Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Subject was enrolled in Protocol No. CP-106 and successfully completed 12 treatment cycles.
- Subject must have been classified as a responder at the time of completion of Protocol No. CP-106 [i.e., SD or better per RECIST Committee criteria or stable symptoms or better (defined as an average daily frequency of bowel movements, flushing episodes and/or wheezing episodes that is the same as or less than the average daily frequency of bowel movements, flushing episodes and/or wheezing episodes recorded during the 14-day screening period prior to enrollment in Protocol No. CP-106)].
- Subject must understand and voluntarily sign the informed consent document.
- Subject must have adequate organ function defined as follows: Absolute granulocyte count (AGC) >1,500/mm3, hemoglobin >8 g/dl, platelets >100,000/mm3, serum bilirubin <1.5 x upper limit of normal (ULN), serum creatinine <1.5 mg/dL, SGOT ≤Grade 1 per NCI CTCAE, SGPT ≤Grade 1 per NCI CTCAE.
- Women of child bearing potential (WCBP) must have a negative serum or urine pregnancy test.

- Any condition which, in the opinion of the Investigator, places the subject at unacceptable risk if he/she were to participate in the study.
- As atiprimod is a potent inhibitor of CYP2D6, the use of drugs that are substrates of CYP2D6 (e.g. beta blockers, antidepressants, and antipsychotic;) will not be allowed while on study.

About this study
Official title: A Phase II Open-Label Extension Study of the Safety and Efficacy of Atiprimod Treatment for Patients With Low to Intermediate Grade Neuroendocrine Carcinoma
This study is an extension study to the Callisto protocol CP-106. Subjects must have completed all 12 treatment cycles of CP-106 without disease progression as per RECIST criteria,to be eligible to to be enrolled in this study. This study will evaluate the safety and efficacy of atiprimod treatment in patients with low to intermediate grade neuroendocrine carcinoma who have metastatic or unresectable local-regional cancer and who have either symptoms (diarrhea, flushing and/or wheezing) despite standard therapy (octreotide) or progression of neuroendocrine tumor(s).
Read the detailed description
For carcinoid, despite the many cytotoxic chemotherapy trials that have been conducted, no regimen has demonstrated a response rate of more than 20% using the criterion of a 50% reduction of bidimensionally measurable disease. In the more recently reported ECOG phase III study of chemotherapy in carcinoid tumors (E1281), patients were randomly assigned to treatment with 5-fluorouracil (5FU) plus doxorubicin or 5FU plus streptozocin. The median progression free survival durations were disappointing. They were 4.5 months in the 5FU plus doxorubicin arm and 5.3 months in the 5FU plus streptozocin arm. Overall survival durations recorded in the trial were also suboptimal at 15 and 24 months respectively. There is no clear survival benefit for cytotoxic chemotherapy.
This is a phase II, multi-center, open-label extension study of the safety and efficacy of atiprimod treatment in patients with low to intermediate grade neuroendocrine carcinoma who have metastatic or unresectable local-regional cancer and who have either symptoms (diarrhea, flushing and/or wheezing) despite standard therapy (octreotide) or progression of neuroendocrine tumor(s) (defined as the appearance of one or more new lesions or a 20% increase in the sum of the longest diameter of target lesions during the 6 months prior to enrollment in CP-106). Atiprimod will be administered orally as a single daily dose of 60 mg/day for 14 days, followed by a 14-day treatment-free period (i.e., 1 treatment cycle = 28 days).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Atiprimod in people with Neuroendocrine Carcinoma, run by Callisto Pharmaceuticals at 2 sites in United States.
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 6 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 31 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. 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. 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?
Reduction of symptoms (diarrhea, flushing and/or wheezing) (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 31 Aug 2011; AzTrials last refreshed its copy on 8 Nov 2026.
