SELLAS Life Sciences Group, Inc. current report, 19 December 2023

Business Context and Reporting Period

This Form 8-K was filed by SELLAS Life Sciences Group, Inc. on December 22, 2023, reporting events occurring on December 19, 2023. The filing addresses a dispute under an exclusive license agreement with 3D Medicines Inc. regarding the development and commercialization of galinpepimut-S (GPS) and GPS+ in mainland China, Hong Kong, Macau, and Taiwan.

Key Financial Metrics

The filing does not provide specific financial statements, revenue, profit, cash flow, or liquidity metrics. The only financial figure disclosed relates to a contractual dispute involving two development milestone payments totaling $13.0 million that the Company expects to be due from 3D Medicines.

Material Changes and Dispute Details

The Company and 3D Medicines are engaged in a dispute regarding the trigger and payment of the $13.0 million in milestone payments. The disagreement stems from 3D Medicines enrolling patients in the REGAL Study in Taiwan prior to the second half of 2023, whereas the Company expected enrollment in mainland China to trigger the payments. Additionally, the Company alleges 3D Medicines failed to use commercially reasonable best efforts to develop GPS in mainland China. Negotiations over the last three to four months have failed to resolve the matter.

Outlook, Risks, and Unusual Items

SELLAS has commenced a binding arbitration proceeding administered by the Hong Kong International Arbitration Centre, governed by New York State law. The Company states it cannot predict the outcome of the arbitration, the timing of any potential receipt of milestone payments, or the recovery of other damages sought. This legal action represents a significant contingency affecting potential future cash flows.
