Inclusion Criteria:
Subjects must satisfy the criteria below to be enrolled in dose escalation (Part A) and in
dose expansion (Part B) of this study.
1. Men and women = 18 years of age, at the time of signing the ICF.
2. Subject must understand and voluntarily sign an ICF prior to any study-specific
assessments/procedures being conducted.
3. Subject is willing and able to adhere to the study visit schedule and other protocol
requirements.
4. Subjects with histological or cytological confirmation of either:
Advanced or unresectable ST, laBCC or R/R NHL.
- Subjects with solid tumors including those who have progressed on (or not been
able to tolerate due to medical comorbidities or unacceptable toxicity) standard
anticancer therapy or for whom no other approved conventional therapy exists.
- Subjects with laBCC must have unresectable disease which must have progressed
after treatment with a smoothened inhibitor (SMOi) or who are intolerant of SMOi
on (or not been able to tolerate due to medical comorbidities or unacceptable
toxicity).
- For relapsed/ refractory NHL following at least 2 prior lines of therapy (e.g.
subjects have failed at least one line of standard therapy and have received at
least one prior line of salvage therapy) OR have failed at least one prior line
of standard therapy and are not eligible for autologous stem cell transplant
(ASCT) OR have declined ASCT; transformed lymphoma following chemotherapy for
lower grade lymphoma and at least one standard treatment regimen for DLBCL.
- Subjects with two or more lines of systemic therapy who have been treated
with and have lack of response or have responded and relapsed after chimeric
antigen receptor T-cell (CAR-T) therapy, if such therapy is available, OR
are ineligible for CAR-T therapy at the time of enrollment, OR declined
CAR-T therapy.
Subjects must have at least one site of measurable disease according to RECIST 1.1
Previously irradiated lesions are not considered evaluable; for subjects with R/R NHL,
bi-dimensionally measurable disease on cross sectional imaging by CT or MRI, with at
least one lesion >1.5 cm in its greatest transverse diameter, as defined by the IWG
criteria. For subjects with rare malignancies, not falling into the above categories
and who might benefit from a treatment with BET inhibitor, evaluable disease can be
considered.
5. Subjects consent to tumor archive material analysis. Tumor biopsies to be collected
whenever safe and feasible will be collected in Part A. Subjects consents to mandatory
tumor biopsies (Screening and on treatment) in Part B.
6. ECOG PS of 0 to 1.
7. Subjects must have the following laboratory values at Screening:
- Absolute neutrophil count (ANC) = 1.5 x 109/L without growth factor support for 7
days (14 days if subject received peg-filgrastim).
- Hemoglobin (HGB =10 g/dL (= 8g/dL for DLBCL subjects).
- Platelet count (PLT) =150 x 109/L (=100 x 109/L without transfusion for 7 days
for DLBCL subjects).
- Serum potassium concentration within normal range, or correctable with
supplements
- Serum glutamic oxaloacetic transaminase (SGOT)/aspartate aminotransferase (AST)
and serum glutamate pyruvic transaminase (SGPT)/alanine aminotransferase (ALT) =
3.0 x Upper Limit of Normal (ULN).
- Serum total bilirubin = 1.5 x ULN.
- Serum creatinine = 1.5 x ULN or measured glomerular filtration rate (GFR) = 50
mL/min/1.73 m2 using an exogenous filtration marker such as iohexol, inulin, 51Cr
EDTA or 1125 iothalamate, or creatinine clearance of = 50 mL/min using
Cockroft-Gault equation.
- Subjects must have serum albumin > 3.5 g/dL.
- PT (or INR) and APTT within normal range.
8. Subjects must agree not to share study drugs with another person
9. Females of childbearing potential
- A female of childbearing potential (FCBP) is a female who: 1) has achieved
menarche at some point, 2) has not undergone a hysterectomy or bilateral
oophorectomy, or 3) has not been naturally postmenopausal (amenorrhea following
cancer therapy or other medical condition does not rule out childbearing
potential) for at least 12 consecutive months and verified by an FSH blood test
at screening.
- FCBP must either commit to true abstinence from heterosexual intercourse (which
must be reviewed monthly and source documented) or to use one highly effective
contraceptive method plus one barrier method. True abstinence is acceptable when
this is in line with the preferred and usual lifestyle of the subject. (Periodic
abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and
withdrawal are not acceptable methods of contraception). Highly effective
contraceptive methods are combined (containing estrogen and progestogen) or
progestogen-only hormonal contraception associated with inhibition of ovulation
(oral, injectable, intravaginal, patch, or implantable); bilateral tubal
ligation; intrauterine device; intrauterine hormone-releasing system; or
vasectomized partner sterilization (note that vasectomized partner is a highly
effective birth control method provided that partner is the sole sexual partner
of the FCBP trial participant and that the vasectomized partner has received
medical assessment of the surgical success). Barrier methods are male or female
latex or synthetic condom, diaphragm, cervical cap or sponge with spermicide,
barrier contraceptive with spermicide. These measures should be used from signing
the ICF, throughout the study, and for up to 44 days following the last dose of
CC-95775.
- Have two negative pregnancy tests as verified by the investigator prior to
starting CC-95775.
- Pregnancy testing:
- A negative serum pregnancy test (or ß-subunit of human chorionic gonadotropin
(ß-hCG pregnancy test) at Screening verified by the Investigator.
- A negative serum or urine pregnancy test (or ß-subunit of human chorionic
gonadotropin (ß-hCG pregnancy test) on Day 1 of dosing verified by the
Investigator prior to dosing.
- Agree to ongoing pregnancy testing during the course of the study, and after the
end of study treatment. This applies even if the subject practices true
abstinence from heterosexual contact.
10. Male subjects must practice true abstinence (which must be reviewed on a monthly
basis) or agree to use a condom (a latex or non-latex synthetic condom is required)
during sexual contact with a pregnant female or a FCBP and will avoid conceiving from
signing the ICF, while participating in the study, during dose interruptions, and for
at least 104 days following CC-95775 discontinuation, even if he has undergone a
successful vasectomy. True abstinence is acceptable when this is in line with the
preferred and usual lifestyle of the subject [female partner's periodic abstinence
(e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are
not acceptable methods of contraception].
- Males must agree not to donate semen or sperm for at least 104 days following
CC-95775 discontinuation.
- Other than the subject, FCBP and males able to father a child should not handle
the study drugs or touch the capsules, unless gloves are worn.
