简要总结
Background:
Mesothelioma is cancer of the tissue that lines some organs. A new drug, LMB-100, may bind to a protein on mesothelioma tumors and kill cancer cells. But sometimes the body makes antibodies that reduce how well LMB-100 works. Researchers want to see if adding the drug SEL-110 to LMB-100 will prevent these antibodies from forming.
Objective:
To learn how safe and tolerable LMB-100 plus SEL-110 is in people with advanced mesothelioma.
Eligibility:
Adults ages 18 and older who have pleural or peritoneal mesothelioma that has not responded to prior platinum-based therapy
Design:
Participants will be screened with
- Medical history
- Physical exam
- Blood and urine tests
- Sample of tumor tissue. This can be from a previous procedure.
- Scan of the chest, abdomen, and pelvis. Participants will lie on a table in a scanner that takes pictures. A special dye may be injected in a vein.
- Positron emission tomography (fludeoxyglucose positron emission tomography (FDG-PET)) scan. A sugar attached to a chemical that gives off a signal will be injected before the scan.
- Heart function tests
The study will be done in 21-day cycles. Participants will get the study drugs for up to 4 cycles. They will get them through an intravenous (IV) catheter (a tube inserted in a vein, usually in the arm):
- LMB-100 for about 30 minutes on day 1, day 3, and day 5 of each cycle
- SEL-110 for about 1 hour on day 1 of each cycle
Participants will get standard medicines to help prevent side effects.
Participants will repeat some screening tests during each cycle and about 5 weeks after the last dose of study drug.
详细描述
Background:
- LMB-100 and a closely related immunotoxin also targeting mesothelin have been studied in previous Phase 1 clinical studies for mesothelioma and pancreatic cancer.
- Results from these studies showed that the majority of patients formed anti-drug-antibodies (ADAs) that neutralized subsequent injection of the product making it ineffective.
- In a small subset of patients that did not form ADAs to the product, good response and regression of tumors was seen.
- In a different application SEL-110, a biodegradable nanoparticle containing rapamycin, has been shown in clinical trials to prevent the formation of ADAs to an immunogenic enzyme when co-administered. Preclinical data show that SEL-110 also prevents the formation of ADAs to LMB-100.
- This clinical trial will investigate whether SEL-110 when administered with LMB-100 is able to prevent the formation of ADAs and thus allow patients to receive multiple, effective injections of LMB-100.
Objectives:
-The primary objective of the study is to assess the safety and tolerability of LMB-100 in combination with SEL-110.

结局指标
主要结局
Number of Participants With Grade ≥3 Adverse Events Related to Study Drug at Dose Level 140 mcg/kg and 100 mcg/kg
时间窗: Day 85
Here are the grade ≥3 adverse events at each dose level assessed by the Common Terminology Criteria in Adverse Events CTCAE v5.0. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. Grade 3 is Severe or medically significant but not immediately life-threatening;hospitalization or prolongation of hospitalization indicated; disabling;limiting self care ADL (i.e., bathing, dressing and undressing, feeding self, using the toilet, taking medications, and not bedridden. Grade 4 is life-threatening consequences;urgent intervention indicated. Grade 5 is death related to adverse event.
Maximum Tolerated Dose (MTD)
时间窗: Day 21
MTD is defined as the highest tested dose of LMB-100 and SEL-110 at which no more than 1 of 6 subjects experience a dose limiting toxicity. A dose limiting toxicity is defined as any of the following: Grade 4 neutropenia for a minimum duration of 7 days. Grade 4 thrombocytopenia (≤25.0 x 10(9) cells/L), Grade 3 thrombocytopenia associated with bleeding episodes, and Grade 4 anemia. Grade ≥3 non-hematological toxicity with the exception of Alopecia (any grade), Grade 3 nausea and vomiting lasting \> 48 hours despite appropriate treatment, Grade 3 diarrhea lasting for ≤ 2 days with no fever or dehydration, and laboratory values of ≥ grade 3 that are judged not clinically significant by the investigator. Any other drug related toxicity considered significant enough to be qualified as a DLT in the opinion of the principal investigator. Inability to start cycle 2 within 3 weeks after completing cycle 1 due to drug-related adverse events.
次要结局
- Fraction of Participants With Detectable LMB-100 in Blood After Cycle 4(Day 85)
- Number of Participants With Partial Response or Complete Response (PR + CR)(42 days)
- Number of Participants With Serious and Non-Serious Adverse Events(Date treatment consent signed to date off study, approximately one month and 25 days for the 100 mcg/kg Arm/Group, and 9 months and 28 days for the 140 mcg/kg Arm/Group.)
