The main purpose of this study is to examine how two separate groups of 17p deletion Chronic lymphocytic leukemia (CLL) participants respond to sequential treatment with this particular combination of drugs. The two groups are those participants who have previously received treatment for their CLL and those who have not yet received any treatment. The combination of drugs is Ofatumumab and High-Dose Methylprednisolone (HDMP) first followed by Ofatumumab and Alemtuzumab. All three drugs are FDA approved and have known activity in treating 17p CLL. We hope that by combining these drugs together in this study, they will have more benefit than each one alone and that the subjects' CLL will be significantly impacted.
Participants were assigned to 1 of 2 groups based on prior treatment status. Both groups received the same therapy.
Part A: Ofatumumab + HDMP 2-4 cycles Part B: Ofatumumab + Alemtuzumab 1-6 cycles Part C: Maintenance with Ofatumumab + Alemtuzumab up to 2 years
Between days 15-22 of Cycle 2 of Part A, participants are restaged. Participants who achieve nodal complete response discontinue Part A therapy and undergo minimal residual disease (MRD) assessment to guide the decision whether to go to Part B or Part C. The participants with persistent disease after 2 cycles of Part A therapy receive 2 more cycles of Part A therapy and then undergo another restaging as well as MRD assessment. At restaging, participants with minimal disease are eligible for Part C or allogeneic stem cell transplant (SCT) off protocol. The remaining participants receive Part B therapy. On Part B, restaging occurs at weeks 12 and 18. If MRD negative complete response (CR) status is achieved then therapy is discontinued and the primary endpoint evaluation occurs 2 months later. Otherwise with persistent disease Part B therapy continues up to 24 weeks and the primary endpoint evaluation occurs after Part B therapy is completed. Participants who achieve clinical complete response may receive Part C therapy or be observed while waiting SCT.

| Induction Overall Response Rate (ORR) | Induction ORR is the percentage of participants achieving a minimum of partial response (PR) over induction treatment based on International Workshop on Chronic Lymphocytic Leukemia (IW-CLL) criteria (Hallek, et al 2008). There are numerous diagnostic tests used for response evaluation including potentially CBC and differential count, marrow aspirate and biopsy, ultrasound of the abdomen, CT scans (chest, pelvis, abdomen) and physical examination. PR is a 50% or greater decrease of measured size of lymphadenopathy, hepatomegaly, splenomegaly as well as blood lymphocytes (over baseline), marrow infiltrate or B-lymphoid nodules and a 50% or greater increase from baseline in platelet count (or level >100,000/micro liter), hemoglobin (or level >11 grams/deciliter), neutrophils (or level >1500/microliter). | Disease was evaluated after weeks 8 and 16 of Part A and at 12, 18 and 24 weeks during part B. |

Adverse Events (AEs) were collected weekly during cycle 1 Part A and then every other week for the duration of Part A (up to 16 weeks); every cycle for the duration of Part B (up to 24 weeks); and every 56 days for the duration of Part C (up to 104 weeks). AEs in summary were collected up to 144 weeks of treatment plus 30 days.
Maximum grade toxicity by type was first calculated. Serious AEs were defined as events with treatment attribution of possibly, probably or definitely and grade 3 or higher. All remaining events regardless of treatment attribution were classified as Other AEs. Grades 1-2 AEs were not required reporting per protocol; all AEs collected were included in the calculation. No further data is available to specify classification of system organ class "Other" per CTCAEv4 criteria beyond the general term.

| Secondary | Transplant Rate | Percentage of participants eligible for allogeneic hematopoietic stem cell transplantation (alloHSCT) that are able and willing to proceed to alloHSCT. | Posted | Number | 90% Confidence Interval | percentage of participants | Evaluated up to 36 cycles (approximately 2.75 years) of treatment (Parts A, B and C) |
|
|
|
| Secondary | Number of Participants With Treatment-Related Grades 1-3 Hyperglycemia During Part A Induction | Participants ever experiencing a grade 1-3 hyperglycemia event based on CTCAEv4 with treatment attribution of possible, probably or definite as reported on case report forms were counted. | Posted | Number | participants | Adverse Events (AEs) were collected weekly during cycle 1 Part A and then every other week for the duration of Part A (up to 16 weeks) |
|
|
|
| Secondary | 3-Year Progression-Free Survival (PFS) Probability | 3-year PFS is the probability of participants remaining alive and progression-free at 3 years from study entry estimated using Kaplan-Meier methods. Disease progression (PD) per International Workshop on Chronic Lymphocytic Leukemia (IW-CLL) criteria (Hallek, et al 2008) is: the appearance of any new lesion (enlarged lymph node minimum >1.5 centimeters); an increase by 50% in greatest determined diameter of any previous site; an increase in the previously noted enlargement of the liver or spleen by 50% or more or the de novo appearance of hepatomegaly, splenomegaly; a 50% increase of blood lymphocytes (over baseline with level at least 5,000/microliter); occurrence of cytopenia secondary to CLL at least 3 months post treatment including a 50% or greater decrease from baseline in platelet count (or level <100,000/microliter) or a hemoglobin decrease of >2 grams/deciliter (or level <10 grams/deciliter); and transformation to a more aggressive histology. | Posted | Number | 95% Confidence Interval | percentage probability | Disease was evaluated on treatment after weeks 8 and 16 of Part A, at 12, 18 and 24 weeks during part B and every 6 months on Part C as well as off-treatment every 3 months up to 5 years. |
|
|
|
| Secondary | 3-year Overall Survival (OS) Probability | 3-year OS is the probability of participants remaining alive at 3 years from study entry estimated using Kaplan-Meier methods. | Posted | Number | 95% Confidence Interval | percentage probability | Median survival follow-up was 45 months (range 31-58 months) in this study cohort. |
|
|
|
| Secondary | Number of Participants Completing Part A Treatment | Participants counted as completing Part A with either 2 or 4 cycles of treatment per protocol. | Posted | Number | participants | Evaluated up to 4 cycles/16 weeks. |
|
|
|
| Secondary | Number of Participants Completing Only 2 Cycles of Part A Treatment | Participants counted if only completed 2 cycles of Part A treatment per protocol. | Posted | Number | participants | Evaluated after 2 cycles/8 weeks of Part A therapy. |

| EG001 | Relapsed/Refractory | Participants were assigned to 1 of 2 groups based on prior treatment status. Both groups received the same therapy. (cycle duration=28 days) Part A: Ofatumumab + HDMP 2-4 cycles Ofatumumab: 1000 mg IV Days 1, 8, 15, 22 High-Dose Methylprednisolone (HDMP): 1000 mg/m2 IV Days 1-3 Participants who have not experienced a clinical complete response with no residual detectable disease after Part A will continue on to Part B. Part B: Ofatumumab + Alemtuzumab 1-6 cycles Ofatumumab: 1000 mg IV Day 1 Alemtuzumab: 30 mg subcutaneously Days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24 and 26 Participants who have experienced at least stable disease in Parts A and B can continue on to Part C. Participants who are eligible may instead proceed to stem cell transplantation after Parts A and B. Part C: Maintenance with Ofatumumab + Alemtuzumab up to 2 years Ofatumumab: 1000 mg IV every other cycle Alemtuzumab: 30 mg subcutaneously Days 14, 28 | 6 | 15 | 9 | 15 | 14 | 15 |
