What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to find out whether combining the study drugs rucaparib and nivolumab may be an effective treatment for advanced and/or metastatic LMS, and whether the study treatment works as well as the standard chemotherapy for this type of cancer.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you are on chemotherapy or investigational therapies, you must have completed them at least 3 weeks before starting the study drugs. It's best to discuss your specific medications with the trial team.

How is the drug combination of Rucaparib and Nivolumab unique for treating leiomyosarcoma?

The combination of Rucaparib and Nivolumab is unique for treating leiomyosarcoma because it targets DNA damage repair pathways and enhances the immune response, which are novel approaches compared to traditional chemotherapy options like anthracycline or gemcitabine-based regimens. This combination aims to increase the effectiveness of treatment by addressing the tumor's genetic and immune environment. ^{1 2 3 4 5}

What data supports the effectiveness of the drug combination Rucaparib + Nivolumab for treating leiomyosarcoma?

There is no direct evidence supporting the effectiveness of Rucaparib + Nivolumab for leiomyosarcoma. However, targeting DNA damage repair pathways, which Rucaparib does, is considered promising for advanced leiomyosarcoma. Additionally, while PD-1 inhibitors like Nivolumab have shown limited success alone, combining them with other treatments is being explored for potential benefits. ^{1 2 3 4 6}

Are You a Good Fit for This Trial?

Adults (18+) with advanced or metastatic Leiomyosarcoma who have had 1-3 prior systemic therapies can join this trial. They must not have used PARP inhibitors or PD-1/PD-L1 antibodies before, and should be recovered from previous treatments' side effects. Participants need functioning major organs, measurable disease, and no active infections or significant heart issues. Women of childbearing potential must test negative for pregnancy and agree to contraception.

Inclusion Criteria

My liver function tests are within the required range.

My LMS cannot be removed by surgery and has spread.

I finished any cancer treatments at least 3 weeks ago, and my side effects are mild.

Exclusion Criteria

I do not have any other cancer that needs treatment or could affect this trial.

Subjects expecting to have a child within the projected duration of the trial, starting with the pre-screening or screening visit through 6 months after the last dose of study treatment(s) for women or 7 months for men.

I have a weakened immune system due to conditions like HIV, Hepatitis B/C, or autoimmune diseases.

Timeline for a Trial Participant

1 visit every 4 weeks for nivolumab administration

Follow-up

Participants are monitored for safety and effectiveness after treatment, with re-staging scans every 8 weeks.

What Are the Treatments Tested in This Trial?

Interventions

• Nivolumab
• Rucaparib

Trial Overview The study is testing the combination of Rucaparib (a drug that targets cancer cells) and Nivolumab (an immunotherapy) in patients with Leiomyosarcoma to see if it's more effective than standard chemotherapy. Patients will receive both drugs as part of their treatment regimen.

How Is the Trial Designed?

Group I: Rucaparib in combination with Nivolumab Experimental Treatment 2 Interventions

One treatment cycle will consist of 28 days. Patients will receive rucaparib at 600 mg, orally, twice daily, continuously for 28 days. They will receive 480mg of nivolumab intravenously on day 1 of every four-week cycle. This is the recommended phase II dose of the combination therapy. Re-staging scans will be performed every 8 weeks. Treatment will be repeated until the patient develops progressive disease or unacceptable toxicity or for a maximum duration of 26 cycles as long as patients are receiving benefit from treatment, have not had disease progression, met any criteria for study withdrawal and are tolerating therapy.

Published Research Related to This Trial

In a study of 41 patients with advanced metastatic leiomyosarcoma, combining PD-1 inhibitors with pegylated liposomal doxorubicin (PLD) and dacarbazine (DTIC) resulted in a higher overall response rate (30% vs. 4.8%) compared to chemotherapy alone, indicating some potential for improved initial response.

However, there were no significant differences in progression-free survival (PFS) or overall survival (OS) between the two treatment groups, suggesting that while the combination may enhance response rates, it does not translate into longer survival benefits.

Management of leiomyosarcoma (LMS) is highly individualized, depending on factors like tumor location, whether the disease is localized or metastatic, and the resectability of the tumor.

For patients with recurrent or metastatic LMS, systemic chemotherapy is typically the first-line treatment, with options including anthracycline or gemcitabine regimens, and emerging therapies may be guided by tumor genomics for more personalized treatment approaches.
