FR-2, A Phase II Study to Assess the Activity of PD-L1 Inhibition with Durvalumab (MEDI4736) after Chemo-Radiotherapy in Patients with Stage II-IV Microsatellite Stable (MSS) Rectal Cancer

Purpose: 

This study is being done to look at the safety and response to the investigational drug durvalumab (MEDI4736) following chemo-radiation therapy for patients with MSS stage II to IV rectal cancer. Durvalumab recognizes specific proteins on the surface of cancer cells and triggers the immune system to destroy the cancer cells. The chemoRT portion of the treatment will be completed just before the course of durvalumab is initiated.

In order to learn more about certain characteristics of rectal cancer tumors, this study includes special research tests using samples from diagnostic tumors, a tissue sample from tumors removed during surgery, fresh tumor samples from an area where the cancer has recurred, and blood samples.

Ages Eligible for Study:  18 Years and older   (Adult, Senior)

Sexes Eligible for Study:  All

Accepts Healthy Volunteers:  No

Inclusion Criteria:

The ECOG performance status must be 0 or 1

Patients with biopsy-proven adenocarcinoma, stage II- IV rectal cancer.

The tumor must have been determined to be mismatch repair proficient or microsatellite stable through CLIA approved testing (Immunohistochemistry [IHC], polymerase chain reaction [PCR], or Next-Generation Sequencing [NGS] assays).

Patients must be candidates for planned surgical resection of their primary rectal cancer 8 - 12 weeks after completion of neoadjuvant chemoRT, even if stage IV.

Planned neoadjuvant chemoRT treatment must conform to NCCN guidelines.

Baseline staging prior to chemoRT initiation must be obtained. If stage IV, there must be documentation by PET/CT scan, CT scan, or MRI, that the patient has evidence of measurable distant disease per RECIST 1.1. Note: Patients with stage IV disease should have limited but measurable metastatic disease (one or two organs involved e.g., liver and lung) and primary tumor deemed resectable.

Blood counts performed within 4 weeks prior to study entry must meet the following criteria:

ANC must be greater than or equal to 1500/mm3

Platelet count must be greater than or equal to 75,000/mm3; and

Hemoglobin must be greater than or equal to 9 g/dL.

Adequate hepatic function performed within 4 weeks prior to study entry must be met:

Total bilirubin must be less than or equal to 1.5 x ULN (upper limit of normal) for the lab unless the patient has a bilirubin elevation greater than 1.5 x Upper limit of normal (ULN) to 3 x ULN due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and

AST and ALT must be less than or equal to 2.5 x ULN for the lab with the following exception: for patients with documented liver metastases, AST and ALT must be less than or equal to 5 x ULN.

Adequate renal function within 4 weeks of study entry, defined as serum creatinine less than or equal to 1.5 x ULN for the lab. (If creatinine is 1.0-1.5 x ULN, the creatinine clearance should be greater than 40 mL/min per Cockcroft-Gault formula (Cockcroft-Gault 1976), or by 24-hour urine collection for determination of creatinine clearance.)

Patients with reproductive potential (male/female) must agree to use accepted and highly effective methods of contraception while receiving durvalumab, and for at least 3 months after the last dose of durvalumab.

Female patients must either be of non-reproductive potential (i.e., post-menopausal by history: greater than or equal to 60 years old and no menses for greater than or equal to 1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.

Exclusion Criteria:

Diagnosis of anal or small bowel carcinoma.

Histopathology other than adenocarcinoma, e.g., sarcoma, lymphoma, carcinoid.

Previous therapy with any PD1 or PD-L1 inhibitor (including durvalumab) for any malignancy.

Completion of pelvic radiotherapy treatment for this current rectal cancer or any prior pelvic radiotherapy (e.g., prior prostate or cervical cancer therapy).

Receipt of live attenuated vaccination within 30 days prior to study entry or within 30 days after receiving the last dose of durvalumab.

Acute or chronic hepatitis B or hepatitis C.

Known history of human immunodeficiency virus (HIV) or acquired immunodeficiency-related (AIDS) illnesses.

History of brain metastases, uncontrolled spinal cord compression, carcinomatous meningitis, or new evidence of brain or leptomeningeal disease.

Active infection or chronic infection requiring chronic suppressive antibiotics.

History of allogeneic organ transplantation.

Active or prior documented inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis).

Active or prior history of autoimmune or inflammatory condition requiring ongoing immunosuppressive medications. This specifically includes use of immunosuppressive medication within 28 days before the first dose of durvalumab with the exceptions of intranasal corticosteroids or systemic corticosteroids at physiological doses, which do not exceed 10mg/day of prednisone or an equivalent corticosteroid.

Any of the following cardiac conditions:

Documented NYHA Class III or IV congestive heart failure

Myocardial infarction within 6 months prior to study entry

Unstable angina within 6 months prior to study entry

Symptomatic arrhythmia

Prolonged QTc greater than or equal to 470 ms. If QTc greater than or equal to 470ms, confirmation of eligible QTc requires mean calculation from 2 additional electrocardiograms (ECGs) 2−5 minutes apart using Fridericia's Correction Formula (mean less than 470 ms).

Uncontrolled high blood pressure defined as systolic BP greater than or equal to 150 mmHg or diastolic BP greater than or equal to 100 mmHg with or without anti-hypertensive medication. Patients with initial BP elevations are eligible if initiation or adjustment of BP medication lowers pressure to meet entry criteria.

Ongoing or active gastritis or peptic ulcer disease.

Active bleeding diatheses which in the opinion of the treating physician poses a significantly increased operative risk.

Known history of previous diagnosis of tuberculosis.

History of hypersensitivity to durvalumab or any excipient.

Known history of active pneumonia, pneumonitis, symptomatic interstitial lung disease, or definitive evidence of interstitial lung disease described on CT scan, MRI, or chest x-ray in asymptomatic patients; dyspnea at rest requiring current continuous oxygen therapy.

Other malignancies unless the patient is considered to be disease-free and has completed therapy for the malignancy greater than or equal to 12 months prior to study entry. Patients with the following cancers are eligible if diagnosed and treated within the past 12 months: carcinoma in situ of the cervix, colorectal carcinoma in situ, melanoma in situ, and basal cell and squamous cell carcinoma of the skin.

Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would preclude the patient from meeting the study requirements, or interfere with interpretation of study results.

Pregnancy or lactation at the time of study entry. (Note: Pregnancy testing should be performed within 14 days prior to study entry according to institutional standards for women of childbearing potential.)

Use of any investigational agent within 4 weeks prior to study entry.
