OUTLINE: This is a dose-escalation study of olaparib.
Patients receive olaparib orally (PO) twice daily (BID) on days -11 to -3, vorinostat PO on
days -10 to -3, gemcitabine intravenously (IV) over 4.5 hours on days -9 and -4, busulfan IV
over 3 hours on day -9 to -6, melphalan IV over 30 minutes on days -4 and -3, and undergo
peripheral blood stem cell transplant IV over 30-60 minutes on day 0. Patients with CD20+
tumors also receive rituximab IV over 3-6 hours on day -10.
After completion of study treatment, patients are followed up every 1-2 days for 30 days and
then every 2 weeks for up to 100 days.

(CAR-T) in a timely fashion or have already failed these; B) Hodgkin's with one of the
following: B.1) primary refractory (no CR or progressive disease [PD] within 3
months), B.2) high-risk relapse (CR1 < 1 year, extranodal relapse, B symptoms), B.3)

they must be =< 5 x ULN.

potential: negative urine or serum pregnancy test within 28 days and within 72 hours
of study treatment and confirmed prior to receiving treatment on this study. Patients
with positive results will be removed from the study. Postmenopausal is defined as: 1.
amenorrheic for 1 year or more following cessation of exogenous hormonal treatments.
2. luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the
postmenopausal range for women under 50. 3. radiation-induced oophorectomy with last
menses > 1 year ago. 4. chemotherapy-induced menopause with > 1 year interval since
last menses. 5. surgical sterilization (bilateral oophorectomy or hysterectomy). 6.
female patients must agree to use a highly effective birth control method while on
study and for at least 1 month after your last dose of study drug(s).
- Male patients and their partners, who are sexually active and of childbearing
potential, must agree to the use of two highly effective forms of contraception in
combination, throughout the period of taking study treatment and for 3 months after
last dose of study drug(s) to prevent pregnancy in a partner.
