Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
79 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are assigned to groups based on specific criteria, such as their medical history or a doctor's recommendation. This approach ensures that treatments are given to those who may benefit the most, based on known factors.

Other Ways to Assign Participants
Randomized allocation
: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.

None (Single-arm trial)
: If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled
: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind
: Participants do not know which treatment they are receiving, but researchers do.

Double-blind
: Neither participants nor researchers know which treatment is given.

Triple-blind
: Participants, researchers, and outcome assessors do not know which treatment is given.

Quadruple-blind
: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Study Objectives
Primary Objectives

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent adverse events (TEAE) are defined as any new event reported after first dose of study drug up to 42 days after last dose of study drug, or any event that is worse in severity than at any time during the baseline period. AEs included both SAEs and non-serious adverse events (non-SAEs).

AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AE severity was defined to be the maximum toxicity grade of the treatment-emergent adverse events (TEAEs) experienced by the participants during the study. AE was assessed according to severity; Grade 1 (mild AE), Grade 2 (moderate AE), Grade 3 (severe AE), Grade 4 (life-threatening or disabling AE), Grade 5 (death related to AE). Participants with Grade 3 or higher grades TEAEs were reported.

MTD was defined as highest dose level for which no more than 1 participant in a dose cohort experienced dose limiting toxicity (DLT). DLT was defined as any of the following events occurring during the first 21 days (or 28 days for participants treated every 4 weeks) days of study medication and considered at least possibly-related to study medication: any grade 3 or 4 non-hematologic toxicity except grade 3 alopecia, nausea, or vomiting, any grade 4 febrile neutropenia, any grade 4 thrombocytopenia or any bleeding episode requiring platelet transfusion, any grade 4 absolute neutrophil count (for a duration of greater than or equal to \[\>=\] 7 days), delayed recovery (less than or equal to \[\<=\] grade 1 or baseline) from a toxicity that delays the initiation of the next dose by more than 2 weeks.

DLT was classified as per National Cancer Institute common terminology criteria for adverse events (NCI CTCAE) version 3.0 and defined as any of the following events occurring during the first 21 days (or 28 days for participants treated every 4 weeks) days of study medication and considered at least possibly-related to study medication: any grade 3 or 4 non-hematologic toxicity except grade 3 alopecia, nausea, or vomiting, any grade 4 febrile neutropenia, any grade 4 thrombocytopenia or any bleeding episode requiring platelet transfusion, any grade 4 absolute neutrophil count (for a duration of greater than or equal to \[\>=\] 7 days), delayed recovery (less than or equal to \[\<=\] grade 1 or baseline) from a toxicity that delays the initiation of the next dose by more than 14 days.
Secondary Objectives

PFS was based on Kaplan-Meier estimates. PFS was defined as the time interval from the first dose of study medication until the first date on which relapsed disease, or progression (as per the International Response Criteria for Non-Hodgkin Lymphoma) or death, was documented, censored at the last tumor evaluation date. This outcome measure was analyzed in participants with follicular lymphoma or diffuse large B-cell lymphoma.

OS was based on Kaplan-Meier method. Survival was defined as the time period from the first dose of study drug until the date of death, censored at the participant's last contact date. This outcome measure was analyzed in participants with follicular lymphoma or diffuse large B-cell lymphoma.

This outcome measure was analyzed in participants with follicular lymphoma or diffuse large B-cell lymphoma.

Participants with BOR=with complete response(CR),unconfirmed CR(CRu) or partial response (PR) as per International Response Criteria for NHL. CR: Total disappearance of all detectable clinical,radiographic sign of disease/related symptoms,normalization biochemical abnormalities related to NHL;if enlarged before therapy all lymph nodes,nodal masses,other organs regressed to normal size and spleen regressed in size,undetectable on physical exam,clear bone marrow infiltrate. CRu: CR but allows for residual lymph node mass \>1.5 cm in greatest transverse diameter and all individual nodes previously merged were regressed by \>75% in product diameters and indeterminate bone marrow. PR:\>=50% decrease in sum of products of greatest diameters(SPD) of 6 largest dominant nodes/nodal masses,no increase in size of other nodes/spleen/liver, 50% decrease in SPD of splenic,hepatic nodules,involvement of other organs considered assessable,not measurable disease with exception of splenic,hepatic nodules.

Duration of overall response was defined as the time from the date that measurement criteria were met for CR, CRu, or PR (whichever status was recorded first) until the first date that relapsed disease was objectively documented as per International Response Criteria for NHL, taking as reference for relapsed disease the smallest measurements recorded since the treatment started. This outcome measure was analyzed in participants with follicular lymphoma or diffuse large B-cell lymphoma.

Time to tumor progression was defined as the interval from the start of the treatment until the first date on which relapsed disease or progression is documented, censored at the last disease assessment. This outcome measure was analyzed in participants with follicular lymphoma or diffuse large B-cell lymphoma.
