Study summary

This is a phase II single-arm study of low-dose pembrolizumab (100mg, fixed-dose) plus chemotherapy in women aged 18 years or older with histologically confirmed persistent, recurrent, or metastatic cervical cancer who are ineligible for curative-intent treatment (surgery and/or radiation therapy) and who have not been previously treated with systemic chemotherapy, with the exception of chemotherapeutic agents used as radiosensitizers (cisplatin or carboplatin concurrent with radiation therapy).

Read the detailed description

This is a phase II single-arm study of low-dose pembrolizumab plus chemotherapy in women aged 18 years or older with histologically confirmed persistent, recurrent, or metastatic cervical cancer who are ineligible for curative-intent treatment (surgery and/or radiation therapy) and who have not been previously treated with systemic chemotherapy, with the exception of chemotherapeutic agents used as radiosensitizers (cisplatin or carboplatin concurrent with radiation therapy).

Participants must have measurable disease as defined by RECIST 1.1, as assessed by the local investigator/radiologist, and must provide a tumor tissue sample no older than 4 years for PD-L1 expression status determination. PD-L1 expression will be analyzed using the 22C3 antibody (Dako®) and classified according to the Composite Positive Score (CPS).

Treatment will consist of pembrolizumab 100mg administered by intravenous infusion plus chemotherapy every 3 weeks. Chemotherapy may be paclitaxel 175 mg/m2 plus carboplatin AUC 5 or paclitaxel 175 mg/m2 plus cisplatin 50 mg/m2 for patients not previously exposed to cisplatin. Both carboplatin and cisplatin should be administered immediately after paclitaxel. All study treatments should be administered on Day 1 (D1) of each 3-week treatment cycle. All participants should receive premedication to prevent severe hypersensitivity reactions according to local practice. Premedication should be administered after the pembrolizumab infusion and before chemotherapy.

During the treatment period, participants will have routine clinical visits for treatment administration, safety and well-being monitoring, and assessment of disease status changes.

Primary safety assessments will include physical examinations, vital signs, electrocardiography (ECG), hematology and biochemistry tests, thyroid function tests, and urinalysis. At each visit, adverse events will be assessed and graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 1 5.0. Study treatment doses may be interrupted or reduced (applicable only to chemotherapy) or discontinued in case of severe adverse events.

Imaging assessments will include computed tomography (CT) of the chest and magnetic resonance imaging (MRI) of the abdomen and pelvis. The first study imaging assessment will be performed at 9 weeks (63 days ± 7 days) from the date of Cycle 1 (C1) Day 1 infusion. Subsequent imaging should be performed every 9 weeks (63 days ± 7 days) until Week 54 and every 12 weeks (84 days ± 7 days) thereafter. Other imaging exams such as bone scintigraphy or brain imaging should be performed as clinically indicated.

Participants may interrupt or discontinue pembrolizumab and continue in the study. Similarly, participants may interrupt or discontinue chemotherapy and continue treatment with pembrolizumab.

Participants will receive study treatments until disease progression as defined by RECIST 1.1, unacceptable toxicities, intercurrent illness that precludes continued treatment, investigator's decision to withdraw the participant from treatment, withdrawal of consent, or administrative reasons requiring treatment discontinuation.

Participants may receive up to 6 cycles of paclitaxel-platinum (carboplatin or cisplatin). Participants may receive a maximum of 35 administrations of pembrolizumab (approximately 2 years). In the case of complete response (CR), study treatment may be discontinued at the investigator's discretion after the CR has been confirmed by radiographic imaging and the participant has received at least 2 cycles of pembrolizumab and to have completed a minimum of 8 total treatment cycles (approximately 24 weeks).

Participants who discontinue study treatment for reasons other than radiographic disease progression will be followed until documented disease progression by RECIST 1.1 criteria, initiation of new anticancer therapy, withdrawal of consent, loss to follow-up, or death.

After discontinuation of study treatment, participants may initiate subsequent anticancer treatments at the discretion of the treating physician and in accordance with local standard of care.

After verification of disease progression by RECIST 1.1 and/or initiation of subsequent oncological treatment, all participants will be followed up for overall survival (by telephone contact or in-person visits to the center) until withdrawal of consent, loss to follow-up, death, or until the study is completed or terminated early, whichever occurs first.

Symptomatic improvement is a recognized clinical benefit. Participants will complete the EuroQol EQ-5D-5L, EORTC QLQ-C30, and EORTC QLQ-CX24 to assess quality of life.

The study will begin when the first participant signs the Informed Consent Form and will end when the last participant completes the final study-related call or visit, withdraws from the study, or is lost to follow-up (i.e., the participant cannot be contacted by the investigator).

Terms in these criteria, in plain language(28)

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

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.

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.

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.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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.

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.

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.

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

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.

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.

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 Feb 24, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
