What changed, and when

On 19 Feb 2026, Candel disclosed a purchase and sale agreement with funds managed by RTW Investments, LP, where RTW would pay $100m only upon FDA approval of CAN-2409 (aglatimagene besadenovec) in intermediate- and high-risk localized prostate cancer, in exchange for tiered royalties on future U.S. net sales. (Securities and Exchange Commission)
The disclosed economics include a 4.67% royalty on annual U.S. net sales up to $1b, 1.33% above $1b, a possible “ratchet” to 6.67% if sales miss specified levels (with cure provisions), and royalty payments ending once RTW has received $250m. (Securities and Exchange Commission)

60-second thesis frame

This is a launch-aligned, non-dilutive backstop that only activates on FDA approval, which can strengthen commercialization readiness but does not de-risk the regulatory outcome and introduces a capped, potentially ratcheting royalty overhang that can be expensive if uptake is slow. (Securities and Exchange Commission)
The core diligence hinge remains whether the Phase 3 dataset (PrTK03, NCT01436968) supporting a planned BLA is compelling enough for approval and, separately, whether urology and radiation oncology workflows plus payer dynamics will translate DFS benefit into rapid adoption at acceptable net pricing. (OncLive)
Candel’s 8-K also reported preliminary cash and cash equivalents of about $119.7m as of 31 Dec 2025, and the company separately priced a roughly $100m public equity offering (18,348,624 shares at $5.45) announced the same day. (Securities and Exchange Commission)

The seven diligence questions

Clinical

• Does the PrTK03 DFS benefit look durable and clinically meaningful in absolute terms (event timing, curve separation, and sensitivity analyses), beyond the headline HR 0.7 and p=0.0155? (OncLive)
• How operationally “real” is the safety and administration story in community settings (intraprostatic injections plus valacyclovir plus radiation, AE management, and any contraindications with ADT patterns)? (OncLive)

Payer or Access

• What is the value narrative payers will accept for localized disease treated with curative intent, given DFS is the primary endpoint (budget impact vs salvage treatments, metastasis prevention claims, and comparator choice)? (OncLive)
• What is the concrete reimbursement plan (site of care, coding strategy, gross-to-net assumptions), and how sensitive are RTW royalties to net price erosion given royalties are on “net sales” as defined in the agreement? (Securities and Exchange Commission)

Ops or Adoption

• Who “owns” administration in practice (urology vs radiation oncology), what training and throughput constraints exist, and what does the launch sequence look like for centers that already run EBRT pathways? (Urology Times)

Competitive

• How does CAN-2409 fit alongside intensification trends in intermediate/high-risk localized prostate cancer (radiation modality shifts, ADT use, emerging systemic add-ons), and what is the planned label positioning to avoid being squeezed into a narrow niche? (OncLive)

Team or Cap table

• Post-offering and with the Trinity term loan facility in place, what does the capital stack imply about time-to-launch runway and negotiating leverage, and how might the RTW “buy-out option” behave in a change-of-control scenario? (Securities and Exchange Commission)

Red flags

• Regulatory mismatch: FDA does not accept the totality of evidence for the intended label, or requires additional studies despite the SPA framing discussed publicly. (GlobeNewswire)
• Commercial traction miss: early uptake is slow (workflow friction, referral dynamics), triggering the higher royalty “ratchet” and compressing unit economics during the most cash-intensive launch window. (Securities and Exchange Commission)
• Net price compression: payer controls or required rebates drive low net sales, extending time to the $250m royalty cap while limiting funds available for broader pipeline investment. (Securities and Exchange Commission)

Next catalyst

Near-term: closing of the priced public offering, expected on or about 23 Feb 2026 (customary closing conditions). (Investing.com)
Strategic: BLA submission timing, with management guiding to Q4 2026. (GlobeNewswire)

FAQ

• What exactly changed by Candel Therapeutics’ “$100M Royalty Funding Agreement with RTW” news on 19 Feb 2026, and why does it matter for launch planning?
  RTW agreed to pay $100m only upon FDA approval of CAN-2409 for intermediate- and high-risk localized prostate cancer, giving Candel committed launch capital that does not dilute shareholders at signing. (Securities and Exchange Commission)
  In exchange, RTW receives a tiered royalty on U.S. net sales until it has received $250m in royalty payments, which affects future product-level economics. (Securities and Exchange Commission)
• What are the royalty economics in the 19 Feb 2026 RTW agreement with Candel Therapeutics, and what is the “ratchet”?
  The disclosed tiers are 4.67% of annual U.S. net sales up to $1b and 1.33% above $1b. (Securities and Exchange Commission)
  If annual net sales do not hit specified levels, the 4.67% tier can increase to 6.67%, subject to cure opportunities, and royalties end once RTW has received $250m. (Securities and Exchange Commission)
• What clinical evidence was cited alongside the 19 Feb 2026 RTW announcement for CAN-2409 in localized prostate cancer?
  Independent clinical reporting on PrTK03 (NCT01436968) describes statistically significant DFS improvement with CAN-2409 plus valacyclovir plus EBRT versus control, including HR 0.7 (p=0.0155) and supportive secondary measures such as pCR and prostate cancer–free survival. (OncLive)
  Candel has framed the Phase 3 program as conducted under an SPA with FDA, which, if aligned with the eventual BLA content, can support the approval package. (GlobeNewswire)
• What is the smaller localized prostate cancer program (ULYSSES) that often comes up in discussions after the 19 Feb 2026 RTW news?
  ULYSSES is a randomized trial of CAN-2409 during active surveillance for localized prostate cancer, listed by NCI as closed to accrual, and describes 2:1 randomization with standard active surveillance evaluations in both arms. (Cancer.gov)
  This program is distinct from the intermediate/high-risk radiation-adjunct setting and informs how CAN-2409 may or may not expand into earlier-risk populations. (Cancer.gov)
• How does the 19 Feb 2026 RTW deal interact with Candel’s other financing moves announced around the same time?
  Candel’s 8-K included preliminary year-end cash disclosure and described the RTW agreement as contingent on FDA approval, while the company also priced a roughly $100m public equity offering, indicating a multi-source financing approach around launch readiness. (Securities and Exchange Commission)
  This mix can reduce single-source dependency, but it also raises execution risk across dilution, debt covenants, and royalty burden. (Securities and Exchange Commission)
