A Study of Unesbulin in Participants With Advanced Leiomyosarcoma (LMS)
Not Recruiting
Trial ID: NCT05269355
Purpose
This study will compare the efficacy and safety of unesbulin plus dacarbazine versus placebo
plus dacarbazine in participants with unresectable or metastatic, relapsed or refractory LMS
who have received at least 1 prior line of systemic therapy.
Official Title
A Phase 2/3 Study to Evaluate the Efficacy and Safety of Unesbulin in Unresectable or Metastatic, Relapsed or Refractory Leiomyosarcoma

Eligibility
Key Inclusion Criteria:
- Histological or cytological confirmation of LMS arising at any anatomic site except
bone sarcoma, unresectable or metastatic, relapsed or refractory disease measurable
per RECIST 1.1 criteria
- Disease progression on previous treatment before screening or intolerability to other
oncology treatments
- Participants with liver metastases may be enrolled
- Participants with well-controlled asthma or chronic obstructive pulmonary disease may
be enrolled.
- Toxicity from prior therapies recovered to Grade ≤1 or participant's baseline, except
for alopecia. In addition, endocrinopathies associated with prior immunotherapy-based
treatments that are well controlled on replacement medication are not exclusionary.
- At least 1 prior systemic cytotoxic or targeted therapy regimen for LMS, which may
include but is not limited to single-agent doxorubicin or other anthracycline,
doxorubicin plus ifosfamide, trabectedin, pazopanib, or gemcitabine with or without
docetaxel.
- At least 4 weeks since prior surgery and recovered in the opinion of investigator
Key Exclusion Criteria:
- Received temozolomide or dacarbazine at any time
- Any other systemic anticancer therapy including investigational agents ≤3 weeks before
initiation of study treatment. Additionally, participants may not have received
radiation ≤3 weeks before initiation of study treatment.
- Known intolerance to dacarbazine or one or more of the excipients in unesbulin.
- Co-existing active infection or any co-existing medical condition likely to interfere
with study procedures
- Gastrointestinal disease or other conditions that could affect absorption. Active
peptic ulcer disease, active gastritis, or previous history of gastric perforation
within the last 2 years
- Major surgery, open biopsy, or significant traumatic injury that has not recovered, in
the opinion of the investigator, within 28 days of baseline
- Immunization with a live vaccine within 30 days before starting study drug due to the
risk of serious and life-threatening infections.
- Prior malignancies, other than LMS, that required treatment or have shown evidence of
recurrence (except for non-melanoma skin cancer or adequately treated cervical
carcinoma in situ, prostate cancer in situ or any other low risk malignancy that is
approved by the medical monitor) during the 5 years before initiation.
- Prior or ongoing clinically significant illness, medical or psychiatric condition,
medical history, physical findings, electrocardiogram (ECG) findings, or laboratory
abnormality that, in the investigator's opinion, could affect the safety of the
participant, or alter the absorption, distribution, metabolism, or excretion of the
study drugs, or could impair the assessment of study results.
Note: Other inclusion and exclusion criteria may apply.
