Study summary

This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of non-muscle invasive bladder cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving pembrolizumab with radiation may kill more tumor cells than chemotherapy with radiation therapy in patients with non-muscle invasive bladder cancer.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM 1: Patients receive one of the following chemotherapy regimens per physicians choice: 1) cisplatin intravenously (IV) once per week for 4 weeks, 2) gemcitabine IV on days 1, 4, 8, 11, 15, 18, 22, and 25, or 3) mitomycin IV on day 1 and 5-fluorouracil IV continuously over 120 hours on days 1-5 and 16-20. Patients receiving cisplatin or gemcitabine continue chemotherapy for 6 weeks if they are receiving radiation according to the standard hypofractionated radiation schedule. Starting on day 1, patients also receive radiation therapy for 20, 32, or 36 treatments over 4-7 weeks. Treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT)/magnetic resonance imaging (MRI) and blood sample collection throughout the study. Patients may also undergo optional urine sample collection on study.

ARM 2: Patients receive pembrolizumab IV over 25-40 minutes on day 1 of each cycle. Cycles repeat every 6 weeks for 9 cycles in the absence of disease progression or unacceptable toxicity. Starting on day 1, patients also receive radiation therapy for 20, 32, or 36 treatments over 4-7 weeks. Treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo CT/MRI and blood sample collection throughout the study. Patients may also undergo optional urine sample collection on study.

After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years and then annually for 5 years.

Terms in these criteria, in plain language(23)

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.

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.

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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).

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.

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.

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.

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.

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

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.

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.

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.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

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.

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.

Excipients

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

What researchers measure

Primary outcomes

  1. Bladder intact event-free survival (BIEFS)

    Defined as time free of histologically proven recurrent T1-T4 recurrence, clinical evidence of nodal or distant metastasis, radical cystectomy (either for disease progression or due to toxicity), or death from any cause. Analysis will consist of estimation of the BIEFS curves via the Kaplan-Meier estimator and testing of the primary hypothesis using the stratified logrank test (one-sided). Additionally, the Cox proportional hazards model will be used to estimate the hazard ratio adjusting for stratification variables and any other baseline covariates that demonstrate any degree of imbalance by treatment arm.

    Time frame: Up to 5 years

  2. Global quality of life

    Assessed using European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30) global quality of life domain.

    Time frame: Up to 5 years

Secondary outcomes

  1. Complete response by cystoscopy

    The proportion achieving complete response will be compared using the two-sample binomial test. Further analysis may consist of using a binary outcome regression model (i.e., logistic regression) to compute the relative odds of response adjusted for any factors that may appear imbalanced by treatment arm.

    Time frame: At 6 months

  2. Disease free survival

    Defined in standard specification as time free of any disease failure (local/regional/distant), or death from any cause. Will be evaluated via the Kaplan-Meier estimator and logrank test.

    Time frame: Up to 5 years

  3. Local-regional control

    Will be estimated via the cumulative incidence estimator, treating death as a competing event.

    Time frame: Up to 5 years

  4. Metastasis free survival

    Will be evaluated via the Kaplan-Meier estimator and logrank test.

    Time frame: Up to 5 years

  5. Overall survival

    Will be estimated via the Kaplan-Meier estimator.

    Time frame: Up to 5 years

  6. Quality of life

    Assessed using the Bladder Cancer Index and EORTC-QLQ-C30.

    Time frame: Up to 2 years

  7. Incidence of adverse events (AE)

    Assessed using the Common Terminology Criteria for Adverse Events. Counts and frequencies will be reported for the worst grade per AE experienced per patient by treatment arm. Differences in frequency by treatment arm of AE grade, singly or grouped into larger categories (for example, grade 3 or higher vs lower) with be tested using a chi-squared test or Fisher's exact test with a significance level of 0.05.

    Time frame: Up to 3 years

  8. Bladder specific quality of life

    Using the Bladder Cancer Index.

    Time frame: Up to 2 years

Other outcomes

  1. Quality adjusted survival

    Index scores from the European Quality of Life Five Dimension Five Level Scale will be calculated at each time point and change from baseline to post-treatment scores compared between treatment arms using a t-test with a 2-sided significance level of 0.05. If there are significant differences, then a quality-adjusted life year (QALY) analysis will be conducted. QALYs are defined by the weighted sum of different time episodes added up to a total quality-adjusted survival time. The difference in QALYs between arms will be reported along with the 95% confidence interval.

    Time frame: Up to 2 years

  2. Fatigue

    Using Patient Reported Outcomes Measurement Information System Fatigue-4A. Calculated by summing all 4 questions (all 4 questions are required to be completed to score the tool). Raw scores range from 4 to 20 and are standardized to a T score following the scoring instructions.

    Time frame: Up to 2 years

  3. Cumulative global quality of life

    Using the EORTC-QLQ-C30 and Bladder Cancer Index.

    Time frame: Up to 2 years
