What Telisotuzumab Vedotin-Tllv does in the body

1 )] , who have received a prior systemic therapy .

Telisotuzumab vedotin-tllv is a c-Met-directed antibody drug conjugate (ADC). The antibody is a humanized IgG1κ directed against c-Met, the cell surface receptor for hepatocyte growth factor. The small molecule, MMAE, is a microtubule-disrupting agent, attached to the antibody via a protease cleavable linker. Following binding to c-Met-expressing cells, telisotuzumab vedotin-tllv undergoes internalization and intracellular cleavage of MMAE.

Why people take it. EMRELIS is indicated for the treatment of adult patients with locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC) with high c-Met protein overexpression [≥50% of tumor cells with strong (3+) staining], as determined by an FDA-approved test [see Dosage and Administration ( 2.1 )] , who have received a prior systemic therapy .

Words this page uses

Four words worth knowing first

Chosen from what this page shows, with each one explained before the word it depends on.

Formulation

A formulation is the exact made-up form a substance comes in.

A picture of it, and where the picture fails

It is like the difference between a whole bean and instant coffee.

Where that stops being true. Coffee tastes different. A formulation can change how much reaches the blood.

What people get wrong. Two products with the same name are assumed to behave the same. They often do not.

The specific composition and physical form of a product, including salt, excipients and release profile.

What we know
RNAWiki holds 1 written-up human studies for this substance, each with the question it asked.
How we know it
Each card names the study, the number of people and what the study set out to measure.
What this does not prove
These summaries were written by a person and have not been signed off as reviewed claims.
Why it matters
A study that failed is as informative as one that worked, and both are here.
What we still do not know
No reviewed claim exists, so no exact population, effect size or interval is published yet.

RNAWiki cannot tell whether a study fits you. It can show who was in it, and where the result stops carrying.

Who was studied

People similar to this profile were included.

  • Locally advanced or metastatic, non-squamous non-small cell lung cancer (NSCLC) with high c-Met protein overexpression [

Who is missing from the studies

RNAWiki cannot tell whether a study fits you. It can show who was in it.

What it would be like to takeRead from sources, not yet reviewed

Why it might seem to do nothing

A real effect and a noticed effect are different things. These are the recorded reasons the two come apart.

It was studied in different people

The people in the studies were not much like the reader.

On this record: Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

A different form was studied

The studied form is not the form on the shelf.

On this record: This record is linked to 1 related forms. Evidence does not carry across all of them.

The evidence may simply be wrong

Small early studies often do not hold up.

On this record: RNAWiki has not yet published a reviewed conclusion for this use.

Other reasons RNAWiki checked and found nothing for (10)
It was studied for a different goal
The studies measured something else entirely. Nothing in this record points to this reason.
There was nothing to correct
Where a level is already normal, topping it up may change nothing. Nothing in this record points to this reason.
Something else had to happen too
In the studies it was paired with training, a diet or another treatment. Nothing in this record points to this reason.
The change is too small to feel
A real change can still sit below what a person notices. Nothing in this record points to this reason.
Day-to-day swing hides it
Sleep, food, stress and time of day move most numbers more than this would. Nothing in this record points to this reason.
Not enough time yet
The studies ran longer than the person has waited. Nothing in this record points to this reason.
It was not taken as studied
Missed days change the result, and studies count them. Nothing in this record points to this reason.
Something else changed at the same time
Two changes at once cannot be told apart afterwards. Nothing in this record points to this reason.
The product may not be what it says
Contents of a sold product are not always what the label states. Nothing in this record points to this reason.
No recorded reason
RNAWiki has nothing stored that would explain it. Nothing in this record points to this reason.

None of these is a reason to take more. Taking more is not a step this page ever suggests.

Nothing found in the sources checked

No harm is recorded against this substance in the sources RNAWiki checked. Finding nothing is not the same as showing there is nothing.

The sources listed were searched and held nothing. That is not the same as nothing existing.

Over a long time. No completed tested study window is recorded, so long-term effects are not established by the registry record.

Groups the studies covered thinly. Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

What is missing or unclearRead from sources, not yet reviewed

What you could measure

This one is decided with a clinician, so this section holds questions to ask rather than a plan to run.

Self-experiment planning is not offered for a prescription or clinician-supervised medicine. The questions below are for a clinician or pharmacist.

Questions worth asking

  • Which of the trials of Telisotuzumab Vedotin-Tllv studied people like me?
  • What was measured, and for how long?
  • Was the result a laboratory value or a health outcome?
  • What would we watch for, and when would we stop?

Tracking can show whether something changed for you. It cannot show what caused it.

RNAWiki records evidence. It does not say whether this substance is right for you.

  • pharmacokinetics
    MMAE is metabolized primarily by CYP3A4.
  • pharmacokinetics
    In Vitro Studies Cytochrome P450 (CYP) Enzymes: MMAE is a substrate and an inhibitor of CYP3A4/5.
  • pharmacokinetics
    Strong CYP3A4 Inducer: MMAE AUC is predicted to decrease by 70% following concomitant administration of EMRELIS with rifampicin (a strong CYP3A inducer).
  • pharmacokinetics
    Strong CYP3A4 Inhibitor: MMAE AUC is predicted to increase by 1.4-fold following concomitant administration of EMRELIS with ketoconazole (a strong CYP3A inhibitor).
  • pharmacokinetics
    Transporter Systems: MMAE is a substrate of P-glycoprotein (P-gp).
