Positive
  • Positive clinical data on povetacicept in IgAN and SLE
  • Plans for pivotal phase 3 trial in IgAN and phase 2 trial in SLE
  • Significant increase in collaboration revenue
  • Strong cash position to fund operations into 2026
Negative
  • None.

Alpine Immune Sciences' reported financials reflect a strategic focus on advancing their lead candidate povetacicept, with a robust cash position to support operations into 2026. The increase in collaboration revenue by almost 96%, largely attributed to the amended agreement with AbbVie, is a positive indicator of the company's ability to monetize its research partnerships effectively. However, the reported net loss decrease from $57.8 million in 2022 to $32.2 million in 2023, while still significant, suggests improved cost management and potential operational efficiencies. The research and development expenses have increased, indicating ongoing investment in their pipeline, which is necessary for long-term growth but could pressure short-term financial performance. Investors should note the company's commitment to R&D as a sign of confidence in its pipeline's potential.

The clinical progression of povetacicept, particularly in IgA nephropathy (IgAN), is noteworthy. The reduction in proteinuria and stable renal function at six months suggest a promising therapeutic profile. The advancement into a pivotal phase 3 trial is a critical milestone that could significantly impact the company's valuation if successful. Moreover, the expansion into systemic lupus erythematosus (SLE) with a planned phase 2 trial indicates a strategic move to widen the drug's potential market. The translational data supporting its efficacy in multiple inflammatory diseases further underpins its best-in-class potential. The medical community will be watching closely for the upcoming data presentations, as these will offer deeper insights into povetacicept's efficacy and safety profile.

Alpine Immune Sciences' strategic amendments with AbbVie and the planned initiation of new clinical trials are indicative of a proactive approach to pipeline development and market positioning. The biotech sector places a premium on such innovative treatments for autoimmune and inflammatory diseases, which currently have high unmet medical needs. The company's focus on a next-generation dual BAFF/APRIL inhibitor may set them apart in a competitive landscape. The current cash runway into 2026 provides the company with a buffer to navigate the costly clinical trial phases without immediate fundraising pressures. This financial stability, coupled with potential clinical milestones, could make Alpine an interesting case for investors tracking the immunotherapy space.

-- Clinical data on povetacicept in IgA nephropathy will be updated at the upcoming WCN meeting, including follow up at 80 mg and initial data at 240 mg SC once every four-weeks --

-- Povetacicept advancing towards a pivotal phase 3 trial in IgA nephropathy and a phase 2 trial in systemic lupus erythematosus --

SEATTLE--(BUSINESS WIRE)-- Alpine Immune Sciences, Inc. (NASDAQ: ALPN), a leading clinical-stage immunotherapy company focused on developing innovative treatments for autoimmune and inflammatory diseases, today reported full year 2023 financial results and company highlights for the fourth quarter ended December 31, 2023.

“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 (Full List of Company Publications and Presentations).

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.

About Povetacicept (ALPN-303)

Povetacicept (ALPN-303) is a dual antagonist of the BAFF (B cell activating factor) and APRIL (a proliferation inducing ligand) cytokines, which play key roles in pathogenesis of multiple autoimmune diseases via their roles in the activation, differentiation and/or survival of B cells, particularly antibody-secreting cells, as well as T cells and innate immune cells. Based upon an engineered TACI (transmembrane activator and CAML interactor) domain, povetacicept has exhibited greater potency in preclinical studies versus other inhibitors of BAFF and/or APRIL alone and B cell depletion. Povetacicept is in development for multiple autoimmune diseases, including IgA nephropathy and other autoimmune kidney diseases, systemic lupus erythematosus, and autoimmune cytopenias.
