Study summary

The main objective is to demonstrate that the addition of neoadjuvant and adjuvant immunotherapy with durvalumab, to standard neoadjuvant chemotherapy (with cisplatin/gemcitabine) and surgery in urothelial carcinoma could improve event-free survival.

Read the detailed description

Despite optimal surgical management the prognosis for localized muscle invasive urothelial cancer (MIUC) is unfavorable with 5-year overall survival of around 45%.

According to international guidelines the use of cisplatin-based neoadjuvant chemotherapy is considered standard of care in all patients with localized MIUC with planned curative local treatment.

However, the benefit of neoadjuvant chemotherapy is limited and there is a clear medical need for improvement for this patient population.

Durvalumab has been tested in a phase I/II open-label study including patients with metastatic urothelial cancer (mUC).

The results demonstrated an overall response rate (RR) of 31% in 42 response-evaluable patients. The side effect profile was favorable with most common grade 1/2 AE representing fatigue (13%), diarrhea (10%) and decreased appetite (8%). Three patients (4.9%) had treatment related grade 3 AE's, no grade 4/5 events were noted.

The combination of cisplatin/gemcitabine chemotherapy with modern immune-checkpoint inhibition has been demonstrated to be feasible with demonstration of favorable immunomodulatory effects.

In view of these data it appears a logical step to apply these novel agents in the curative setting of neoadjuvant treatment.

The expected benefit of combining chemotherapy with durvalumab and to continue durvaluamb postoperatively might be twofold:

  • to increase the response rate in the pre-operative setting and subsequently to increase the rate of pathologic complete remission (pT0) and to reduce risk of local recurrence
  • to evoke durable systemic anti-cancer responses and subsequently to increase disease free- and overall survival and furthermore to induce antitumor immune response.

Terms in these criteria, in plain language(27)

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.

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.

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.

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.

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).

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.

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.

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.

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

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.

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.

Metastases

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

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.

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.

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.

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 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.

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.

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.

Excipients

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

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

What researchers measure

Primary outcomes

  1. event-free survival (EFS)

    The primary endpoint of the trial is Event-free survival (EFS) at 2 years after neoadjuvant trial treatment start. Event-free survival is defined as the time from treatment start until one of the following events, whichever comes first: * Progression during neoadjuvant treatment leading to inoperability * Recurrence of locoregional disease after surgery * Appearance of metastases at any localization * Death Patients not experiencing an event will be censored at the date of the last available assessment before initiation of a subsequent treatment, if any.

    Time frame: 2 years after treatment start

Secondary outcomes

  1. Event-free survival (EFS)

    Event-free survival is defined as the time from treatment start until one of the following events, whichever comes first: * Progression during neoadjuvant treatment leading to inoperability * Recurrence of locoregional disease after surgery * Appearance of metastases at any localization * Death Patients not experiencing an event will be censored at the date of the last available assessment before initiation of a subsequent treatment, if any.

    Time frame: at the occurrence of the event or latest 5 years after surgery

  2. Recurrence-free survival (RFS) after R0 resection

    RFS after R0 resection is defined as the time from surgery until one of the following events, whichever comes first: * Recurrence of locoregional disease * Appearance of metastases at any localization * Death Patients not experiencing an event will be censored at the date of the last available assessment before initiation of a subsequent treatment, if any. This endpoint will only be calculated for patients in the R0 resection set.

    Time frame: at recurrence or latest 5 years after surgery

  3. Overall survival (OS)

    Overall survival is defined as the time from treatment start until death from any cause. Patients not experiencing an event will be censored at the last date they were known to be alive.

    Time frame: at death or latest 5 years after surgery

  4. Quality of resection

    The quality of resection will be assessed in the following way: * Complete resection (R0) defined as free resection margins proved microscopically * Completeness of the lymphadenectomy and surgery using the photo documentation and histopathology * Postoperative complications will be assessed using the Clavien-Dindo classification

    Time frame: after surgery or the latest 20 weeks after registration

  5. Pathological complete response rate (ypT0)

    Pathological complete response (ypT0) is defined as no residual tumor in the surgical specimen. The proportion of patients with ypT0 will be calculated for patients in the resected patients set.

    Time frame: after surgery or the latest 20 weeks after registration

  6. Pathological response rate (PaR) defined by pathological downstaging to ≤ypT1N0M0

    Pathological response (PaR) is defined as pathological downstaging to ≤ ypT1N0M0. The proportion of patients with PaR will be calculated for patients in the resected patients set.

    Time frame: after surgery or the latest 20 weeks after registration

  7. Pattern of recurrence

    Pattern of recurrence is defined as location of first tumor recurrence. Patterns can be locoregional or distant or any combination of these patterns. Patients with secondary malignancies or patients with no recurrence will not be taken into consideration for this endpoint.

    Time frame: after recurrence or latest 5 years after surgery

  8. Treatment feasibility

    The following feasibility criteria will be assessed: * completion of 4 cycles of neoadjuvant chemotherapy * completion of 4 cycles of neoadjuvant durvalumab treatment * timely admission to and completion of planned surgery * timely initiation and completion of 10 cycles of adjuvant durvalumab treatment

    Time frame: after treatment end or the latest 73 weeks after registration

  9. Adverse events

    All AEs will be assessed according to NCI CTCAE v4.03

    Time frame: within treatment start and 90 days after last trial treatment and resolution of all related AEs thereafter (at the latest 5 years after surgery)

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 May 2018 to primary completion in Feb 2022, 45 months.

Of 335 non-industry phase 2 interventional studies under Neoplasms, half reached primary completion within 58 months of starting (the median), counting those still running; a quarter within 36 and three quarters within 99. This study's 45 months is below that.

Counting every sponsor, half of 514 studies reached it within 52 months; a quarter within 33 and three quarters within 92.

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

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.
