Unaudited preliminary 2019 results include:

$43.2 million in estimated ELZONRIS net revenues for the year-ended December 31, 2019
$11.8 million in estimated ELZONRIS net revenues for the fourth quarter of 2019
The above financial information is based on preliminary unaudited information, is subject to adjustment, and does not present all information necessary for an understanding of the Company’s full-year and fourth quarter financial results for 2019. Stemline expects to report complete audited 2019 financial results on or before March 16, 2020.

Robert Francomano, Chief Commercial Officer of Stemline, stated, "We are very pleased with the solid uptake seen in the first year of the ELZONRIS launch, as we continue to successfully create, penetrate and grow a new market in BPDCN. Given the orphan nature and unique features of this disease, we believe patient starts were subject to significant quarterly variance – a phenomena that will likely continue throughout 2020. We are actively implementing a host of tactics to expand and further penetrate this emerging market."

Ivan Bergstein, CEO of Stemline, commented, "2019 was a transformational year for Stemline as we launched ELZONRIS, the first and only CD123 targeted agent and first agent ever approved for patients with BPDCN. We continue to pursue growth opportunities not only in BPDCN but also in a number of malignancies where targeting CD123 could provide therapeutic benefit. We look forward to data readouts in CMML, MF, and AML, including in patient subsets with high CD123, later this year and on into next year. Given our continued commercial and clinical progress, we look forward to a productive 2020 and beyond."

About ELZONRIS
ELZONRIS (tagraxofusp), a CD123-directed cytotoxin, is approved by the U.S. Food and Drug Administration (FDA) and commercially available in the U.S. for the treatment of adult and pediatric patients, two years or older, with blastic plasmacytoid dendritic cell neoplasm (BPDCN). For full prescribing information in the U.S., visit www.ELZONRIS.com. In Europe, a marketing authorization application (MAA) is under review by the European Medicines Agency (EMA). ELZONRIS is also being evaluated in additional clinical trials in other indications including chronic myelomonocytic leukemia (CMML), myelofibrosis (MF), and acute myeloid leukemia (AML).

About BPDCN
BPDCN is an aggressive hematologic malignancy with historically poor outcomes and an area of unmet medical need. BPDCN typically presents in the bone marrow and/or skin and may also involve lymph nodes and viscera. The BPDCN cell of origin is the plasmacytoid dendritic cell (pDC) precursor. The diagnosis of BPDCN is based on the immunophenotypic diagnostic triad of CD123, CD4, and CD56, as well as other markers. For more information, please visit the BPDCN disease awareness website at www.bpdcninfo.com.

About CD123
CD123 is a cell surface target expressed on a wide range of myeloid tumors including blastic plasmacytoid dendritic cell neoplasm (BPDCN), certain myeloproliferative neoplasms (MPNs) including chronic myelomonocytic leukemia (CMML) and myelofibrosis (MF), acute myeloid leukemia (AML) (and potentially enriched in certain AML subsets), myelodysplastic syndrome (MDS), and chronic myeloid leukemia (CML). CD123 has also been reported on certain lymphoid malignancies including multiple myeloma (MM), acute lymphoid leukemia (ALL), hairy cell leukemia (HCL), Hodgkin’s lymphoma (HL), and certain Non-Hodgkin’s lymphomas (NHL). In addition, CD123 has been detected on some solid tumors as well as autoimmune disorders including cutaneous lupus and scleroderma.

Astellas and Adaptimmune will agree on up to three targets and co-develop T-cell therapy candidates directed to those targets. These targets will exclude target specific T-cell products in pre-clinical or clinical trials or those developed for other partners at Adaptimmune. The collaboration will leverage Adaptimmune’s target identification and validation capabilities for generating target-specific T-cell Receptors (TCRs), chimeric antigen receptors (CARs), and HLA-independent TCRs that recognize surface epitopes independently of the HLA profile of the tumor cell. The collaboration will also utilize Astellas’ Universal Donor Cell and Gene Editing Platform it obtained through the acquisition of Seattle-based Universal Cells.

Adaptimmune has been collaborating with Universal Cells since 2015 on development of gene-edited iPSC cell lines, for which Adaptimmune has rights to develop and commercialize resulting T-cell therapy products using its proprietary process for generating T cells from stem cells without the use of feeder cell lines.

Astellas will fund research up until completion of a Phase 1 trial for each candidate. Upon completion of the Phase 1 trial for each candidate, Astellas and Adaptimmune will elect whether to progress with co-development and co-commercialization of the candidate, or to allow the other Party to pursue the candidate independently through a milestone and royalty bearing licence, with the agreement allowing for either company to opt out. The companies will each have a co-exclusive licence covering the co-development and co-commercialization of the product candidates within the field of T-cell therapy. If a candidate is developed by one company only, the appropriate licences will become exclusive to the continuing party.

"Astellas positions immuno-oncology as one of its strategic areas of primary focus, and it is engaged in the development of novel therapies for cancer patients using a new modality/technology," stated Naoki Okamura, Representative Director Corporate Executive Vice President, Chief Strategy Officer and Chief Financial Officer, Astellas. "In addition to NK cells, T-cells are an important component of cell therapy for immuno-oncology, and we look forward that this agreement with Adaptimmune will enable us to create new stem-cell derived allogeneic T-cell therapies for a variety of cancers, including solid tumors, in the future. We will continue to dedicate our efforts in delivering novel treatments for diseases with high unmet medical needs, pursuing cutting-edge science and technological advances."

"We are delighted to establish this significant co-development partnership with Astellas, which builds upon and substantially extends an existing collaboration focused on gene editing of iPSC cells," said Helen Tayton-Martin, Adaptimmune’s Chief Business Officer and Co-Founder. "This new collaboration may encompass both CAR-T and TCR T-cell approaches, including our novel HLA-independent TCR ("HiT") platform. It brings together highly complementary skills and expertise across the two organizations, and will enable the accelerated development of new, off-the-shelf T-cell therapy products for people with cancer."

Astellas will also have the right to select two targets and develop allogeneic cell therapy candidates independently. Astellas will have sole rights to develop and commercialize these products, subject to necessary licenses and the payment of milestones and royalties.

Under the terms of the agreement, Adaptimmune may receive up to $897.5 million in payments, including:

an upfront payment of $50 million.
development milestones totalling up to $73.75 million for each product if the collaboration product discovered in this partnership is co-developed and commercialized by both companies
Up to $147.5 million in milestone payments per product and up to $110 million in sales milestones for products developed unilaterally by Astellas.
In addition, Adaptimmune will receive research funding of up to $7.5 million per year.

Finally, Adaptimmune would receive tiered royalties on net sales in the mid-single to mid-teen digits.

Under the terms of the agreement, Astellas may receive up to $552.5 million, including:

Up to $147.5 million in milestone payments per product and up to $110 million in sales milestones
for products developed unilaterally by Adaptimmune.
In addition, Astellas would receive tiered royalties on net sales in the mid-single to mid-teen digits.

To the extent that Astellas and Adaptimmune co-develop and co-commercialize any T-cell therapy, they will equally share the costs of such co-development and co-commercialization, with the resulting profits from co-commercialization also shared equally. Further details governing co-development and co-commercialization will be articulated in a product-specific commercialization agreement.

The impact of this transaction on Astellas’ financial results in the fiscal year ending March 31, 2020 will be limited.
