Brief Summary

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, 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)
• To obtain pharmacokinetics of twice weekly HBI-8000 when administered in combination with nivolumab administered per package insert dose and administration (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)
• To explore potential biomarkers for disease response through sequential sampling of blood and/or tumor tissue in subjects consenting to correlative sub-studies at participating sites (Phase 2 only) Dose Escalation (Phase 1b) will include up to 18 subjects, followed by Cohort Expansion (Phase 2) including up to 100 subjects (melanoma up to 60 subjects and NSCLC up to 40 subjects at MTD and/or RP2D.

Outcome Measures

Primary Outcomes (1)

• Number of Patients Who Experienced at Least One DLT During the DLT Assessment Period for MTD Determination

  The dose escalation schema of HBI 8000 followed the conventional 3+3 design. The starting dose was HBI 8000 20 mg twice a week. Dose escalation to 30 mg or 40 mg was determined by observation of DLT. At each dose level, a minimum of 3 subjects evaluable for DLT were enrolled. If 0 of the initial 3, or no more than 1 in a total 6 subjects experienced DLT, escalation to the next higher dose was allowed.

  First 28 days

Secondary Outcomes (14)

• Objective Response Rate (ORR) in All Patients Treated at RP2D

  From screening for baseline assessment to the date of CR or PR assessed, up to approximately 4 years and 7 months

• Disease Control Rate (DCR) in All Patients Treated at RP2D

  From screening for baseline assessment to the date of best response (CR, PR, or SD) on study, up to approximately 4 years and 7 months

• Duration of Response (DoR) in All Patients Treated at RP2D

  From the date of CR or PR until the date of PD, or until the date of death, up to approximately 4 years and 7 months

• Progression-Free Survival (PFS) in All Patients Treated at RP2D

  From the date of first dose of HBI-8000 until tumor progression by site reported RECIST 1.1, or clinical progression, or death, whichever occurs first, up to approximately 4 years and 7 months

• Pharmacokinetic - Cmax (Single Dosing)

  From predose (0.5 hour prior to breakfast) to 7 hours postdose on Cycle 1 Day 1, at 24 hours on Cycle 1 Day 2 (no dose administered)

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects were entered in the study only if they met all of the following criteria:
• \. Adults at least 18 years of age. 2. Eastern Cooperative Oncology Group (ECOG) performance status ≤1. 3.
• Subjects with histopathologically or cytologically confirmed diagnosis of non uveal melanoma, RCC, or NSCLC, for whom the use of nivolumab was 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).
• Subjects with histopathologically or cytologically confirmed diagnosis of non uveal melanoma or NSCLC for whom the use of nivolumab is indicated (Phase 2 expansion). With Protocol Amendment 5, subjects with NSCLC were not eligible for enrollment.
• c, Non uveal melanoma and NSCLC subjects whose disease progressed after achieving stable disease (SD) for at least 3 months, with partial response (PR) or complete response (CR) as the best response that was documented by imaging studies on previous treatment with a PD L1 inhibitor with proven efficacy (Phase 2 expansion).
