OTL38 Injection for Intraoperative Imaging of Folate Receptor Positive Lung Nodules

This is a phase 2, multi-center, single dose, open-label, exploratory study in suspected lung cancer patients scheduled to undergo endoscopic or thoracic surgery per CT/positron emission tomography imaging based on standard of care. This study aims to assess the efficacy of OTL38 and Near Infrared Imaging (NIR) at identifying pulmonary nodules within the operating theater, and to assess the safety and tolerability of single intravenous doses of OTL38.

About this study

This is a phase 2, multi-center, single dose, open-label, exploratory study in suspected lung cancer patients scheduled to undergo endoscopic or thoracic surgery per CT/positron emission tomography (PET) imaging based on standard of care.

Two to three hours prior to surgery, patients will be infused with OTL38. After the patient is intubated and surgical site incised, the surgeon will locate and document all nodules identifiable by white light, manual palpation, and Near-Infrared Imaging (NIR). This will be documented and recorded. Surgery will be completed per surgeon's standard of care, afterwards the area will be reviewed under standard and infrared light. All samples will be sent for pathology and immunohistochemistry (IHC) evaluation.

Inclusion criteria

  • Male and Female patients 18 years of age and older
  • Confirmed diagnosis of adenocarcinoma lung cancer OR,
  • Have a primary diagnosis, or at high clinical suspicion, of lung nodule(s) warranting surgery based on CT and/or PET imaging
  • Who are scheduled to undergo endoscopic or thoracic surgery surgery
  • 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
  • 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
  • Ability to understand the requirements of the study, provide written informed consent 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

  • Previous exposure to OTL38
  • Known Folate Receptor-negative lung nodules
  • Any medical condition that in the opinion of the investigators could potentially jeopardize the safety of the patient
  • History of anaphylactic reactions or severe allergies
  • History of allergy to any of the components of OTL38, including folic acid
  • Pregnancy, or positive pregnancy test
  • Clinically significant abnormalities on electrocardiogram (ECG) at screening.
  • Presence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule
  • Impaired renal function defined as epidermal growth factor receptor (eGFR) < 50 mL/min/1.73m2
  • Impaired liver function defined as values > 3x the upper limit of normal (ULN) for alanine aminotransferase (ALT) or aspartate aminotransferase (AST), alkaline phosphatase (ALP), or total bilirubin.
  • Received an investigational agent in another investigational drug or vaccine trial within 30 days prior to surgery
  • Known sensitivity to fluorescent light

Primary outcomes

  1. Sensitivity or True Positive Rate (TPR)

    Time frame: 1 day

    Sensitivity or True Positive Rate (TPR) for OTL38 in combination with fluorescent light, defined as the proportion of fluorescent light positive tissue samples (nodule, synchronous lesion, and margin but excluding lymph nodes) that are histologically confirmed to be FR+ and lung cancer by central pathology relative to the total number of tissue samples confirmed to be FR+ and lung cancer by central pathology.

    Sensitivity = (True Positive)/(True Positive +False Negative)

  2. False Positive Rate (FPR)

    Time frame: 1 day

    False positive rate (FPR) for OTL38 in combination with fluorescent light, for the purpose of this protocol, will be calculated as 1 - the Positive Predictive Value (PPV) and is defined as the proportion of fluorescent light positive tissue samples removed (nodule, synchronous lesion, and margin but excluding lymph nodes) that are histologically confirmed to be non-cancerous, or if cancerous, not FR+ and lung cancer, by central pathology relative to the total number of tissue samples removed with fluorescent light imaging. False Positive Rate = (False Positives) / (True Positives + False Positives)

Secondary outcomes

  1. Proportion of Patients With at Least 1 Clinically Significant Event (CSE)

    Time frame: 1 day

    Proportion of patients with at least 1 Clinically Significant Event (CSE as a result of utilizing OLT-38 and Near Infrared Imaging

  2. Positive Margin Identification

    Time frame: 1 day

    Number of patients where at least one positive margin (fluorescent cancerous cells within 5 mm of the staple line) is identified with only OTL-38 and NIR

  3. Synchronous Lesion Identification

    Time frame: 1 day

    Number of patients where at least one synchronous lesions is identified only with OTL-38 and NIR

  4. Pulmonary Nodule Identification

    Time frame: 1 day

    Number of pulmonary nodules identified with OTL-38 and Near Infrared Imaging (NIR) that could not otherwise be identified by white light and palpation.
