Study summary

In metastatic NSCLC patients with PD-L1 expression ≥50%, a circulating immature (CD10-) LDNs level of ≥30.5% confers a high risk of hyperprogression (HPD) with first line single-agent immune-checkpoint inhibitors (SA-ICI). HPD is defined as a tumor growth rate (TGR) delta ≥50% between pre-treatment and post-treatment, and/or a TGR ratio ≥2. The combination of platinum-based chemotherapy (PCT) with ICI in this setting could prevent the occurrence of HPD and ultimately improve survival outcomes.

This randomized, multicentric, open-label, phase 2 trial will include patients with stage IV NSCL, without targetable oncogene drivers, PD-L1 TPS≥50%, and measurable disease on two CT scans performed before randomization. Participants will be randomized 1:1 to SA-ICI or ICI+PCT. Radiological evaluation will be performed by CT-scan at 6-8 weeks and subsequently according to the local investigators' schedule.

In the SA-ICI arm, ICI regimen will include cemiplimab. In the PCT+ICI arm, PCT regimens will include both carboplatin or cisplatin + pemetrexed (for non-squamous histology) or paclitaxel (for squamous histology) in combination with cemiplimab.

PCT will be administered for three cycles. In case of stable disease or partial response according to RECIST v.1.1, cemiplimab will be performed as monotherapy from the third cycle until disease progression or unacceptable toxicity. If progression according to RECIST v.1.1 or HPD after three cycles of PCT+ICI, patients will be treated with standard second line therapy as local standard of care.

Read the detailed description

Intervention: PCT plus cemiplimab for 3 cycles followed by cemiplimab in case of absence of PD/HPD. PCT regimens will include both carboplatin (area under the concentration-time curve, 5 mg per milliliter per minute) or cisplatin (75 mg per square meter of body surface area) plus pemetrexed (500 mg per square meter) for non-squamous histology or paclitaxel (200 mg per square meter) for squamous histology. All drugs in the PCT regimens will be administered intravenously every 3 weeks. Cemiplimab 350 mg "flat dose" will be administered intravenously every 3 weeks. Treatment will continue for a maximum of 108 weeks or until progression or unacceptable toxicity.

Comparator: Single-agent cemiplimab. Cemiplimab 350 mg "flat dose" will be administered intravenously every 3 weeks for 108 weeks or until progression or unacceptable toxicity.

Efficacy criteria: The rate of patients experienced HPD or ED will be calculated for both treatment arms.1 HPD is defined as a delta of tumor growth rate (TGR) ≥50% and/or a TGR ratio ≥2. TGR will be computed using RECIST v.1.1 on three consecutive, centrally revised, CT scans (two CT scans before treatment start and one after 7 week ± 5 days from treatment start).

Central review of CT scans will be performed before treatment start and after the first radiological evaluation (before third cycle). RECIST response after the second cycles will be decided according to central review.

ED is defined as tumor-related death within 12 weeks from ICI initiation, in absence of a radiological evaluation performed during ICI.

HPD rate according to definitions proposed by Lo Russo et al., Matos et al.et Saâd-Bouzid et al., will be evaluated as a secondary endpoint.

Efficacy parameters: After the first radiological evaluation performed at 7 weeks ± 5 days from treatment start, subjects will be evaluated by CT scans every 12 weeks ± 28 days according to local investigators' schedule.

CT scans are to be performed until disease progression or until the start of new anticancer treatment, withdrawal of consent, or death, whichever occurs first.

Per RECIST 1.1, the partial and complete response should be confirmed by a repeat tumor imaging assessment not less than 4 weeks from the date the response was first documented.

The enrollment period will last 48 months. The approximate duration of the active study assessments for each patient, including the screening phase, will be 3 months (the time required to confirm HPD occurrence or not). The duration of the active portion of the study will be 48 months, followed by and additional 3 months of follow-up, for a total of 51 months. In both arms, patients will receive treatment for a maximum of 108 weeks or until disease progression or unacceptable toxicity occurs. After the active portion of the study is completed, all patients will be followed for survival.

Terms in these criteria, in plain language(24)

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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

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.

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.

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.
