Riding the Wave of Obesity-Treatment Stocks — A $130B+ Opportunity
VKTX vs. PFSA vs. GPCR — Why PFSA Looks Like an Investor’s Dream
Executive Summary
The obesity-treatment landscape is being reshaped by GLP‑1 drugs and the push toward oral regimens, with adjacent enabling technologies poised to expand access and improve outcomes. Within this surge, three names occupy very different positions on the valuation ladder: Viking Therapeutics (VKTX), Profusa (PFSA), and Structure Therapeutics (GPCR). Our view: PFSA’s nano‑cap profile, enabling biosensor platform, and near‑term commercialization path create an asymmetric setup that can re‑rate sharply on execution—making it, in our view, an investor’s dream come true.
Market‑Cap Snapshot (as of mid‑Aug 2025)
• Viking Therapeutics (VKTX): ~$4.5B market cap; widely held and highly sensitive to sector dataflow.
• Structure Therapeutics (GPCR): ~$1.1B–$1.2B market cap; pure‑play on oral GLP‑1 development.
• Profusa (PFSA): ~$20M market cap; nano‑cap with near‑term medtech commercialization and data/AI leverage.
Takeaway: PFSA’s valuation is orders of magnitude smaller than VKTX and GPCR, setting the stage for outsized percentage moves if the company executes on launch and clinical‑adjacent use cases.
Macro Context
The addressable market is expanding rapidly: aging populations, broadening payer coverage for weight‑loss therapies, and policy tailwinds supporting digital health and remote monitoring. The closely linked diabetes market strengthens the case for platforms that deliver continuous, clinical‑grade data.
Company Rundown
Viking Therapeutics (NASDAQ: VKTX) — Late‑Stage Momentum
Viking is advancing VK2735 (dual GLP‑1/GIP) across oral and subcutaneous formulations, aiming squarely at category leaders. With multiple mid‑to‑late‑stage milestones and high institutional awareness, VKTX remains a catalyst‑driven story. Valuation already embeds substantial expectations; upside hinges on clean data and partnering or M&A dynamics.
Structure Therapeutics (NASDAQ: GPCR) — Pure‑Play Oral GLP‑1
Structure’s aleniglipron (GSBR‑1290) targets the growing demand for needle‑free regimens. Multiple Phase 2 studies read into late 2025. As a $1B‑plus small cap, GPCR offers leverage to the oral GLP‑1 theme but remains capital‑intensive and competitive.
Profusa (NASDAQ: PFSA) — The Enabler: Continuous Biosensing + Data
PFSA’s platform centers on tissue‑integrated biosensors that deliver continuous, clinical‑grade signals (oxygen today; glucose in development). That matters for obesity and diabetes: continuous data can improve trial safety, adherence, and real‑world care—and underpins a higher‑margin software/data layer. With EU launch preparations for its CE‑marked oxygen product and a U.S. pivotal timeline on deck, PFSA’s path to revenue is measured in quarters, not decades.
Capital approach: Management emphasizes creative financing designed to help guard against dilution while advancing milestones—a constructive mix when paired with visible insider alignment.
Why PFSA Stands Out Now
1) Asymmetric Setup: Starting from a nano‑cap base (~$20M), modest execution on EU launch, U.S. pivotal progress, or data‑platform monetization can drive meaningful re‑rating.
2) Picks‑and‑Shovels Advantage: Instead of competing with big‑pharma GLP‑1s, PFSA enables the era—supporting trials, chronic‑care workflows, and remote management.
