Study of Rondecabtagene Autoleucel in Aggressive Large B-Cell Lymphoma

A Phase 1/2 interventional study of Rondecabtagene autoleucel (ronde-cel) and Fludarabine in Relapsed Non-Hodgkin Lymphoma, Refractory Non-Hodgkin Lymphoma and Non-Hodgkin Lymphoma, sponsored by Lyell Immunopharma, Inc.. Recruiting at 35 sites in 2 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-25.

  1. The study's listed conditions name Lymphoma, B-Cell, a narrower term within Lymphoma, Non-Hodgkin.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This is a Phase 1/2, multi-center, open-label study evaluating the safety and efficacy of rondecabtagene autoleucel (ronde-cel) also known as LYL314, a dual-targeting chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 and CD20 in participants with aggressive large B-cell lymphoma.

Read the detailed description

This is a Phase 1/2, multi-center, open-label study evaluating the safety and efficacy of ronde-cel, a dual-targeting chimeric antigen receptor (CAR) targeting cluster of differentiation (CD)19 and CD20 in participants with aggressive large B-cell lymphoma.

Five cohorts of participants will be enrolled:

Cohort 1: (3rd or later line, 3L+) Participants who have received least two prior lines of treatment

Cohort 2: (CAR T-cell experienced, 3L+): Participants who have received at least two prior lines of treatment including one prior CAR T.

Cohort 3: (second line, 2L) Participants with refractory disease or relapse within one year of first-line therapy (second-line).

Cohort 4: (TCE-experienced, 3L+) Participants have received prior T-cell engager therapy and have received at least two prior lines of treatment including one TCE therapy and have not received prior CAR T.

Cohort 5: (high-risk 1st line) Participants receiving first-line treatment who remain with disease on positron emission tomography scanning (PET-positive) after 2 to 3 cycles of standard-of-care chemoimmunotherapy and have not received prior CAR T.

Up to approximately 150 participants (across all cohorts) will be enrolled in the dose finding Phase 1 part of the study.

The Phase 2 pivotal study (PiNACLE) will expand enrollment of Cohort 1 to approximately 120 participants to further evaluate the safety and efficacy of ronde-cel.

Ronde-cel treatment consists of a single administration of CAR transduced autologous T-cells administered intravenously after a conditioning chemotherapy regimen consisting of fludarabine and cyclophosphamide, administered over 3 days.

Individual participants will remain in the active post-treatment follow-up (PTFU) period for approximately 2 years. Participants will continue in long-term follow-up (LTFU) for 15 years from ronde-cel treatment.

Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2023 (actual). Primary completion is estimated for Dec 2028, 67 months after the start.

Of 94 phase 1/2 interventional studies under Lymphoma, B-Cell, half reached primary completion within 71 months of starting (the median), counting those still running; a quarter within 55 and three quarters within 96. This study's planned 67 months is close to that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 25, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
