APVO - Aptevo Therapeutics Reports First Quarter 2019 Financial Results

Achieves 73% Increase in First Quarter 2019 Year-Over-Year IXINITY® Net Revenue

On Target for Launch of New 3,000 IU IXINITY Assay Mid-2019

Advances Enrollment in APVO436 and APVO210 Phase 1 Clinical Studies; Anticipates Top-Line Preliminary Data Read-outs in the Third and Fourth Quarters of 2019

SEATTLE, May 09, 2019 (GLOBE NEWSWIRE) -- Aptevo Therapeutics Inc. (Nasdaq: APVO), a biotechnology company focused on developing novel oncology, autoimmune and hematology therapeutics, today provided a business review and reported its financial results for the first quarter ended March 31, 2019.

“As we reported in our interim business update in April, momentum in both our pipeline and IXINITY programs continues to strengthen in 2019 and we remain on track to achieve several key priorities we outlined for Aptevo this year. These include, advancing our novel, next-generation ADAPTIR candidates through preliminary top-line clinical data read-outs, driving continued adoption of IXINITY through the launch of new growth initiatives, and achieving a 33% reduction in our 2019 cash burn rate,” said Marvin L. White, President and Chief Executive Officer.

“We continue to be pleased with the revenue performance for IXINITY, with year-over-year net revenue for IXINITY in the first quarter increasing approximately 73% to $7.0 million compared to $4.1 million in the first quarter of 2018. We anticipate that new growth initiatives that are being implemented beginning this year, including the launch of a larger assay size for IXINITY and pursuit of a pediatric label expansion and ex-US distribution and partnership opportunities, will continue to drive growth of IXINITY through 2019 and beyond.”

“Turning to our ADAPTIR™ bispecific pipeline, enrollment in both of the Phase 1 clinical studies of APVO436 (Acute Myeloid Leukemia) and APVO210 (autoimmune diseases) is proceeding on target, with dosing for Cohort 3 in the APVO210 study now underway, and dosing in Cohort 3 anticipated to begin shortly for APVO436. 2019 will be an important year for our next-generation ADAPTIR platform as we anticipate reporting preliminary data read-outs for both ongoing clinical programs this year. Specifically, we anticipate reporting a preliminary read-out on anti-drug antibody (ADA) data for APVO436 in the third quarter and preliminary safety data for APVO436 in the fourth quarter. We look forward to sharing these data with investors to confirm the absence of ADA in our next-generation candidates, as industry-leading T-cell immunogenicity assays show low risk for ADA in our next generation platform.”

“For APVO210, we anticipate reporting initial results of the single dose cohorts in the third quarter and reporting preliminary safety data in the fourth quarter. We are also on track to file a clinical trial authorization (CTA) for ALG.APV-527 in the fourth quarter and anticipate beginning Phase 1 clinical development in 2020. We’re very encouraged by the progress in our ADAPTIR clinical programs as the first clinical data from our next generation candidates becomes available later this year. As we’ve previously announced, in preclinical studies, APVO436 showed important differentiation from a competitor bispecific molecule, demonstrating comparable T-cell activation and tumor killing but with less cytokine activation, which could have important advantages with respect to dosing and the therapeutic index for this molecule. We look forward to evaluating these attributes in our ongoing APVO436 clinical program and determining the safety and tolerability profile of APVO210, as a potential first-in-class novel autoimmune therapy,” concluded Mr. White.

First Quarter 2019 Highlights

• Achieved 73% increase in year-over-year IXINITY net revenue in the first quarter of 2019 through continued expansion of the patient base for IXINITY
• Progressed plans to launch a new 3,000 IU assay for IXINITY; received approval from the U.S. Food and Drug Administration (FDA) for a Prior Approval Supplement (PAS) describing plans for the manufacture of the new 3,000 IU assay; on track to launch new 3,000 IU assay in mid-2019
• Commenced a Phase 1 clinical study of APVO210 designed to evaluate single and multiple ascending doses in healthy volunteers; dosing in Cohort 3 currently underway; anticipate reporting initial results of the single dose cohorts in the third quarter and reporting preliminary safety data in the fourth quarter of 2019
• Continued enrollment in a dose escalation Phase 1/1b open-label clinical study of APVO436 in patients with Acute Myeloid Leukemia (AML) and High-Grade Myelodysplastic Syndrome (MDS); dosing in Cohort 3 anticipated to commence shortly; anticipate reporting preliminary ADA read-out in the third quarter and reporting preliminary Phase 1 safety data in the fourth quarter of 2019
• Presented new preclinical data for APVO436 at the American Association for Cancer Research (AACR) 2019 annual meeting demonstrating T cell differentiation into effector cells with exposure to APVO436 in preclinical studies, in addition to key data demonstrating potent T-cell cytotoxicity of tumors expressing CD123 with reduced cytokine release, suggesting the potential for increased clinical benefit and an improved safety profile
• Presented new preclinical data for ALG.APV-527 at AACR showing that it was well tolerated in a dose-range finding pilot toxicology study demonstrating no major changes in liver enzyme levels, cytokine levels or immune cell populations, and had an extended half-life of 5-7 days
• Implemented a 33% reduction in Aptevo’s 2019 annual cash burn rate; anticipate 2019 cash burn of between $36-$40 million compared to $55-60 million in 2018
• Completed a public equity offering in March 2019 raising gross proceeds of approximately $22 million for Aptevo, strengthening the company’s balance sheet and providing additional cash runway beyond validating clinical milestones in the APVO436 and APVO210 Phase 1 clinical development programs anticipated in the third and fourth quarters of 2019, respectively

First Quarter 2019 Financial Results

Cash Position: Aptevo had cash, cash equivalents, and marketable securities as of March 31, 2019 totaling $44.5 million, including $7.5 million in restricted cash.

IXINITY Revenue: Product sales of IXINITY increased by $3.0 million, or 73%, to $7.0 million for the three months ended March 31, 2019, compared to $4.1 million for the same period in 2018. The increase in IXINITY sales in the quarter was primarily related to the continuing expansion of the Hemophilia B patient base for IXINITY and a price increase which went into effect on January 1, 2019.

Cost of Product Sales: Cost of product sales for the three months ended March 31, 2019 increased by $2.1 million, or 116% to $3.8 million compared to $1.8 million for the three months ended March 31, 2018. The increase in cost of product sales is primarily due to the increase in sales in the current quarter as well as the first quarter of 2018 having reduced cost of goods sold due to lower cost inventory that was sold during that quarter.

Research and Development Expenses: Research and development expenses decreased by $0.9 million, to $7.3 million for the three months ended March 31, 2019, compared to $8.2 million for the corresponding period in 2018. The decrease was primarily attributable to a decrease in expenses related to the APVO436 and APVO210 clinical programs, primarily due to the timing of certain manufacturing and clinical trial activities, offset by an increase in expenses related to Aptevo’s preclinical programs and general research and development efforts, and an increase in R&D expense for IXINITY related to start-up costs associated with the pediatric clinical study expected to commence in 2019.

Selling, General and Administrative Expenses: Selling, general and administrative expenses decreased by $0.3 million, or approximately 3%, to $7.3 million for the three months ended March 31, 2019, compared to $7.6 million for the same period in 2017. The decrease in SG&A expenses in the first quarter of 2019 was primarily due to reduced personnel and professional services costs.

Net Loss: Aptevo’s net loss for the three months ended March 31, 2019 was $(12.0) million or ($0.44) per share, compared to $(13.9) million or ($0.63) per share for the three months ended March 31, 2018.
