SAN DIEGO, Aug. 28, 2026 (GLOBE NEWSWIRE) -- iBio, Inc. (NASDAQ: IBIO), a clinical-stage biotechnology company developing long-acting antibody therapeutics for obesity, cardiometabolic and cardiopulmonary diseases, today announced its financial results for the fiscal year ended June 30, 2026, and provided a corporate update on its progress.

“Fiscal year 2026 was a transformative year for iBio, most importantly marked by our transition to a clinical-stage company with the initiation of the Phase 1 clinical trial of IBIO-600, a potentially best-in-class, long-acting anti-myostatin monoclonal antibody designed to preserve muscle and improve body composition,” said Martin Brenner, Ph.D., DVM, Chief Executive Officer and Chief Scientific Officer of iBio. “Additional highlights came from our IBIO-610 program, where we presented preclinical data supporting its potential for fat-selective weight loss, complementing with current GLP-1 therapies by increasing fat loss while preserving lean mass, and to reduce weight regain following GLP-1 discontinuation. We are excited to build on this progress as we continue advancing our pipeline and working toward our mission of delivering transformative treatments to patients.”

Progress on Obesity and Cardiometabolic Pipeline

  • Advanced IBIO-610, iBio’s long-acting Activin E antibody, into IND-enabling studies. In obese non-human primates, a single dose produced near-complete suppression of active Activin E for up to eight weeks and demonstrated a prolonged pharmacokinetic profile supporting the potential for infrequent dosing. Additional preclinical studies in rodents demonstrated fat-selective weight loss, additive weight loss and enhanced body-composition effects in combination with semaglutide, and prevention of weight regain following GLP-1 discontinuation. These data support IBIO-610’s potential as a differentiated treatment for obesity and related cardiometabolic diseases.
  • Advanced IBIO-600, iBio’s long-acting myostatin antibody, through the single ascending dose portion of its first-in-human Phase 1 clinical trial, dosing 31 of the 32 planned participants across all four planned cohorts with no safety findings identified that precluded dose escalation. IBIO-600 is being developed to preserve muscle and improve body composition, including as a potential complement to GLP-1-based therapies. iBio is now preparing to advance IBIO-600 into the multiple ascending dose escalation portion of the clinical trial.
  • Advanced IBIO-800, iBio’s myostatin × Activin A bispecific antibody, into IND-enabling development following selection of a development candidate. iBio initiated CMC and IND-enabling nonclinical development and presented preclinical data supporting its potential to preserve and increase muscle and address cardiopulmonary disease, with an initial focus on pulmonary hypertension associated with heart failure with preserved ejection fraction (PH-HFpEF).
  • In-licensed all rights to AstralBio’s amylin receptor antibody program that includes a portfolio of next-generation antibody agonists designed to achieve differentiated receptor pharmacology. The program includes selective AMY1 and AMY3 receptor agonists, selective amylin receptor agonists targeting both AMY1 and AMY3, and dual amylin and calcitonin receptor agonists. Candidates are advancing through preclinical characterization to identify the pharmacologic profiles best suited to the treatment of obesity and metabolic disease.

Corporate Developments

Financing and Capital Resources

  • Closed a public offering in August 2025 for total potential gross proceeds of up to $100 million (assuming the exercise of all of the warrants sold in the offering in full for cash), led by Balyasny Asset Management with participation from Cormorant Asset Management, Adage Capital Partners, Ally Bridge Group, Marshall Wace, Coastlands Capital, SilverArc Capital Management, Vestal Point Capital, and Ausangate Capital.
  • Closed a $26 million private placement in January 2026 with healthcare-focused institutional investors led by Frazier Life Sciences, along with participation from other existing investors.
  • Entered into an Open Market Sale AgreementSM™ with Jefferies LLC providing for the sale, from time to time, of up to $100 million of shares of iBio common stock.

Leadership Updates

  • Strengthened the Board with the appointment of Elizabeth Stoner, M.D., who brings deep biotechnology industry experience and expertise in capital markets and clinical-stage drug development.
  • Appointed Molly Carr, M.D. as iBio’s Chief Medical Officer, bringing more than 30 years of clinical, academic and biopharmaceutical experience in endocrinology and metabolic diseases to lead iBio’s global clinical strategy, medical affairs and regulatory initiatives.

“In the last fiscal year, we paired significant scientific progress with disciplined financial execution, substantially strengthening iBio’s balance sheet as we advanced our pipeline into clinical development,” said Felipe Duran, Chief Financial Officer. “Our successful financings, which extended our cash runway into fiscal year 2028, together with the addition of highly experienced leaders to our Board and management team, provide a strong foundation to execute on our clinical programs and translate continued scientific progress into meaningful value for patients and shareholders.”

Financial Results:

Revenues for the fiscal year ended June 30, 2026, were approximately $0.1 million, a decrease of $0.3 million over the $0.4 million in revenue for the fiscal year 2025.

Research and Development (“R&D”) expenses for the fiscal year ended June 30, 2026, and June 30, 2025, were approximately $19.6 million and $8.3 million, respectively, an increase of approximately $11.3 million. The increase in R&D expenses is mainly due to increased spending of approximately $8.4 million on consultants and outside services supporting our R&D efforts, including NHP studies and CMC activities, for iBio’s IBIO-610 and IBIO-600 programs and other preclinical pipeline assets, and a $2.5 million development milestone.

General and Administrative expenses for the fiscal year ended June 30, 2026, and June 30, 2025, were approximately $10.6 million and $10.7 million, respectively, a decrease of approximately $0.1 million.

Impairment of Indefinite-Lived Intangible Assets for the fiscal year ended June 30, 2026, was approximately $5.0 million and was attributable to the impairment of our indefinite-lived intangible asset, IBIO-101. No impairments of indefinite-lived intangible assets were recorded for the fiscal year ended June 30, 2025.

iBio held cash and cash equivalents and investments in debt securities of approximately $88.0 million as of June 30, 2026.
