Study summary

This trial will study tisotumab vedotin to find out whether it is an effective treatment alone or with other anticancer drugs for certain solid tumors and what side effects (unwanted effects) may occur. There are seven parts to this study.

  • In Part A, participants will receive tisotumab vedotin every 3 weeks (3-week cycles).
  • In Part B, participants will receive tisotumab vedotin on Days 1, 8, and 15 every 4-week cycle.
  • In Part C, participants will receive tisotumab vedotin on Days 1 and 15 of every 4-week cycle.
  • In Part D, participants will be given treatment on Day 1 of every 3-week cycle.
  • Participants in Part D will get tisotumab vedotin with either:

    • Pembrolizumab or,
    • Pembrolizumab and carboplatin, or
    • Pembrolizumab and cisplatin
  • In Part E, participants will receive tisotumab vedotin on Days 1 and 15 of every 4-week cycle.
  • In Part F, participants will receive tisotumab vedotin on Days 1, 15, and 29 of every 6-week cycle. Participants in Part F will get tisotumab vedotin with pembrolizumab.
  • In Part G, participants will receive tisotumab vedotin on Days 1, 15, and 29 of every 6-week cycle. Participants in Part G will get tisotumab vedotin with pembrolizumab and carboplatin.

The objectives of the study have been achieved. Therefore, the study will transition to a long-term extension phase (LTEP).

  • In LTEP, participants still receiving clinical benefit based on the investigator's assessment and remaining on treatment may continue receiving treatment.
  • Participants will still receive tisotumab vedotin with either:

    • Pembrolizumab or,
    • Pembrolizumab and carboplatin, or
    • Pembrolizumab and cisplatin
Read the detailed description

The primary goal of this trial is to assess the activity, safety, and tolerability of tisotumab vedotin for the treatment of selected solid tumors. Patients will be treated with single agent tisotumab vedotin or tisotumab vedotin in combination with other anticancer agents. Patients who meet eligibility criteria will be enrolled into cohorts based on tumor type. Tumor types to be evaluated include colorectal cancer, squamous non-small cell lung cancer (sqNSCLC), exocrine pancreatic adenocarcinoma, and head and neck squamous cell carcinoma (HNSCC).

Terms in these criteria, in plain language(13)

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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

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.

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.

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.

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.

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.

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.

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.
