Study summary

This is a phase 2 study whose purpose is see how useful investigational drug, avelumab, is in patients with locally advanced or metastatic penile cancer who are unfit for or progressed on platinum-based chemotherapy.

The usefulness of avelumab in this study population will be determined by anti-tumor activity assessed by objective response rate.

Avelumab is a monoclonal antibody that binds to a protein called programmed death-ligand 1 (PD-L1) and blocks its communication with another protein called programmed death protein 1 (PD-1). The communication of these proteins are thought to be important in the growth of tumors. Blocking these proteins from communicating may stop or shrink tumors.

Terms in these criteria, in plain language(10)

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.

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.

iRECIST and mRECIST

Versions of RECIST adapted to particular cases. iRECIST is for immunotherapy, where a tumour can look bigger for a while before it shrinks, so growth has to be confirmed on a later scan. mRECIST usually means the version for liver cancer (hepatocellular carcinoma), which measures only the part of a tumour that still has a blood supply.

Metastases

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

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.

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.

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.

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Interventions

  • Avelumab is a fully human monoclonal antibody (mAb) of the immunoglobulin (Ig) G1 isotype. Avelumab selectively binds to programmed death-ligand 1 (PD-L1) and competitively blocks its interaction with programmed death protein 1 (PD-1).

What researchers measure

Primary outcomes

  1. Objective Response Rate

    To demonstrate the anti-tumor activity of avelumab by objective response rate (ORR) according to Immune-related Response Evaluation Criteria in Solid Tumors (iRECIST) in patients with locally advanced or metastatic penile carcinoma unfit for platinum-based chemotherapy or progressed on or after platinum-based chemotherapy.

    Time frame: 3 years

  2. Overall Survival Rate

    Assess the overall survival (OS) of avelumab in patients determined to have PD-L1-positive tumors (including infiltrating immune cells) by the GMP verified Dako PD-L1 IHC 22C3 pharmDx test with thresholds of \<1%, 1-49%, and ≥ 50% to define PD-L1 positivity, and in all enrolled patients

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

Started Aug 2018 (actual). Primary completion is estimated for Dec 2026, 100 months after the start.

Of 28 phase 2 interventional studies under Penile Neoplasms, half reached primary completion within 63 months of starting (the median), counting those still running; a quarter within 35. This study's planned 100 months is above that.

How these figures are worked out, and which studies are left out of them.

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 Jul 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
