Study summary

This is a placebo-controlled, double blind, comparative study to evaluate the efficacy and safety of KW-2246 as rescue medication at an optimal dose, which is determined by dose titration in treating breakthrough pain episodes in adult cancer patients receiving strong opioid analgesic on a fixed-schedule as well as rescue medication for breakthrough pain.

Inclusion criteria

  • Written
  • Have been treated with opioid analgesic on a fixed-schedule at a stable daily dose
  • Receiving at least 1 but not more than 4 doses of rescue medication per day in average and whose pain is controlled
  • PS =\< 3

Exclusion criteria

Exclusion Criteria:

  • Currently suffered from intolerable opioid-specific adverse reactions due to opioid analgesics
  • Severe respiratory dysfunction
  • Asthma
  • Severe bradyarrhythmia
  • Severe hepatic function disorder
  • Severe renal function disorder
  • Severe psychoneurotic disorder
  • Susceptibility to respiratory depression due to such conditions as increased intracranial pressure, head injury or brain tumor
Terms in these criteria, in plain language(2)

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.
