Lung Cancer Clinical Trial
Chemoradiation Followed by Durvalumab in Poor Risk and/or Elderly Patients With Stage III NSCLC
Elderly (age 70 years or older) or >18 years old AND poor risk (ECOG 2) newly diagnosed stage IIIA-C (AJCC 8th edition) inoperable non-small cell lung cancer (NSCLC) patients are eligible to participate in this phase II open label study of concurrent, split course chemoradiation followed by Durvalumab (MEDI4736).
The rationale for the study is to identify another cohort of stage III NSCLC for whom adjuvant Durvalumab can be safely given, expanding its utilization and benefits. With a unique, extremely well-tolerated 4-phase split course CRT regimen preceding the administration of Durvalumab, we expect to be able to offer adjuvant Durvalumab to a significant proportion of patients on study.
Patients who have completed four cycles of chemoradiation (Radiation is 60 Gy in 30 fractions administered over 12 weeks with 1-1.5 week breaks between cycles; Chemotherapy is once every 3 weeks for up to 4 cycles) will go on to receive durvalumab (MEDI4736) monotherapy as 1500mg durvalumab (MEDI4736) via IV infusion Q4W for up to a maximum of 12 months (up to 13 doses/cycles) with the last administration on week 48 until confirmed disease progression unless there is unacceptable toxicity, withdrawal of consent, or another discontinuation criterion is met.
Primary objectives are:
To determine the percentage of poor risk and/or elderly unresectable stage III NSCLC patients who complete split course chemoradiation
To determine the safety and tolerability of durvalumab (MEDI4736) after completion of chemoradiation in this group of patients.
Secondary Objectives are:
To determine the 1-year overall survival rate
To determine the 1-year progression-free survival rate
To determine the 1-year loco-regional progression-free survival rate
To determine rate of grade 3 and 4 toxicities with this regimen in the selected patient population
Participants must have histologically or cytologically confirmed stage IIIA-C (AJCC 8th edition) non-small cell lung cancer, that will be treated with curative intent.
Participants must have been deemed medically inoperable by multidisciplinary team/tumor board
Participants must have been staged with a PET/CT within 30 days of enrollment
Patients must have undergone an MRI Brain w/IV contrast, or CT brain if MRI not feasible, confirming no evidence of brain metastases, within 30 days of enrollment.
Participants must be elderly (age 70 years or older and PS 0-1) or >18 years old AND poor risk (ECOG 2)
Participants ideally have endobronchial ultrasound biopsy (EBUS) or mediastinoscopy to confirm nodal status, but can be deferred if PET/CT imaging characteristics are highly suggestive of nodal metastases
Participants should have a life expectancy of >6 months
Participants must have normal organ and marrow function: Leukocytes >3000/mcL; ANC >1500/mcL; PLT>100000/mcL; Hemoglobin ≥9.0 g/dL
Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN)
AST/ALT <2.5 x institutional upper limit of normal
Measured creatinine clearance (CL) >40 mL/min or Calculated creatinine CL>40 mL/min by the Cockcroft-Gault formula
Creatinine CL (mL/min) = Weight (kg) x (140 - Age) 72 x serum creatinine (mg/dL)
Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL)
Patients must be capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act in the US, European Union [EU] Data Privacy Directive in the EU) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations. If study includes Japan add (For patients aged <20 years and enrolling in Japan, a written informed consent should be obtained from the patient and his or her legally acceptable representative.)
Body weight >30kg
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.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to carboplatin, pemetrexed (for patients with adenocarcinoma), etoposide (for patients with squamous cell carcinoma), or immunotherapy
Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic CHF, unstable angina pectoris, cardiac arrhythmia, or psychiatric/social situations that would limit compliance with study requirements.

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
Receipt of the last dose of anticancer therapy (CRT) ≤7 days prior to the first dose of study drug. If sufficient wash-out time has not occurred due to the schedule or PK properties of an agent, a longer wash-out period will be required, as agreed by AstraZeneca/MedImmune and the investigator
Any unresolved toxicity 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.
