ORDER GRANTING DEFENDANTS’ MOTIONS TO DISMISS1

1 The facts are drawn from the Verified Amended Complaint (the “Amended Complaint”) and documents it incorporates by reference. C.A. No. 2024-0421-KSJM, Docket (“Dkt.”) 39 (Am. Compl.). The director defendants in this action attached Israel Biotech’s marketing presentation and Ayala’s Form 10-Q filing for the third quarter of 2023 as exhibits to their opening brief. Dkt. 50 (“Director Defs.’ Opening Br.”), Exs. A, C. Each document is quoted or explicitly referenced in the Amended Complaint and thus incorporated by reference. Freedman v. Adams, 2012 WL 1345638, at *5 (Del. Ch. Mar. 30, 2012) (“When a plaintiff expressly refers to and 1. Ayala Pharmaceuticals, Inc. (the “Company”) is a Delaware corporation

focused on developing cancer treatments. Israel-based venture capital funds

Defendants Israel Biotech Fund I, L.P. and Israel Biotech Fund II, L.P. (together,

“Israel Biotech”) invested in Ayala in 2017. In April 2018, Israel Biotech led a Series

A financing round. In connection with the financing, Israel Biotech appointed non-

party Roni Mamluk as CEO, Defendant and Israel Biotech co-founder David

Sidransky as executive chairman, and Defendants Robert Spiegel and Murray

Goldberg to Ayala’s board of directors (the “Board”). In May 2020, Ayala went public

on the NASDAQ stock exchange.

2. By 2021, Ayala was struggling financially. The Company sustained net

losses. Creditors doubted its ability to continue as a going concern. Sidransky was a

board member of Advaxis, Inc., another struggling biotechnology company, and

introduced the two management teams. Ayala began discussing a merger with

Advaxis in July 2022. The parties announced a merger (the “Advaxis Merger”)

pursuant to a merger agreement dated October 18, 2022.2

3. But Ayala was still in a precarious financial position. The month after

the Advaxis Merger was announced, NASDAQ threatened delisting Ayala because

the Company was not in compliance with stockholders’ equity and minimum bid price

requirements.

heavily relies upon documents in her complaint, these documents are considered to be incorporated by reference into the complaint; this is true even where the documents are not expressly incorporated into or attached to the complaint.”). 2 Am. Compl. ¶ 88.

2 4. Ayala began to consider another merger—this time with Biosight, a

portfolio company of Israel Biotech and another Israel-based venture capital fund,

Defendant Arkin Bio Ventures L.P. (“Arkin”). Ayala and Biosight announced a

merger (the “Biosight Merger”) pursuant to an agreement dated July 26, 2023. The

parties agreed that the board of the merged company would have nine members: four

appointed by Ayala; four appointed by Biosight; and Ayala CEO and Board Chair

Kenneth Berlin. Berlin would be CEO and Chair of the merged entity.

5. After the Biosight Merger, Ayala’s Board comprised Sidransky, Israel

Biotech co-founder Yuval Cabilly, Spiegel, Goldberg, Arkin executive Pini Orbach,

Roni Appel, Vered Bisker-Leib, Bridget Martel, and Berlin (together, “Director

Defendants”). When the Biosight Merger closed on October 19, 2023, Israel Biotech

and Arkin collectively owned approximately 36% of Ayala’s stock.

6. Germane to this litigation, the Amended Complaint identifies Spiegel

and Goldberg as “Venture Advisors” of Israel Biotech.3 In its marketing materials,

Israel Biotech describes Venture Advisors as industry experts that it appoints to its

portfolio company boards.4 Indeed, Spiegel is the former Chief Medical Officer of

pharmaceutical company Schering-Plough, and Goldberg is the former Chief

Financial Officer of pharmaceutical company Regeneron.5 Israel Biotech publicly

touts Venture Advisors as “chang[ing] the equation” in portfolio companies through

5 Director Defs.’ Opening Br., Ex. A at 6.

3 hands-on involvement, including “strategic drug development leadership,”

“recruiting additional key personnel[,]” and “financial help[.]”6

7. Further, a 2019 article quotes Sidransky as explaining that Venture

Advisors are investors in Israel Biotech and have “skin in the game” with respect to

Israel Biotech’s investments.7 And Ayala’s public filings suggest that Spiegel and

Goldberg, as Venture Advisors, are limited partners in Israel Biotech Fund I, L.P.

8. The Biosight Merger did not stem Ayala’s financial difficulties. In

November 2023, the Board announced that without additional funding, it would need

to consider “bankruptcy and liquidation of the Company.”8 The Board simultaneously

explored financing options and engaged in strategic discussions with third parties.

9. On November 16, 2023, the Board met and considered several financing

options, including (i) a potential PIPE financing with third-party investors who had

indicated interest in providing up to $15 million at a 20% discount to market price,

(ii) ongoing strategic transaction discussions with several parties, and (iii) a proposal

for a convertible note issuance jointly presented by Israel Biotech and Arkin.

10. Pursuant to Israel Biotech and Arkin’s proposed transaction, Israel

Biotech, Arkin, and non-party and Ayala stockholder Biotel would lend Ayala up to

$4 million through convertible notes to be exercised at a 50% discount to market price.

The proposed transaction also contemplated granting warrants to Israel Biotech and

4 Arkin, giving them the right to purchase up to 15 million additional shares at a

discount.

11. The Board approved the transaction proposed by Israel Biotech and

Arkin that same day. Further, the Board granted Israel Biotech warrants for 7.5

million additional shares of Company stock at the same discount. The Board also

gave Israel Biotech, Arkin, and Biotel the ability to fund up to approximately $5.5

million in additional convertible notes—also to be exercised at the same 50% discount

(together with the $4 million convertible note issuance, the “Notes Transaction”).

12. After approving the Notes Transaction, Ayala continued to explore

strategic options. On December 6, 2023, an advisory firm proposed an asset sale to

another biotechnology company, Immunome, Inc. Ayala and Immunome entered into

a non-binding term sheet on December 22. Immunome agreed to acquire Ayala’s

assets, and the parties executed an Asset Purchase Agreement on February 5, 2024

(the “Immunome Transaction”). The Immunome Transaction was announced on

February 6, 2024.

13. Two days later, Israel Biotech and Arkin exercised their conversion and

warrant rights. Israel Biotech, Arkin, and Biotel also loaned an additional $2 million
