Detailed Description
The participants will be enrolled during dose escalation and during 2 expansion cohorts of up to 12 participants each.
The dose escalation portion of the trial will incorporate a modified accelerated titration design. Therefore, the trial will enroll 3 participants per dose level with a doubling of the dose at each level during the accelerated stage of the study (skipping every other dose level). Once the first instance of any Grade 3 or higher treatment related toxicity (with some notable exceptions) is observed on the first cycle, the accelerated stage will end and the trial will revert to a conventional design using cohorts of 3 or 6 participants (standard 3+3 design), with single step 2 milligrams (mg)/square meter (m^2) increments.
To further explore the clinical efficacy, additional participants (up to 12 per cohort) may be enrolled at the optimal biologic dose (OBD) or maximum tolerated dose (MTD).
At the end of the study, participants may be enrolled into an open-label extension study (AO-101-EXT [NCT02151903]), at the discretion of the investigator.

Measure Description |
Time Frame |
---|---|---|
Maximum Tolerated Dose (MTD) of DI-Leu16-IL2
Time Frame: First 2 cycles of treatment (each cycle = 21 days)
|
The MTD was determined based on toxicities from the first 2 cycles of treatment.
The MTD was the highest dose tested with no more than 1 participant out of 6 experienced a dose-limiting toxicity (DLT).
All non-hematologic adverse events (AEs) and all hematologic AEs of greater than Grade 3 were considered relevant to determining DLTs.
DLTs included absolute lymphocyte count (ALC) Grade 3 and 4 (if ALC does not resolve to baseline grade according to Common Terminology Criteria for Adverse Events (CTCAE) v4 within 5 days post the final injection per cycle of DI-Leu16-IL2), and absolute neutrophil count (ANC) Grade 3 (If ANC does not resolve to at least Grade 2 within 5 days post the final injection per cycle of DI-Leu16-IL2) and Grade 4 (any).

First 2 cycles of treatment (each cycle = 21 days)
|
Number of Participants With a DLT
Time Frame: First 2 cycles of treatment (each cycle = 21 days)
|
All non-hematologic AEs and all hematologic AEs of greater than Grade 3 were considered relevant to determining DLTs.
DLTs included ALC Grade 3 and 4 (if ALC does not resolve to baseline grade according to CTCAE v4 within 5 days post the final injection per cycle of DI-Leu16-IL2), and ANC Grade 3 (If ANC does not resolve to at least Grade 2 within 5 days post the final injection per cycle of DI-Leu16-IL2) and Grade 4 (any).
|
First 2 cycles of treatment (each cycle = 21 days)
|
Number of Participants With Best Overall Response (BOR) Assessed Per International Workshop for Non-Hodgkin Lymphoma (NHL) Response Criteria
Time Frame: First dose of study drug until first appearance of CR, CRu, PR, SD, or PD (up to 6 months)
|
BOR included complete response (CR), unconfirmed CR (CRu), partial response (PR), stable disease (SD), and progressive disease (PD).
CR: 1) Disappearance of all detectable clinical and radiological evidence of disease; 2) lymph nodes (LN) regressed to normal size; 3) other organs (spleen, liver, kidneys) that were enlarged before therapy must have decreased in size; 4) clear bone marrow (BM) infiltrate.
CRu: must meet CR criteria 1 and 3, as well as ≥1 of following: residual LN mass >1.5 cm in greatest transverse diameter; individual nodes that were previously confluent regressed by >75% in sum of product diameters (SPD); or indeterminate BM.
PR: 6 largest dominant nodes or nodal masses decreased by ≤50% in SPD; no increase in size of other nodes; liver or spleen; splenic and hepatic nodules regressed ≥50% in SPD; and no new disease.
SD: less than a PR but not PD.
PD: 50% increase from nadir in SPD of any abnormal node for PR or nonresponders and appearance of any new lesion.
|
First dose of study drug until first appearance of CR, CRu, PR, SD, or PD (up to 6 months)
|
Tumor Measurement: Percent Change From Baseline in Sum of Product of Diameters at the End of Study
Time Frame: Baseline, end of study (EOS) (up to approximately 3 years)
|
Sum of product diameters sums the product of the 2 tumor measurements on each lesion.
If only 1 measurement was available, it was used as the longest length and the product of the lengths in the sum.
Baseline value is the last non-missing measurement prior to receiving study drug injection.
None of the participants were considered evaluable in 'DI-Leu16-IL2 0.5 mg/m^2' arm for this outcome measure at the end of study, and therefore, data were not collected for that arm.

Baseline, end of study (EOS) (up to approximately 3 years)

Sum of longest diameters is the sum of the longest measured length of each tumor lesion.
Baseline value is the last non-missing measurement prior to receiving study drug injection.
None of the participants were considered evaluable in 'DI-Leu16-IL2 0.5 mg/m^2' arm for this outcome measure at the end of study, and therefore, data were not collected for that arm.
