Amendment Description	On April 16, 2024, Ayala Pharmaceuticals, Inc. (“New Ayala,” “Advaxis,” the “Company,” “we,” “us,” “our” and similar references) filed its Annual Report on Form 10-K for the year ended December 31, 2023 (the “Original Filing”), with the Securities and Exchange Commission (the “Commission”). The Company indicated that it would incorporate Part III of Form 10-K in the Original Filing by reference to the Company’s definitive proxy statement for its 2024 annual meeting of stockholders. Because the Company does not anticipate filing its definitive proxy statement by April 29, 2024, the Company is filing this Amendment No. 1 (this “Amendment”) on Form 10-K/A, which amends and restates items identified below with respect to the Original Filing and provides the disclosure required by Part III of Form 10-K.
