For this pharmacokinetics (PK) primary outcome measure the serum rituximab Ctrough for SC and IV administrations were measured at Cycle 7, 21 days after study treatment administration for Cycle 7 (pre-dose of Cycle 8). Geometric mean ratio and 90% confidence interval were estimated based on an ANCOVA model adjusted for tumor load at baseline and are reported in the statistical analysis.

Secondary Outcome Measures

Observed SC and IV Rituximab Area Under the Curve (AUCsc and AUCiv)
The area under the curve (AUC) for serum rituximab concentration versus time after dosage was measured for SC and IV administrations during Cycle 7. Geometric mean ratio and 90% confidence interval were estimated based on an ANCOVA model adjusted for tumor load at baseline and are reported in the statistical analysis.
Maximum Observed Serum Concentration (Cmax) of Rituximab
Time to Cmax (Tmax) of Rituximab
Trough Serum Concentration (Ctrough) of Rituximab
Ctrough was measured at Cycle 2 and Cycle 7, 21 days after study treatment administration for each cycle (pre-dose of Cycle 3 and Cycle 8, respectively).
Area Under the Curve (AUC) of Rituximab
AUC is the area under the serum concentration curve over the dosing interval of 21 days during Cycle 2 and Cycle 7.
Complete Response Rate (CRR) as Determined by the Independent Review Committee (IRC) Using Lugano Response Criteria (LRC) for Malignant Lymphoma
Per LRC, CR based on positron emission tomography- computed tomography (PET-CT) was defined as complete metabolic response (MR) in lymph nodes and extralymphatic sites with a score of 1, 2, or 3 with or without residual mass, on 5-point scale (5PS), where, 1= no uptake above background; 2 = uptake ≤ mediastinum; 3 = uptake > mediastinum but ≤ liver; 4 = uptake moderately > liver; 5 = uptake markedly higher than liver and/or new lesions; no new lesions and no evidence of fluorodeoxyglucose (FDG)-avid disease in bone marrow.

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
AE: any untoward medical occurrence in a subject administered a pharmaceutical product, regardless of causal attribution. An AE can be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. New disease, exacerbation of existing disease, recurrence of an intermittent medical condition not present at baseline, any deterioration in a laboratory value or other clinical test associated with symptoms or leading to a change in study/concomitant treatment or discontinuation from study drug as well as events related to protocol-mandated interventions are considered AEs. SAEs: any event that met any of these criteria: fatal, life-threatening, required or prolonged in-patient hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, medically significant or required intervention to prevent any of the outcomes listed here.
Number of Participants With Rituximab Administration-related Reactions (ARRs)
Adverse events occurring within 24 hours after administration of rituximab (rituximab IV or rituximab SC) and considered related to the study drug, were considered as ARRs. ARRs could present with one or more of the following symptoms: allergic reaction, arthralgia, bronchospasm, chills, cough, dizziness, dyspnoea, headache, hypertension, hypotension, myalgia, nausea, pruritus, pyrexia, rash, tachycardia, urticaria, vomiting.
Number of Participants Positive for Anti-drug Antibodies (ADAs) to Rituximab
Reported here is the number of participants who had a positive ADA assay result at baseline or post-baseline. The post-baseline results are divided in treatment-enhanced ADAs and treatment-induced ADAs. Treatment-enhanced ADAs are participants with a positive ADA result at baseline who had one or more post-baseline titer results that was at least 0.60 titer unit greater than the baseline titer result. Treatment-induced ADAs include participants with negative or missing baseline ADA result(s) and at least one positive post-baseline ADA result.
Number of Participants Positive for Anti-rHuPH20 Antibodies
Reported here is the number of participants who had a positive anti-rHuPH20 antibody assay result at baseline or post-baseline. The post-baseline results are divided in treatment-enhanced anti-rHuPH20 antibodies and treatment-induced anti-rHuPH20 antibodies. Treatment-enhanced anti-rHuPH20 antibodies are participants with a positive anti-rHuPH20 antibody result at baseline who had one or more post-baseline titer results that was at least 0.60 titer unit greater than the baseline titer result. Treatment-induced anti-rHuPH20 antibodies include participants with negative or missing baseline anti-rHuPH20 antibody result(s) and at least one positive post-baseline anti-rHuPH20 antibody result.
