Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryMaximum Tolerated Dose (MTD) of Interleukin 15First 28 days of treatment
The MTD is the dose level at which no more than 1 of up to 6 participants experience a dose-limiting toxicity (DLT) during the DLT evaluation window(s), or the dose below that at which at least 2 (of ≤6) participants have DLT. A dose-limiting toxicity (DLT) is defined as: any grade 3, 4, or 5 toxicity, if not incontrovertibly due to disease progression or an extraneous cause, and deemed possibly, probably or definitely related to interleukin-15 (IL-5) by the principal investigator (PI) or designee during the first 28 days of treatment. Grade 3 is severe. Grade 4 is life threatening. Grade 5 is death related to adverse event.
SecondaryMean Progression Free Survival (PFS)From study opening through May 2022 when the study was completed with a maximum follow up of approximately 2 years and 11 months for any participant.
PFS is defined as the duration of time from the date of study enrollment until time of disease relapse, disease progression, or death, whichever occurs first. Disease relapse is Disease progression is \>20% increase in the sum of longest diameters of target lesions or appearance of a new lesion assessed by the Response Evaluation Criteria in Lymphoma (RECIL) 2017 criteria.
SecondaryMean Event-free Survival (EFS)From study opening through May 2022 when the study was completed with a maximum follow up of approximately 2 years and 11 months for any participant.
EFS is defined as the duration of time from the date of study enrollment until time of disease relapse, disease progression, alternative therapy for lymphoma given (such as radiation), or death, whichever occurs first, and was estimated using Kaplan-Meier curves along with a 95% confidence interval. Disease relapse is Disease progression is \>20% increase in the sum of longest diameters of target lesions or appearance of a new lesion assessed by the Response Evaluation Criteria in Lymphoma (RECIL) 2017 criteria.
SecondaryMean Overall Survival (OS)From study opening through May 2022 when the study was completed with a maximum follow up of approximately 2 years and 11 months for any participant.OS is defined as the time from the date of study enrollment until time of death from any cause and was estimated using Kaplan-Meier curves along with a 95% confidence interval.
SecondaryOverall Response in Participants With Greater Than or Equal to 50% Programmed Death-ligand 1 (PD-L1) Expressing Tumor CellsFrom the time the subject began protocol treatment until end of treatment, progression or start of another therapy or approximately 2 years
Response was assessed by the Response Evaluation Criteria in Lymphoma (RECIL) 2017 criteria and reported along with a 95% confidence interval. Complete response is complete disappearance of all target lesions. Partial response is ≥30% decrease in the sum of longest diameters of target lesions but not a complete response. Minor response is ≥10% decrease in the sum of longest diameters of target lesions but not a partial response. Stable disease is \<10% decrease or ≤20% increase in the sum of longest diameters of target lesions. Disease progression is \>20% increase in the sum of longest diameters of target lesions or appearance of a new lesion.
SecondaryNumber of Participants With Overall Best Response6 cycles (each cycle is 28 days) - approximately 168 days
OR is the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Complete response is complete disappearance of all target lesions. Partial response is ≥30% decrease in the sum of longest diameters of target lesions but not a complete response. Minor response is ≥10% decrease in the sum of longest diameters of target lesions but not a partial response. Stable disease is \<10% decrease or ≤20% increase in the sum of longest diameters of target lesions. Disease progression is \>20% increase in the sum of longest diameters of target lesions or appearance of a new lesion assessed by the Response Evaluation Criteria in Lymphoma (RECIL) 2017 criteria.
SecondaryMean Duration of Response (DOR)From the time that response to therapy is first documented until progressive disease is observed or the subject is lost to follow-up or approximately 2 years.
DOR is measured from the time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is recorded first) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started), death, or, in the absence of progressive disease (PD), date of last assessment. The response rate was assessed by the Response Evaluation Criteria in Lymphoma (RECIL) 2017 criteria and reported along with a 95% confidence interval. Complete response is complete disappearance of all target lesions. Partial response is ≥30% decrease in the sum of longest diameters of target lesions but not a complete response. Disease progression is \>20% increase in the sum of longest diameters of target lesions or appearance of a new lesion.
OtherNumber of Participants With a Dose-limiting Toxicity (DLT)First 28 days of treatment
A dose-limiting toxicity (DLT) is defined as: any grade 3, 4, or 5 toxicity if not incontrovertibly due to disease progression or an extraneous cause, and deemed possibly, probably or definitely related to interleukin-15 (IL-5) or avelumab by the principal investigator (PI) or designee during the first 28 days of treatment. Grade 3 is severe. Grade 4 is life threatening. Grade 5 is death related to adverse event.
OtherNumber of Participants With Serious and/or Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0)Date treatment consent signed to date off study, approximately 21 months and 18 days for the dose level 1 and 3 months and 19 days for the dose level 2.
Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
