Δ9-THC (Namisol®) in Chronic Pancreatitis Patients Suffering From Persistent Abdominal Pain
A Phase 2 study testing Tetrahydrocannabinol in people with Pancreatitis, Chronic and Abdominal Pain, run by Radboud University Medical Center at 1 site in Netherlands.
Trial summary
Abdominal pain resulting from chronic pancreatitis (CP) is often recurrent, intense and long-lasting, and is extremely difficult to treat. Medical analgesic therapy is considered as first choice in pain management of CP, resulting in regularly prescription of opioids. Read more about this study

About this study
Official title: Δ9-THC (Namisol®) in Chronic Pancreatitis Patients Suffering From Persistent Abdominal Pain: a Randomized, Double-blinded, Placebo-controlled, Parallel Design
Abdominal pain resulting from chronic pancreatitis (CP) is often recurrent, intense and long-lasting, and is extremely difficult to treat. Medical analgesic therapy is considered as first choice in pain management of CP, resulting in regularly prescription of opioids. The adverse consequences of prolonged opioid use, including addiction, tolerance and opioid induced hyperalgesia, call for an alternative medical treatment. Cannabis has been used to treat pain for many centuries. Delta-9-tetrahydrocannabinol (Δ9-THC), the psychoactive substance of the cannabis plant, has been shown in previous studies to be a promising analgesic. The development of Namisol®, a tablet containing purified Δ9-THC showing an improved pharmacokinetic profile, provides the opportunity to test the analgesic potential of Δ9-THC in favourable conditions. The current study aims to investigate the analgesic efficacy of Namisol® as add-on analgesic during a long-term treatment (52 days) of abdominal pain resulting from CP.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TetrahydrocannabinolDrug
Also called Namisol, Dronabinol
The add-on treatment consists of two phases: a step-up phase (day 1-5: 3 mg TID; day 6-10: 5 mg TID), and a stable dose phase (day 11-52: 8 mg TID). The dosage may be tapered to at least 5 mg TID, when 8 mg is not tolerated.
PlaceboDrug
Identical step-up approach to the Namisol arm.
| Study group | Role | What they receive |
|---|---|---|

The primary outcome measure is defined as the reduction in average VAS pain scores at the end of the study (day 50-52) compared to the pre-treatment level between the Namisol® and placebo group, measured by a Visual Analoge Scale (VAS) in a daily pain diary.
Measured: Baseline versus day 52
Secondary outcomes (7)

QST
Quantitative Sensory Testing; measuring pressure pain thresholds, electrical thresholds, electric wind-up response, and DNIC.
Measured: Baseline versus day 15 and day 52

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Tetrahydrocannabinol in people with Pancreatitis, Chronic and Abdominal Pain, run by Radboud University Medical Center at 1 site in Netherlands.
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 5 inclusion and 22 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 28 Oct 2014. 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 Netherlands. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Average VAS pain (time frame: Baseline versus day 52). 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 NCT01551511, 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 28 Oct 2014.
