ADMIRAL Trial: Adaptive Mediastinal Radiation with Chemo-Immunotherapy

Trial Status: Approved

This phase II trial studies two questions in patients with stage III NSCLC: 1) does it improve cancer control to add the drug Durvalumab, a type of immunotherapy, earlier in the treatment course; and 2) by intensifying treatment with durvalumab, is it possible to avoid mediastinal radiation to decrease side effects, without decreasing cancer control?

Inclusion Criteria

  • Histologically or cytologically documented non-small cell lung cancer (NSCLC)
  • Stage III NSCLC according to American Joint Committee on Cancer (AJCC) staging version (v)8

  • A maximum of 20 patients with bulky mediastinal disease will be allowed on this trial, defined as at least one contiguous mediastinal mass with minimum diameter > 2 cm, that is not contiguous with the primary tumor (and therefore would not be irradiated during radiation to the primary tumor)

  • Measured creatinine clearance (CL) > 60 mL/min or calculated creatinine CL > 50 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance

Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations
  • Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: * Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy) * Women >= 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy)
  • Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up

Exclusion Criteria

  • Prior anti-CTLA-4, PD-1 or PD-L1 antibodies including durvalumab
  • Prior chemotherapy in the past 3 years from consent
  • Any unresolved toxicity National Cancer Institute (NCI) CTCAE grade >= 2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria * Patients with grade >= 2 neuropathy will be evaluated on a case-by-case basis after consultation with the study physician * Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the study physician
  • Prior thoracic radiation that would preclude curative-intent radiation dose as outlined in this study
  • Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study
  • History of allogenic organ transplantation
  • Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). The following are exceptions to this criterion: * Patients with vitiligo or alopecia * Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement * Any chronic skin condition that does not require systemic therapy * Patients without active disease in the last 5 years may be included but only after consultation with the study physician * Patients with celiac disease controlled by diet alone
  • Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring adverse events (AEs) or compromise the ability of the patient to give written informed consent
  • History of leptomeningeal carcinomatosis
  • History of active primary immunodeficiency
  • Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis (TB) testing in line with local practice), hepatitis B (known positive hepatitis B virus [HBV] surface antigen [HBsAg] result), hepatitis C. Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. Patients positive for hepatitis C (hepatitis C virus [HCV]) antibody are eligible only if polymerase chain reaction is negative for HCV ribonucleic acid (RNA)
  • Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion: * Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection) * Systemic corticosteroids at physiologic doses not to exceed <<10 mg/day>> of prednisone or its equivalent * Steroids as premedication for hypersensitivity reactions (e.g., computed tomography [CT] scan premedication)
  • Receipt of live attenuated vaccine within 30 days prior to the first dose of investigational product (IP). Note: Patients, if enrolled, should not receive live vaccine whilst receiving IP and up to 30 days after the last dose of IP
  • Female patients who are pregnant or breastfeeding or male or female patients of reproductive potential who are not willing to employ effective birth control from screening to 90 days after the last dose of durvalumab monotherapy
  • Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients

PRIMARY OBJECTIVE:

I. To compare the 1-year progression free survival (PFS) rate in patients treated with concurrent chemotherapy, durvalumab and hypofractionated radiation therapy to the primary lung tumor followed by response adaptive mediastinal radiation and durvalumab relative to historical data on durvalumab maintenance therapy (PACIFIC-2 trial).

SECONDARY OBJECTIVES:

I. Evaluation of the frequency and severity of pneumonitis.

II. To evaluate overall survival (OS).

III. To evaluate the pathologic response rate of the mediastinum to chemo-immunotherapy plus primary lung tumor radiation.

IV. To evaluate the objective response rate (complete response [CR] or partial response [PR], confirmed and unconfirmed) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

V. To evaluate the frequency and severity of toxicities graded with Common Terminology Criteria for Adverse Events (CTCAE), version 5.

OUTLINE:

Patients will receive platinum doublet chemotherapy per standard of care with durvalumab for 8 weeks, concurrent with a short course of radiation to the primary lung tumor. Patients will then undergo repeat evaluation of the mediastinal lymph nodes. If there is no cancer in the lymph nodes, patients will receive 2 years of adjuvant durvalumab. If there is still cancer in the lymph nodes, patients will receive 6 weeks of radiation to the mediastinal lymph nodes, and 2 years of adjuvant durvalumab.

After the completion of study treatment, patients are followed up for 12 months.
