Opinion

UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF NEW YORK JOHN ALOISIO, as Executor of the Estate of Elizabeth Aloisio, Deceased, Plaintiff, 25 Civ. 7997 (KPF) -v.- OPINION AND ORDER STIFTUNG AKTION

KNOCHENMARKSPENDE BAYERN, Defendant. KATHERINE POLK FAILLA, District Judge:1 Elizabeth Aloisio passed away after a bone marrow transplant intended to cure her leukemia went tragically awry. Through a German stem cell database foundation, by way of the National Marrow Donor Program (“NMDP”) in Minnesota, Ms. Aloisio had secured what she thought was a life-saving match with a donor. But after her doctors in New York administered the transplant, Ms. Aloisio learned that a labeling error had caused her to receive the wrong cells. A painful battle with graft-versus-host disease (“GVHD”) ensued, and she succumbed to her illnesses a year later. Ms. Aloisio’s brother, Plaintiff John Aloisio, brought this action on her behalf against the stem cell database foundation, Stiftung Aktion Knochenmarkspende Bayern (“AKB” or “Defendant”),2 alleging claims of, inter

1 Ty Greenberg, a rising second-year student at New York University School of Law and an intern in my Chambers, provided substantial assistance in researching and drafting this Opinion. 2 Plaintiff filed his complaint against AKB Foundation and AKB Stiftung Aktion Knochenmarkspende Bayern. (Dkt. #1-1). Upon consent of the parties, the Court alia, negligence and wrongful death under New York common law. Before the Court is Defendant’s motion to dismiss Plaintiff’s Complaint pursuant to Federal Rule of Civil Procedure 12(b)(2) for lack of personal jurisdiction and

Rule 12(b)(5) for insufficient service of process. For the reasons set forth below, the Court grants Defendant’s motion and dismisses all claims against it. BACKGROUND3 A. Factual Background 1. Ms. Aloisio Is Diagnosed with Leukemia, Locates a Stem Cell Donor, and Is Infused with the Wrong Stem Cells In October 2018, Ms. Aloisio was diagnosed with leukemia. (Compl. ¶ 7). Her physician recommended that she receive a stem cell transplant, initiating a search for possible donors. (Id.). The NMDP worked with international partners, including German-based donor registry Zentrale Knochenmarkspender-Register fuer die Bundesrepublik Deutschland (“ZKRD”),

amended the case caption to name only Stiftung Aktion Knochenmarkspende Bayern as Defendant. (Dkt. #22). 3 This Opinion draws its facts from the Complaint (“Compl.” (Dkt. #1-1)), the well-pleaded allegations of which are taken as true for purposes of this Opinion. See Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). While Plaintiff requests, without supporting authority, that the Court discount the Declaration of Prof. Ernst Holler (“Holler Decl.” (Dkt. #15)) because “the words of interested parties should not be allowed to obviate the discovery process and foreclose plaintiff’s claims” (Pl. Opp. 20-21), the Court also relies, as appropriate, on this declaration filed in support of Defendant’s motion to dismiss, and which declaration was uncontroverted in Plaintiff’s opposition, see MacDermid, Inc. v. Deiter, 702 F.3d 725, 727 (2d Cir. 2012) (explaining that on a Rule 12(b)(2) motion, “[t]he allegations in the complaint must be taken as true to the extent they are uncontroverted by the defendant’s affidavits” (internal quotation marks and citation omitted)); Dorchester Fin. Sec., Inc. v. Banco BRJ, S.A., 722 F.3d 81, 83, 86 (2d Cir. 2013) (per curiam) (clarifying that, on a Rule 12(b)(2) motion, a district court may “consider[ ] materials outside the pleadings” such as “sworn declarations” so long as court’s ultimate inquiry remains “whether [plaintiff] ha[s], through its pleadings and affidavits, made a prima facie showing of personal jurisdiction notwithstanding any controverting presentation by [defendant]” (internal quotation marks and citation omitted)). to find a donor for Ms. Aloisio. (Id. ¶¶ 7, 11). ZKRD contacted Defendant, which, alongside its subsidiary Bayerische Stammzellbank GGMBH (“BSB”), located a near-perfect match. (Id. ¶¶ 11, 14). BSB subsequently collected and

sent the blood products to New York-Presbyterian Hospital/Weill Cornell Medical Center for transfusion. (Id. ¶ 14; Holler Decl. ¶¶ 6(p), 9). At all relevant times, Defendant was aware that the shipment was headed to New York for the benefit of Ms. Aloisio. (Compl. ¶ 16). BSB did not, in fact, ship the correct product to New York. Rather, because of a “labelling error,” Ms. Aloisio was infused with the “wrong” stem cells — those of an imperfect match — in January 2019. (Compl. ¶¶ 17, 25). As a result, Ms. Aloisio developed severe GVHD, and “suffered from worsening

fevers, vomiting, dizziness, pain, diarrhea, infections, pneumonia, and a long list of other symptoms,” rendering her “too ill to receive a second transplant from a suitable donor.” (Id. ¶¶ 26-27). After a year of suffering, Ms. Aloisio died in January 2020. (Id. ¶ 28). 2. Defendant AKB Defendant is a German stem cell donor network with an “expansive donor registry” based in Gauting, Germany. (Compl. ¶¶ 8, 56). It is a “non- profit foundation, … dependent on donations to operate,” with fewer than twenty-five employees and operations limited exclusively to Germany. (Holler

Decl. ¶¶ 4-5, 14, 36). When Defendant receives a request from ZKRD, it performs “confirmatory typing” on a potential donor in its database, which consists of “examining the donor’s tissue characteristics” and “ensur[ing] that the potential donor does not have infections[.]” (Id. ¶ 6(g)-(h)). Where Defendant finds a suitable donor in its database, it makes a request to BSB to secure stem cells from the donor. (Id. ¶ 6(l)). Defendant did not

“manufacture,” “distribute,” “possess, inspect, touch, observe, or label any stem cell donations for Ms. Aloisio[,]” nor does it provide such services for any patient. (Id. ¶¶ 5, 6(p)); but see Compl. ¶ 9 (“AKB/BS[B] was the company responsible for collecting, labelling and preparing the stem cells for transport to New York[.]”)). And Defendant only receives remuneration from ZKRD for its confirmatory typing services. (Holler Decl. ¶ 11; but see Compl. ¶ 13 (alleging “AKB/BSB received compensation in excess of €30,000” for the stem cells provided to Ms. Aloisio)).

Plaintiff alleges that Defendant “has organized several thousand transplantations,” including fifteen in New York between 2017 and 2023. (Compl. ¶ 8; id. ¶¶ 37-51 (listing shipments); but see Holler Decl. ¶ 12 (“AKB has never sent any donor stem cells to New York, much less ship donor stem cells to New York on many occasions from 2017 through 2023[.]”)). However, according to Defendant, it has “no control over where in the world the stem cell donations are requested or ultimately implanted if a match is found.” (Holler Decl. ¶ 6(j)).

3. Plaintiff Sues in New York State Court Plaintiff initially brought suit in New York State Supreme Court against AKB, BSB, and several other defendants. In November 2020, Plaintiff voluntarily dismissed AKB from the action. (Dkt. #13-2).4 BSB moved to dismiss the complaint against it for lack of personal jurisdiction, which motion the trial court denied in August 2021. See Aloisio v. N.Y.-Presbyterian/Weill

Cornell Med. Ctr., 166 N.Y.S.3d 519, 519 (1st Dep’t 2022) (summarizing lower court procedural history). The First Department reversed, finding that there was no jurisdiction over BSB under C.P.L.R. § 302(a)(1) or (3)(ii). Id.
