A Phase 1b/2 Study to Assess the Safety and Efficacy of HBI-8000 in Combination With Nivolumab in Subjects With Advanced Solid Tumors Including Melanoma, Renal Cell Carcinoma (RCC), and Non-Small Cell Lung Cancer (NSCLC)

A Phase 1b/2 Study to Assess the Safety and Efficacy of HBI-8000 in Combination with
Nivolumab in Patients with Advanced Solid Tumors Including Melanoma, Renal Cell Carcinoma
(RCC), and Non-Small Cell Lung Cancer (NSCLC).

The primary objective of this study is:

-To evaluate the safety and tolerability of HBI-8000 when combined with a standard dose and
regimen of nivolumab, to determine Maximum Tolerated Dose (MTD) and/or Recommended Phase 2
Dose (RP2D) and to evaluate frequency and severity of toxicities of this combination
treatment

The secondary objectives of this study include:

- To explore the efficacy of study treatment as measured by Objective Response Rate (ORR),
Disease Control Rate (DCR), Clinical Benefit Rate (CBR), Duration of Response (DoR),
Progression-Free Survival (PFS) in all subjects treated at RP2D

- To obtain pharmacokinetics of twice weekly HBI-8000 when administered in combination
with nivolumab administered once every two weeks (Phase 1b all sites; Phase 2 selected
sites)

- To characterize the effect of HBI-8000 on the electrocardiogram QT corrected (QTc)
interval (Phase 1b only)

Exploratory:

-To investigate the kinetics and extent of histone acetylation in peripheral blood
mononuclear cells (PBMC) at the RP2D of HBI-8000 (Phase 2 only)

Dose Escalation (Phase 1b) will include up to 18 subjects, followed by Cohort Expansion
(Phase 2) including up to 20 subjects per tumor indication at MTD and/or RP2D (including
those treated in Phase 1b).

Exploratory:

Dose Escalation (Phase 1b) will include up to 18 subjects, followed by Cohort Expansion
(Phase 2) including up to 20 subjects per tumor indication at MTD and/or RP2D (including
those treated in Phase 1b).

HBI-8000 tablets will be administered at 20, 30, 40 mg/dose, orally twice a week until MTD or
40 mg in Phase 2, if MTD is not reached.

Nivolumab: 240 mg intravenous infusions every 2 weeks. A treatment cycle consists of 28 days.
Treatment continues until disease progression or unacceptable toxicity.

Inclusion criteria. Patients may be entered in the study only if they meet all of the
following criteria:

1. Adults at least 18 years of age. 2. Eastern Cooperative Oncology Group (ECOG)
performance status ≤1. 3.

1. Subjects with histopathologically or cytologically confirmed diagnosis of cutaneous
Melanoma, RCC or NSCLC, for whom the use of nivolumab is indicated. NSCLC subjects
with EGFR or ALK genomic aberrations in tumor should have disease progression on
FDA-approved therapy for these aberrations prior to receiving nivolumab (Phase 1b).

2. Subjects with histopathologically or cytologically confirmed diagnosis of cutaneous
Melanoma, or NSCLC, for whom the use of nivolumab is indicated. NCSLC subjects with
EGFR or ALK genomic aberrations in tumor should have disease progression on
FDA-approved therapy for these aberrations prior to receiving nivolumab (Phase 2
expansion).

3. Cutaneous melanoma and NSCLC patients whose disease has progressed after achieving PR
or CR on previous treatment with antagonists to PD1-PD-L1 axis, or patients whose
disease remains stable on previous treatment with antagonists to PD1-PD-L1 axis and
modification to treatment is being considered. NSCLC patients with EGFR or ALK genomic
aberrations in tumor should have disease progression on FDA-approved therapy for these
aberrations prior to receiving nivolumab (Phase 2 expansion).

4. Subject must have at least one measurable target lesion as defined by Response
Evaluation Criteria in Solid Tumors (RECIST) v.1.1.

5. All prior systemic therapy (chemotherapy, mutation targeting therapy, immune
checkpoint therapy), surgical or radiation treatment must have been completed at least
4 weeks before study drug administration (2 weeks for palliative radiotherapy, 1 week
for minor surgery) pending full recovery from therapy.

6. The following laboratory results within 7 days prior to study drug administration:
Adequate hematopoietic, electrolyte, hepatic, and renal laboratory findings as defined
below: WBC ≥3000/μL, Neutrophils ≥1500/μL, Platelets ≥100x103/μL, Hemoglobin ≥9.0g/dL
independent of transfusion, Creatinine ≤1.5mg/dL, AST and ALT ≤3x ULN, Alkaline
phosphatase ≤2.5x ULN unless bone metastases present, Bilirubin ≤1.5x ULN (unless
known Gilbert's disease where it must be ≤3x ULN) and serum albumin ≥3.0g/dL.

7. Life expectancy ≥12 weeks. 8. A negative serum pregnancy test at baseline for women

contraception prior to time of study entry to at least 5 months after the last day of
treatment.

(New York Heart Association Grade III or IV); unstable angina or myocardial
infarction within the previous 6 months; or symptomatic cardiac arrhythmia

3. Uncontrolled hypertension, SBP >160 or DBP >100.

4. Subjects with untreated, or treated brain metastasis, unless stable for 4 weeks

discontinuation

7. Active, known, or suspected autoimmune disease, except for type I diabetes

therapy.

corticosteroids (>10mg daily prednisone equivalents) or other immunosuppressive
medications within 14 days of study drug administration. Inhaled or topical
steroids are permitted.

administration.
