Brief Summary:
This phase I trial studies the side effects and best dose of AOH1996 in treating patients with solid tumors that do not respond to treatment (refractory). AOH1996 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Condition or disease Intervention/treatment Phase
Refractory Malignant Solid Neoplasm Drug: PCNA Inhibitor AOH1996 Phase 1

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) and the dose limiting toxicities (DLT) of PCNA inhibitor AOH1996 (AOH1996).

II. To establish the recommended phase 2 dose (RP2D) of AOH1996.

SECONDARY OBJECTIVES:

I. To determine the pharmacokinetics of AOH1996. II. To evaluate for preliminary efficacy of AOH1996. III. To evaluate response rate and disease control rate in solid tumors.

EXPLORATORY OBJECTIVE:

I. To determine pharmacodynamics parameters (alteration of gammaH2AX, downregulation of Myc) of AOH1996.

OUTLINE: This is a dose-escalation study.

Patients receive AOH1996 orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of adverse events (AEs) [ Time Frame: Up to 30 days after last study drug is given ]
    Toxicity and adverse events will be recorded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. All toxicities/AEs will be recorded from the initiation of protocol therapy through the follow-up period.

  2. Dose limiting toxicities [ Time Frame: Up to 28 days (cycle 1) ]
    Toxicities will be graded according to NCI CTCAE version 4.0.


Secondary Outcome Measures :
  1. Response rate [ Time Frame: Up to 2 years ]
    Will be assessed using Response Evaluation Criteria in Solid Tumors version 1. Response rate will be estimated in the overall population and 95% exact confidence intervals will be estimated.

  2. Progression-free survival [ Time Frame: Assessed up to 2 years ]
    Time to disease progression/ relapse or death as a result of any cause.

  3. Overall survival [ Time Frame: Assessed up to 2 years ]
    Time to death as a result of any cause.

  4. Time to treatment failure [ Time Frame: Assessed up to 2 years ]
    Time to treatment termination for any reason (progression, toxicity, death, patient preference).


Other Outcome Measures:
  1. Levels of plasma gammaH2AX [ Time Frame: Up to 2 years ]
    Will use descriptive statistics and graphical displays to summarize levels of plasma gammaH2AX, evaluate changes between pre- and post-treatment measurements. A paired t-test will be used to determine if there is a statistically significant change.
