| Diffuse Large B Cell Lymphoma DLBCL Cancer | Drug: Rituximab Drug: Cyclophosphamide Drug: Doxorubicin Drug: Vincristine Drug: Prednisone Biological: Pegfilgrastim | Phase 2 |
This study will test the efficacy of split-dose R-CHOP for the treatment of elderly patients with de novo diagnosis of DLBCL or transformed DLBCL. Split-dose R-CHOP involves giving Cyclophosphamide, Doxorubicin, Vincristine, Prednisone (CHOP) chemotherapy at 14 days' interval with Rituximab given once/month. The safety for every 14-day CHOP administration was studied in a large prospective randomized control trial of patients up to the age of 80 years. In this study, R-CHOP given every 14 days for up to 6 cycles was felt to be the best method of delivery of chemotherapy. Receiving greater than 6 cycles of R-CHOP chemotherapy was not found to be beneficial compared to participants receiving 6 cycles of R-CHOP. Additionally, an interim response adapted approach by combining imaging and MRD testing will be used to identify participants who will receive an abbreviated chemotherapy course if they are both Positron Emission Tomography/Computed Tomography (PET/CT) and Minimum Residual Dose (MRD) negative.
In the proposed study, participants will receive a 50% dose reduction of CHOP chemotherapy on Day 1 and Day 15 of each cycle with full dose Rituximab on Day 1 for up to a total of 6 months of chemotherapy. Participants who are MRD and PET/CT negative after 2 months will be placed on an abbreviated regimen with R-CHOP x 4 additional doses with full dose Rituximab and a 50% dose reduction in CHOP chemotherapy. The hypothesis is that this method of administration of R-CHOP will be a safe and effective form of chemotherapy for older patients with DLBCL and will allow older patients to receive curative intent treatment.

- Complete Response Rate (CR) [ Time Frame: up to 6 months ]Simon 2-stage design with complete response (CR) rate at the end of treatment as our primary outcome. 40% is an unacceptable boundary for complete response rate and 60% as an acceptable complete response rate. CR at the end of treatment, will be estimated as the observed proportion and presented with a 95% Wilson confidence interval.
- Progression Free Survival (PFS) [ Time Frame: up to 2 years 6 months ]PFS measures survival without relapse/progression or death starting from study enrollment. Relapse or progression of disease and death will be considered as events; subjects who survive without recurrence or progression will be censored at last contact. PFS will be estimated using the Kaplan Meier estimate and presented with graphically with pointwise 95% confidence intervals.
- Overall Survival (OS) [ Time Frame: up to 2 years 6 months ]OS measures time to death starting from study enrollment. Death from any cause will be considered an event; surviving subjects will be censored at time of last follow-up. OS will be estimated using the Kaplan-Meier estimate and presented with graphically with pointwise 95% confidence intervals. Exploratory Cox proportional hazards regression will be used to evaluate the effect of baseline covariates on PFS and OS.
- Incidence of Treatment Emergent Adverse Events [ Time Frame: up to 2 years 6 months ]The incidence of serious adverse events will be reported for all subjects who received at least one dose of the study treatment. The proportion of subjects experiencing a Serious Adverse Event (SAE) will be reported with 95% confidence intervals overall, as well as classified by grade and organ system. Toxicity will be monitored using the formal boundary described in the protocol.
- Cancer-Specific Geriatric Assessment [ Time Frame: up to 2 years 6 months ]Cancer-specific geriatric assessment prior to, during, and after completion of chemotherapy treatments to evaluate for changes in physical function, mental health, cognition, and other relevant geriatric specific outcomes. The geriatric assessment measures will be summarized descriptively at each measurement time-point using appropriate descriptive statistics such as frequencies and percentages with standard errors for categorical variables, mean with standard error or median with quartiles for continuous variables.

| Ages Eligible for Study: | 70 Years and older (Older Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Signed and dated informed consent document indicating that the participant (or legally acceptable representative) has been informed of all pertinent aspects of the trial
-
All patients age ≥75 years and participants aged 70-74 years who are determined to be unfit or frail by Cumulative Illness Rating Score-Geriatrics (CIRS-G) scale
- For participants aged 70-74 years: CIRS-G score with 5-8 comorbid conditions scored 2 or ≥1 comorbidity scored 3-4. CIRS-G score is to be reviewed by the study PI prior to enrollment.

Participants with discordant bone marrow (i.e. involved by low-grade/indolent NHL) are eligible. Participants with transformed DLBCL from underlying low-grade disease are eligible. Participants with composite DLBCL and concurrent low-grade lymphoma are eligible.
