- Successful Completion of Phase 1 Study for Lead Oral Peptide Drug Candidate, PTG-100
- On Track to Initiate Phase 2b Study of PTG-100 in Moderate-to-Severe Ulcerative Colitis Patients by Year-End 2016

MILPITAS, Calif., Nov. 14, 2016 /PRNewswire/ -- Protagonist Therapeutics, Inc. (NASDAQ: PTGX) today reported its financial results for the quarter ended September 30, 2016 and provided an update on the company's recent achievements.

"Protagonist has accomplished several important milestones since the start of 2016, including reporting encouraging results from the Phase 1 clinical trial of PTG-100 and the successful completion of our initial public offering," said Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. "The IPO has provided us with the financial resources needed to rapidly advance the development of our pipeline of innovative peptide therapeutics."

"We anticipate commencing a Phase 2b trial for PTG-100 in ulcerative colitis by year-end 2016 and reporting full results by mid-2018.  We are also planning to advance two additional peptide drug candidates into Phase 1 clinical testing in 2017. These include PTG-200, our oral IL-23 receptor antagonist for the treatment of Crohn's disease, and PTG-300, an injectable Hepcidin mimetic, for iron overload disorders," Dr. Patel concluded.

Recent Achievements

  • Completed IPO, upsizing from initial target of $70 million to $90 million, with total gross proceeds of $93 million including partial exercise of underwriters' option to purchase additional shares. The company raised $83.6 million, net of underwriting discounts, commissions and offering costs, from the sale of 7.8 million shares of common stock.
  • Successfully completed a Phase 1 clinical trial of PTG-100, the company's oral peptide alpha-4-beta-7 antagonist, in healthy volunteers in Australia. Clinical data from this study was presented at United European Gastroenterology Week, on October 17 in Vienna, Austria.
  • Received SBIR funding for development of injectable hepcidin mimetics for treatment of iron overload disorders.
  • Strengthened board of directors with appointment of William D. Waddill, Calithera Chief Financial Officer.
  • U.S. Investigational New Drug (IND) application submitted to support Phase 2 development of PTG-100 in ulcerative colitis is now active.

Third Quarter 2016 Financial Results

Research and development expenses were $5.6 million for the third quarter of 2016, compared to approximately $3.2 million for the same period of 2015, an increase of $2.4 million. The increase was primarily due to increased expenses for contract consultants, contract manufacturing and other activities for PTG-100 clinical trials and other product candidate studies, as well as increases in salaries and employee related expenses.

General and administrative expenses were $1.6 million for the third quarter of 2016 compared to $0.9 million for the same period in 2015, an increase of $0.7 million. The increase was primarily due to increased salaries and employee-related expenses and increases in professional fees.

Net loss for the quarter ended September 30, 2016 was $7.1 million or $0.87 per common share, compared to a net loss of $3.4 million or $12.79 per common share for the same period in 2015.  As of September 30, 2016, Protagonist had approximately $98.5 million of cash and cash equivalents, short-term investments and short-term restricted cash.

About Protagonist Therapeutics

Protagonist Therapeutics is a clinical-stage biopharmaceutical company with a proprietary technology platform focused on discovering and developing peptide-based new chemical entities to address significant unmet medical needs. Its primary focus is on developing first-in-class oral peptide drugs that specifically target biological pathways also targeted by currently marketed injectable antibody drugs. Compared to injectable antibody drugs, Protagonist's oral peptides offer targeted delivery to the gastrointestinal (GI) tissue compartment, potential for improved safety due to minimal exposure in the blood, improved convenience and compliance, and potentially an opportunity for earlier introduction of targeted therapy for inflammatory bowel disease (IBD). Protagonist's initial lead peptide product candidates, PTG-100 and PTG-200, are based on this approach, and the company believes they have the potential to transform the existing treatment paradigm for IBD, a GI disease consisting primarily of ulcerative colitis and Crohn's disease.

PTG-100, a potential first-in-class oral alpha-4-beta-7 integrin antagonist that is being developed initially for moderate-to-severe ulcerative colitis, has now completed a phase 1 clinical trial in normal healthy volunteers.  PTG-200, a potential first-in-class oral Interleukin-23 receptor antagonist is being developed initially for moderate-to-severe Crohn's disease and is currently in IND-enabling studies.

The company has a peptide technology platform that enables the discovery of oral and injectable peptides that can be utilized against a diverse set of targets and diseases including, but not confined to the GI. In addition to PTG-100 and PTG-200, the company is engaged in the discovery and development of injectable hepcidin mimetics, including one lead compound from this program, PTG-300, which is currently in pre-clinical development. These mimetics have potential utility for the treatment of iron overload disorders, such as transfusion dependent beta-thalassemia and hereditary hemochromatosis (HH), each of which may qualify PTG-300 for orphan drug designation.  

Protagonist is headquartered in Milpitas, California with its pre-clinical and clinical staff in California, and discovery operations both in California and in Brisbane, Queensland, Australia. For further information, please visit
