Seagen Inc. (Nasdaq:SGEN) today reported financial results for the fourth quarter and year ended December 31, 2020. The Company also highlighted ADCETRIS® (brentuximab vedotin), PADCEV® (enfortumab vedotin-ejfv) and TUKYSA® (tucatinib) commercial and development accomplishments, as well as progress with its lead pipeline programs to treat cancer.

“In 2020, we generated record product revenues of more than $1 billion driven by successful launches of PADCEV and TUKYSA, as well as continued growth of ADCETRIS,” said Clay Siegall, Ph.D., President and Chief Executive Officer of Seagen. “These strong results are in addition to several significant business, regulatory and development accomplishments during the year. Looking ahead, we are focused on maximizing the global potential of our approved medicines, advancing our late-stage programs towards securing approvals of new products, and expanding our innovative early-stage pipeline. In collaboration with our partner Genmab we submitted a BLA for tisotumab vedotin to the FDA, positioning it to be our fourth commercial product. We are on track for several other milestones across our pipeline over the course of 2021, and are in a strong financial position to continue executing against our goals.”

COMMERCIAL PRODUCT HIGHLIGHTS

ADCETRIS

  • Presented 5-year Follow-up Results for ECHELON-1 and ECHELON-2 Trials at the ASH Annual Meeting: Key long-term updates for two phase 3 ADCETRIS trials were presented at the 62nd American Society of Hematology (ASH) annual meeting. Notably, the five-year update of the phase 3 ECHELON-1 clinical trial showed treatment with ADCETRIS in combination with AVD (Adriamycin [doxorubicin], vinblastine and dacarbazine) resulted in superior long-term outcomes when compared to ABVD, which includes bleomycin, in frontline advanced Hodgkin lymphoma.

PADCEV

  • Reporting Phase 3 EV-301 and EV-201 Cohort 2 Data in Oral Presentations at ASCO GU; Regulatory Submissions Planned: Full results from the phase 3 EV-301 trial and the second cohort of the pivotal phase 2 EV-201 trial will be presented at the 2021 American Society of Clinical Oncology's Genitourinary Cancers Symposium (ASCO-GU) being held February 11-13. Both trials were conducted in patients with previously treated locally advanced or metastatic urothelial cancer. The EV-301 data are intended to support global registration submissions planned for the first quarter of 2021. The results from the second cohort of EV-201 will support a supplemental Biologics License Application (BLA) submission with the U.S. Food and Drug Administration (FDA) planned for the first quarter of 2021.
  • Initiated Second Phase 3 Trial in Muscle Invasive Bladder Cancer (MIBC): In collaboration with Astellas and Merck, the randomized phase 3 EV-304/KEYNOTE-B15 trial was initiated to evaluate PADCEV in combination with KEYTRUDA® (pembrolizumab) in cisplatin-eligible MIBC. This is in addition to the ongoing randomized phase 3 study, EV-303/KEYNOTE-905, in cisplatin-ineligible MIBC patients.

TUKYSA

  • Received Positive CHMP Opinion for TUKYSA: In December 2020, the European Medicines Agency adopted a positive opinion recommending the approval of TUKYSA in combination with trastuzumab and capecitabine for the treatment of adult patients with HER2-positive locally advanced or metastatic breast cancer who have received at least 2 prior anti-HER2 treatment regimens. The CHMP positive opinion is now being considered by the European Commission, which has the authority to approve medicines in the European Union.
  • Presented Multiple TUKYSA Abstracts at SABCS: In December 2020, eight abstracts highlighted Seagen's commitment to addressing unmet needs in breast cancer at the San Antonio Breast Cancer Symposium (SABCS). One presentation provided new exploratory analyses from the pivotal HER2CLIMB trial in metastatic HER2-positive breast cancer that demonstrated progression-free survival, overall survival and objective response rate improvements with TUKYSA were observed consistently across hormone receptor status subgroups, including in patients with brain metastases.

PIPELINE HIGHLIGHTS

  • Submitted Tisotumab Vedotin BLA to FDA: In February 2021, Seagen and Genmab submitted a BLA to the FDA seeking accelerated approval of tisotumab vedotin for the treatment of patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. Results from the innovaTV 204 trial formed the basis of the submission.
  • Initiated Phase 3 Trial of Tisotumab Vedotin: A phase 3 trial, called innovaTV 301, was initiated to evaluate tisotumab vedotin compared to chemotherapy in patients with recurrent or metastatic cervical cancer who have received one or two prior lines of therapy. innovaTV 301 is intended to support global regulatory applications and potentially serve as a confirmatory trial in the U.S.
  • Treated First Patient in Phase 1 Trial of SGN-STNV: In January 2021, the first patient was dosed in a phase 1 trial of SGN-STNV, a novel antibody-drug conjugate (ADC) targeting Sialyl Thomsen-nouveau (STN). STN is highly expressed across multiple solid tumors.

  • Royalty Revenues: Royalty revenues in the fourth quarter were $39.2 million, compared to $72.3 million in the fourth quarter of 2019. The fourth quarter of 2019 included a $40 million milestone from Takeda triggered by annual net sales exceeding $400 million in Takeda's territory during 2019. Royalty revenues were $126.8 million for the full year in 2020, compared to $138.5 million in 2019. Royalty revenues are primarily driven by sales of ADCETRIS outside the U.S. and Canada by Takeda and, to a lesser extent, also include royalties from sales of POLIVY® (polatuzumab vedotin) by Roche and BLENREP® (belantamab mafodotin) by GlaxoSmithKline, which are ADCs that use Seagen technology.
  • Collaboration and License Agreement Revenues: Amounts earned under the Company’s collaboration and license agreements were $267.9 million in the fourth quarter and $1.0 billion for the full year in 2020, compared to $51.1 million and $150.2 million, respectively, for the same periods in 2019. The fourth quarter of 2020 included $250.1 million in revenue related to the premium over market price paid by Merck under a $1 billion stock purchase that closed in October 2020 as part of the ladiratuzumab vedotin collaboration agreement. The full year in 2020 included $975.1 million in license revenue related to the Merck collaborations for ladiratuzumab vedotin and TUKYSA that were entered into in September 2020.

Cost of Sales: Cost of sales in the fourth quarter were $61.8 million, compared to $11.9 million in the fourth quarter of 2019. Cost of sales were $217.7 million for the full year in 2020, compared to $44.0 million for the same period in 2019. The increases in 2020 were primarily due to the gross profit share payment to Astellas based on PADCEV sales, which were $32.1 million and $104.6 million in the fourth quarter and full year, respectively. Cost of sales for the periods in 2020 also reflect amortization of acquired in-process technology costs that began with the approval of TUKYSA in April 2020, and third-party royalties owed for ADCETRIS, PADCEV and TUKYSA net product sales. Cost of sales for the year in 2020 included a payment owed to a third-party technology licensor related to the TUKYSA license agreement with Merck reflected in the third quarter of the year.

Research and Development (R&D) Expenses: R&D expenses in the fourth quarter were $216.2 million, compared to $201.1 million in the fourth quarter of 2019. R&D expenses were $827.1 million for the full year in 2020, compared to $719.4 million in 2019. The increase in 2020 primarily reflected continued investment in the Company's pipeline.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses in the fourth quarter were $158.4 million, compared to $115.2 million in the fourth quarter of 2019. SG&A expenses were $533.8 million for the full year in 2020, compared to $373.9 million for the same period in 2019. The increases were primarily attributed to increased field sales personnel in the U.S. for Seagen's recently commercialized products, PADCEV and TUKYSA, as well as higher infrastructure costs to support the Company's continued growth and international expansion.

Non-cash share-based compensation cost for the full year in 2020 was $147.2 million, compared to $127.3 million for the same period in 2019.

Net Income / Loss: Net income for the fourth quarter of 2020 was $167.1 million, or $0.90 per diluted share, compared to net income of $25.8 million, or $0.14 per diluted share, for the fourth quarter of 2019. For the full year in 2020, net income was $613.7 million, or $3.37 per diluted share, compared to a net loss of $158.7 million, or $0.96 per diluted share, for the year in 2019. Net income for 2020 was driven by the revenue recognized in the third and fourth quarters under the Merck collaborations. Seagen utilized federal net operating loss carryforwards as allowed, however the Company incurred income taxes in certain states which resulted in an income tax provision of $2.0 million for the year in 2020.

Cash and Investments: As of December 31, 2020, Seagen had $2.7 billion in cash and investments. This includes proceeds from a $1.0 billion equity investment by Merck, which closed in October 2020.
