Study Details

Study Description

Brief Summary

Open-label, multicenter, phase 1 study to investigate the safety, tolerability, and PK of AN4005 in patients with advanced tumors. This study is a first-in-human, dose escalation study with the objective to establish the MTD and/or RP2D of AN4005.

Except for Dose Level 0 (50 mg), a traditional "3 + 3 design" will be utilized for dose finding with dose escalation and/or de-escalation as appropriate.

Phase 1

Detailed Description

In this study, one sentinel patient will be dosed at 50 mg first, then increasing doses of AN4005 will be administered to cohorts of 3 subjects, at doses ranging from 100 mg twice daily (BID) to 600 mg BID (see the table below). The proposed starting dose, 50 mg BID, has been selected based on integrated data from nonclinical studies. If 50 mg BID for one cycle is deemed to be tolerable upon review of safety data, the dose of AN4005 will be escalated to 100 mg BID in a cohort of 3 patients, and further dose escalations will be performed in separate cohorts based on review of data from all preceding cohorts. The dose escalation will be conducted in a sequential manner. Intermediate dose levels (decrement) may be explored. Decisions with regard to dose escalation to next dose level will be made jointly by the investigators and the sponsor. AE data collected for approximately 90 days following the end of exposure will also be used to inform the final dose and schedule. A minimum of 6 patients will be treated at the MTD/RP2D.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: AN4005 dose level 0

One sentinel patient will be orally dosed at 50 mg AN4005 BID. If this dose for one cycle is deemed to be tolerable upon review of safety data and PK data, the dose of AN4005 will be escalated to next level: dose level 1.

Drug: AN4005-dose level 0
50mg BID

Active Comparator: AN4005 dose level 1

Three patients will be orally dosed at 100 mg AN4005 BID. Based on the number of DLT events during the first cycle, dosing decisions will be made, including add 3 patients at the same dose level (1 DLT), escalation to dose level 3 (<1/6 DLT), de-escalate to lower dose or stop (>1/6 DLT).

Drug: AN4005-dose level 1
100mg BID

Active Comparator: AN4005 dose level 2

Drug: AN4005-dose level 2
200mg BID

Active Comparator: AN4005 dose level 3

Three patients will be orally dosed at 400 mg AN4005 BID. Based on the number of DLT events during the first cycle, dosing decisions will be made, including add 3 patients at the same dose level (1 DLT), escalation to dose level 4 (<1/6 DLT), de-escalate to lower dose or stop (>1/6 DLT).

Drug: AN4005-dose level 3
400mg BID

Active Comparator: AN4005 dose level 4

Drug: AN4005-dose level 4
600mg BID

Active Comparator: AN4005 food effect

The effect of a high-fat meal on the PK of AN4005 will be evaluated in a separate cohort of approximately 6 patients after a safe and clinically relevant dose is identified during the dose finding part of the study.

Highly effective contraception is defined as either:
  • Total abstinence: When this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)

  • Female sterilization: When the female study patient has had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment.

  • Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). For female study patients, the vasectomized male partner should be the sole partner for that patient.

  • Using a combination of any two of the following:

  • Placement of an intrauterine device (IUD) or intrauterine system (IUS), and

  • Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.

  • Hormonal contraception methods (e.g., oral, injected, implanted).

  1. A male participant must agree to use contraception during the treatment period and for at least 90 days after the last dose of the study treatment.
