AI OverviewAI overview is shown in English only.

Lyell Immunopharma, Inc. (LYEL) is a late-stage clinical company developing next-generation CAR T-cell therapies for hematologic malignancies and solid tumors, with a lead program in large B-cell lymphoma and an internal manufacturing facility.

  • Cash & equivalents of $73.0M as of 2026-06-30 [sec].
  • Total revenue of $0.0M and net income of -$44.8M as of 2026-06-30 [sec].
  • Lead program ronde-cel (CD19/CD20 dual-targeting CAR T) is in Phase 3 trials PiNACLE (3L+ setting) and PiNACLE-H2H (2L setting) [sec_mda · as of 2026-08-06].
  • Owns and operates the LyFE Manufacturing Center with expected capacity >1,200 CAR T-cell doses/year [sec_mda · as of 2026-08-06].
  • Acquired exclusive global license (ex-China) for LYL273, a GCC-targeted CAR T for solid tumors [sec_mda · as of 2026-08-06].

What works

  • Lead program ronde-cel has advanced to Phase 3 pivotal trials (PiNACLE and PiNACLE-H2H), indicating regulatory alignment and clinical progress [sec_mda · as of 2026-08-06].
  • Internal manufacturing facility (LyFE) is operational and expected to support both clinical and commercial supply with >1,200 doses/year capacity [sec_mda · as of 2026-08-06].
  • Dual-targeting CD19/CD20 approach may offer differentiation versus approved first-generation CD19 CAR T products [sec_mda · as of 2026-08-06].

What to weigh

  • No revenue generated to date; net loss of $44.8M in the latest quarter (as of 2026-06-30) [sec].
  • Cash position of $73.0M (as of 2026-06-30) may be limited relative to the capital required to complete multiple Phase 3 trials and potential BLA submission [sec].
  • Solid tumor program LYL273 is early-stage (Phase 1/2) and relies on clinical proof-of-concept from an investigator-sponsored trial in China [sec_mda · as of 2026-08-06].
  • PiNACLE-H2H is a head-to-head Phase 3 trial against approved CAR T therapies (axi-cel, liso-cel), which carries execution and competitive risk [sec_mda · as of 2026-08-06].

  • PiNACLE-H2H trial design

    “Patients are randomized to either ronde-cel or investigator's choice of axicabtagene ciloleucel (axi-cel) or lisocabtagene maraleucel (liso-cel).”

    SEC MD&A · August 6, 2026

  • LYL273 license and target

    “we acquired an exclusive global license for LYL273 (excluding mainland China, Hong Kong, Macau and Taiwan), a guanylyl cyclase C (GCC)-targeted CAR T-cell product candidate”

Catalyst timeline

  • 2022-08-01 · Phase 2 start for LYL273 in metastatic colorectal cancer — A Phase 1/2 study evaluating LYL273 in patients with relapsed/refractory metastatic colorectal cancer.
  • 2023-05-09 · Phase 2 start for ronde-cel in aggressive B-cell NHL — A Phase 1/2 study of ronde-cel (CD19/CD20 dual-targeting CAR T) in aggressive B-cell non-Hodgkin lymphoma.
  • 2026-01-12 · Phase 3 start for ronde-cel in large B-cell lymphoma (2L setting) — PiNACLE-H2H: a randomized controlled trial of ronde-cel vs investigator's choice of CD19 CAR T in second-line large B-cell lymphoma.
Risks & what to watch (4)›

Key risks

  • No revenue, ongoing losses — Zero revenue and net loss of $44.8M in latest quarter (2026-06-30) [sec].
  • Cash runway uncertainty — Cash of $73.0M (2026-06-30) may be insufficient to complete multiple Phase 3 trials [sec].
  • Phase 3 head-to-head risk — PiNACLE-H2H pits ronde-cel against two approved CAR T therapies, increasing trial risk [sec_mda · as of 2026-08-06].
  • Solid tumor program early stage — LYL273 is in Phase 1/2 with proof-of-concept from a single investigator-sponsored trial in China [sec_mda · as of 2026-08-06].

What to watch

  • PiNACLE-H2H enrollment progress and event-free survival data [sec_mda · as of 2026-08-06].
  • PiNACLE pivotal data expected mid-2027 and BLA submission in second half of 2027 [sec_mda · as of 2026-08-06].
  • Phase 1/2 data presentations for ronde-cel at upcoming medical meetings (e.g., EHA 2026) [news · published 2026-06-04].
