"Pieris continues to advance potentially transformative clinical and preclinical programs, while remaining committed to cost-effective operations. Our top priority is to obtain data from the elarekibep Phase 2a study in asthma. We are pleased that our partner and study sponsor, AstraZeneca, is significantly increasing operational resources to complete the trial. As an inhaled therapeutic, elarekibep offers the promise of a superior product profile compared to currently available injectable drugs and further validation of our broader respiratory franchise," said Stephen S. Yoder, President and CEO of Pieris. "Respiratory diseases such as asthma, IPF and chronic obstructive pulmonary disease are underserved by the biopharma industry despite high mortality rates, impaired quality of life, and a significant burden on the healthcare system. We believe Pieris is well positioned to develop differentiated inhaled biologics medicines that could fundamentally alter how respiratory diseases are managed.

"Alongside our lead program, elarekibep, Pieris is advancing additional clinical and preclinical programs that could result in meaningful new medicines. We are evaluating opportunities to support the long-term development of these promising therapeutic candidates."

Respiratory Pipeline:

Elarekibep and AstraZeneca Collaboration: Enrollment is ongoing in the multi-center, placebo-controlled Phase 2a study of dry powder inhaler-formulated elarekibep, an IL-4 receptor alpha (IL-4Rα) inhibitor being developed for the treatment of moderate-to-severe asthma. Topline results measuring placebo-adjusted FEV1 improvement at four weeks are now expected to be reported by the middle of 2024 based on AstraZeneca’s most recent projections. AstraZeneca has communicated to the Company that completion of the Phase 2a study remains an important priority and that additional resources have been provided to achieve study completion, including a commitment to adding several new countries and a significant number of additional clinical sites, bringing the total number to more than 100 sites.

Elarekibep is validated by dupilumab, an FDA-approved inhibitor of IL-4Rα, that has demonstrated reduced levels of fractional exhaled nitric oxide (FeNO) and clinical efficacy in uncontrolled, moderate-to-severe asthma. Furthermore, recently reported dupilumab Phase 3 study results have shown efficacy in chronic obstructive pulmonary disease (COPD). Previously reported elarekibep Phase 1 results demonstrated reduced FeNO levels in mild asthma patients, and a favorable safety profile.

Pieris retains co-development and U.S. co-commercialization rights for elarekibep, exercisable following completion of the ongoing Phase 2a study. Beyond elarekibep, Pieris continues to develop two preclinical programs with AstraZeneca for which it also retains co-development and U.S. co-commercialization options.
PRS-220: Pieris continues the development of an inhaled Anticalin protein targeting connective tissue growth factor (CTGF) for the treatment of IPF and other fibrotic lung diseases. In preclinical models, PRS-220 demonstrated superior on-target potency compared to pamrevlumab, an intravenously infused CTGF antagonist in late-stage clinical development. The Company believes that the inhaled route of administration allows for superior lung exposure. These attributes, combined with the convenience of at-home administration via inhalation, result in PRS-220 having best-in-class potential.

The Company is currently dosing healthy volunteers in a Phase 1 study of PRS-220 and expects to report results in the second half of this year. Pieris continues to benefit from a meaningful grant from the Bavarian government, which supports early-stage development of this program.
PRS-400: Pieris continues to advance PRS-400, an inhaled anti-Jagged-1 Anticalin therapeutic program with potential in a wide range of respiratory diseases driven by mucus hypersecretion. PRS-400 is designed to exert clinical activity by disrupting mucus-mediated pathology in the airways, while avoiding inhibition of healthy mucus production outside of the lungs. Previously presented preclinical data demonstrate that PRS-400 potently inhibits Jagged-1-induced Notch 2 signaling in relevant tissue in the lung. In patients with muco-obstructive respiratory diseases, such as those living with inadequately controlled COPD with chronic bronchitis, PRS-400 has potential to improve clinical outcomes and improve quality of life. PRS-400 is advancing toward development candidate nomination later this year.
Immuno-Oncology Pipeline:

Pieris’s immuno-oncology pipeline continues to progress in a cost-efficient manner with the benefit of its partners. The Company believes that multiple opportunities exist to generate value from this portfolio based on promising preclinical and clinical data.

PRS-344/S095012 and Servier Collaboration: Pieris and Servier continue to enroll the escalation portion of the Phase 1/2 study of PRS-344/S095012, a 4-1BB/PD-L1 bispecific MabcalinTM (antibody-Anticalin protein) compound for the treatment of solid tumors, for which Pieris holds full U.S. rights and will receive development milestones and royalties on ex-U.S. sales by Servier. Additionally, Servier discontinued development of PRS-352/S095025, an PD-L1/OX40 bispecific Mabcalin compound, for strategic reasons.
Seagen Collaboration: In January 2023, Seagen initiated a Phase 1 study for SGN-BB228 (also known as PRS-346), triggering a $5 million milestone payment to Pieris. SGN-BB228 is a first-in-class CD228/4-1BB bispecific antibody-Anticalin compound designed to provide a potent costimulatory bridge between tumor-specific T cells and CD228-expressing tumor cells. Pieris and Seagen continue to collaborate on two other undisclosed bispecific programs.
PRS-342/BOS-342: Boston Pharmaceuticals continues to advance PRS-342/BOS-342, a 4-1BB/GPC3 bispecific Mabcalin compound, toward the clinic, with Phase 1 expected to begin in the coming months.
Fiscal Year End Financial Update:

Cash Position – Cash, cash equivalents, and investments totaled $59.2 million for the year ended December 31, 2022, compared to a cash and cash equivalents balance of $117.8 million for the year ended December 31, 2021. The decrease was due to funding operations in 2022. The Company believes operations are sufficiently funded for more than the next 12 months.

R&D Expense – R&D expenses were $53.0 million for the year ended December 31, 2022, compared to $66.7 million for the year ended December 31, 2021. The decrease was due to lower overall program costs for both elarekibep and cinrebafusp alfa, lower manufacturing costs across other later-stage respiratory and immuno-oncology programs, lower license fees and lower consulting costs. These lower costs were partially offset by higher clinical costs for PRS-220 and PRS-344/S095012, higher pre-clinical costs for PRS-400, and an increase in personnel and travel costs.

G&A Expense – G&A expenses were $16.4 million for the year ended December 31, 2022, compared to $16.6 million for the year ended December 31, 2021. The period-over-period decrease was driven primarily by lower personnel, facilities and audit and tax costs, partially offset by higher business development, travel and amortization of deferred costs related to revenue recognition.

Other Income – For the year ended December 31, 2022, $8.2 million of grant income was recorded with respect to PRS-220, compared to $3.7 million for the year ended December 31, 2021. The increase was due to higher overall costs incurred on PRS-220 as the program progressed into a Phase 1 clinical study.

Net Loss – Net loss was $33.3 million or $(0.45) per share for the year ended December 31, 2022, compared to a net loss of $45.7 million or $(0.71) per share for the year ended December 31, 2021.
