1 2 3 4 5 6 7 UNITED STATES DISTRICT COURT 8 SOUTHERN DISTRICT OF CALIFORNIA 9 10 ZACHARY SALZMAN, Individually and Case No.: 23-cv-01216-GPC-VET on Behalf of All Others Similarly 11 Situated, ORDER GRANTING IN PART AND 12 DENYING IN PART MOTION TO Plaintiff, DISMISS 13 v. 14 [ECF Nos. 50, 56] IMMUNITYBIO, INC., RICHARD 15 ADCOCK, DAVID C. SACHS, and PATRICK SOON-SHIONG, 16 Defendant. 17

18 ImmunityBio is a pharmaceutical company that develops cancer treatments. Its 19 portfolio includes at least seventeen product candidates, but this dispute concerns just 20 one: the company’s flagship product candidate, an antibody called N-803, known 21 internally as Anktiva. Plaintiff alleges that Defendants,1 in the course of seeking FDA 22 approval for Anktiva, misled investors to believe that Anktiva was manufactured in 23 24 25 1 The Individual Defendants are ImmunityBio’s CEO, CFO, and Chief Scientific and 26 Medical Officer, respectively. ECF No. 37 (“Amended Complaint” or “AC”) at ¶¶ 21– 23. 27 1 compliance with industry standards. In fact, Plaintiff alleges, Defendants knew that 2 Anktiva’s manufacturing process was noncompliant and that it suffered from serious and 3 persistent issues relating to recordkeeping, quality control, basic sanitation standards, and 4 deviation management. 5 Pending before the Court is Defendants’ Motion to Dismiss Plaintiff’s Amended 6 Complaint (“AC”). Defendants argue that Plaintiff has failed to allege either a materially 7 misleading statement or a strong inference of scienter. For the reasons stated below, the 8 motion is GRANTED IN PART AND DENIED IN PART. 9 BACKGROUND 10 The Court recites the relevant facts as provided in the complaint and corroborated 11 by a number of confidential witnesses, taking them to be true and viewing them in the 12 light most favorable to the Plaintiff. 13 Anktiva is a biologic drug, which means that it is produced from living organisms. 14 Because the process can involve microorganisms, plant cells, or even animal cells, 15 manufacturing biologic products is an especially sensitive process, and producing 16 biologic products “at scale requires a series of highly-technical steps . . . to ensure a 17 consistent end product free from impurities.” AC at ¶ 5. Due to the sensitivity of this 18 process, “even minor deviations from normal manufacturing processes can result in 19 significant changes in product composition.” Id. at ¶ 69. Any deviation must “be 20 recorded and justified.” See id. (citing 21 C.F.R. § 211.100). 21 The FDA will not approve a biologic product if its production fails to comply with 22 the FDA’s minimum standards for drug manufacturing, otherwise known as current good 23 manufacturing practices (“cGMP”). Thus, in order to introduce a biologic drug to the 24 market, a company must file a Biologics License Application (“BLA”). A BLA is 25 composed of “data and supporting materials collected in clinical trials, along with other . 26 . . information on the manner in which the product is manufactured.” This includes 27 1 “proposed process and protocols for manufacturing at scale, [and] also must include data 2 generated in connection with previously-produced process performance qualification 3 (‘PPQ’) batches using the stated manufacturing processes and equipment.” Id. at ¶ 43. 4 These qualification studies serve “to validate that the proposed manufacturing process is 5 capable of reproducing results within predetermined specifications at commercial scale.” 6 Id. 7 These studies are further corroborated by an FDA inspector’s pre-approval visit to 8 the manufacturing facility. The inspector “observ[es] the site in operation but also 9 [reviews] appropriate records at the facility reflecting past activities.” Id. at ¶ 46. At the 10 conclusion of an inspection, the inspector may issue a “Form 483,” which 11 “memorialize[s] significant deficiencies observed during the inspection that, in the 12 judgment of the inspector[], constitute violations of FDA regulations, including cGMP.” 13 Id. ¶ 64. “After completing its review, the FDA will either approve the BLA or send the 14 sponsor a complete response letter (‘CRL’). A CRL outlines any issues identified by the 15 FDA during the review that prevent approval of the BLA in its current form and, where 16 possible, recommend actions that a sponsor may take to remedy the issues or otherwise 17 position the application for approval.” Id. at ¶ 48 (citing 21 C.F.R. § 601.3(a)). 18 ImmunityBio “was formed in connection with a merger between two clinical-stage 19 biopharmaceutical companies controlled by Defendant Soon-Shiong on March 9, 2021,” 20 id. at ¶ 2, and submitted its BLA for Anktiva to the FDA on May 23, 2022, id. at ¶ 7. On 21 May 11, 2023, the FDA rejected the BLA. Id. at ¶ 14. Which came as a surprise to most 22 of the company’s shareholders. Anktiva’s Phase 3 clinical trials had been “impressive,” 23 and in the year leading up to the rejection, ImmunityBio had repeatedly touted its 24 manufacturing capabilities. For instance, ImmunityBio had asserted numerous times in 25 press releases and SEC-mandated disclosures that “[t]he company ha[d] established GMP 26 manufacturing capacity at scale.” See, e.g., id. at ¶ 108. It asserted that for its “Anktiva 27 1 product candidate, [it had] contracted with a multi-national biologics manufacturer with 2 multiple cGMP-compliant facilities.” See, e.g., id. at ¶ 102. And it asserted that those 3 “facilities ha[d] robust process development and validation and quality oversight.” Id. 4 But shareholders learned on May 11, 2023, that the FDA had rejected Anktiva’s BLA 5 because of deficient manufacturing practices. To shareholders, the news was shocking. 6 But to company executives, the rejection was nothing more than “business 7 disappointment.” ECF No. 50 at 39. For the signs of manufacturing woe had appeared to 8 leadership more than two years prior, as early as March of 2021. 9 ImmunityBio learned of these deficiencies from its contract manufacturing 10 organization (“CMO”), AGC Biologics, Inc., which manufactured the active ingredient in 11 Anktiva. AGC had originated the technique for producing the active ingredient, and 12 ImmunityBio had continued to entrust the process to AGC, as “it would [have] be[en] 13 exceedingly expensive and risky to transfer th[e] technology in-house, particularly with 14 Phase 3 clinical trials . . . .” AC at ¶ 60. Despite its use of a CMO, ImmunityBio 15 remained “ultimately responsible for the manufacture” of Anktiva, a fact it reminded 16 investors of in its SEC disclosures. ECF No. 50-10 at 6. ImmunityBio maintained a 17 “Quality Agreement” with AGC, whereby AGC notified the company of the “findings of 18 any inspection by a government agency,” including any deviations. AC at ¶ 168. 19 Three times, in the two years preceding the BLA’s rejection, ImmunityBio learned 20 that FDA inspectors had observed conditions at the Anktiva facility that violated federal 21 law. ECF No. 50-3 at 2. AGC was first cited for manufacturing deficiencies in March of 22 2021 during a non-routine FDA inspection. The inspection resulted in a sixteen-item 23 Form 483 that identified numerous deficiencies in Anktiva’s production, including 24 failures “on the part of AGC’s quality unit to adequately investigate deviations, 25 inadequate oversight of manufacturing procedures on the part of the quality unit, lack of 26 adequate documentation for quality control testing, poorly qualified and validated 27 1 manufacturing processes, and gaps in record keeping such that inspectors could not 2 determine whether manufacturing was operating in a state of control.” Id. at ¶ 65.
