Study Details

Study Description

Brief Summary

This study seeks to determine if addition of trabectedin (T) to combination doxorubicin (D) and olaratumab (O), is feasible and tolerable with antitumor activity in metastatic or recurrent Leiomyosarcomas (LMS) patients who have limited therapeutic options.

Condition or Disease	Intervention/Treatment	Phase
Leiomyosarcoma	Drug: Trabectedin Drug: Doxorubicin Drug: Olaratumab	Phase 1

Detailed Description

This is a traditional 3+3 phase I trial design to identify the recommended phase II dose (RP2D) of Trabectedin [T] that can be used in combination with Doxorubicin [D] and Olaratumab [O] for the treatment of patients with advanced stage or recurrent LMS.

Patients will be treated at an assigned dose level of combination therapy per dose escalation design.

Outcome Measures

Primary Outcome Measures

Recommended Phase 2 Dose (RP2D) of Trabectedin in Combination with Doxorubucin and Olaratumab [About 21 days, one cycle of protocol therapy]
Determination of the recommended phase 2 dose (RP2D) of Trabectedin [T] to be used in combination with Doxorubicin [D] and Olaratumab [O] for the treatment of patients with metastatic or recurrent LMS. Patients will be treated at one of 4-6 dose levels according to the standard dose escalation/de-escalation scheme. In accordance with this scheme, the RP2D of TDO will be established as the highest dose level tested for which no more than 2 out of 12 patients experiences dose-limiting toxicity (DLT).

Secondary Outcome Measures

Toxicity in Study Participants [Up to 8 months]
Determination of the safety, tolerability, and toxicity profile of administering TDO in metastatic or recurrent LMS patients, including assessment of dose-limiting toxicities (DLTs).
Clinical Benefit Rate in Study Participants [From Baseline to End of Treatment, up to 8 months]
Clinical benefit rate (CBR), as defined by best response, (Complete Response (CR), Partial Response (PR) or Stable Disease (SD)) will be assessed using Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.1.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Histologically confirmed metastatic, advanced, or recurrent, LMS. Note: Patients should have tissue, either archival or fresh biopsy, submitted for pathologic review to confirm diagnosis of LMS. For patients with recurrent disease with disease free interval greater than six months, a fresh biopsy must be obtained.
All patients with recurrent or metastatic LMS deemed unresectable must have measurable disease as defined by RECIST 1.1.

All patients with advanced LMS may be enrolled after an initial cytoreductive surgery if there is measurable disease as defined by RECIST 1.1.

Life expectancy greater than 3 months.
Male or female, age ≥18 years
Eastern Cooperative Oncology Group (ECOG) performance status 0, 1.
Resolution of clinically significant toxic effects of prior surgery, radiotherapy or systemic anticancer therapy.
Patients must not have received prior doxorubicin chemotherapy; only 1 prior chemotherapy line allowable and must be discontinued at least 4 weeks prior to first day of study treatment.
Patients should be free of active infections requiring antibiotics (with exception of urinary tract infection).
Patients must have adequate organ and marrow function as defined below: Absolute neutrophil count (ANC) ≥1,500 cells/mm³

Platelet count ≥100,000/mm³
Hemoglobin ≥9.0g/dL
Total bilirubin <1.0 upper limit of normal (ULN)
Alkaline phosphatase of non-osseous origin ≤ 2.5 x ULN
Aminotransferase (AST and ALT) ≤ 2.5 x ULN
Creatinine phosphokinase (CPK) ≤ 2.5 x ULN
Isotope Dilution Mass Spectrometry (IDMS) creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 40 mL/min
Albumin ≤ 3 g/dL*
*Hypoalbuminemia < 3 g/dL should be considered carefully but in and of itself, not exclusionary.

Women of child-bearing potential (WOCBP) must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation until 3 months for women and 5 months for men after completion of study drug administration. WOCBP must have a negative serum or urine test at time of enrollment. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study therapy, and 5 months after completion of study drug administration.
Patients must have adequate cardiac function (ejection fraction ≥ 45%) to receive therapy.
Ability to understand the investigational nature, potential risks and benefits of the research study and to provide valid written informed consent.
