Study summary

The primary purpose of this study is to compare the progression-free survival (PFS) in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring human epidermal growth factor receptor 2 (HER2) exon 20 mutations when treated with poziotinib versus docetaxel.

Read the detailed description

This is a Phase 3, active-controlled, multicenter study to compare the efficacy and safety/tolerability of poziotinib versus docetaxel in previously treated participants with locally advanced or metastatic NSCLC harboring HER2 exon 20 mutations.

Participants will be randomized in a 2:1 ratio to:

  • Arm A: Poziotinib 8 milligrams (mg), twice daily (BID) or
  • Arm B: Docetaxel 75 milligrams per meter square (mg/m\^2)

The Screening Period lasts up to 21 days prior to Cycle 1, Day 1 (C1D1). Participants will be treated in 21-day cycles or until disease progression, death, intolerable adverse events (AEs), initiation of non-protocol anti-cancer treatment, or other protocol-specified reasons.

Terms in these criteria, in plain language(9)

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.

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.

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.

HER2

HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.

In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.

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.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

What researchers measure

Primary outcomes

  1. Progression Free Survival (PFS)

    PFS is defined as the time (in months) from the start of the study treatment to the date of first documented disease progression by central radiographic evaluation per the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v.1.1) or death due to any cause, whichever occurs first.

    Time frame: Up to approximately 5 years

Secondary outcomes

  1. Overall survival (OS)

    OS is defined as the time (in months) from the start of study treatment to the date of death due to any cause.

    Time frame: Up to approximately 5 years

  2. Objective Response Rate (ORR)

    ORR is defined as the proportion of participants who achieve at least one complete response (CR) or partial response (PR) by the central radiographic evaluation as per the RECIST v.1.1 criteria, before disease progression. Per RECIST v.1.1 for solid tumors, CR is defined as disappearance of all tumor lesions (TLs) and disappearance or reduction of all pathological lymph nodes \<10mm (short axis). PR is ≥30% decrease in sum of diameters (SOD) from Baseline.

    Time frame: Up to approximately 5 years

  3. Disease Control Rate (DCR)

    DCR is defined as the proportion of participants who achieve at least one CR, PR, stable disease (SD), or non-CR/non-progressive disease (PD), by the central radiographic evaluation per the RECIST v.1.1 criteria, before disease progression. Per RECIST v.1.1 for solid tumors, CR is defined as disappearance of all tumor lesions (TLs) and disappearance or reduction of all pathological lymph nodes \<10mm (short axis). PR is ≥30% decrease in sum of diameters (SOD) from Baseline, and non PD is ≥20% increase in SOD from previous smallest SOD on study, and an absolute increase of ≥5mm). SD is SOD change neither sufficient for PR nor sufficient for PD.

    Time frame: Up to approximately 5 years
