About this study

This nationally representative randomized survey of US adults will evaluate the effect of using brief statements to communicate multiple different sources of uncertainties about the benefits and harms of new cancer drugs on participants' decisions.

Read the detailed description

Many newer cancer drugs are approved before uncertainties with their underlying clinical trial evidence have been adequately studied, in turn making it difficult to accurately determine the drug's benefits and harms. Prescription drug information rarely communicates these uncertainties. In a nationally representative sample of US adults, this study will evaluate the effect of using brief statements to communicate multiple different sources of uncertainties about the benefits and harms of new cancer drugs on participants' decisions.

In the pre-intervention phase, participants will be given information about a hypothetical new drug approved for the treatment of non-small cell lung cancer. Participants will be asked how likely they would be to take the drug, and how certain they are that the drug will work. Participants will then be randomized with equal allocation to 1 of 5 groups. The control group will receive information about a new cancer drug's benefits and harms; the intervention groups will also be given brief statements about sources of uncertainties with the drug's evidence (1, 2, 3, or 4 sources of uncertainties). The post-intervention questions will re-assess participants' decision making, perceptions of uncertainty, emotions, understanding, and trust.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Statement communicating 1 source of uncertaintyOther

    It is unknown whether patients with non-small cell lung cancer will notice an improvement with Zenova.

  • Statements communicating 2 sources of uncertaintiesOther

    It is unknown whether patients with non-small cell lung cancer will notice an improvement with Zenova.

    Zenova has not been studied in patients similar to Alex (patients with her race and ethnicity). It is unknown whether Zenova will work and what harms it will have for patients like her.

  • Statements communicating 3 sources of uncertaintiesOther

    It is unknown whether patients with non-small cell lung cancer will notice an improvement with Zenova.

    Zenova has not been studied in patients similar to Alex (patients with her race and ethnicity). It is unknown whether Zenova will work and what harms it will have for patients like her.

    Zenova has only been shown to shrink the size of tumors. It is unknown whether Zenova improves how patients feel or how long they live.

  • Statements communicating 4 sources of uncertaintiesOther

    It is unknown whether patients with non-small cell lung cancer will notice an improvement with Zenova.

    Zenova has not been studied in patients similar to Alex (patients with her race and ethnicity). It is unknown whether Zenova will work and what harms it will have for patients like her.

    Zenova has only been shown to shrink the size of tumors. It is unknown whether Zenova improves how patients feel or how long they live.

    Since patients given Zenova were followed for a short time, the longer-term benefits and harms of taking Zenova are unknown.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in decisions

    "Imagine you were Alex and diagnosed with non-small cell lung cancer. How likely are you to take the new drug, Zenova?"

    4-point Likert scale for decision-making: very likely; somewhat likely; somewhat unlikely; very unlikely

    Measured: Immediately prior to and after the intervention.

Secondary outcomes (4)
  1. Change in understanding

    Please answer rate your agreement with the following statements:

    Zenova works better than other treatments for non-small cell lung cancer Zenova's longer-term benefits and harms are well known Zenova has been studied in patients that are similar to Alex (race and ethnicity) Zenova improves how patients feel or how long they live Zenova has a very large benefit for patients with non-small cell lung cancer

    4-point Likert scale for understanding: strongly disagree; somewhat disagree; somewhat agree; strongly agree.

    Measured: Immediately prior to and after the intervention.

  2. Change in perception of uncertainty

    "How certain are you that Zenova will work for Alex?"

    4-point Likert scale for perception of uncertainty: very uncertain; somewhat uncertain; somewhat certain; very certain.

    Measured: Immediately prior to and after the intervention.

  3. Change in emotions

    If you were Alex, how worried would you feel about taking Zenova?

    4-point Likert scale for worry: extremely worried; slightly worried; not very worried; not worried at all.

    Measured: Immediately prior to and after the intervention.

  4. Trust

    To what extent do you think the information about Zenova is trustworthy? 4-point Likert scale: not at all trustworthy; somewhat untrustworthy; somewhat trustworthy; very trustworthy.

    To what extent do you think the FDA, who approved Zenova and produced this information, is trustworthy? 4-point Likert scale: not at all trustworthy; somewhat untrustworthy; somewhat trustworthy; very trustworthy.

    Did learning about these uncertainties with Zenova make you more or less trusting of the FDA? 4-point Likert scale: less trusting, somewhat less trusting, somewhat more trusting, more trusting.

    Measured: Immediately prior to and after the intervention.

Questions about this trial

What is this clinical trial studying?

A study testing Statement communicating 1 source of uncertainty, Statements communicating 2 sources of uncertainties and Statements communicating 3 sources of uncertainties in people with Cancer, run by London School of Economics and Political Science at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in decisions (time frame: Immediately prior to and after the intervention.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07110597, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2026.
