Major programs commonly referenced in investor communications include PTG‑300 (rusfertide), PTG‑200 and PN‑943. The descriptions below reflect program focus and typical clinical objectives; readers should consult company filings for the latest protocol details and status updates.
Lead candidate(s)
-
PTG‑300 (rusfertide): Indication — polycythemia vera (PV). PTG‑300 is a hepcidin mimetic peptide formulated for subcutaneous administration designed to reduce excessive red blood cell counts and address iron dysregulation common in PV. As of June 30, 2024, PTG‑300 had advanced through late‑stage clinical testing with results and regulatory interactions shaping the path toward potential registration, with data readouts and regulatory discussions disclosed in investor presentations and SEC filings.
-
PTG‑200: Indication — inflammatory bowel disease (IBD), including Crohn’s disease and/or ulcerative colitis. PTG‑200 is an orally delivered peptide designed to act locally in the gut to modulate immune cell trafficking or signaling. PTG‑200 progressed through Phase 1/2 clinical evaluation to characterize safety, target engagement and proof‑of‑concept efficacy in IBD populations.
-
PN‑943: Indication — gut‑restricted immunomodulation for IBD (program naming and sponsor references vary in disclosures). PN‑943 has been described in company materials as an oral peptide candidate intended to limit systemic exposure while exerting local effects in the gastrointestinal tract; it was under clinical evaluation in early‑ to mid‑stage trials as of mid‑2024.
Mechanism class and clinical objectives: All lead candidates are peptide‑based and primarily aim to demonstrate safety, target engagement, and clinical efficacy endpoints relevant to their respective indications (e.g., hematologic control metrics for PV; endoscopic and symptomatic endpoints for IBD). Clinical objectives typically include dose selection, responder rates, biomarker effects, and safety/tolerability profiles.
Preclinical and earlier‑stage programs
Protagonist also advances discovery‑stage and preclinical peptides targeting additional immune and inflammatory pathways. These earlier programs are intended to feed the clinical pipeline and present optionality for future licensing or internal development. Preclinical efforts often focus on optimizing oral bioavailability, tissue targeting and peptide stability.

Traders should use limit orders and review implied and historical volatility metrics if using derivatives or other structured instruments.
Financials and results
Clinical‑stage companies like Protagonist characteristically have limited or no product revenue and therefore show operating losses driven by R&D and SG&A (selling, general & administrative) expenses. Financial health is primarily gauged by cash on hand, burn rate, expected runway and access to capital markets or strategic partners.
Quarterly and annual reports
What to monitor in Protagonist’s quarterly (10‑Q) and annual (10‑K) reports:
- Cash, cash equivalents and marketable securities — these determine near‑term runway absent new financing or revenue.
- R&D expense trends — indicate pace of clinical activity across PTG‑300, PTG‑200 and other programs.
- SG&A trends — reflect corporate scale‑up or cost control measures.
- Net loss and operating cash burn — investors watch quarterly burn to estimate months of runway.
- Contract liabilities, collaboration revenue and milestone arrangements — any non‑dilutive funding sources.
