-Biologics License Application Submitted to FDA for Enfortumab Vedotin to Treat Advanced or Metastatic Urothelial Cancer Based on Results from the EV-201 Pivotal Trial-

BOTHELL, Wash. — July 16, 2019 — Seattle Genetics, Inc. (Nasdaq:SGEN) today reported financial results for the second quarter and six months ended June 30, 2019. The company also highlighted ADCETRIS (brentuximab vedotin) commercialization and clinical development accomplishments and progress with its late-stage clinical programs for cancer.
“In the second quarter, we achieved record ADCETRIS net sales in the U.S. and Canada, reflecting growth in frontline CD30-expressing peripheral T-cell lymphomas as well as frontline advanced Hodgkin lymphoma,” said Clay Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. “We are also making substantial progress with our late-stage programs, delivering on several key goals. The Biologics License Application for enfortumab vedotin was submitted to the FDA for patients with locally advanced or metastatic urothelial cancer, taking us another step closer to becoming a multi-product oncology company. Additionally, we expect to report topline data from the tucatinib pivotal trial, HER2CLIMB, in HER2-positive metastatic breast cancer later this year and from the tisotumab vedotin pivotal trial, innovaTV 204, in metastatic cervical cancer in the first half of 2020.”

Program Highlights
Ex-U.S. Approvals for ADCETRIS in Frontline Hodgkin Lymphoma (HL): In May 2019, ADCETRIS in combination with AVD (Adriamycin®, vinblastine and dacarbazine) was approved by Health Canada for patients with previously untreated stage IV HL. Also, in June 2019, Takeda received an additional approval for ADCETRIS in frontline HL that resulted in a $7.5 million milestone payment to Seattle Genetics.
Additional Analyses of ECHELON-1 and ECHELON-2 Trials Presented at 2019 American Society of Clinical Oncology (ASCO) Annual Meeting: A three-year update of the ECHELON-1 trial continued to show superior clinical activity of ADCETRIS in combination with AVD compared to ABVD (Adriamycin, bleomycin, vinblastine and dacarbazine) in frontline stage III and IV HL. Separately, analyses of clinical trials in T-cell lymphomas, including the ECHELON-2 trial, showed that responses were observed in patients across all levels of CD30 expression.
Enfortumab Vedotin
Enfortumab Vedotin Biologics License Application (BLA) Submitted to FDA: In July 2019, Seattle Genetics and Astellas Pharma, Inc. submitted a BLA to the U.S. Food and Drug Administration (FDA) for enfortumab vedotin to treat patients with locally advanced or metastatic urothelial cancer who have received a PD-1/L1 inhibitor and who have received a platinum-containing chemotherapy in the neoadjuvant/adjuvant, locally advanced or metastatic setting. The submission is based on positive results

from the first cohort of the EV-201 clinical trial, which were recently presented in a late-breaking oral session at the 2019 ASCO Annual Meeting.
Broad Clinical Development Program Underway: Seattle Genetics and Astellas are evaluating enfortumab vedotin in several ongoing trials. These include a phase 3 randomized clinical trial (EV-301) that is intended to support global registrations. A phase 1 trial (EV-103) is also underway evaluating enfortumab vedotin in earlier lines of treatment for patients with locally advanced or metastatic urothelial cancer, including in combination with pembrolizumab and/or platinum chemotherapy in newly diagnosed patients as well as patients whose cancer progressed from earlier-stage disease. The company expects to report initial data from the EV-103 trial in 2019.
Tucatinib HER2CLIMB Pivotal Trial Data Expected in 2019: The company previously announced enrollment of 480 patients in the HER2CLIMB pivotal trial of tucatinib in HER2-positive metastatic breast cancer to enable analysis of the primary endpoint of progression-free survival (PFS). Topline data are expected to be reported in 2019.
Tisotumab Vedotin
Tisotumab Vedotin innovaTV 204 Pivotal Trial Data Expected in 2020: Seattle Genetics and Genmab previously reported the completion of enrollment in the innovaTV 204 pivotal trial of tisotumab vedotin in patients with recurrent and/or metastatic cervical cancer who have relapsed or progressed after standard of care treatment. Topline data from the trial are expected in the first half of 2020.
Other Recent Activities
Collaborator ADC Progress: In June 2019, the FDA approved Polivy™ (polatuzumab vedotin-piiq) an antibody-drug conjugate (ADC) targeting CD79b that utilizes Seattle Genetics’ technology. Polivy was developed and will be commercialized by Genentech, a member of the Roche Group. As a result, Seattle Genetics will receive a $5.0 million milestone payment and is eligible to receive royalties on worldwide net sales.
Robin Taylor, Ph.D., Appointed Chief Commercial Officer: Dr. Taylor brings 18 years of biotechnology and pharmaceutical company experience in the commercialization of oncology drugs, including significant marketing, launch and global product strategy roles at both Genentech/Roche and AstraZeneca. He contributed to several leading global brands, including Tecentriq® (atezolizumab), Alecensa® (alectinib), Avastin® (bevacizumab) and Herceptin® (trastuzumab).

Revenues: Total revenues in the second quarter and six-month periods ended June 30, 2019 increased to $218.4 million and $413.6 million, respectively, compared to $170.2 million and $310.8 million for the same periods in 2018. Revenues are comprised of the following three components:
Net Product Sales: ADCETRIS net sales for the U.S. and Canada in the second quarter were $159.0 million, a 30 percent increase over net sales of $122.4 million in the second quarter of 2018. ADCETRIS net sales for the U.S. and Canada were $294.0 million for the year-to-date in 2019, a 35 percent increase over net sales of $217.8 million for the same period in 2018.
Royalty Revenues: Royalty revenues in the second quarter were $23.3 million, compared to $20.6 million in the second quarter of 2018. Royalty revenues were $39.0 million for the year-to-date in 2019, compared to $36.2 million for the same period in 2018. Royalty revenues are primarily driven by sales of ADCETRIS outside the U.S. and Canada by Takeda, which increased for the periods in 2019 compared to the same periods in 2018.
Collaboration and License Agreement Revenues: Amounts earned under the company’s ADCETRIS and ADC collaborations increased to $36.1 million in the second quarter of 2019, compared to $27.2 million for the same period in 2018. Collaboration revenues were $80.7 million for the year-to-date in 2019, compared

to $56.7 million for the same period in 2018. Collaboration revenues included the earned portion of $12.5 million and $42.5 million for milestones achieved in the second quarter of 2019 and first half of 2019, respectively. These milestones were based on Takeda’s additional approvals of ADCETRIS in frontline HL and Genentech’s FDA approval of Polivy.
Research and Development (R&D) Expenses: R&D expenses in the second quarter were $163.9 million, compared to $122.9 million in the second quarter of 2018. R&D expenses were $322.2 million for the year-to-date in 2019, compared to $275.4 million for the same period in 2018. The increases reflect additional investment in the company’s late-stage pipeline including enfortumab vedotin, tucatinib and tisotumab vedotin.
Selling, General and Administrative (SG&A) Expenses: SG&A expenses in the second quarter were $82.3 million, compared to $58.3 million in the second quarter of 2018. SG&A expenses were $162.6 million for the year-to-date in 2019, compared to $124.5 million for the same period in 2018. The increases were primarily attributed to costs to support commercialization efforts related to frontline ADCETRIS indications, the company's late-stage programs and higher infrastructure costs to support the company's continued growth.
Non-cash, share-based compensation cost for the first six months of 2019 was $51.9 million, compared to $32.4 million for the same period in 2018.

Net Loss
Net loss for the second quarter of 2019 was $79.2 million, or $0.49 per diluted share, compared to net income of $76.3 million, or $0.47 per diluted share, for the second quarter of 2018. Net loss in the second quarter of 2019 included a net investment loss of $40.5 million primarily associated with Seattle Genetics’ common stock holdings, which are marked-to-market, compared to a net investment gain of $106.6 million in the second quarter of 2018. For the six months ended June 30, 2019, net loss was $92.6 million, or $0.57 per share, compared to a net loss of $35.4 million, or $0.23 per share, for the six months ended June 30, 2018. Net loss for the six months ended June 30, 2018 included an investment gain of $88.7 million.

Cash and Investments
