About this study

Official title: Phase I/II Dose Escalation Trial of Rhenium 188-P2045 in Small Cell Lung Cancer and Other Advanced Neuroendocrine Carcinomas as a Single Agent and in Combination With Topotecan

There are two parts to this trial. The first study will evaluate increasing doses of Re188 P2045 in patients with advanced small cell lung cancer that has recurred after initial therapy or in patients with other advanced neuroendocrine cancers that have progressed after therapy.

Re188 P2045 is designed to attach to type 2 somatostatin receptors that are frequently expressed in those cancers and then the radioactivity from Re188 will kill the cancer cell. Only patients who have cancers that can be seen when Tc99 P2045 is administered (also seeks out the SSTR2, but Tc99 images, but does not treat the cells) will be treated.

Therefore, this approach maximizes the possibility that patients will benefit from treatment in that only those who have cancers that have the target will undergo treatment. The primary purpose of this study will be to determine the highest dose of Re188 P2045 that can be safely administered.

The second study will open after the conclusion of the first. Patients will first undergo the scan with Tc99 P2045 and then be treated with topotecan for three days. Topotecan is a standard chemotherapy drug that is approved for second line therapy for small cell and frequently used for other neuroendocrine cancers. Following that, patients will then be re-evaluated with the Tc99 P2045 scan and if it demonstrates that the tumor is positive for SSTR2, then patients will receive Re188 P2045. The goal of this study is to determine the highest dose of Re188 P2045 that can be safely administered after topotecan as well as to determine if topotecan will increase the chance that the tumor will express SSTR2.

Read the detailed description

This trial will be conducted patients with small cell lung cancer and other neuroendocrine cancers. These include extrapulmonary small cell, gastrointestinal carcinoid tumors that arise from pulmonary lesions, and large cell neuroendocrine (NE) tumors.

First, the dose-limiting toxicity (DLT) and maximally tolerated dose (MTD) for Rhenium Re188-P2045 alone will be determined when it is administered as a single dose, at 80, 90, 130, 170, 210 or (up to) 250 mCi/m2.

Subsequently, in the second study Rhenium Re 188-P2045 will be administered at 40, 50, 75, 85 and up to 100 per cent of the MTD determined in the first study, as a single agent or following 3 daily topotecan treatments (at 1.0 or 1.5 mg/m2) in patients with advanced neuroendocrine tumors and SSTR2 expression as determined by Technicium (Tc) Tc99m P2045 scanning.

The overall response and survival rates of patient treated with Rhenium Re188 P2045 when administered as a single dose or following topotecan will be measured.

The change (if any) in SSTR2 expression, as determined by Tc99m P2045 scanning after topotecan administration will also be determined . The correlation of pre-therapy SSTR2 expression (as determined by Tc99m P2045 scan) with overall response and survival rates will be calculated.

Study groupRoleWhat they receive
Topotecan and Rhenium Re 188 P2045ExperimentalIn the phase II portion of this study, patients will be screened using Technicium Tc99m. Eligible, consented patients will receive Topotecan treatment for three days, at doses of either 1.0 mg/m2 or 1.5 mg/m2. They will then receive a single dose of Rhenium Re 188-P2045, at one of the following dosage levels based on the Phase I Maximum Tolerated Dose (MTD): 40% of MTD; 50% of MTD; 75% of MTD; 85% of MTD or 100% of MTD.

What is being measured

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

  1. Determine Maximum Tolerated Dose (MTD)

    To determine, via dose-limiting toxicity (DLT), the maximally tolerated dose (MTD) for Rhenium Re188-P2045 when administered as a single dose in patients with advanced neuroendocrine tumors and SSTR2 expression as determined by Tc99m P2045 scanning.

    Measured: 28 days

Secondary outcomes (4)
  1. Overall Response Rate (ORR)

    To describe the overall response rate (ORR) after treatment with Re188 P2045 when administered either as a single dose (Phase I) or following topotecan (Phase II) in patients with advanced neuroendocrine tumors and SSTR2 expression as determined by Tc99m P2045 scanning.

    Measured: 5 Years

  2. Progression Free Survival (PFS) Rate

    To describe the progression free survival rate (PFS) of survival after treatment with Re188 P2045 when administered as a single dose or following topotecan in patients with advanced neuroendocrine tumors and SSTR2 expression as determined by Tc99m P2045 scanning

    Measured: 5 years

  3. Change in SSTR2 Expression

    To describe the change (if any) in SSTR2 expression, as determined by Tc99m P2045 scanning after topotecan administration.

    Measured: 3 Days

  4. Correlation: Pre-therapy SSTR2 Expression vs. ORR and PFS

    Calculate potential correlation between pre-therapy SSTR2 expression, as determined by Tc99m P2045 imaging, and patient Overall Response Rate (ORR) up to 5 years post treatment. Calculate potential correlation between pre-therapy SSTR2 expression, as determined by Tc99m P2045 imaging, and patient Progression Free Survival (PFS) up to 5 years post treatment.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Rhenium Re 188-P2045 in people with Small Cell Lung Cancer (SCLC) and Neuroendocrine (NE) Tumors, run by University of Maryland, Baltimore 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 17 inclusion and 14 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: withdrawn, as of the sponsor's last update on 17 Oct 2019. 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 combined 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.

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 was withdrawn before enrolling participants, so there are no results.

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?

Determine Maximum Tolerated Dose (MTD) (time frame: 28 days). 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 17 Oct 2019.
