Study summary

This is a Phase 1/2, multi-center, open-label study of CPI-1205 + ipilimumab in patients with histologically or cytologically confirmed advanced solid tumors. This study is designed to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of CPI-1205 + ipilimumab in patients with advanced solid tumors. Patients in Phase 2 will be treated at the RP2D of CPI-1205 + ipilimumab.

This study was stopped prior to proceeding to Phase 2; no patients were enrolled in Phase 2.

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.

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.

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.

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.

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.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

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.

What researchers measure

Primary outcomes

  1. Phase 1: Frequency of Dose-limiting toxicities (DLTs)

    The RP2D will be selected based on the PK, pharmacodynamics and overall tolerability of the regimen, but will not exceed the MTD.

    Time frame: 1 year

  2. Phase 2: Objective response rate

    The rate of confirmed complete responses (CR) + partial responses (PR) as determined by RECIST 1.1 criteria

    Time frame: 1 year

Secondary outcomes

  1. Objective response rate

    The rate of confirmed iCR + iPR

    Time frame: 1 year

  2. Clinical Benefit Rate

    The rate of CR + PR + stable disease (SD) after 3 months of treatment as determined by RECIST 1.1 criteria and as the rate of iCR + iPR + iSD after 3 months of treatment by iRECIST criteria

    Time frame: 3 months

  3. Time to response

    The time from day (D) 1 of treatment to the date of first response as determined by RECIST 1.1 and iRECIST criteria

    Time frame: 1 year

  4. Duration of Response

    The time from measurement criteria are first met for CR/PR or iCR/iPR (whichever is first recorded) until the date of recurrence or progressive disease as determined by RECIST 1.1 and iRECIST criteria

    Time frame: 1 year

  5. Duration of treatment

    The time from D1 of treatment until the date treatment is discontinued for any reason

    Time frame: 1 year

  6. Progression free survival

    The time from D1 of treatment to the date of progression or death, whichever occurs first with progressive disease as determined by RECIST 1.1 and iRECIST criteria

    Time frame: 6 months

  7. Adverse Events

    AEs will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events version 4.03 (CTCAE v4.03).

    Time frame: 1 year

Timeline

Tracking since Sep 25, 2026
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

Ran from Dec 2017 to primary completion in Jun 2019, 17 months.

Of 677 industry-sponsored phase 1 interventional studies under Neoplasms, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 61. This study's 17 months is below that.

Counting every sponsor, half of 903 studies reached it within 40 months; a quarter within 23 and three quarters within 64.

Neoplasms covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

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 18, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
