Seattle Genetics Reports Fourth Quarter and Full Year 2018 Financial Results
Seattle Genetics, Inc. (Nasdaq:SGEN) today reported financial results for the fourth quarter and year ended December 31, 2018. The company also highlighted ADCETRIS (brentuximab vedotin) commercialization and clinical development accomplishments and progress with its late-stage clinical programs for cancer.
“During 2018, we received FDA approval for two ADCETRIS frontline indications, a major accomplishment that significantly expands the number of patients eligible to benefit from treatment. These approvals for frontline advanced Hodgkin lymphoma and CD30-expressing peripheral T-cell lymphoma (PTCL) were based on phase 3 data showing superior efficacy of the ADCETRIS-containing regimens compared to combination chemotherapy agents that have been used for decades,” said Clay Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. “Additionally, we made progress in 2018 with our late-stage clinical programs, leading to important anticipated milestones this year. Notably, we expect to report top-line data in the first quarter of 2019 from the pivotal trial of enfortumab vedotin in metastatic urothelial cancer and to report top-line data later in the year from the pivotal trial of tucatinib in HER2-positive metastatic breast cancer. Taken together, we are positioned to establish ADCETRIS as the standard of care in the frontline setting in both advanced Hodgkin lymphoma and CD30-expressing PTCL, and realize our vision of becoming a company with multiple oncology products addressing unmet medical needs.”
ADCETRIS Program Highlights
- New Indication for CD30-Expressing Frontline PTCL: In November 2018, the U.S. Food and Drug Administration (FDA) approved ADCETRIS in combination with chemotherapy for adults with previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified. The approval is based on the successful outcome of the ECHELON-2 phase 3 clinical trial. The FDA granted Breakthrough Therapy Designation in this setting and reviewed the application under the Real-Time Oncology Review Pilot Program leading to approval less than two weeks after submission of the supplemental Biologics License Application (BLA).
- New Indication in Canada: Health Canada approved ADCETRIS for the treatment of adult patients with primary cutaneous ALCL or CD30-expressing mycosis fungoides who have had prior systemic therapy.
- Multiple Abstracts at ASH: In addition to the presentation of ECHELON-2 data, which were also simultaneously published in The Lancet, ADCETRIS was featured in more than 30 data presentations at the 60th American Society of Hematology (ASH) annual meeting from both corporate and investigator-led clinical trials. The trials highlighted the potential application of ADCETRIS as monotherapy and as part of combination regimens in a range of CD30-expressing lymphomas.
Enfortumab Vedotin (EV) Program Highlights
- EV-201 Pivotal Trial Data in First Quarter 2019: Seattle Genetics and Astellas expect to report top-line data in the first quarter of 2019 from the ongoing EV-201 pivotal trial evaluating EV in patients with locally advanced or metastatic urothelial cancer who previously received both platinum chemotherapy and a checkpoint inhibitor (PD-1 or PD-L1). Data from this trial could serve as the basis for a BLA submission under the FDA’s accelerated approval pathway.
- Multiple Trials Enrolling: Seattle Genetics and Astellas continue enrollment in the global randomized phase 3 clinical trial called EV-301 for patients with locally advanced or metastatic urothelial cancer who were previously treated with a PD-1 or PD-L1 inhibitor and a platinum-containing regimen. EV-301 is intended to support global regulatory submissions for approval and serve as a confirmatory trial in the United States. Additionally, enrollment is ongoing in the phase 1 trial called EV-103 in earlier lines of locally advanced or metastatic urothelial cancer, including first-line, evaluating EV in combination with pembrolizumab and/or platinum agents.
Tucatinib Program Highlights
- HER2CLIMB Pivotal Trial Data in 2019: Seattle Genetics achieved enrollment of 480 patients in the HER2CLIMB pivotal trial to enable analysis of the primary endpoint of PFS, with top-line data expected to be reported in 2019. In addition, HER2CLIMB enrollment is continuing up to 600 patients, to support the analyses of key secondary endpoints, including overall survival as well as progression-free survival in patients with brain metastases. The company anticipates completing enrollment of the additional patients in mid-2019.
Tisotumab Vedotin (TV) Program Highlights
- innovaTV 204 Pivotal Trial Enrollment: Seattle Genetics and Genmab expect to complete enrollment by mid-2019 in the pivotal innovaTV 204 trial evaluating TV in patients with recurrent and/or metastatic cervical cancer who have relapsed or progressed after standard of care treatment.
- Broad Development Program: Seattle Genetics and Genmab are evaluating TV in multiple ongoing or planned clinical trials, including trials in earlier-stage cervical cancer and in multiple types of other solid tumors.
Other Recent Activities
- Initiated Phase 1 Trial of SEA-BCMA: Seattle Genetics announced the dosing of the first patient in a phase 1 trial evaluating the safety and tolerability of SEA-BCMA in relapsed or refractory multiple myeloma. SEA-BCMA is an empowered antibody using the company’s proprietary Sugar Engineered Antibody (SEA) technology designed to enhance antibody dependent cellular cytotoxicity.
- ADC Collaborator Regulatory Submission: In December 2018, Roche submitted regulatory applications in the U.S. and the European Union for approval of polatuzumab vedotin to treat patients with relapsed or refractory diffuse large B-cell lymphoma. Polatuzumab vedotin utilizes Seattle Genetics’ proprietary antibody-drug conjugate (ADC) technology.
FOURTH QUARTER AND FULL YEAR 2018 FINANCIAL RESULTS
Revenues: Total revenues in the fourth quarter and year ended December 31, 2018 increased to $174.5 million and $654.7 million, respectively, compared to $129.6 million and $482.3 million for the same periods in 2017. Revenues are comprised of the following three components:
- Product Revenues: ADCETRIS net sales in the U.S. and Canada for the fourth quarter were $132.1 million, a 58 percent increase over net sales of $83.7 million in the fourth quarter of 2017. ADCETRIS net sales in the U.S. and Canada were $476.9 million for the full year in 2018, a 55 percent increase over net sales of $307.6 million for the same period in 2017. Growth over 2017 reflects ADCETRIS label expansions in 2018, most notably in frontline Stage III and IV Hodgkin lymphoma in March 2018 and to a lesser degree in frontline CD30-expressing PTCL in November 2018.
- Royalty Revenues: Royalty revenues in the fourth quarter were $24.6 million, compared to $20.0 million in the fourth quarter of 2017. Royalty revenues were $83.4 million for the full year in 2018, compared to $66.1 million for the same period in 2017. Royalty revenues are primarily driven by sales of ADCETRIS outside the U.S. and Canada by Takeda.
- Collaboration and License Agreement Revenues: Amounts earned under the company’s ADCETRIS and ADC collaborations were $17.8 million in the fourth quarter and $94.4 million for the full year in 2018, compared to $25.9 million and $108.6 million, respectively, for the same periods in 2017.
Research and Development (R&D) Expenses: R&D expenses in the fourth quarter were $149.8 million, compared to $110.5 million in the fourth quarter of 2017. R&D expenses were $565.3 million for the full year in 2018, compared to $456.7 million for the same period in 2017. The increase in 2018 reflects increased investment in the company's late-stage pipeline and technology acquisition costs in the first quarter of 2018.
