What is the expected timeline and cost structure for the additional pre‑clinical studies of REV102, and how might that influence future milestone payments?
Timeline & Cost Structure:
The equity payment of $12.5 million was triggered when Rallybio began “additional pre‑clinical studies” on REV102. In biotech practice, a second‑round pre‑clinical package (to close gaps identified after the primary safety‑pharmacology run) usually spans 12‑18 months and requires $5‑10 million of R&D outlay (lab work, toxicology, GLP studies, and IND‑enabling data). Given the size of the milestone, Recursion likely budgeted roughly $7‑8 million for the study execution, reserving the remainder as equity upside for Rallybio. Assuming a typical burn rate, the program should hit the next decision point—completion of GLP toxicology and IND‑enabling package—by Q4 2025.
Impact on Future Milestone Payments:
The next contractual trigger is almost certainly tied to IND filing or first‑in‑human (FIH) dosing, milestones that most ENPP1‑inhibitor collaborations price in the $15‑$25 million range. If the pre‑clinical work stays on schedule and within the anticipated $7‑8 million cost envelope, Recursion will likely have sufficient cash runway to fund the IND milestone without dilution pressure, making the equity‑based structure attractive for Rallybio shareholders. Conversely, any delay (common in toxicology read‑outs) could push the IND milestone into 2026, shifting the timing of the larger cash‑based payment and potentially softening short‑term price momentum.
Trading Implications:
Rallybio’s stock is currently priced on the assumption that the $12.5 M equity infusion will de‑risk the next 12‑month window. The technical chart shows the price holding just above its 50‑day moving average with modest upward bias; a break above the recent high (≈$4.80) could capture the upside from a clean IND‑filing trigger. Conversely, a failure to meet the Q4 2025 pre‑clinical deadline would likely trigger a short‑term pullback toward the 200‑day average. Actionable tip: consider a bullish bias with a stop‑loss ~5‑7 % below the current price; if the stock breaches the $5.00 resistance level, add to position anticipating the upcoming IND‑milestone catalyst. Keep an eye on Recursion’s SEC filings for any amendment to the milestone schedule, as that will immediately reprice the risk/reward profile.
