 (submitted: July 26, 2018)
  • Number of Subjects With Best Overall Tumor Response at the Last Assessment [ Time Frame: up to 3 months ]
    Tumor response was evaluated using computed tomography and categorized according to the Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.1) at Baseline, every 2 cycles, and at the end of the study. Per RECIST, target lesions are categorized as follows: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): ≥ 30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD): ≥ 20% increase in the sum of the longest diameter of target lesions; Stable Disease (SD): small changes that do not meet above criteria.
  • Number of Subjects With Immune-related Tumor Response at the Last Assessment [ Time Frame: up to 3 months ]
    Immune-related tumor response was evaluated by computed tomography at Baseline, every 2 cycles, and at the end of the study. Tumor response was designated according to the immune-related Response Criteria (irRC) (Wolchok et al. Clin Cancer Res 2009;15:7412-20) into the following categories: immune-related complete response (irCR) requires disappearance of all lesions in two consecutive observations not less than 4 weeks apart; immune-related partial response (irPR) requires ≥ 50% decrease in tumor burden compared with baseline in two observations at least 4 weeks apart; immune-related stable disease (irSD) is assigned when neither a 50% decrease from baseline tumor burden nor a 25% increase in tumor burden from nadir can be established; immune-related progressive disease (irPD) requires a ≥ 25% increase from nadir in tumor burden at any single time point in two consecutive observations at least 4 weeks apart.

Brief Title  ICMJE Phase 1/2 Study of Ensartinib and Durvalumab, in ALK-rearranged Non-small Cell Lung Cancer
Official Title  ICMJE A Phase 1/2 Study of ALK Inhibitor, Ensartinib (X-396), and Anti-PD-L1, Durvalumab (MEDI4736), in Subjects With ALK-rearranged (ALK-positive) Non-small Cell Lung Cancer (NSCLC)
Brief Summary This was a Phase 1/2, open-label, multicenter, single-arm study of combination therapy with ensartinib, an anaplastic lymphoma kinase (ALK) inhibitor, and durvalumab, an anti-programmed cell death ligand 1 (PD-L1) antibody, in subjects with ALK-rearranged (ALK-positive) non-small cell lung cancer (NSCLC). Primary study objectives were to determine the recommended combination dose (RCD) and safety and tolerability of the combination. Further objectives were to evaluate the clinical efficacy and biologic activity of the combination.
Detailed Description

Prior to initiation of combination therapy with ensartinib plus durvalumab, subjects were enrolled sequentially to receive ensartinib monotherapy (orally once daily) during a pre-immunotherapy Run-in Period for one to two 28-day cycles. The purpose of the Run-in Period was to determine whether any safety signals might compromise combination therapy and to determine the effect of ALK inhibitor therapy on the immune tumor microenvironment. For subjects with no dose-limiting toxicity (DLT) during the Run-in Period, combination therapy was then initiated during a dose-finding phase using a standard 3 + 3 design until determination of the RCD, which was defined as the highest dose level at which ≤ 1 of 6 subjects (i.e., < 33%) experienced DLTs during the first 2 cycles of combination treatment.

A fixed dose of durvalumab (1500 mg by intravenous [IV] infusion every 4 weeks) was administered in all cohorts. Ensartinib dosing started at 200 mg, with subsequent cohorts receiving a reduced (150 mg) or escalated (225 mg) ensartinib dose depending upon observed toxicity. The study was then designed to include an expansion phase, in which the RCD cohort would be expanded to a total of 20 subjects.

Subjects were monitored for safety (including immune-related adverse events), disease status (using the Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1 and immune-related RECIST), and biologic activity (peripheral blood assays and immunological changes in the tumor microenvironment) for the duration of study participation.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Histologic confirmation of metastatic NSCLC. Subjects must have had confirmed ALK rearrangement as assessed by immunohistochemistry. Subjects may have had prior therapy with ALK inhibitors (other than ensartinib) or been ALK inhibitor naïve. ALK inhibitor naïve subjects were informed of the availability of approved ALK inhibitors.
  2. Measurable disease according to RECIST 1.1, defined as ≥ 1 lesion that could be accurately measured in ≥ 1 dimension (longest diameter to be recorded for non-lymph node lesions, shortest diameter to be recorded for lymph node lesions). Each lesion must have been ≥ 10 mm when measured by computed tomography, magnetic resonance imaging, or caliper measurement by clinical examination or ≥ 20 mm when measured by chest x-ray.
  3. Willing to provide a fresh pre-treatment biopsy; however, if subject was ALK inhibitor naïve, either archival or pre-treatment biopsy was acceptable.
  4. Asymptomatic subjects with surgically treated brain metastases must have been ≥ 14 days post surgery at the time of first dosing, while clinically stable with no requirement for steroids. Asymptomatic subjects with radiation-treated brain metastases may have entered the study immediately after completion of the radiation (and been off steroids, if applicable). Symptomatic subjects (those experiencing headache, seizure etc.), must have been relieved from all symptoms of their central nervous system disease, and must have completed radiation and been off steroids prior to first dosing (anti seizure medicine permitted).
  5. Laboratory parameters for vital functions should have been in the normal range. Laboratory abnormalities that were not clinically significant were generally permitted, except for the following laboratory parameters, which must have been within the ranges specified, regardless of clinical significance:

  3. Active, suspected or prior documented autoimmune disease (including but not restricted to inflammatory bowel disease, celiac disease, Wegner's granulomatosis, Hashimoto's thyroiditis, rheumatoid arthritis, systemic lupus, scleroderma and its variants, multiple sclerosis, myasthenia gravis). Vitiligo, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger were permitted.
  4. Subjects with clinically significant cardiovascular disease, including:

    1. New York Heart Association Class II or higher congestive heart failure.
    2. Myocardial infarction, unstable angina, cerebrovascular accident or transient ischemic attack within 6 months of start of study drug (Day -28).
    3. Clinically significant supraventricular or ventricular arrhythmia.
    4. QT interval corrected using Fridericia's formula (QTcF) ≥ 450 ms (male) or QTcF ≥ 470 ms (female).
    5. Clinically uncontrolled hypertension.
  5. History of pneumonitis or interstitial lung disease, or any unresolved immune-related adverse events following prior therapy.
  6. Major surgery within 4 weeks of starting treatment (or scheduled for surgery during the projected course of the study).
  7. Women of child bearing potential who were pregnant as evidenced by positive serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin) or nursing.
  8. Female subjects of childbearing potential who were sexually active with a non-sterilized male partner must have used at least one highly effective method of contraception (see table below) from the time of screening and must have agreed to continue using such precautions for 90 days after the final dose of investigational products. Non-sterilized male partners of a female subject must have used male condoms plus spermicide throughout this period. Cessation of birth control after this point should have been discussed with a responsible physician. Not engaging in sexual activity for the total duration of the trial and the drug washout period was an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method were not acceptable methods of birth control.

    Female subjects should have refrained from breastfeeding throughout the period described above.

    Females of childbearing potential were defined as those who were not surgically sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or post-menopausal.

    Females were considered post-menopausal if they had been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements applied:

    • Females <50 years of age were considered post-menopausal if they had been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they had luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
    • Females ≥50 years of age were considered post-menopausal if they had been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year prior to study entry, had chemotherapy-induced menopause with last menses >1 year prior to study entry, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).

    Non-sterilized male subjects who were sexually active with a female partner of childbearing potential must have used male condoms plus spermicide from screening through 90 days after receipt of the final dose of investigational products. Male subjects were to refrain from sperm donation throughout this period. Female partners (of childbearing potential) of a male subject must have used a highly effective method of contraception (see table below) throughout this period. Cessation of birth control after this point was to be discussed with a responsible physician. Not engaging in sexual activity for the total duration of the trial and the drug washout period was an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method were not acceptable methods of birth control.

    A highly effective method of contraception was defined as one that resulted in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Note that some contraception methods were not considered highly effective (e.g. male or female condom with or without spermicide; female cap, diaphragm, or sponge with or without spermicide; non-copper containing intrauterine device; progestogen-only oral hormonal contraceptive pills where inhibition of ovulation was not the primary mode of action [excluding Cerazette/desogestrel which was considered highly effective]; and triphasic combined oral contraceptive pills).

  9. Subjects who were immunosuppressed, including those with known immunodeficiency.
  10. Active infection including tuberculosis (clinical evaluation that included clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice), hepatitis B (known positive hepatitis B virus surface antigen result), hepatitis C, or human immunodeficiency virus (positive 1/2 antibodies). Subjects with a past or resolved hepatitis B virus infection (defined as the presence of hepatitis B core antibody and absence of hepatitis B virus surface antigen) were eligible. Subjects positive for hepatitis C antibody were eligible only if polymerase chain reaction was negative for hepatitis C virus ribonucleic acid.
  11. History of severe allergic reactions to any unknown allergens or components of the study drugs.
  12. Other serious illnesses (e.g., serious infections requiring antibiotics, bleeding disorders).
  13. Mental impairment that may have compromised compliance with the requirements of the study.
  14. Lack of availability for immunological and clinical follow-up assessment.
  15. Inability to swallow or retain oral medication, presence of active gastrointestinal disease or other condition that would have interfered significantly with the absorption, distribution, metabolism, or excretion of ensartinib.
  16. Any condition that, in the clinical judgment of the treating physician, was likely to prevent the subject from complying with any aspect of the protocol or that may have put the subject at unacceptable risk.
  17. History of allogeneic organ transplant.
  18. Subjects must not have donated blood while on study and for at least 90 days following the last durvalumab treatment.
