Management to host conference call and webcast today at 8:00 a.m. ET

BUFFALO, N.Y., Aug. 05, 2021 (GLOBE NEWSWIRE) -- Athenex, Inc., (NASDAQ:ATNX), a global biopharmaceutical company dedicated to the discovery, development, and commercialization of novel therapies for the treatment of cancer and related conditions, today provided a corporate and financial update for the second quarter ended June 30, 2021.

"During the second quarter, we held a Type A meeting with the FDA to discuss the path forward for oral paclitaxel and encequidar in metastatic breast cancer and the deficiencies that were raised in the Complete Response Letter (CRL) we received in February," said Johnson Lau, Chief Executive Officer of Athenex. "The FDA has indicated that a well-designed and well-conducted trial may adequately address these deficiencies. We are now evaluating the optimal design for a new clinical study which we plan to present to the FDA in the fourth quarter of 2021. We are continuing to advance oral paclitaxel in angiosarcoma towards registration."

"Our acquisition of Kuur Therapeutics and its innovative allogeneic CAR-NKT technology was a strategically important development for Athenex and we believe it has the potential to unlock tremendous value," continued Dr. Lau. "Kuur's technology, combined with our TCR program, could propel us into a leadership position in cell therapy. We are pleased with the smooth integration of the Kuur team and operations to date and look forward to providing further updates as the programs advance."

Second Quarter 2021 and Recent Business Highlights

Clinical Programs

Oral Paclitaxel and Encequidar

Athenex held a Type A meeting with the US Food & Drug Administration (FDA) regarding the New Drug Application (NDA) for oral paclitaxel in metastatic breast cancer during second quarter 2021. The Company is evaluating the optimal design for a new clinical study which it plans to present to the FDA in 4Q 2021.
An abstract "Phase 1 Study with Expansion Cohorts to Assess the Safety, Tolerability, and Activity of oral paclitaxel + encequidar in Combination with Pembrolizumab in Subjects with Advanced Solid Malignancies" has been accepted for e-Poster presentation at the European Society for Medical Oncology (ESMO) Congress 2021.

Cell Therapy

Presented data from a Phase 1 study (GINAKIT2) of KUR-501 in neuroblastoma at the annual meeting of the American Society of Gene and Cell Therapy (ASGCT) 2021. The data showed one complete response and one partial response out of 11 evaluable and heavily pre-treated pediatric neuroblastoma patients. The therapy was well tolerated with only one Grade 2 CRS.
Continued to enroll patients in a Phase 1 study (ANCHOR) evaluating KUR-502 in patients with relapsed/refractory CD19 positive malignancies including B cell lymphomas, acute lymphoblastic leukemia (ALL), and chronic lymphocytic leukemia (CLL).
Received IRB approval to conduct a Phase 1 trial of TCRT-ESO-A2 (high-affinity TCR-T targeting NY-ESO-1 positive solid tumors).

Commercial Update

Klisyri® (tirbanibulin)

Almirall, S.A. (BLM: ALM), Athenex's partner, received marketing authorization of Klisyri^® from the European Commission in July 2021 for the topical treatment of actinic keratosis (AK) on the face or scalp in adults. The approval followed receipt of a positive opinion from the CHMP of the European Medicines Agency in May 2021.
Athenex entered into license agreements for tirbanibulin with Seqirus (a subsidiary of CSL Limited) and AVIR Pharma, expanding its international commercial partnerships for tirbanibulin in Australia and New Zealand, and Canada, respectively.

Second Quarter 2021 Financial Highlights

Revenues from product sales decreased to $21.4 million for the three months ended June 30, 2021, from $40.2 million for the three months ended June 30, 2020, a decrease of $18.8 million or 47%. This decrease was attributable to a decline in APD product sales of $20.4 million primarily as the result of a decrease in demand for COVID-19 related drugs from the prior year, including some significant non-recurring orders of approximately $14.1 million. In addition, in the first half of 2021, we experienced significant COVID-related challenges in our Indian supply chain and to a lesser extent in China. As a result, we were not able to receive some inventory from our partners located in these regions for a certain period of time. The Company also experienced a higher amount of product sales in 2020 as we started fulfilling demand for certain drugs used to treat patients hospitalized with COVID and demand for FDA shortage products. As a result, the product revenues in the second quarter of last year were particularly high, given the COVID pandemic had just started. Fluctuations in the infection rate and the spread of the global health pandemic and market demand may continue to significantly affect our product sales in the future. These were partially offset by an increase in 503B and contract manufacturing revenue of $1.5 million and $0.4 million, respectively.

License fees and other revenue increased by $0.5 million for the three months ended June 30, 2021. This increase was primarily due to $0.2 million grant revenue and $0.2 million in royalties received from Almirall for the sales of Klisyri® after the product launch in the U.S. in February 2021.

Cost of sales for the three months ended June 30, 2021 totaled $19.7 million, a decrease of $13.3 million, or 40%, as compared to $33.0 million for the three months ended June 30, 2020. The decrease was primarily due to a decrease of $13.1 million in cost of APD product sales, generally in-line with the decrease in the product sales revenue. Additionally, cost of sales related to royalties for license income decreased by $1.2 million from the royalty payment incurred in 2020 on the license revenue from Xiangxue. Cost of 503B product sales increased by $1.3 million as production levels increased.

R&D expenses for the three months ended June 30, 2021 totaled $21.1 million, a decrease of $0.9 million, or 4%, as compared to $22.0 million for the three months ended June 30, 2020. This was primarily due to a decrease in regulatory costs, clinical operations, and preclinical operations. The decrease in these items was partially offset by increases in oral paclitaxel and encequidar API costs in preparation for product launch, together with increases in drug licensing costs, R&D related compensation expenses, and costs related to 503B and cell therapy development.

SG&A expenses for the three months ended June 30, 2021 totaled $21.2 million, an increase of $3.7 million, or 21%, as compared to $17.5 million for the three months ended June 30, 2020. This was primarily due to increase in professional fees and other expenses related to the acquisition of Kuur, increases in compensation related costs, change in fair value of contingent consideration and operating costs including insurance costs and IT costs. These increases were partially offset by a decrease in costs for preparing to commercialize Oral Paclitaxel as significant pre-launch activities occurred in 2020 and slowed upon receipt of the CRL in February 2021.

Interest expense totaled $5.7 million and $1.6 million for the three months ended June 30, 2021 and 2020, respectively. Interest expense in the current period was incurred from the Senior Credit Agreement with Oaktree, while interest expense in the prior period was primarily incurred from debt under a former credit agreement with Perceptive Advisors LLC and its affiliates.

Income tax benefit for the three months ended June 30, 2021 amounted to $11.0 million, compared to income tax expense of $0.1 million for the same period in 2020. The income tax benefit in the current year is primarily the result of taxable temporary difference due to the deferred tax liability recognized for the indefinite lived intangible assets acquired in connection with the acquisition of Kuur's IPR&D. This taxable temporary difference is considered a source of taxable income to support the realization of deferred tax assets from the acquirer which resulted in a reversal of our valuation allowance.

Net loss attributable to Athenex for the three months ended June 30, 2021 was $34.3 million, or ($0.33) per diluted share, compared to a net loss of $40.5 million, or ($0.50) per diluted share, in the same period last year.

As of June 30, 2021, the Company had cash and cash equivalents of $76.9 million, restricted cash of $16.5 million, and short-term investments of $53.3 million.

For further details on the Company's financial results, including the results for the six months ended June 30, 2021, refer to the Form 10Q to be filed with the SEC.

Financial Guidance

In terms of product sales guidance, the Company is limiting financial guidance to the existing Athenex product portfolio only. In 2020, the Company recorded a significant amount of revenues from international customers as a result of the global pandemic. However, it does not see these revenues as recurring in nature. The Company continues to expand its product portfolio. The Company is affirming the guidance it provided on May 6, 2021, as it currently expects its product sales in 2021, excluding any royalties from Klisyri^®, to be in line with 2020 levels.

Cash Conservation Update

As of June 30, 2021, the Company had cash and cash equivalents, restricted cash and short-term investments of $146.7 million. Given uncertainty stemming from the CRL for oral paclitaxel, the Company identified and adopted certain cash conservation measures. Considering these initial measures, and based on our current operating plan, the Company now expects that its cash and cash equivalents, restricted cash and short-term investments as of June 30, 2021, will enable it to meet its current operational liquidity needs and fund operations into 4Q 2022.
