What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called lorigerlimab for individuals with ovarian cancer that no longer responds to standard platinum-based chemotherapy or for those with clear cell gynecologic cancer. The trial aims to evaluate the effectiveness and safety of lorigerlimab for these conditions. Participants will receive the treatment through an IV every 21 days, with doctors closely monitoring for side effects and changes in tumor size. This trial may suit individuals with ovarian or clear cell gynecologic cancer who have not had success with previous treatments and are in generally good physical condition. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that lorigerlimab is likely to be safe for humans?

Research has shown that lorigerlimab effectively fights tumors and is generally safe. This treatment enhances the body's immune response against cancer by targeting two proteins that typically allow cancer to evade detection.

Earlier research indicated that most patients tolerated lorigerlimab well, experiencing no severe side effects. However, some side effects may occur, and healthcare providers closely monitor them.

Overall, evidence suggests that lorigerlimab is safe, with manageable side effects for most patients. Prospective trial participants should discuss any concerns with the study team. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for ovarian cancer?

Unlike the standard treatments for ovarian cancer, which often include chemotherapy and targeted therapies, Lorigerlimab is a novel monoclonal antibody. Researchers are excited about Lorigerlimab because it targets specific proteins on cancer cells more precisely, potentially leading to fewer side effects compared to traditional chemotherapy. Additionally, Lorigerlimab's unique mechanism of action might enhance the immune system's ability to recognize and attack ovarian cancer cells, offering a promising new approach for patients.

What evidence suggests that lorigerlimab might be an effective treatment for ovarian cancer?

Research has shown that lorigerlimab could be a promising treatment for certain cancers. Lorigerlimab is a special type of protein that targets two cancer-related proteins, PD-1 and CTLA-4, to help the immune system fight cancer cells. In studies on other cancers, lorigerlimab slowed disease progression. This trial will evaluate lorigerlimab in two separate cohorts: one for platinum-resistant ovarian cancer and another for clear cell gynecologic cancer. Researchers aim to see if it offers similar benefits in these specific cancers. Early research on different cancers suggests that lorigerlimab might help patients who have already tried other treatments. While more information is needed specifically for ovarian and gynecologic cancers, its mechanism supports its potential effectiveness. ^{1 5 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults with certain advanced solid tumors, including ovarian, endometrial, cervical, vaginal, vulvar and uterine cancers that are resistant to platinum-based chemotherapy. They must have had a limited number of prior treatments and not be pregnant or breastfeeding. Participants need measurable disease by RECIST v1.1 criteria and acceptable health status.

Inclusion Criteria

Participants must not be pregnant, planning to be pregnant, or breastfeeding

Participants must have at least one lesion that meets the definition of measurable disease by RECIST v1.1

Participants of childbearing potential must agree to use highly effective methods of birth control

Exclusion Criteria

Any underlying medical or psychiatric condition impairing participant's ability to receive, tolerate, or comply with the planned treatment or study procedures

I have had a stem cell, tissue, or organ transplant in the past.

I have been treated with a checkpoint inhibitor before.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive lorigerlimab by intravenous (IV) infusion on Day 1 of every 21-day treatment cycle

Until progression of cancer or unacceptable side effects

1 visit every 21 days (in-person)

Monitoring

Participants are monitored for side effects and tumor status is checked approximately every 9 weeks for the first year, then every 12 weeks

Throughout treatment

Follow-up

Participants have a safety follow-up performed within 30 days after treatment discontinuation

30 days

Survival Follow-up

What Are the Treatments Tested in This Trial?

Interventions

• Lorigerlimab

Trial Overview

The study tests Lorigerlimab in patients with specific gynecologic cancers resistant to standard treatments. It's an open-label trial where all participants receive the drug via IV every three weeks until their cancer progresses or side effects become too severe.

How Is the Trial Designed?

Group I: PROC Cohort Experimental Treatment 1 Intervention

Lorigerlimab IV every 21 days

Group II: CCGC Cohort Experimental Treatment 1 Intervention

Lorigerlimab IV every 21 days

Published Research Related to This Trial

In a phase Ib trial involving 26 patients with advanced PD-L1-positive ovarian cancer, pembrolizumab demonstrated a confirmed objective response rate of 11.5%, indicating some level of antitumor activity, with 1 complete response and 2 partial responses observed.

The treatment was generally well-tolerated, with 73.1% of patients experiencing treatment-related adverse events, but no deaths or treatment discontinuations due to these events, suggesting that pembrolizumab has a manageable safety profile.

Immune checkpoint inhibitors, which target specific proteins like CTLA-4 and PD-1, have significantly improved survival rates for patients with advanced solid tumors, including ovarian cancer.

The report emphasizes the need for early recognition and management of immune-related adverse events, which differ from those seen with traditional chemotherapy, highlighting the unique challenges of immunotherapy in treating gynecologic cancers.

In a study of 44 women with recurrent ovarian cancer treated with immune checkpoint inhibitors, the overall response rate was 14.2%, with a notable correlation between platinum sensitivity and response in high-grade serous ovarian cancer (HGSOC) patients.

Severe immune-related adverse events (irAEs) occurred in 47.7% of patients, with elevated hepatic or pancreatic enzymes being the most common, and a higher number of gene mutations appeared to protect against these specific adverse effects.
