Inclusion Criteria

1. =18 years of age
2. Diagnosis of active CLL or SLL that meets at least one of the IWCLL 2008 criteria for requiring treatment (Binet Stage = B and/or Rai Stage = I)
3. Disease that has progressed during or relapsed after at least one previous CLL/SLL therapy
4. Not appropriate for treatment with a purine-based analogue regimen (per NCCN or ESMO guidelines), including relapse =36 months from a purine-based chemoimmunotherapy regimen or relapse =24 months from a purine-based monotherapy regimen
5. A cytogenetics or FISH analysis of the leukemic cells within 24 months of randomization is required to document the presence or absence of del(17p). Note: if a sample from within 24 months is not available, it should be collected as part of the screening laboratory evaluation
6. Measurable disease with a lymph node or tumor mass =1.5 cm in at least one dimension as assessed by computed tomography (CT)
7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 (corresponds to Karnofsky Performance Status [KPS] =60%)
8. Willingness by subject to be randomized to receive either ofatumumab or IPI-145 at the dose and schedule defined in the protocol
9. For women of childbearing potential (WCBP): negative serum ß-human chorionic gonadotropin (ßhCG) pregnancy test within 1 week before randomization (WCBP defined as a sexually mature woman who has not undergone surgical sterilization or who has not been naturally post-menopausal for at least 24 consecutive months [women =55 years] or 12 consecutive months [women >55 years])
10. Willingness of male and female subjects who are not surgically sterile or postmenopausal to use medically acceptable methods of birth control from the first dose of study drug to 30 days after the last dose of IPI-145 and for 12 months after last dose of ofatumumab. Sexually active men, and women using oral contraceptive pills, should also use barrier contraception
11. Ability to voluntarily sign consent for and adhere to the entire study visit schedule and all protocol requirements
12. Signed and dated institutional review board (IRB)/independent ethics committee (IEC)-approved informed consent form (ICF) before any study specific screening procedures are performed
