November 11, 2021

Combined company, to be named Biosight Therapeutics, expected to be well-positioned to leverage its compelling oncology therapeutics pipeline, strong cash position, and accomplished management and Board to maximize stockholder value

Advaxis’ stockholders are urged to vote in support of each proposal presented at Advaxis’ Special Meeting on November 16, 2021


AIRPORT CITY, Israel, November 11, 2021 /PRNewswire/ -- Biosight Ltd., a pharmaceutical development company developing innovative therapeutics for hematological malignancies and disorders, today issued the following statement from its Chairman, Pini Orbach, PhD.

To Advaxis Stockholders:

I am reaching out to you to share our excitement over Biosight’s proposed merger with Advaxis, Inc. (Nasdaq: ADXS) and explain why we believe the transaction represents a mutually compelling opportunity for both companies as well as their stockholders.

We, the Biosight team, have strong conviction in the vast opportunities for our own franchise which is driven by our phase IIb investigational drug, aspacytarabine, that seeks to address unmet medical needs of certain cancer patients by enabling a high-dose antineoplastic drug with minimal systemic toxicity across multiple forms of leukemic cancer. Therefore, we did not enter into a merger agreement lightly and we negotiated what we believe is a fair apportionment of relative value between Biosight and Advaxis.

We understand some Advaxis stockholders may have questions about their expected relative ownership of the combined company, yet this primarily reflects each company’s beliefs about the relative risk of the two parties and their respective clinical programs. Additionally, as indicated in the proxy statement dated October 21, 2021 (as supplemented), the transaction is the product of a strategic review process by both parties, was negotiated at arm’s length, and the consideration to be paid by Advaxis is supported by a fairness opinion from an external advisor issued to Advaxis’ Board. 

We do believe Advaxis’ HOT platform has the potential to improve the lives of people diagnosed with cancer, but we also recognize that Advaxis’ current drug development efforts are at a relatively early stage, require significant capital to advance, have a long time horizon, and face the risk of failing to ultimately obtain regulatory approval. We believe these factors, and Advaxis’ substantial clinical and financial risk more generally, are reflected in its current market capitalization.

Clinical setbacks for public companies often require management teams to make difficult funding decisions to keep their programs advancing. Advaxis stockholders have experienced this over the recent period of pipeline rejuvenation that has led to the HOT programs. Investors willing to provide capital at this juncture typically seek to be compensated for taking this risk in the form of steeper discounts that result in increased dilution relative to companies with later stage assets such as aspacytarabine. On the other hand, as the recently announced PIPE financing demonstrates, by adding a later stage drug like aspacytarabine to the mix, it is possible to attract capital on more favorable terms to the company.

We believe that aspacytarabine’s more advanced clinical stage, more robust clinical dataset, and more clear market opportunity provide enhanced visibility for investors. This enhanced visibility allows investors to construct a viable, long-term, investment thesis for the new, public Biosight Therapeutics. As a result of the merger, Advaxis stockholders will be a part of a more broadly based and well capitalized publicly traded company with a better diversified risk profile. Over the long run, this improved corporate profile may command a reduced cost of capital from institutional investors.

The relative valuations of the proposed merger reflect the significant value Biosight is contributing. The combined company’s pipeline will provide stockholders not only with multiple shots on goal but also includes programs that are much more advanced - and hence, closer to potential commercialization - than anything Advaxis is working on alone.

Furthermore, Advaxis recently announced that, contingent on the merger closing, the company has received commitments of $21 million in financing necessary to advance its clinical development programs. We now expect the cash balance of the combined company, including this proposed financing, to be at least $70M at the time of merger closing which we expect will take us into the second half of 2023 and would allow us to potentially achieve key clinical milestones with aspacytarabine that we believe will create greater short- and long-term value for all stockholders. 

In our view, it is clear that the proposed merger of Advaxis and Biosight is preferable for all parties involved, as we believe it represents a superior outcome compared to both a stand-alone Advaxis and stand-alone Biosight. It has the potential to create a Win/Win/Win scenario as it benefits both Advaxis and Biosight and their respective stockholdrs, and may benefit cancer patients desperately in need of alternative treatments not currently available.

We therefore urge all Advaxis stockholders not to miss this unique opportunity and to support the merger which we believe establishes a much more attractive and differentiated company by which to generate long-term stockholder value.

About Aspacytarabine (BST-236)

Aspacytarabine is a novel proprietary anti-metabolite. It is composed of cytarabine covalently bound to asparagine, acting as a pro-drug of cytarabine. Cytarabine serves as the backbone of AML therapy for over 45 years due to its superior efficacy, however, it is associated with severe bone marrow, gastrointestinal, and neurological toxicities, which significantly limit its use, especially in older and medically compromised patients. Due to its unique pharmacokinetics and metabolism, aspacytarabine enables high-dose therapy with lower systemic exposure to free cytarabine and relative sparing of normal tissues. As such, aspacytarabine may serve as a new therapy for AML and other hematological malignancies and disorders, including for older adults who are unfit for intensive therapy.

Aspacytarabine was granted FDA Fast Track Designation for treatment of AML patients unfit for standard chemotherapy, and FDA and EMA Orphan Drug Designations, which entitle Biosight to seven and ten years of market exclusivity in the U.S. and Europe, respectively, upon aspacytarabine marketing approval for the treatment of AML in each territory.

Interim results from an ongoing Phase 2b study evaluating aspacytarabine as a single-agent first-line AML therapy demonstrate safety and single-agent activity, and additional studies are ongoing to evaluate aspacytarabine as a second line treatment for patients with relapsed or refractory MDS or AML. For more information regarding the Phase 2b clinical study of BST-236, please visit

About Biosight Ltd.

Biosight is a private Phase 2 clinical stage biotech company developing innovative therapeutics for hematological malignancies and disorders. Biosight’s lead product, aspacytarabine (BST-236), is an innovative proprietary anti-metabolite which addresses unmet medical needs by enabling high-dose chemotherapy with reduced systemic toxicity. Aspacytarabine is currently being investigated as a single agent in a Phase 2b clinical trial, recently completed enrollment, for the first-line treatment of AML. Interim results demonstrate tolerability with promising efficacy in the challenging population of AML patients unfit for intensive standard-of-care chemotherapy. Additional Phase 2 studies are ongoing in patients with relapsed/refractory AML and MDS, including a study in collaboration with the European cooperative group, Groupe Francophone des Myélodysplasies (GFM).
