About this study

Official title: REPLATINUM: A Phase 3, Controlled, Open-label, Global Randomized Study of RRx-001 Administered Sequentially With a Platinum Doublet or a Platinum Doublet in Third-Line or Beyond Small Cell Lung Cancer

This Global Phase 3 study aims to find out whether RRx-001 + platinum chemotherapy is more effective than platinum chemotherapy alone in 3rd line or beyond small cell cancer.

Read the detailed description

Small cell cancer (SCC), which mostly arises in the lungs but also in other parts of the body as well such as the prostate and the intestines, is one of the most aggressive forms of cancer; in fact, SCC is so aggressive that in 2012 Congress designated it a recalcitrant or difficult-to-treat cancer, along with pancreatic cancer and glioblastoma or GBM, a primary tumor of the brain, which share the terrible "distinction" of having a 5 year survival rate less than 50%.

One of the main reasons that SCC is so recalcitrant or difficult-to-treat has to do with the development of resistance. Almost all cancers (and SCC is no exception) are treated according to lines of therapy. A line of therapy is a particular course of treatment or treatment regimen. So, in SCC, the first line of treatment is a platinum doublet, with the word doublet meaning two, and consists of the double chemotherapy regimen of cisplatin or carboplatin + etoposide. Most patients initially respond well to the platinum doublet but unavoidably, as a matter of course, resistance to treatment develops and, with that development, a new treatment in second line is started. The same pattern is followed in later lines of therapy: resistance in second line leads to the start of another treatment in 3rd line, and with resistance in 3rd line, which is, unfortunately, just as inevitable, and usually happens even sooner, since the later the line of therapy the more aggressive the tumor, a 4th line treatment is started and so on and so forth until, eventually, no lines of treatment are left. The implicit or unwritten rule in cancer therapy is that once resistance occurs on a particular treatment that same treatment is never reintroduced or restarted.

RRx-001 is a form of immunotherapy that has the potential to overturn this unwritten rule by sensitizing tumors, in other words, by making them more sensitive to the platinum doublet that they received in first line. This is very important because, as previously stated, the platinum doublet is usually the most effective therapy, so it is a benefit to patients if sensitivity to the platinum doublet is restored or increased (even in cases where no response ever occurred) and now they respond as if they were in 1st line rather than in 3rd line or beyond.

In this study, which is called REPLATINUM, because patients will be reintroduced to or restarted on a platinum doublet, there is a 50% chance of receiving either RRx-001 + platinum doublet in Arm 1 or a platinum doublet without RRx-001 in Arm 2. However, patients in arm 2 whose cancer progresses or gets worse (as determined by imaging scans), have the opportunity to "cross-over" to Arm 1 and receive RRx-001 + platinum doublet until such time as their cancer progresses. In this way, all patients, even those on Arm 2, are potentially eligible to be treated with RRx-001.

What is being measured

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

  1. Progression Free Survival (PFS) and Overall Survival (OS)

    To compare the co-primary efficacy endpoints comprising progression free survival (PFS) and overall survival (OS). PFS is defined as the time from randomization until disease progression or all-cause mortality between the two arms. Disease progression is assessed by the blinded independent central review (BICR) via RECIST 1.1, and is the basis for the principal definition of PFS. OS is defined as the time from randomization to all-cause mortality

    Measured: Estimated up to 12 Months

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

    To compare overall response rate (ORR, as assessed by the BICR via RECIST 1.1), between the two arms Duration of response will also be characterized and compared between the two arms

    Measured: Estimated up to 12 Months

Model description
In this study, patients will be randomized to 1 of 2 groups or arms. Patients in Arm 1 will receive the study drug, RRx-001, once a week for 3 weeks followed by up to 4 cycles of platinum doublet (platinum plus etoposide) chemotherapy. Patients with stable disease or better will go on to the Platinum Stacking Phase and will receive RRx-001 once a week for 2 weeks followed by 2 cycles of single agent platinum chemotherapy in a repeating pattern until such time as their cancer gets worse.. Patients in Arm 2 will receive the standard of care platinum doublet (platinum plus etoposide) chemotherapy for up to 4 cycles. . Patients in arm 2 whose cancer gets worse (as determined by imaging scans), may "cross-over" to the Platinum Stacking Phase of Arm 1 (see study schema below).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing RRx-001 + eLOOP Device and Cisplatin/carboplatin plus etoposide in people with Carcinoma, Small Cell Lung, run by EpicentRx, Inc. 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 8 inclusion and 9 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: under way, not looking for participants, as of the sponsor's last update on 31 Oct 2024. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Progression Free Survival (PFS) and Overall Survival (OS) (time frame: Estimated up to 12 Months). 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 Oct 2024.
