SAN DIEGO, March 31, 2025 (GLOBE NEWSWIRE) -- Connect Biopharma Holdings Limited (Nasdaq: CNTB) (“Connect Biopharma”, “Connect” or the “Company”), a clinical-stage biopharmaceutical company focused on transforming acute and chronic care in asthma and chronic obstructive pulmonary disease (COPD), today reported financial results for the year ended December 31, 2024, and provided a business update.

“2024 was a transformative year for Connect as we strengthened our leadership team, made significant progress in becoming more U.S.-centric, and unveiled a rapid clinical development strategy for rademikibart initially focused on the treatment of acute asthma and COPD exacerbations, an area where no biologic therapies have been approved. To date, rademikibart has demonstrated a differentiated clinical profile in Phase 2 clinical trials achieving rapid improvement in pulmonary function in less than 24 hours, which was sustained through 24 weeks, highlighting its potential in both acute and chronic care,” said Barry Quart, Pharm.D., CEO and Director of Connect Biopharma. “We are on track to initiate parallel Phase 2 trials of rademikibart as an adjunct to standard of care for the treatment of acute asthma and COPD exacerbations in the second quarter of 2025, with data expected in the second half of 2026. We believe rademikibart has the potential to fundamentally alter the treatment paradigm for millions of asthma and COPD patients who experience acute exacerbations every year.”

Recent Highlights

Clinical Program Highlights

• Parallel acute exacerbation trials of rademikibart as an adjunct to standard of care in asthma and COPD are on track to be initiated in the second quarter of 2025, with data expected in the second half of 2026.
  

Corporate Highlights

• The Company continued making progress in becoming more U.S.-centric, including by:
  
  
  • assembling an experienced U.S. management team with deep expertise in drug development and regulatory execution, including having collectively received U.S. Food and Drug Administration (FDA) marketing approval for 16 therapeutic products, and with deep expertise in business development, corporate strategy, finance and operations;

  • transferring the initial manufacturing process for rademikibart to a U.S.-based contract manufacturing organization; and
    
  • transitioning to a U.S.-based independent registered accounting firm and voluntarily electing to become a domestic filer with the U.S. Securities and Exchange Commission (SEC), beginning with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, and on an ongoing basis with the regular filing of Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
    

Financial Results for the Year Ended December 31, 2024

• Cash, cash equivalents and short-term investments were $93.7 million as of December 31, 2024. Based on its current operating plans, the Company expects that its cash, cash equivalents and short-term investments will be sufficient to fund operations into 2027.
  
• Revenue for the year ended December 31, 2024, totaled $26.0 million, which included revenue recognized for the upfront fee, development milestones and cost reimbursements in connection with the license agreement with Simcere Pharmaceutical Co., Ltd. There was no comparable activity for the year ended December 31, 2023.
  
• Research and Development expense for the year ended December 31, 2024, was $29.3 million, compared with $53.0 million for the same period in 2023, a decrease of $23.7 million. The decrease in Research and Development expense was primarily due to the completion in late 2023 of the rademikibart global Phase 2b program in patients with chronic asthma and the rademikibart China pivotal trials for patients with atopic dermatitis.
  
• General and Administrative expense for the year ended December 31, 2024, was $19.2 million, compared with $16.1 million for the same period in 2023, an increase of $3.1 million. The increase in General and Administrative expense was primarily due to costs associated with executive departures, including cash severance and non-cash, share-based compensation expense related to certain stock option modifications.
  
• Net loss was $15.6 million, or $0.28 per share, for the year ended December 31, 2024, compared with a net loss of $62.1 million, or $1.13 per share, for the same period in 2023.
  

About Connect Biopharma and Rademikibart

Connect Biopharma is a clinical-stage biopharmaceutical company dedicated to transforming care for asthma and COPD. Headquartered in San Diego, California, the Company is advancing rademikibart, a next-generation, potentially best-in-class anti-interleukin-4-receptor alpha (IL-4Rα) antibody. With an initial focus on acute exacerbations—an area with significant unmet need—rademikibart has the potential to also drive chronic utilization in asthma and COPD amongst the millions of asthma and COPD patients in the U.S. who experience acute exacerbations annually. In a Phase 2 trial for asthma, rademikibart demonstrated strong efficacy and safety, with clinically meaningful reductions in exacerbations and rapid, statistically significant improvements in forced expiratory volume in one second, observed within one week—and in most cases, within 24 hours via home spirometry.
