NEW YORK, Jan. 04, 2023 (GLOBE NEWSWIRE) -- Y-mAbs Therapeutics, Inc. (the “Company” or “Y-mAbs”) (Nasdaq: YMAB) a commercial-stage biopharmaceutical company focused on the development and commercialization of novel, antibody-based therapeutic products for the treatment of cancer, today announced a strategic restructuring plan designed to extend its cash runway and prioritize resources on the commercialization and potential label extension of DANYELZA and development of the SADA (Self-Assembly DisAssembly (“SADA”) PRIT 2-STEP) technology platform. The Company plans to discuss omburtamab at its upcoming Type A meeting with the FDA; however, the Company has assumed a deprioritization of the omburtamab program, including all indications, in designing its restructuring plan and in its estimates for 2023. In addition, the Company plans to deprioritize other pipeline programs, including activities relating to GD2-GD3 Vaccine and CD33 bispecific antibody constructs, as part of the restructuring plan.

“We believe that this restructuring of the organization aligns our resources to efficiently leverage both the DANYELZA franchise and support development activities for our highly differentiated novel SADA platform, which we view as the key near and long-term potential growth drivers of Y-mAbs. We believe this sharpened focus should propel us through key anticipated milestones, including continuation and potential expansion of the commercialization of DANYELZA for neuroblastoma patients and potential indication expansion,” said Thomas Gad, founder, President, and Interim CEO. “We also look forward to potentially dosing the first patient with GD2-SADA and generating data that we believe could potentially represent a transformative therapeutic option for patients based on the novel mechanism of action of our SADA constructs. We also expect to submit the IND for CD38-SADA targeting non-Hodgkin's lymphoma. We are excited for 2023 and aim at further de-risking our SADA platform while continuing to grow our top line revenue for DANYELZA in the U.S. and adding ex-U.S. sales as we are excited about the potential launch in China after SciClone Pharmaceuticals received an approval late last year. Additionally, we anticipate a Type A meeting with the FDA in January 2023 to discuss the future of omburtamab.”

Mr. Gad continued, “We expect the reduction in our workforce and our revised business plan to result in a reduction in operating expenses and extension of our cash runway into Q1 2026. I want to extend my sincere appreciation and gratitude to all of our colleagues for the work that has brought us to this point, and for their dedication and service to Y-mAbs while striving to develop new treatments for patients with cancer.”

Strategic Objectives for 2023 and Beyond

  • Aiming to drive growth for our commercial drug, DANYELZA in the US through market growth and potential label expansion to target an estimated US market opportunity of $400 million for high-risk neuroblastoma and osteosarcoma alone
  • Seeking initial validation of the tumor binding capability of our novel SADA platform in solid tumors in the GD2-SADA multicenter trial through the collection of imaging data in patients with small-cell lung cancer, sarcoma, and malignant melanoma
  • Targeting an IND submission in Q2 2023 for CD38-SADA construct against non-Hodgkin's lymphoma to potentially validate SADA in blood cancers
  • Seeking partnerships based on the SADA technology platform
  • Discussing potential regulatory pathway for omburtamab at Type A meeting with the FDA

2023 Financial Outlook

  • The restructuring plan announced today is expected to result in a reduction of Y-mAbs workforce by approximately 35% by the end of May 2023
  • Operating expenses, including restructuring costs which are expected to be recognized in Q1 2023, are expected to decrease by approximately 28% to $115-120 million, compared to previously announced 2022 guidance for operating expenses of $162-167 million
  • As a result of the estimated decrease in operating expenses, we estimate that our cash and cash equivalents should support our operations as currently planned, taking into account the restructuring plan, into the first quarter of 2026
  • The total cash burn for the 2023 fiscal year is expected to be in the range of $50-55 million, which is based on an expected 2022 year-end cash position of approximately $106 million
  • Estimated DANYELZA net product revenues for the 2023 fiscal year are expected to be between $60-65 million, compared to approximately $47-48 million expected for fiscal year 2022

Researchers at Memorial Sloan Kettering Cancer Center (“MSK”) developed DANYELZA, which is exclusively licensed by MSK to Y-mAbs. MSK has institutional financial interests related to the compound and Y-mAbs.
