Item 7.01 Regulation FD Disclosure
As previously announced, Precision BioSciences, Inc. (the “Company”) will host an investor webcast on May 27, 2026 at 8:00 a.m., Eastern Time to discuss new biopsy and clinical data from the ongoing Phase 1 ELIMINATE-B trial in chronic hepatitis B. The presentation will include new clinical data along with late-breaker biopsy data featured at the European Association for the Study of the Liver (“EASL”) Congress 2026 on May 27, 2026, in Barcelona, Spain.
Participants may access the live webcast and accompanying presentation materials on the Company’s website under Events & Presentations: https://investor.precisionbiosciences.com/events-and-presentations.
Also on May 27, 2026, the Company issued a press release to announce new and late-breaking PBGENE-HBV clinical data from the ELIMINATE-B study at EASL. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
Pursuant to General Instruction B.2 of Current Report on Form 8-K, the information contained in, or incorporated into, this Item 7.01 (including the press release attached hereto as Exhibit 99.1) of this Current Report on Form 8-K is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, nor shall it be deemed to be incorporated by reference into any registration statement or other filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.
Item 8.01 Other Events
On May 27, 2026, the Company issued a press release to announce new and late-breaking PBGENE-HBV clinical data from the ELIMINATE-B study at EASL. Clinical highlights from the press release include:
•New biopsy data demonstrate that PBGENE-HBV directly eliminated cccDNA through its primary mechanism leading to a 1-log (10-fold) reduction in cccDNA-derived transcripts.
•In the <1% of cccDNA remaining, PBGENE-HBV indels permanently inactivated viral replication by knocking out polymerase function.
•pgRNA established as the biomarker to directly reflect cccDNA elimination by PBGENE-HBV.     
•New clinical data demonstrate that PGENE-HBV achieved pgRNA loss in 100% of patients (n=6) with detectable pgRNA at baseline. Complete loss of detectable blood pgRNA directly corresponded to undetectable pgRNA in post-treatment liver biopsy, further supporting pgRNA as the appropriate clinical biomarker for assessing PBGENE-HBV effect on cccDNA in the liver.
•PBGENE-HBV has a clear therapeutic window with a well-characterized and manageable safety profile across multiple dosing cohort. As of data cutoff, 38 doses have been administered across 16 patients in 5 cohorts for the safety analysis. No dose limiting toxicities were observed. The most common adverse events include infusion-related reactions consistent with lipid nanoparticle (“LNP”) effects, with onset and resolution within 24 hours of infusion. While transient, ≥ Grade 3 reversible ALT/AST lab abnormalities have been observed, they were asymptomatic with no elevated bilirubin, and no Hy’s law in any patient at any dose level. Grade 3 hypotension was observed during dose escalation, and one patient in the highest dose cohort (0.8 mg/kg) experienced two serious adverse events (“SAEs”) after the second LNP administration. One of the events was deemed treatment related and mechanistically related to hypotension. The patient is ambulatory, home, and stable. The etiology of hypotension following subsequent doses of LNP is now understood and simple measures such as slower infusion rate and increased steroid doses have been implemented. Up to 20% of the doses delivered in the ELIMINATE-B trial have now been administered under the mitigation protocol and no ≥ Grade 3 hypotension events or ≥ Grade 3 LNP-related ALT/AST lab abnormalities have been observed since the implementation.
