred net assets (inclusive of assumed liabilities) to Acrotech on the March 1, 2019 closing date, and after legal and banker transaction expenses for the three months ended March 31, 2019 that aggregated $3.9 million.

**This income tax provision (benefit) represents an allocation of taxes as required under the intraperiod allocation guidance. Due to our aggregate net operating loss-carryforwards, no federal or state income tax payments are expected to be made relating to our current year activity, inclusive of our gain on sale of the Commercial Product Portfolio.

***The "Product sales, net" is inclusive of our commercial product sales for January and February 2019, as well as recognized EVOMELA product sales during the second quarter of 2019 to a single customer under an active contract that was not yet assumed by Acrotech. The negative revenue value reflects actual government chargeback claims received during the three months ended June 30, 2019 that were in excess of current period revenue for this interim EVOMELA supply arrangement and our then-existing allowance for government chargebacks.

****The "Restructuring - employee severance" negative value in the second quarter of 2019 reflects a current period reclassification to continuing operations "selling, general and administrative" and "research and development" expenses. This $2.4 million amount was previously included within "income (loss) from discontinued operations, net of income taxes" in the first quarter of 2019.

Non-GAAP Financial Measures (from Continuing Operations)

In this press release, Spectrum reports certain historical results that have not been prepared in accordance with generally accepted accounting principles (GAAP), including non-GAAP selling, general and administrative expenses, non-GAAP research and development expenses, non-GAAP net loss and non-GAAP net loss per share. Non-GAAP financial measures are reconciled to the most directly comparable GAAP financial measures 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 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 these non-GAAP financial measures are useful to investors in providing greater transparency to the information used by management in its operational decision-making. Management believes that the use of these non-GAAP financial measures also facilitates a comparison of the Company's underlying operating performance with that of other companies in its industry, which use similar non-GAAP measures to supplement their GAAP 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. In addition, other companies, including other companies in our industry, may calculate non-GAAP financial measures differently than we do, limiting their usefulness as a comparative tool. Investors and potential investors are encouraged to review the reconciliation of our non-GAAP financial measures contained within this news release with our GAAP financial results.

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

(2) Non-GAAP research and development expenses (from continuing operations): 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 severance expenses and R&D milestone achievements and upfront in-license fees that we record to this expense caption. We believe this resulting non-GAAP R&D value is more indicative of our normalized R&D expense trends.

(3) Non-GAAP net loss (from continuing operations): These amounts reflect all non-GAAP adjustments described in (1) through (2) above, plus other non-cash and/or non-recurring items, including: (i) adjustments to reverse the impact of income taxes; (ii) reversal of foreign exchange gains and losses (non-cash); (iii) reversal of debt discount accretion expense (non-cash) for our convertible notes during the prior year period; and (iv) reversal of the mark-to-market adjustment (non-cash) on our equity securities holdings.

(4) Non-GAAP net loss per share (from continuing operations): These amounts reflect all non-GAAP adjustments in (1) through (3) above to present our overall non-GAAP financial results for each period on a per-share basis.
