Study summary

Immune checkpoint inhibitors (ICI) have revolutionized the management of advanced cancers. However, most rare cancers have been excluded from this progress due to the lack of clinical trials involving these diseases. After the standard first-line treatment, there are no other validated treatments for most of them. The management of these patients in ≥ 2nd line treatment relies on historic poorly effective regimens.

This creates an inequity between patients with frequent cancers beneficiating from medical progresses and approvals of innovative drugs, and patients with rare cancers are still treated with old and toxic drugs.

Few available data on case reports and early phase studies indicate a beneficial role of the immunotherapy in rare cancers.

The investigators assume that the combination of Domvanalimab and Zimberelimab is more effective than historical standard treatments in patients with 5 types of advanced rare cancers, after failure of at least one line of standard treatment in the advanced setting:

  • Cohort 1: Peritoneal Mesotheliomas (PM)
  • Cohort 2: Gestational Trophoblastic Tumors (GTT)
  • Cohort 3: Thymic Carcinomas (TC)
  • Cohort 4: Refractory Thyroid Carcinomas (ATC)
  • Cohort 5: GEP-NET and carcinoid tumors (GEP-NET (Gastroenteropancreatic neuroendocrine tumors)/TCT (Thoracic carcinoid tumor)/UP-NET (Neuroendocrine tumor of unknown primary))

The primary objective is to assess the efficacy of the combination of Domvanalimab and Zimberelimab in terms of progression-free survival rate at 24 weeks (for cohorts 1,3,5), successful hCG (Human Chorionic Gonadotropin) normalisation rate at 24 weeks for cohort 2 and survival rate for cohort 4.

The secondary objectives are to assess the efficacy of the combination of anti-TIGIT (T cell Immunoreceptor with Ig and ITIM domains) and anti-PD-1 (Programmed Death-1) immunotherapies in terms of overall response rate, progression-free survival (cohort 1-3 and 5), resistance-free survival (cohort 2), overall survival (cohorts 1-3 and 5), duration of the response (cohorts 1-3 and 5); and to assess the tolerability of the doublet of immunotherapy in terms of adverse events.

Patients will be treated until disease progression or alternatively 2 years in case of complete response (upon discussion with the coordinator of the study, the coordinator of the cohort and the investigator), unacceptable toxicity, or death. At the end of treatment, patients will be followed up for at least 1 year.

IMMUNORARE5 is composed of five independent open-label national multicenter single-arm phase II trials, sponsored by Lyon University Hospital, led in collaboration with the corresponding French national reference centers, with a centralized coordination by a dedicated team.

Each phase II trial is designed as a two-stage Simon design, with early termination for futility. For each cohort, a null hypothesis (H0) and an alternative hypotheses (H1) regarding the percentages of patients with success has been defined, with 5% one-sided alpha level and 80% power.

The trial will be conducted in 15 French Centers with an inclusion period of 36 months

(For example, patients with autoimmune disease that requires systemic steroids or immunosuppression agents should not to be included. Replacement therapy (eg., thyroxine, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.)
  • Uncontrolled intercurrent illness, including but not limited to, congestive heart failure; respiratory distress; liver failure; allergy; psychiatric illness/social situations that would limit compliance with study requirement according to the investigator, or that substantially increase risk of incurring AEs or compromise the ability of the patient to give written .

An exception applies for palliative radiotherapy administered locally to control local symptoms likely to compromise the patient functional status (e.g., pain, compression, hemorrhage), as such treatment is not expected to interfere with the assessment of the efficacy or safety of the systemic therapy given concurrently.

For patients with rapidly progressive that may fast compromise their vital status, a minimum interval of two weeks between the last cycle of platinum-based chemotherapy (with or without concurrent radiotherapy) or the last day of radiotherapy, and the start of study treatment, is acceptable, upon approval by one of the two coordinators of the cohort.

Terms in these criteria, in plain language(29)

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.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

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.

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.

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.

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.

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.

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.

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.

Metastases

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

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

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.

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.

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.

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.

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.

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.

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.

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.

    Time frame: At 24 weeks after the start of study treatments

  3. Survival rate (cohort 4)

    Proportion of patients alive at 24 weeks (percent).

    Time frame: At 24 weeks after the start of study treatments

Secondary outcomes

  1. Overall response rate (cohorts 1, 3, 4 and 5)

    Overall response rate defined as the proportion of patients experiencing complete or partial radiological response as the best radiological tumor response on the study period according to RECIST 1.1 for cohorts 3-5 and mRECIST for cohort 1.
