(14). (Response to a specific treatment has occurred if after two CA-125 samples there has been a 50% decrease, confirmed by a fourth sample (50% response), or a serial decrease over three samples of greater than 75% (75% response). The final sample has to be at least 28 days after the previous sample.)

- Patients must sign an informed consent.
- Patients should have adequate bone marrow function defined by an absolute peripheral granulocyte count of > 1,500 or cells/mm3 and platelet count >100,000/mm3 and absence of a regular red blood cell transfusion requirement.
- Patients should have adequate hepatic function with a total bilirubin < 2 mg/dl and SGOT or SGPT < two times the upper limit of normal, and adequate renal function as defined by a serum creatinine < 1.5 x upper limit of normal.

About this study
Official title: Clinical Benefit of Topoisomerase Downregulation: A Phase I Pilot Study
1.1 To determine the regulation of topoisomerase I and II following alternating prolonged exposure to topotecan and etoposide (VP-16)
1.2 To determine the time to progression and the objective response rate of this treatment in patients with incurable ovarian cancer.
Read the detailed description
The rationale to study the downregulation of topoisomerase enzyme in ovarian cancer in relationship to the cell cycle distribution of the cancer cells after a prolonged continuous exposure to topo I and II poisons is to better understand the relationship between cell cycle and topo poisoning, which may lead to better clinical trial designs.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Topotecan and VP16Drug
Course 1A: On day 1 treatment will start with a continuous infusion of TPT at 0.4 mg/m2/day for 21 days. A pump will be used to deliver the TPT. The bag in the pump will be replaced every week for sterility precautions.
Course 1B: On day 28, if ANC is >1,500 and platelets > 100,000, VP-16 will be administered orally at 50 mg/day for 14 days.
What is being measured
The primary outcome is the main question the study is designed to answer.
To determine the regulation of topoisomerase I and II following alternating prolonged exposure to topotecan and etoposide (VP-16)
Measured: 3 years
Secondary outcomes (1)
To determine the time to progression and the objective response rate of this treatment in patients with incurable ovarian cancer
Measured: 3 years

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Topotecan and VP16 in people with Ovarian Cancer, run by New Mexico Cancer Research Alliance at 1 site 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 6 inclusion and 4 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 7 Sep 2011. 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 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
To determine the regulation of topoisomerase I and II following alternating prolonged exposure to topotecan and etoposide (VP-16) (time frame: 3 years). 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 7 Sep 2011; AzTrials last refreshed its copy on 8 Nov 2026.
