Study summary

This is a single-center, correlative pilot study evaluating potential biomarkers predictive of immune-related adverse events associated with immune checkpoint inhibitor therapy.

Read the detailed description

This is a single-center, correlative pilot study evaluating potential biomarkers predictive of immune-related adverse events associated with immune checkpoint inhibitor therapy. The study includes a control population of patients receiving standard chemotherapy as a comparator. Patients will undergo blood draws at 4 time-points while on standard of care treatment. There are no study-related medications or interventions beyond blood sampling.

In context

Neoplasms

10,824 studies on the registry are indexed under Neoplasms; 2,325 are open to participants now.

This study's planned enrollment of 69 is below the median of 200 across 2,641 observational studies indexed under Neoplasms.

Study population

These patients will be enrolled only at the University of Colorado Cancer Center in the outpatient clinic setting.

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

  1. solid tumor cancer of any primary site, with the exception of lymphoma
  2. ≥18 years of age
  3. >6 months
  4. Starting new regimen of ipilimumab, nivolumab, pembrolizumab or atezolizumab as a single agent or in combination according to standard of care or through compassionate use granted by the pharmaceutical company ( arm only) OR Starting new regimen of standard cytotoxic chemotherapy (control arm only)
  5. Provision to sign and date the consent form
  6. Stated willingness to comply with all study procedures and be available for the duration of the study

Exclusion criteria

Exclusion Criteria:

  1. Prior therapy with anti-CTLA4, anti-PD1 or anti-PD-L1 targeting agent
  2. Known disease
  3. Known acute or chronic infection, including viral infections such as , C, and
  4. Chronic treatment with immune suppressive medications, including , at the time of study enrollment
  5. Concomitant treatment with a monoclonal antibody in addition to cytotoxic chemotherapy (i.e. bevacizumab, cetuximab, trastuzumab) (control arm only)
  6. Known pregnancy or lactation
Terms in these criteria, in plain language(7)

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.

Metastases

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

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

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.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

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.

Groups and cohorts

  • Immune Checkpoint Inhibitor Therapy

    Patients starting treatment with ipilimumab, nivolumab, pembrolizumab, or atezolizumab, alone or in combination, for treatment of a metastatic solid tumor cancer will be enrolled. Patients will receive checkpoint inhibitor therapy per standard protocol. There are no study-related medications or interventions beyond blood testing.

    Other: Blood Testing

  • Control

    An additional 18 patients starting standard chemotherapy will be enrolled as a control population. Patients will receive chemotherapy per standard protocol

    Other: Blood Testing

Interventions

  • OtherBlood Testing

    Patients will undergo therapy per standard protocol. There are no study-related medications or interventions beyond blood testing.

This study also gives Pembrolizumab, Nivolumab, Ipilimumab, Atezolizumab. No intervention listed here names it: that was found by reading the record.

What researchers measure

Primary outcomes

  1. Identifying biomarkers predictive of immune-related toxicity associated with immune checkpoint inhibitor therapy.

    Difference in baseline inflammatory/autoimmune marker(s) in patients developing immune-related adverse events on immune checkpoint inhibitor therapy according to CTCAE v 4.0 versus those who do not

    Time frame: 30 Months

Secondary outcomes

  1. Change in inflammatory/autoimmune markers.

    To evaluate the change in inflammatory/autoimmune markers prior to and at 3 time points on immune checkpoint inhibitor therapy, with comparison to patients treated with standard chemotherapy

    Time frame: 6 Months

  2. Change in inflammatory/autoimmune markers

    To evaluate the impact of change in these markers on patient reported adverse events using the PRO-CTCAE

    Time frame: 6 months

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 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
