Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
Selected

* Measurable or non-measurable disease as per RECIST v1.1 criteria and documented by CT and/or MRI. In Cohort Expansion, patients with truly non-measurable only disease (e.g., ascites, pleural or pericardial effusion, organomegaly), are not eligible for enrollment
* In Dose Escalation patients must have selected tumor types and have progressed after standard of care treatment, or be intolerant to treatment, or refused standard treatment
* Part 2 includes but is not limited to:
* Renal cell cancer progressing during or following at least two approved therapeutic regimens (e.g., small molecule inhibitors, anti-PDx therapy)
* Cutaneous melanoma that is either locally unresectable or metastatic:

* BRAF wild type: progressed after receiving PD-1 containing therapy with or without an anti-CTLA-4
* BRAF mutation: patients who refused BRAF+MEK inhibitor
* NSCLC: Unresectable locally advanced or metastatic PD-L1-positive (= 1%) NSCLC not harboring an activating EGFR mutation or ALK rearrangement and has progressed during or following treatment with an anti-PDx and platinum-based chemotherapy (unless ineligible for platinum therapy)
* Part 3: NSCLC as described above
* Female patients of childbearing potential must have a negative serum or urine pregnancy test performed within 72 hours prior to the initiation of study drug administration. Female patients of childbearing potential must be willing to use two forms of contraception throughout the study, starting with Screening through 60 days after the last dose of study drug. Abstinence is acceptable if this is the established and the preferred contraception method for the patient
* Male patients with partners of childbearing potential must use barrier contraception from the time of consent through 60 days after discontinuation of study drug and must not donate sperm during this period. In addition, male patients should have their partners use contraception (as documented for female patients) for the same period of time
* Patients who have previously received an immune checkpoint inhibitor (e.g., anti-PD-L1, anti-PD-1, anti-CTLA-4) prior to enrollment must have checkpoint inhibitor immune-related toxicity resolved to either Grade = 1 or baseline (prior to the checkpoint inhibitor) to be eligible for enrollment. Patients who experienced previous checkpoint inhibitor-related hypothyroidism are eligible for the study regardless of grade resolution if well controlled on thyroid hormone replacement therapy
* Symptomatic central nervous system (CNS) metastases must have been treated, be asymptomatic for = 14 days, and meet the following at the time of enrollment:

* No concurrent treatment for CNS disease (e.g., surgery, radiation, corticosteroids = 10 mg prednisone/day or equivalent)
* No concurrent leptomeningeal disease or cord compression
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Patients with a history of known autoimmune disease with exceptions of

* Vitiligo
* Psoriasis, atopic dermatitis, or other autoimmune skin condition not requiring systemic treatment
* History of Graves' disease in patients now euthyroid for > 4 weeks
* Hypothyroidism managed by thyroid hormone replacement
* Alopecia
* Arthritis managed without systemic therapy beyond oral nonsteroidal anti- inflammatory drugs
* Major surgery or traumatic injury within 8 weeks before first dose of AU-007
* Unhealed wounds from surgery or injury
* Treatment with > 10 mg per day of prednisone (or equivalent) or other immune-suppressive drugs within the 7 days prior to the initiation of study drug. Steroids for topical, ophthalmic, inhaled, or nasal administration are allowed
* Prior anti-cancer therapy before the planned start of AU-007 as follows:

* Not recovered to baseline from toxicity of prior systemic cancer therapy(ies).
* Not recovered from toxicity of radiotherapy.
* Concurrent use of hormones either to maintain castrate levels of testosterone in patients with castration-sensitive prostate cancer or for non-cancer-related conditions (e.g., insulin for diabetes, hormone replacement therapy) is acceptable. Bisphosphonates are permitted.
* Patients who have experienced serious adverse events during prior IL-2 therapy (including but not limited to bowel perforation, gastrointestinal bleeding, arrythmias, myocardial infarction, repetitive seizures).
* Inflammatory process that has not resolved for = 4 weeks from the date of first study dose. Patients with chronic low-grade inflammatory processes such as radiation-induced pneumonitis are excluded regardless of duration
* Second primary invasive malignancy not in remission for = 1 year. Exceptions include non-melanoma locally advanced skin cancer, cervical carcinoma in situ, localized prostate cancer (Gleason score = 7), resected melanoma in situ, or any malignancy considered to be indolent and never required therapy, with the exception of indolent lymphomas

Summary
Brief summary
This is a first in human, open-label, multi-center Phase 1 / 2 study to evaluate the safety, tolerability, and initial efficacy of AU-007 in patients with advanced solid tumors. AU-007 will be administered either as a monotherapy, or in combination with a single loading dose of aldesleukin, or with both AU-007 and aldesleukin given every 2 weeks (Q2w). Once the recommended phase 2 dose (RP2D) of AU-007 plus aldesleukin is determined, AU-007 plus aldesleukin will also be administered with avelumab.
