Tuesday Brief: Capital Gets Conditional
Monday’s session reinforced a “Capital Gets Conditional” regime: multi-year clinical durability (Sarepta) and clear regulatory differentiation (Guardant) are being rewarded, while payer execution and endpoint rigor are emerging as the binding constraints for 2026.
The market is telling a clear story. Three-year data that shows sustained separation from disease trajectory commands attention. Companion diagnostics that stay embedded in treatment-selection workflows protect reimbursement. And trial designs that defer on MRD rigor now face regulatory risk. Capital is available—but increasingly conditional on demonstrated execution.
The Morning Brief — What Matters Today
1. The Macro Anchor: UnitedHealth (UNH) Earnings
Timing: Pre-market this morning.
Why It Matters: UNH sets the baseline for 2026 medical cost trend and utilization assumptions. Consensus expects $2.09 EPS on $113.6 billion revenue. The medical cost ratio (MCR) has risen from 82% in 2022 to 89.9% in Q3 2025—today’s framing will determine whether the market treats this as cyclical or structural.
Watch For: Any indication that utilization pressure is structural rather than seasonal. If confirmed, expect immediate spillover implications for providers, services, and hospital IT budgets. Former CEO Stephen Hemsley returned in May 2025 and purchased $25 million in stock; Berkshire Hathaway disclosed a $1.57 billion investment. Long-term value investors see opportunity—today’s commentary will test that thesis.
2. Policy Moves From Theory to Execution
Deadline: February 1 (Sunday).
The Risk: UnitedHealthcare’s anatomical modifier enforcement is no longer a “policy note”—it is an execution risk. For surgical codes (CPT 10000-60000) and radiology codes (70000 series), claims must include proper laterality modifiers (LT, RT, 50) and digit-specific modifiers (FA, F1-F9, TA, T1-T9). Non-compliant submissions face edits or denials. Revenue cycle readiness will be tested next week, with near-term denial noise likely for unprepared labs and provider groups.
3. Deal Structure Still Governs the Tape
Context: The contrast between GSK–RAPT ($2.2B cash for de-risked Phase IIb asset) and BMS–Janux ($50M upfront, $800M milestones for platform) continues to define Q1 negotiation leverage. Monday’s Mirum–Bluejay close reinforced the pattern: Mirum paid $250M cash plus $370M stock for brelovitug, a Phase 3 asset with Breakthrough Therapy designation. Capital flows to de-risked assets with clear registrational paths.
Monday’s Material Moves
Clinical Signal: Durability as Currency (Sarepta)
What Happened: Sarepta released positive three-year EMBARK durability data for Elevidys in Duchenne muscular dystrophy, showing sustained motor-function benefit versus external controls. SRPT shares climbed approximately 6% on the news.
The data showed statistically significant benefits across all key functional measures. Patients receiving Elevidys saw a 73% reduction in the rate of decline on time-to-rise and a 70% reduction in the 10-meter walk/run measurement compared to external controls. These benefits not only persist but continue to strengthen over time, creating sustained and growing separation from expected disease trajectory. Of 64 patients treated in Part 1 of EMBARK, 52 continue to be followed in the EXPEDITION long-term study three years after treatment.
Why It Matters: After the safety scrutiny of 2025—including a patient death from acute liver injury in March that led to an FDA pause on dosing for non-ambulatory patients—durability is the gating variable. Multi-year data meaningfully resets the benefit-risk debate and strengthens the competitive moat around the franchise. No new treatment-related safety signals were observed. Sarepta plans rapamycin combination data by year-end that could support resumption of Elevidys in non-ambulatory patients, who represent half the DMD population.
EMBARK Three-Year Data
Design: Global, randomized, placebo-controlled Phase 3 | Population: Ambulatory DMD patients ages 4-7 at treatment | N: 64 treated, 52 in long-term follow-up | Key Results: 73% reduction in time-to-rise decline, 70% reduction in 10m walk/run decline vs. external controls | Safety: No new signals; 4 adverse events in Year 3, none novel
Regulatory Win: Diagnostic Workflows (Guardant)
What Happened: FDA approved Guardant360 CDx as a companion diagnostic to identify patients with BRAF V600E-mutant metastatic colorectal cancer (mCRC) who may benefit from treatment with Pfizer’s Braftovi (encorafenib) in combination with cetuximab and chemotherapy. The approval was supported by data from Pfizer’s Phase 3 BREAKWATER trial.
Why It Matters: This keeps liquid biopsy embedded in treatment-selection workflows, where reimbursement and guideline inclusion tend to follow labeled use. The clearance marks Guardant360 CDx’s 25th companion diagnostic indication across multiple tumor types and builds on coverage by Medicare and commercial payers representing more than 300 million covered lives. BRAF V600E mutations are present in approximately 8-10% of mCRC cases and represent an aggressive subtype with poor prognosis—early identification is critical for guiding patients to targeted therapies.
Pipeline Momentum: Regulatory Velocity Signals
Scancell: FDA cleared the IND application for a registrational Phase 3 trial of iSCIB1+ in advanced melanoma, with progression-free survival as the agreed surrogate endpoint. Phase 2 SCOPE data showed a 74% PFS rate at 16 months compared to 50% at 11.5 months for checkpoint inhibitor standard of care—a 24-percentage-point improvement. The company plans to initiate the Phase 3 trial in late 2026.
Innovent: FDA granted Fast Track designation for IBI3003, a GPRC5D/BCMA/CD3 trispecific antibody for relapsed or refractory multiple myeloma in patients who have received four or more prior therapies. The dual-targeting design aims to mitigate tumor escape associated with single-antigen targeting. A Phase 1/2 trial received U.S. IND approval in December 2025.
Why These Matter: These markers tighten timelines. They do not de-risk outcomes, but they change competitive sequencing and capital planning. IND clearances and Fast Track designations signal regulatory alignment that can compress development timelines by months.
Corporate Focus: Rare Disease Consolidation (Mirum)
What Happened: Mirum completed its acquisition of Bluejay Therapeutics, adding worldwide rights to brelovitug, a late-stage monoclonal antibody for chronic hepatitis delta virus (HDV). The transaction included $250M cash and $370M in Mirum stock, with up to $200M in additional milestone payments. Mirum also closed $268.5M in concurrent private placements.
Why It Matters: This is operational leverage in action. Brelovitug has FDA Breakthrough Therapy and EMA PRIME designations, with Phase 3 AZURE data expected in H2 2026. HDV has no FDA-approved therapies in the United States. Assets consolidate into teams with existing rare-disease commercial infrastructure—Mirum’s liver expertise from LIVMARLI and volixibat—improving execution odds even ahead of new data.
Policy & Regulatory Context
Myeloma Endpoints: The Shift to MRD
FDA draft guidance released January 20, 2026 reinforces a stricter stance on accelerated approvals in multiple myeloma. The guidance, titled “Minimal Residual Disease and Complete Response in Multiple Myeloma: Use as Endpoints to Support Accelerated Approval,” provides specific recommendations for sponsors designing trials using MRD or complete response as primary endpoints.
Implication: Minimal Residual Disease (MRD) negativity and Complete Response are moving from “exploratory” to “required” for accelerated approval pathways. The guidance follows the April 2024 Oncology Drug Advisory Committee meeting, where members unanimously agreed that MRD is acceptable as an endpoint for accelerated approval based on pooled analyses showing correlation with progression-free and overall survival.
Trial designs that defer MRD rigor now face regulatory risk. For myeloma developers, the message is clear: MRD assessment at 10⁻⁵ sensitivity or better is becoming the standard expectation, not an optional exploratory endpoint. Comments on the draft guidance are due by March 23, 2026.
The Day Ahead
- Tuesday, January 27: UnitedHealth Group (UNH) Earnings — Pre-market. Focus: Utilization trends, medical cost ratio framing, and 2026 guidance. The baseline for managed care assumptions this year.
- Friday, January 30: Regeneron (REGN) Earnings — Pre-market. Focus: EYLEA HD conversion metrics (Q4 US sales ~$1.1B combined with legacy EYLEA, HD up 66% YoY), franchise transition dynamics, and pipeline prioritization across ~40 investigational candidates. R&D guidance ($6B projected for 2026) will signal capital allocation priorities.
Capital Gets Conditional
Monday’s tape confirmed the 2026 framework. Sarepta’s three-year data demonstrates that durability is now currency—multi-year evidence of sustained benefit resets competitive moats and justifies premium valuations. Guardant’s CDx expansion shows that diagnostic workflows matter as much as detection novelty; staying embedded in treatment-selection pathways protects reimbursement.
The FDA’s MRD guidance signals tightening endpoint expectations. The February 1 payer deadline tests operational readiness. And the Mirum close reinforces that capital flows to de-risked assets with clear registrational paths and existing commercial infrastructure.
Capital is available. But it’s increasingly conditional on demonstrated execution—not just pipeline promise.

Frequently Asked Questions
What did Sarepta’s three-year Elevidys data show?
The EMBARK three-year data showed Elevidys-treated DMD patients had a 73% reduction in time-to-rise decline and 70% reduction in 10-meter walk/run decline compared to external controls. Benefits were statistically significant and continued to strengthen over time, with no new safety signals observed. Of 64 patients treated, 52 remain in long-term follow-up.
What is UnitedHealth’s medical cost ratio trend?
UnitedHealth’s medical cost ratio (MCR) has risen from 82% in 2022 to 89.9% in Q3 2025. Today’s earnings will determine whether the market views this trend as cyclical or structural, with implications for the entire managed care sector and healthcare services companies.
What are UnitedHealthcare’s February 1st modifier requirements?
Effective February 1, 2026, UnitedHealthcare requires proper anatomical and laterality modifiers for surgical codes (CPT 10000-60000) and radiology codes (70000 series). Claims must include laterality modifiers (LT, RT, 50) and digit-specific modifiers (FA, F1-F9, TA, T1-T9) where applicable. Non-compliant claims will face edits or denials.
What is the FDA’s new MRD guidance for myeloma?
The January 20, 2026 draft guidance establishes MRD negativity and complete response as acceptable primary endpoints for accelerated approval in multiple myeloma. MRD must be assessed at 10⁻⁵ sensitivity or better using flow cytometry or next-generation sequencing in patients who have achieved complete response. Comments are due March 23, 2026.
What is Guardant360 CDx now approved for in colorectal cancer?
Guardant360 CDx is now approved as a companion diagnostic to identify patients with BRAF V600E-mutant metastatic colorectal cancer who may benefit from Pfizer’s Braftovi (encorafenib) plus cetuximab and chemotherapy. This is the 25th CDx indication for Guardant360, with coverage representing over 300 million lives.
What did Mirum acquire from Bluejay Therapeutics?
Mirum acquired worldwide rights to brelovitug, a late-stage monoclonal antibody for chronic hepatitis delta virus (HDV) with FDA Breakthrough Therapy and EMA PRIME designations. The deal included $250M cash, $370M in stock, and up to $200M in milestones. Phase 3 data are expected H2 2026 with potential BLA submission in 2027.
What is Scancell’s iSCIB1+ and what did the IND clearance enable?
iSCIB1+ is a DNA immunotherapy for advanced melanoma that showed 74% progression-free survival at 16 months versus 50% for checkpoint inhibitor standard of care in Phase 2. The FDA IND clearance enables a registrational Phase 3 trial planned for late 2026 using PFS as the surrogate endpoint.
What is Innovent’s IBI3003?
IBI3003 is a trispecific antibody targeting GPRC5D, BCMA, and CD3 for relapsed/refractory multiple myeloma. The dual-targeting design aims to mitigate tumor escape from single-antigen therapies. It received FDA Fast Track designation for patients with 4+ prior therapies and U.S. IND approval in December 2025.
Why does durability data matter for gene therapy valuations?
Gene therapies are priced on the promise of “one-and-done” benefit. Multi-year durability data—like Sarepta’s 3-year EMBARK results—validates this thesis by showing sustained separation from disease trajectory. Without durability evidence, the benefit-risk calculus and premium pricing are harder to justify, especially after safety concerns.
What is the “Capital Gets Conditional” framework?
The 2026 dealmaking environment rewards demonstrated execution over pipeline promise. De-risked assets with clear registrational paths command acquisitions (GSK-RAPT, Mirum-Bluejay), while earlier platforms receive milestone-heavy structures (BMS-Janux). Companies lacking clinical clarity or operational infrastructure face capital constraints.
When is Regeneron reporting earnings and what should investors watch?
Regeneron reports Q4 2025 earnings Friday, January 30 before market open. Key focus areas: EYLEA HD conversion metrics (Q4 US sales ~$1.1B combined, HD up 66% YoY), franchise transition amid biosimilar settlements delaying launches until Q4 2026, and R&D investment guidance (~$6B projected for 2026) across ~40 investigational candidates.
What is hepatitis delta virus (HDV) and why is it significant?
HDV is the most severe form of viral hepatitis, occurring in people already infected with hepatitis B. Nearly half of those affected progress to liver-related death within 10 years. There are currently no FDA-approved therapies in the United States, making Mirum’s acquisition of brelovitug strategically significant.
