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
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Participant must have a histological diagnosis of high grade serous ovarian cancer, which includes fallopian tube and primary peritoneal cancer, that is metastatic or recurrent.
  • Participant must have platinum-sensitive recurrent disease, defined as having achieved either a partial or complete response to 4 or more cycles in their penultimate platinum- containing regimen and their disease progressing more than 6 months after completion of the last dose of platinum containing therapy in the penultimate regimen.
  • Participant must have had 4 to 8 cycles of platinum-based chemotherapy in 2nd to 4th line setting in their most recent treatment regimen as defined below:
  • Platinum-based chemotherapy regimens allowed immediately preceding enrollment to the study: carboplatin or cisplatin ±: paclitaxel, docetaxel, pegylated liposomal doxorubicin or gemcitabine.
  • Participant must receive first study treatment infusion between 4 and 12 weeks after completing final dose of platinum in the most recent platinum-based regimen.
  • Participant must have had as their best response to last line of treatment one of the following: No Evidence of Disease (NED); Complete Response (CR); Partial Response (PR); OR Stable Disease (SD)
  • Participants with NED, CR, or PR as their best response to most recent line of treatment and who have not received treatment with a prior PARP inhibitor must have definitive BRCA1 and BRCA2 testing results that demonstrate no evidence of a deleterious BRCA1 or BRCA2 mutation. Somatic BRCA mutation testing is required for participants who are classified as not having a deleterious mutation by germline testing alone.
  • Participant must provide either a tumor tissue block or fresh cut slides for measurement of NaPi2b expression by a central laboratory. If sufficient archival tumor tissue is not available, then a tumor tissue block or slides must be obtained from a fresh biopsy and provided to the central laboratory. Confirmation of a NaPi2b-H/positive tumor by the central laboratory is required prior to randomization.

Who cannot join

  • Participant has received prior treatment with mirvetuximab soravtansine or another ADC containing an auristatin or maytansinoid payload.
  • Participant has received bevacizumab in combination with last platinum-based regiment or plans to receive maintenance therapy outside the study intervention.

  • Participant has ascites or pleural effusion managed with therapeutic paracentesis or thoracentesis within 28 days prior to signing the principal study consent form.
  • Participant has history of cirrhosis, hepatic fibrosis, esophageal or gastric varices, or other clinically significant liver disease. Testing beyond laboratory studies otherwise defined in the eligibility criteria, to diagnose potentially clinically significant liver disease based on risk factors such as hepatic steatosis or history of excessive alcohol intake, will be based on clinical judgement of the investigator.
  • Participant has history of or suspected pneumonitis or interstitial lung disease.
  • Participant has untreated CNS metastases (including new and progressive brain metastases), history of leptomeningeal metastasis, or carcinomatous meningitis.

About this study

Official title: A Phase 3, Randomized, Double-blind, Placebo-controlled, Multicenter Study of Upifitamab Rilsodotin (XMT-1536) as Post-Platinum Maintenance Therapy for Participants With Recurrent, Platinum-Sensitive, Ovarian Cancer (UP-NEXT)

UP-NEXT is a double-blind, randomized, placebo-controlled study of the antibody-drug conjugate (ADC) XMT-1536 (upifitamab rilsodotin) administered as an intravenous infusion once every four weeks in patients with recurrent, platinum-sensitive high-grade serous ovarian cancer (HGSOC), including fallopian tube and primary peritoneal cancer, expressing high levels of NaPi2b.

Read the detailed description

This is a multi-center randomized study of XMT-1536 (upifitamab rilsodotin) in patients with tumors expressing high levels of NaPi2b, focusing on patients with recurrent, platinum-sensitive high-grade serous ovarian cancer (HGSOC) including fallopian tube and primary peritoneal cancer. The randomized study design is a double-blind, placebo-controlled study, with a randomization ratio of 2:1. All adverse events will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria version (CTCAE v5.0). Participants must have had 4 to 8 cycles of platinum-based chemotherapy in their most recent treatment regimen, including carboplatin or cisplatin ± paclitaxel, docetaxel, pegylated liposomal doxorubicin or gemcitabine in the 2nd-4th line setting for the treatment of platinum-sensitive recurrent disease, with no evidence of disease (NED)/complete response (CR)/partial response (PR)/ or stable disease (SD) as best response.

What is being measured

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

  1. Progression-free survival (PFS) assessed by Blinded Independent Central Review (BICR) using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    PFS is defined as the time from randomization to the earliest date of progressive disease as assessed by BICR per RECIST Version 1.1 or death due to any cause.

    Measured: Up to 12 months after the last dose for the last participant.

Secondary outcomes (6)
  1. Overall Survival (OS)

    OS is defined as the time from randomization to the date of death due to any cause.

    Measured: Up to an average of 4 years. Follow up assessments for survival data will continue every 90 days following completion of treatment.

  2. Progression-free Survival (PFS) as assessed by Investigator using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    PFS is defined as the time from randomization to the earliest date of progressive disease as assessed by Investigator per RECIST Version 1.1 or death due to any cause.

    Measured: Up to 12 months after the last dose for the last participant.

  3. Adverse events (AEs) based on NCI CTCAE Version 5.0

    Incidence and toxicity grade of AEs.

    Measured: Up to 60 days past last dose

  4. Changes in Eastern Cooperative Oncology Group (ECOG) performance status

    Assessment of ECOG performance status using ECOG performance scale.

    Measured: Up to 60 days past last dose.

  5. Objective Response Rate (ORR) as assessed by Investigator using RECIST Version 1.1

    ORR is the percentage of patients achieving a confirmed complete response (CR) or partial response (PR) as assessed by Investigator per RECIST Version 1.1.

    Measured: Up to 12 months after the last dose for the last participant.

  6. Number of participants using concomitant medications

    Assessment of concomitant medication usage.

    Measured: Up to 60 days past last dose.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Upifitimab rilsodotin in people with High Grade Serous Ovarian Cancer and Fallopian Tube Cancer, run by Mersana Therapeutics at 30 sites in 3 countries.

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 7 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: stopped early, as of the sponsor's last update on 26 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 30 sites in United States, Australia, Canada. 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 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?

The study was stopped early (reason given: Study Terminated by Sponsor). Results are not available in the source record.

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) assessed by Blinded Independent Central Review (BICR) using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (time frame: Up to 12 months after the last dose for the last participant.). 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 26 Oct 2023.
