OTL38 for Intra-operative Imaging of Folate Receptor Positive Ovarian Cancer

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03180307
Recruitment Status : Completed
First Posted : June 8, 2017

Brief Summary:
This is a phase 3, randomized, multi-center, single dose, open label, pivotal study in patients diagnosed with, or with high clinical suspicion of, ovarian cancer scheduled to undergo primary surgical cytoreduction, interval debulking, or recurrent ovarian cancer surgery.

Condition or disease Intervention/treatment Phase
Ovarian Cancer Drug: OTL38 Device: near infrared imaging Phase 3

Detailed Description:
The Phase 3 study is to confirm the efficacy of OTL38 in combination with fluorescent light to detect additional Folate Receptor-positive (FR+) ovarian cancer lesions not detected by palpation and visualization under normal light in patients with FR+ ovarian cancer scheduled to undergo primary surgical cytoreduction, interval debulking, or recurrent ovarian cancer surgery

Actual Enrollment : 178 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Other
Official Title: A Phase 3, Randomized, Single Dose, Open-Label Study to Investigate the Safety and Efficacy of OTL38 Injection (OTL38) for Intra-operative Imaging of Folate Receptor Positive Ovarian Cancer
Actual Study Start Date : January 26, 2018
Actual Primary Completion Date : April 16, 2020
Actual Study Completion Date : October 16, 2020

Arm Intervention/treatment
Sham Comparator: no fluorescent imaging
Patient injected with OTL38, but does not undergo fluorescent imaging
Drug: OTL38
0.025 mg/kg of OTL38 in 250ml D5W infused intravenously over 60 minutes
Other Name: OTL38 for Injection

Experimental: near infrared imaging arm
Patient injected with OTL38 and undergoes near infrared imaging
Drug: OTL38
0.025 mg/kg of OTL38 in 250ml D5W infused intravenously over 60 minutes
Other Name: OTL38 for Injection

Device: near infrared imaging
Infrared imaging used to excite OTL38 for fluorecence
Other Name: Near IR imaging

Primary Outcome Measures :
  1. Efficacy patient level [ Time Frame: 30 days ]
    • Proportion of patients with at least one evaluable FR+ ovarian cancer lesion confirmed by central pathology (Standard of truth) that was detected using the combination of OTL38 and fluorescent light but not under normal light or palpation

Secondary Outcome Measures :
  1. Patient false positive rate [ Time Frame: 30 days ]
    • False Positive Rate at the patient level (FPRp) will be a major secondary efficacy endpoint and is defined as the proportion of folate positive ovarian cancer patients in whom all lesions, without regard to evaluable lesion status, detected by fluorescent light only, are histologically negative

Inclusion Criteria:

  • 1. Female patients 18 years of age and older 2. Have a primary diagnosis, or at high clinical suspicion, of primary ovarian cancer (of epithelial type), planned for primary surgical cytoreduction, interval debulking, or have recurrent ovarian cancer surgery, and:

    • Who are scheduled to undergo laparotomy for the debulking surgery OR
    • Who are scheduled to undergo laparoscopy and pre-authorized to undergo laparotomy for the debulking surgery if cancer is detected on the laparoscopy 3. A negative serum pregnancy test at Screening followed by a negative urine pregnancy test on the day of surgery or day of admission for female patients of childbearing potential 4. Female patients of childbearing potential or less than 2 years postmenopausal agree to use an acceptable form of contraception from the time of signing informed consent until 30 days after study completion 5. Ability to understand the requirements of the study, provide written informed consent for participation in the study and authorization of use and disclosure of protected health information, and agree to abide by the study restrictions and to return for the required assessments

Exclusion Criteria:

  • 1. Previous exposure to OTL38 2. Known FR-negative ovarian cancer 3. Planned surgical debulking via laparoscopy or robotic surgery, with no intent of laparotomy.

    4. Patients with known ovarian cancer miliary disease determined preoperatively to be inoperable.

    5. Any medical condition that, in the opinion of the investigators, could potentially jeopardize the safety of the patient 6. History of anaphylactic reactions 7. History of allergy to any of the components of OTL38, including folic acid 8. Pregnancy or positive pregnancy test 9. Clinically significant abnormalities on electrocardiogram (ECG) 10. Presence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule 11. Impaired renal function defined as eGFR< 50 mL/min/1.73m2 12. Impaired liver function defined as values > 3x the upper limit of normal (ULN) for alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or total bilirubin.

    13. Known Stage IV ovarian cancer with brain metastases 14. Received an investigational agent in another clinical trial within 30 days prior to surgery 15. Known sensitivity to fluorescent light
