Roches Columvi at a Crossroads: FDA Advisory Vote Sparks Questions on Market Dominance in Relapsed DLBCL

The recent FDA Oncology Drugs Advisory Committee (ODAC) meeting on May 20, 2025, delivered a pivotal verdict for Roche’s Columvi (glofitamab) combination therapy in relapsed/refractory diffuse large B-cell lymphoma (DLBCL). The 8-to-1 vote against the applicability of trial data to U.S. patients has thrown into question the drug’s path to full approval, with profound implications for Roche’s oncology portfolio and its market exclusivity in a crowded DLBCL treatment landscape.

The STARGLO Trial: A Tale of Geographic Disparity

The phase 3 STARGLO trial, which sought to confirm Columvi’s efficacy for DLBCL patients ineligible for autologous stem cell transplant (ASCT), enrolled 274 patients globally. However, only 25 (9%) hailed from North America—a glaring imbalance that fueled ODAC’s skepticism. While the global data showed a median overall survival (OS) benefit of 25.5 months versus 12.9 months for the control arm, regional outcomes diverged starkly:

• Asia-Pacific patients saw an OS hazard ratio (HR) of 0.41, with robust progression-free survival (PFS) gains.
• North American patients, by contrast, exhibited an HR of 2.62 for OS and 2.25 for PFS, hinting at worse outcomes.

The committee concluded that these disparities—driven by prognostic imbalances (e.g., more high-risk patients in the U.S. arm) and differing treatment practices—undermined the trial’s ability to demonstrate Columvi’s benefits for American patients.

Regulatory Crossroads: Approval or Rejection?

While the FDA is not bound by the ODAC’s recommendation, its vote signals a high hurdle for Roche. A denial would force the company to either:
1. Amend the sBLA to exclude U.S. patients from the trial’s primary endpoint analysis, risking narrower labeling.
2. Conduct a new trial focused on North American populations—a costly and time-consuming endeavor.

Either path would delay Columvi’s full approval, potentially ceding market share to competitors like polatuzumab vedotin (Polivy), which secured an ODAC green light just days earlier for first-line DLBCL.

Market Exclusivity Under Siege

Roche’s Columvi currently holds accelerated approval for relapsed/refractory DLBCL but faces mounting pressure from rivals. Polivy’s favorable ODAC vote, coupled with its broader indication for earlier-stage patients, positions it to dominate a $5 billion DLBCL market. Meanwhile, CAR-T therapies (e.g., Yescarta, Tecartus) loom as alternatives for eligible patients.

A Columvi denial could accelerate Roche’s decline in this space. Yet, the company’s deep oncology pipeline—including CD20/CD3 bispecifics and checkpoint inhibitors—offers a safety net. Investors must weigh short-term regulatory risks against long-term pipeline strength.

The Investment Play: Buying the Dip—or Walking Away?

The stock’s post-vote reaction (if any) will hinge on whether the FDA sides with ODAC. Key considerations for investors:
- Accelerated Approval Survival: Columvi’s current status may remain intact even if full approval is delayed, preserving near-term revenue.
- Geographic Market Opportunities: While U.S. access falters, Columvi’s global success (driven by Asia-Pacific) could fuel sales in other regions.
- Pipeline Momentum: Roche’s broader oncology pipeline, including its T-cell bispecifics, may offset DLBCL setbacks.

Actionable Takeaway: For contrarians, a Columvi setback could present a buying opportunity if Roche’s broader prospects remain robust. However, investors focused on DLBCL dominance may prefer Polivy’s clearer path to approval.

Conclusion: Navigating the Oncology Regulatory Minefield

The ODAC’s vote underscores a growing regulatory emphasis on trial data’s representativeness—a trend that could reshape drug development. For Roche, the path forward requires either rapid U.S.-focused data or a strategic pivot toward other indications. With DLBCL therapies now a high-stakes race, investors must decide whether to bet on Roche’s legacy oncology prowess or shift toward rising stars like Polivy. The stakes are high, but the rewards for those who read the regulatory tea leaves correctly could be immense.
