Study Description

Brief summary:

CC-95775-ST-001 is an open-label, Phase 1B, dose escalation and expansion study of CC-95775 in subjects with advanced or unresectable solid tumors, including laBCC, and relapsed/ refractory non-Hodgkin's lymphoma (NHL). The dose escalation part (Part A) of the study will explore escalating oral doses of CC-95775 administered on a 4d on/24d off schedule to estimate the MTD of CC-95775. A mTPI-2 will help guide CC-95775 dose escalation decisions with the final decisions made by an SRC. Approximately 20 subjects will be enrolled. The expansion cohort (Part B) will evaluate the safety, PK, PD safety and preliminary activity of CC-95775 in advanced solid tumors, including laBCC. Approximately 20 subjects will be enrolled.

Arms and interventions
Arm Intervention/treatment
Experimental: CC-95775
Escalating dose finding part A of study and extension Part B of the study. In Part A, subjects will be treated with oral capsules of CC-95775 with a schedule of 4d on/ 24d off (Q4W) and a starting dose of 100 mg/day on a 28-day cycle. Dose increments between cohorts will not exceed 100% of the dose in previous cohort. Patients in Part B will be treated with a schedule of 4d on/24d off (Q4W) at the Maximum tolerated dose (MTD) established from Part A.
Drug: CC-95775
Outcome Measures
  • Primary Outcome Measures: 1. Dose Limiting Toxicity (DLT) [ Time Frame: C1 Up to approximately 28 days ]
    is defined as any toxicities occurring within the DLT assessment unless the event can clearly be determined to be unrelated to CC-95775.
  • 2. Maximum Tolerated Dose (MTD) [ Time Frame: Part A of the study- estimated 12 months ]
    dose level that could be given such that the estimated DLT probability is closest to 25%.
  • 3. Non-tolerated Dose (NTD) [ Time Frame: Part A of the study-estimated 12 months ]
    The dose that is higher than MTD
  • 4. Adverse Events (AEs) [ Time Frame: From signature of the informed consent until at least 28 days after the last dose of study treatment ]
    Number of participants with adverse event. An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study
  • Secondary Outcome Measures: 1. Pharmacokinetics - Cmax of CC-95775 [ Time Frame: Part A and part B of the study, estimated 24 months total ]
    Maximum plasma concentration of drug
  • 2. Pharmacokinetics - AUC of CC-95775 [ Time Frame: Part A and part B of the study, estimated 24 months total ]
    Area under the curve
  • 3. Pharmacokinetics - Tmax of CC-95775 [ Time Frame: Part A and part B of the study, estimated 24 months total ]
    Time to peak plasma concentration
  • 4. Pharmacokinetics - t1/2 of CC-95775 [ Time Frame: Part A and part B of the study, estimated 24 months total ]
    Half-life the time it takes for the concentration of the drug in the plasma to be reduced by 50%
  • 5. Pharmacokinetics - CL/F of CC-95775 [ Time Frame: Part A and part B of the study, estimated 24 months ]
    Measurement of the volume of plasma from which a substance is completely removed per unit time
  • 6. Pharmacokinetics - Vz/F of CC-95775 [ Time Frame: Part A and part B of the study, estimated 24 months ]
    Apparent volume of distribution. It is the volume needed to account for the total amount of drug in the body if the drug was evenly distributed throughout the body and in the same concentration as the site of sample collection such as peripheral venous plasma
  • 7. Evaluate the pharmacodynamic (PD) effects of CC-95775 on gene expression in peripheral blood and in tumor tissue. [ Time Frame: Part B of the study, estimated 12 months ]
    Changes in the expression of genes associated to BET inhibitors in PBMCs and/or other genes, such as GLI1, MYC, in tumor biopsy may provide confirmation that a dose is pharmacologically active and enable identification of dose, which results in optimal target engagement

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

- Have two negative pregnancy tests as verified by the investigator prior to
starting CC-95775.

- Pregnancy testing:

- A negative serum pregnancy test (or β-subunit of human chorionic gonadotropin
(β-hCG pregnancy test) at Screening verified by the Investigator.

- A negative serum or urine pregnancy test (or β-subunit of human chorionic
gonadotropin (β-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.
