Study summary

This is an open-label, multicenter, single-arm Phase 2 clinical trial evaluating neoadjuvant pucotenlimab (anti-PD-1 immunotherapy) combined with becotatug vedotin (EGFR-targeted antibody-drug conjugate, ADC) for adults with locally advanced penile squamous cell carcinoma. Eligible patients have high-risk disease defined as T4 primary tumor with any nodal status or any T stage with N2-N3 lymph node metastasis and no distant metastasis.

All participants receive up to 4 cycles of combination neoadjuvant therapy every 3 weeks. After treatment completion, a multidisciplinary team will assess if consolidative surgery can be performed. Patients who undergo surgery will continue single-agent pucotenlimab adjuvant treatment for 17 additional cycles (approximately 1 year).

The primary goal is to measure the pathological complete response (pCR) rate. Secondary goals include objective response rate (ORR), progression-free survival (PFS),overall survival (OS) and safty profiles. Blood and tumor tissue samples will be collected to explore biomarkers that may predict treatment response and drug resistance. A total of 29 male patients will be enrolled.

Read the detailed description

Background:

Penile squamous cell carcinoma is a rare genitourinary malignancy with poor outcomes once regional lymph node spread occurs. Up to 45% of patients present with nodal metastasis at initial diagnosis. Patients with pelvic lymph node involvement (N3) have a 0-17% 5-year survival rate, and 86% of locally advanced patients experience recurrence within 2 years after standard surgery alone. The guidelines recommended neoadjuvant chemotherapy regimen (paclitaxel, ifosfamide, cisplatin, TIP) yields only a 10% pathological complete response rate, with limited long-term disease control and short survival after disease progression.

Over 90% of penile squamous cell carcinomas overexpress EGFR, and 40%-60% of patients show PD-L1 positivity, supporting dual targeting of EGFR and PD-1 as a promising therapeutic strategy. Preclinical and early clinical data confirm synergistic anti-tumor activity between EGFR ADCs and PD-1 inhibitors: the ADC payload promotes dendritic cell maturation and antigen presentation, while PD-1 blockade restores anti-tumor T cell function. Previous prospective trials demonstrate that this combination produces meaningful tumor regression and survival outcomes in other squamous cell carcinomas, with manageable toxicities.

This trial adopts a Simon two-stage single-arm design to efficiently test the study regimen's anti-tumor activity without a separate control group. If the first 10 enrolled patients show minimal pathological response, the trial will stop early for futility; otherwise, enrollment will continue to a total of 29 subjects to generate robust efficacy and safety data for this chemotherapy-free neoadjuvant platform.

Safety Oversight:

All adverse events are monitored from enrollment through 28 days after the last study drug dose, graded per CTCAE v5.0. All serious adverse events (SAEs) must be reported to the institutional review board and study sponsor within 24 hours. Standard supportive care, including growth factors for cytopenias, antihistamines and corticosteroids for infusion reactions, and symptom-directed management for immune-related toxicities and peripheral neuropathy, is permitted throughout treatment. Dose modification rules are pre-specified: pucotenlimab cannot be dose-reduced and may only be held or permanently discontinued, while becotatug vedotin allows one dose level reduction for persistent tolerability issues before permanent discontinuation.

A clinical trial liability insurance policy covers study participants for injuries causally related to investigational treatment, in accordance with Chinese clinical research regulations. A dedicated ethics committee hotline is available for participants to raise concerns regarding study participation, rights, or adverse events.

Biospecimen Research:

Collected blood and tumor tissue specimens are anonymized with unique study identifiers to protect participant privacy. No identifiable personal health information will be included in sequencing or laboratory testing. Biomarker analyses include HPV subtyping, PD-L1/EGFR immunohistochemistry, immune cell subset profiling, and multi-omic sequencing (single-cell transcriptomics, spatial transcriptomics, whole-exome and bulk RNA sequencing). Patient-derived xenograft (PDX) models will be established from residual tumor tissue to explore molecular mechanisms of treatment resistance. All biospecimens will be destroyed upon completion of planned exploratory analyses, with no long-term indefinite storage. Biomarker sub-study results will only be published in aggregate, without individual participant data disclosure.

Follow-Up:

After completing neoadjuvant and adjuvant therapy, participants enter a multi-year surveillance phase. Imaging assessments occur every 3-6 months for the first two years post-treatment completion, then annually from year three through year five. Remote telephone follow-up is allowed between scheduled hospital visits to track disease status, subsequent anti-cancer therapies, and overall survival. All participants who discontinue study treatment early-whether due to withdrawal, disease progression, or toxicity-remain in long-term survival follow-up to avoid missing survival endpoint data.

Terms in these criteria, in plain language(16)

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.

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.

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.

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.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

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.

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.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

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.

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.

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.

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.

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.

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 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
