Other Events

On September 22, 2021, Puma Biotechnology, Inc. (the “Company”) and Wyeth LLC (“Wyeth”), as co-plaintiffs, filed suit against AstraZeneca Pharmaceuticals, LP, AstraZeneca AB (together “AstraZeneca”), and AstraZeneca PLC for infringement of United States Patent Nos. 10,603,314 (“the '314 patent”) and 10,596,162 (“the '162 patent”) (Puma Biotechnology, Inc. et al. v. AstraZeneca Pharmaceuticals LP et al., 1:21CV01338 (D. Del. Sep. 22, 2021) (the “AstraZeneca Litigation”)). The Company’s complaint alleges that AstraZeneca’s commercial manufacture, use, offer for sale, sale, distribution, and/or importation of Tagrisso® (osimertinib) products for the treatment of gefitinib and/or erlotinib-resistant non-small cell lung cancer infringes the '314 and '162 patents. The Company is an exclusive licensee of the '314 and '162 patents under the Pfizer Agreement. Plaintiffs seek a judgment that AstraZeneca’s product infringes the asserted patents and an award of monetary damages in an amount to be proven at trial. AstraZeneca filed an answer and counterclaims on November 5, 2021, including claims challenging the asserted patents as not infringed and/or invalid, and accusing plaintiffs of unclean hands and patent misuse.

On March 18, 2024, the court denied AstraZeneca’s motion for invalidity, denied AstraZeneca’s motion for summary judgment of non-infringement, except as to pre-issuance damages, and denied AstraZeneca’s motion for summary judgment on its advice of counsel defense. The court denied the plaintiffs’ and defendants’ motion to exclude certain expert testimony. AstraZeneca also moved to dismiss both the Company and Wyeth as plaintiffs for lack of constitutional standing. The court denied the motion to dismiss with respect to Wyeth and granted the motion with respect to the Company. The Company was dismissed as a plaintiff in the matter by order dated March 18, 2024. AstraZeneca subsequently moved to dismiss its counterclaims against the Company. On April 29, 2024, the Court granted the motion, removing the Company from the case. Wyeth remains in the case as a plaintiff and counterclaim-defendant, however. Under Puma’s worldwide exclusive license agreement with Pfizer, Inc. (the parent of Wyeth) as amended, the Company maintains contractual rights to recover monetary damages in the AstraZeneca litigation, and those contractual rights are unaffected by either the court’s March 18, 2024 order on the standing motion or its April 29, 2024 order dismissing AstraZeneca’s counterclaims against the Company.

A jury trial was held in the AstraZeneca Litigation beginning May 13, 2024. On May 17, 2024, a jury verdict was entered in favor of Wyeth, and against AstraZeneca. The jury found the '314 and '162 patents to be infringed by AstraZeneca and not invalid, and awarded Plaintiffs $107.5 million in damages for past acts of infringement. Further proceedings in the case will be scheduled before the Court to determine the appropriate royalty rate to be applied through the remainder of the term of the patents.

The Court has scheduled a bench trial for June 17-18 and 20, 2024 on AstraZeneca’s remaining equitable defenses of unclean hands, patent misuse, and indefiniteness.
