Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • For Phase 1, subjects with or cytologically confirmed advanced or solid tumors that have failed prior standard therapy (disease progression; subject intolerance is also allowable).
  • For Phase 2, subjects with the following tumor types who meet protocol-defined criteria: advanced or metastatic NSCLC, melanoma, urothelial carcinoma, SCCHN, SCLC, and CRC.
  • Presence of at least 1 by computed tomography or magnetic resonance imaging per v1.1.
  • (ECOG) performance status 0 to 1.
  • Resolution of all toxicities and any toxic effect(s) of the most recent prior therapy to Grade 1 or less (except alopecia). Subjects with ≤ Grade 2 neuropathy are an exception and may enroll.
  • Adequate renal, hepatic, and hematologic functions per protocol-defined laboratory parameters within ≤ 7 days before treatment initiation.

Exclusion criteria

Exclusion Criteria:

  • Participation in any other study in which receipt of an study drug or device occurred within 2 weeks or 5 half-lives (whichever is longer) before first dose.
  • Has received a prior monoclonal antibody within 4 weeks or 5 half-lives (whichever is shorter) before administration of study drug.
  • Prior chemotherapy or targeted small molecule therapy within 2 weeks before administration of study treatment.
  • Prior therapy with an IDO1 or arginase 1 inhibitor.
  • Active disease that has required systemic treatment in past 2 years. Replacement therapy (eg, thyroxine, insulin, or physiologic replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
  • Receipt of a within 30 days before the first dose of study treatment.
  • Any history of serotonin syndrome after receiving serotonergic drugs.
  • Use of protocol-defined prior/concomitant therapy.
  • Known or suspected defect in the function of the urea cycle.
  • History of gastrointestinal condition that may affect drug absorption.
Terms in these criteria, in plain language(9)

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.

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

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.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

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 May 21, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
