Brief Summary
Randomized, multicenter, open-label, Phase 3 registration study designed to evaluate the safety and efficacy of milademetan compared to trabectedin in patients with unresectable (i.e., where resection is deemed to cause unacceptable morbidity or mortality) or metastatic DD liposarcoma that progressed on 1 or more prior systemic therapies, including at least 1 anthracycline-based therapy.

Outcome Measures
Primary Outcomes (1)
Compare Progression-free Survival (PFS) as Determined by Blinded Independent Central Review (BICR) Between the Milademetan Treatment Arm and Trabectedin Control Arm
PFS is defined as the time from randomization to the earliest date of the first objective documentation of radiographic disease progression, or death due to any cause. Disease progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
from the randomization date to date of documented progression or death, up to 13 months
Secondary Outcomes (5)
Overall Survival (OS)
From randomization date to death. The result is based on primary analysis data cut.
Disease Control Rate (DCR)
From the randomization date to first CR, PR or SD >= 16 weeks or the primary study completion date; up to 26.6 months.
Objective Response Rate (ORR)
From randomization date to the first confirmed complete or partial response, or study completion date; up to 26.6 months.
PFS by Investigator Assessments
disease progression or death
Number of Participants With Treatment-emergent Adverse Events Until Approximately 30 Days After the Last Study Drug
From first dose date to 30 days after the last dose date or the primary study completion date whichever came first; up to 26.6 months.
Study Arms (2)
RAIN-32 (Milademetan)
EXPERIMENTAL260 mg once daily orally on Days 1 to 3 and Days 15 to 17 of each 28-day cycle.
Trabectedin
ACTIVE COMPARATOR1.5 mg/m2 body surface area as a 24-hour IV infusion, every 3 weeks.
Interventions
260 mg once daily orally on Days 1 to 3 and Days 15 to 17 of each 28-day cycle
1.5 mg/m2 body surface area as a 24-hour IV infusion, every 3 weeks
Eligibility Criteria
You may qualify if:
- Histologically confirmed DD liposarcoma, with or without a WD component (WD/DD liposarcoma). Note: Patient must be willing to provide an archival tumor tissue sample that is ≤ 3 years old and of adequate quality or willing to provide a fresh pretreatment biopsy sample
- Advanced unresectable (i.e., where resection is deemed to cause unacceptable morbidity or mortality) and/or metastatic WD/DD liposarcoma
- Measurable tumor lesion(s) in accordance with RECIST version 1.1
- Received 1 or more systemic cancer therapy regimens, including at least 1 anthracycline-based regimen, and had radiographic progressive disease (per RECIST version 1.1) within 6 months before the Screening Visit
- Resolution of any clinically relevant toxic effects of prior chemotherapy, surgery, radiotherapy, or hormonal therapy
- ECOG performance status of 0 or 1
- Adequate bone marrow function:
- Platelet count ≥ 100 × 10\^9/L
- Hemoglobin ≥ 9.0 g/dL
- Absolute neutrophil count ≥ 1.5 × 10\^9/L
- Adequate hepatic function:
- Alanine aminotransferase and aspartate aminotransferase ≤ 3 × upper limit of normal (ULN) if no liver metastases are present; ≤ 5 × ULN if liver metastases are present
- Total bilirubin ≤ 1.5 × ULN, or ≤ 3 x ULN in the setting of Gilbert's disease
You may not qualify if:
- Prior treatment with any mouse double minute 2 (MDM2) inhibitor or trabectedin
- Other primary malignancies that have required systemic antineoplastic treatment within the previous 2 years, except for localized cancers that have apparently been cured
- Gastrointestinal conditions that could affect the absorption of milademetan, in the opinion of the Investigator
- Uncontrolled infection within the last 7 days requiring IV antibiotics, antivirals, or antifungals
- Known HIV infection or active Hepatitis B or C
- Untreated brain metastases. Note: Patients who require steroids for brain metastases must be on a stable or tapering dose of corticosteroids for at least 2 weeks before randomization. If applicable, patients must complete stereotactic radiosurgery 7 days before and whole brain radiotherapy 21 days before their first dose of study drug.
- Investigational therapy administered within the 28 days or 5 half lives:
- Cytochrome P450 3A4 isozyme strong inhibitor: 5 elimination half-lives
- CYP3A strong or moderate inducers: 4 weeks
- Systemic anticancer therapy or investigational therapy 3 weeks or 5 half-lives,
- Immunotherapy with checkpoint inhibitor: 4 weeks
- Curative-intent radiation therapy ≤ 4 weeks or palliative radiation therapy,
- Uncontrolled or significant cardiovascular disease:
- QTcF at rest, where the mean QTcF interval is \> 480 milliseconds
- Myocardial infarction within 6 months
- +3 more criteria
