What You Need to Know Before You Apply

What is the purpose of this trial?

To compare Overall Survival (OS) for INT230-6 vs United States (US) Standard of Care (SOC) in participants with unresectable or metastatic liposarcoma, undifferentiated pleomorphic sarcoma or leiomyosarcoma who have disease progression prior to study enrollment following no more than 2 standard therapies, which must have included an anthracycline-based regimen, unless contraindicated, and then a maximum of 1 additional regimen.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot be on certain medications like strong CYP3A4 inhibitors or those that prolong the QT interval. It's best to discuss your current medications with the trial team.

Are You a Good Fit for This Trial?

Adults with specific types of Soft Tissue Sarcoma (liposarcoma, leiomyosarcoma, or undifferentiated pleomorphic sarcoma) that can't be surgically removed or has spread. They should have tried an anthracycline-based treatment and up to one more therapy without success. Their tumors must be visible on scans and they need to be physically well enough for daily activities.

Inclusion Criteria

My sarcoma is one of the specified types and cannot be surgically removed.

I have had 1-2 treatments for soft tissue sarcoma and my condition worsened after.

My cancer can be measured by standard health scans.

What Are the Treatments Tested in This Trial?

Interventions

• INT230-6

Trial Overview The trial is testing INT230-6 against the US Standard of Care treatments like Eribulin, Trabectedin, and Pazopanib in patients whose sarcomas have worsened after previous treatments. The main goal is to see if INT230-6 helps patients live longer compared to standard options.

How Is the Trial Designed?

Group I: INT230-6 Monotherapy Experimental Treatment 1 Intervention

INT230-6 administered intratumorally. Participants will be dosed every 2 weeks (± 2 days) for up to a total of 5 treatment sessions (e.g., Days 1, 15, 29, 43 and 57). Once the participant has completed the treatment phase, they will continue into a 22-month maintenance phase, where investigators may inject new lesions or previously injected lesions with up to 175 mL of INT230-6 every 12 weeks (Q12W) ± 14 days. Dose volume in a session is dependent on the participants presenting tumor burden.

Group II: US Standard of Care Active Control 3 Interventions

Participants in this arm may receive any of the following depending on soft tissue sarcoma (STS) subtype and PI preference: * Pazopanib: 800 mg PO every day until clinical deterioration or disease progression * Trabectedin: 1.5 mg/m2 body surface area as 24-hour IV infusion every 3 weeks until clinical deterioration or disease progression * Eribulin: Non- European Union (EU) sites: 1.4 mg/m2 eribulin mesylate body surface area IV on Days 1 and 8 every 3 weeks until clinical deterioration or disease progression EU sites: 1.23 mg/m2 (free base) body surface area IV on Days 1 and 8 every 3 weeks until clinical deterioration or disease progression
