"We are excited to expand our neuroscience portfolio as we welcome Karuna to Bristol Myers Squibb," said Chris Boerner, Ph.D., Chief Executive Officer, Bristol Myers Squibb. "Importantly, this transaction aligns with our commitment to strengthening BMS’s growth profile in the latter half of the decade and beyond. We look forward to working with Karuna’s talented team to bring KarXT to patients with schizophrenia later this year."

Through this transaction, BMS has added KarXT (xanomeline-trospium), an antipsychotic with a novel mechanism of action and a differentiated efficacy and safety profile, and Karuna’s early-stage and pre-clinical pipeline. KarXT has a Prescription Drug User Fee Act (PDUFA) date of September 26, 2024 for the treatment of schizophrenia in adults. KarXT is also in registrational trials both for adjunctive therapy to existing standard of care agents in schizophrenia and for the treatment of psychosis in patients with Alzheimer’s disease, with potential to expand to additional indications, including Bipolar I disorder and Alzheimer’s disease agitation.

As previously disclosed, the transaction is expected to be dilutive to Bristol Myers Squibb’s non-GAAP diluted earnings per share by approximately $0.30 in 2024 from the financing cost of the transaction, which is primarily from a recently completed new debt issuance. Bristol Myers Squibb expects to offset the operational expenses of the transaction through continued disciplined resource allocation, cost efficiencies and portfolio prioritization. Bristol Myers Squibb’s cash flows and strong financial profile enable continued commitment to strong investment-grade credit ratings and investment for growth through business development opportunities and distributions to shareholders through ongoing dividends and share repurchases.

The transaction will be accounted for as an asset acquisition resulting in an approximately $12 billion one-time, non-deductible Acquired In-Process Research and Development (Acquired IPR&D) charge impacting both 2024 first quarter and full-year GAAP and non-GAAP EPS by approximately $5.93.

Consistent with past practice, Bristol Myers Squibb generally provides updates to its financial outlook once each quarter. When considering Bristol Myers Squibb’s financial outlook issued on February 2, 2024, investors and analysts should take into account the impacts outlined above. Bristol Myers Squibb will provide an update to its financial outlook when it reports first quarter 2024 results on April 25, 2024.

"2023 was a transformational year for Alpine, with initial IgA nephropathy (IgAN) data presented at the American Society of Nephrology Kidney Week 2023 suggesting a best-in-class profile for povetacicept, our next-generation dual BAFF/APRIL inhibitor. With our encouraging data set in IgAN, convenient once monthly dosing regimen, and strong balance sheet, we are rapidly advancing development of povetacicept as a potentially meaningful new therapeutic option for patients living with IgAN, systemic lupus erythematosus (SLE), and multiple other autoantibody-related diseases," said Mitchell H. Gold, MD, Executive Chairman and Chief Executive Officer of Alpine.

Dr. Gold continued, "Looking ahead, Alpine is well positioned for a year of meaningful catalysts, with multiple updates for povetacicept in IgAN and other indications, and the planned initiation of RAINIER, a pivotal phase 3 study of povetacicept in IgAN, and DENALI, a phase 2 study of povetacicept in SLE. In addition to updates on our clinical studies, we look forward to sharing translational data that further supports the best-in-class potential of povetacicept in multiple inflammatory diseases."
Fourth Quarter 2023 Corporate Updates
Povetacicept (ALPN-303)
•First clinical data in IgAN demonstrate that povetacicept 80 mg administered once every four-weeks (Q4W) reduced proteinuria (as assessed by urine protein to creatinine ratio, UPCR) by greater than 50% and was associated with stable renal function (as assessed by estimated glomerular filtration rate, eGFR) at six months. In addition, povetacicept was well tolerated during subcutaneous administration, with no instances of IgG < 3 g/L, and no severe infections (2023 American Society of Nephrology Kidney Week).
•In a model of murine experimental autoimmune myasthenia gravis, povetacicept improved disease activity, with clinical scores superior to treatment with either the FcRn inhibitor efgartigimod or an anti-CD20 depleting antibody (2023 American Association of Neuromuscular & Electrodiagnostic Medicine Annual Meeting).
•New translational data from povetacicept in systemic lupus erythematosus demonstrate that povetacicept, as compared to single BAFF or APRIL pathway inhibitors, more potently downregulates genes associated with activation in B cells and significantly reduces multiple disease parameters in a mouse model of lupus, more effectively than WT TACI-Fc or conventional B cell depletion (2023 American College of Rheumatology Convergence).
•Throughout 2023, the Company presented multiple oral and poster presentations on povetacicept at scientific conferences.
Corporate Updates
•The Company plans to present additional data on povetacicept in IgA nephropathy, including follow up data from the 80 mg Q4W and initial data from the IgAN 240 mg Q4W dose cohorts, during a Late Breaking Abstract session at the World Congress of Nephrology 2024 on Monday, April 15th at 4:45 PM ET.
•The Company plans to present new preclinical data on povetacicept, demonstrating its greater distribution to disease-related end organs compared with WT TACI-Ig, at the 14th European Lupus Meeting. These findings correlate with povetacicept’s improved efficacy in multiple preclinical disease models.

•The Company intends to initiate RAINIER, a pivotal phase 3 study of povetacicept in IgA nephropathy and DENALI, a phase 2 study of povetacicept in systemic lupus erythematosus in the second half of 2024, pending regulatory agreement.
•The Company plans to share initial data from RUBY-4 in autoimmune cytopenias in the first half of 2024 at a relevant scientific congress.
•The Company amended its option and license agreement on acazicolcept with AbbVie, stopping enrollment in the phase 2 study in systemic lupus erythematosus (Synergy), and facilitating early assessment of data.
•The Company ended the year with $368.2 million in cash and investments as of December 31, 2023, which the Company anticipates should be sufficient to fund its planned operations into 2026.
2023 Financial Results
Cash Position and Runway: As of December 31, 2023, Alpine’s cash and investments totaled $368.2 million compared to $273.4 million as of December 31, 2022. The Company anticipates its current cash and investments are sufficient to fund planned operations into 2026.
Collaboration Revenue: For the year ended December 31, 2023, collaboration revenue was $58.9 million compared to $30.1 million for the same period in 2022. The increase in collaboration revenue relates primarily to a $24.9 million increase in AbbVie revenue, of which $20.4 million relates to a cumulative catch-up adjustment resulting from the completion of enrollment in Synergy per the amendment with AbbVie, and a $4.5 million increase in Amgen revenue, driven primarily by the expiration of Amgen’s option to select a third Research Program. These increases were partially offset by a $0.6 million decrease in Adaptimmune revenue as we completed our final deliverables under the agreement in June 2023.
Research and Development Expense: For the year ended December 31, 2023, research and development expense, inclusive of non-cash expenses, were $80.9 million compared to $70.2 million for the same period in 2022. The increase of $10.7 million was driven by an $8.2 million increase in povetacicept costs, primarily related to higher clinical trial costs, process development, and manufacturing, a $1.3 million increase in acazicolcept costs, due primarily to process development and manufacturing costs, and a $7.7 million increase in personnel costs.
General and Administrative Expenses: For the year ended December 31, 2023, general and administrative expenses, inclusive of non-cash expenses, were $22.2 million compared to $18.0 million for the same period in 2022. The increase of $4.3 million was primarily attributable to increases in personnel costs and professional services.
Net Loss: Net loss for the year ended December 31, 2023, was $32.2 million compared to $57.8 million for the same period in 2022.
