Brief Summary:
This is a multicenter, open-label, dose escalation Phase 1 study of orally administered CA-4948 monotherapy in adult patients with Acute Myelogenous Leukemia (AML) or high risk Myelodysplastic Syndrome (MDS).

Condition or disease Intervention/treatment Phase
Acute Myelogenous Leukemia Myelodysplastic Syndrome Drug: CA-4948 Phase 1

Detailed Description:

The primary objective of the study is to determine the maximum tolerated dose (MTD) and Recommended Phase 2 Dose (RP2D) for CA-4948 in patients with AML and high risk MDS based on the safety and tolerability, dose-limiting toxicities (DLTs), and Pharmacokinetic (PK)/Pharmacodynamic (PD) findings.

CA-4948 is formulated as tablets for twice daily oral administration. Each treatment cycle will be 28 days in length and repeated in the absence of toxicity. Patients who tolerate CA-4948 may continue to receive CA-4948 until progression of disease, intolerable toxicity, withdrawal from the trial, or study termination.

The starting dose level will be 200 mg twice daily (BID) which was determined to be safe, capable of achieving relevant levels of drug exposure as well as demonstrating signs of biologic activity and clinical efficacy in an ongoing study (Study CA-4948-101). Three patients with AML or MDS will be enrolled at the designated dose. If none of the first 3 patients experience a DLT during the first cycle, patients may be enrolled into the next higher dose level. If 1 patient out of the first 3 experiences a DLT, the dose level may be expanded with an additional 3 patients. If 2 or 3 patients out of the first six experience a DLT, this will be considered a DLT rate above the MTD (> 33%), and additional enrollment will proceed at a lower dose level. Any adverse reaction that leads to dose reduction or discontinuation is considered a DLT unless the adverse reaction is clearly and solely related to disease.

The RP2D will be determined by the Clinical Safety Committee in collaboration with the Sponsor, considering all aspects of safety, tolerability, biologic activity, pharmacokinetics and preliminary efficacy in the trial population. The intent of the RP2D is to provide a dose and schedule that will maximize the opportunity for clinical benefit, while minimizing the risk of toxicity. The RP2D may be below the MTD. The CSC may request enrollment of additional patients at any previously-explored dose level in order to make an appropriate RP2D or MTD determination.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 18 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: Three patients with AML or MDS will be enrolled at the starting dose level. If none of the first 3 patients experience a Dose Limiting Toxicity (DLT) during the first cycle, patients may be enrolled into the next higher dose level. If 1 patient out of the first 3 experiences a DLT, the dose level may be expanded with an additional 3 patients. If 2 or 3 patients out of the first six experience a DLT, this will be considered a DLT rate above the maximum tolerated dose (> 33%), and additional enrollment will proceed at a lower dose level.

Official Title: A Phase 1, Open Label Dose Escalation Trial Evaluating the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of Orally Administered CA-4948 in Patients With Acute Myelogenous Leukemia or Myelodysplastic Syndrome

Arm Intervention/treatment
Experimental: CA-4948 dose escalation
Patients receive CA-4948 PO BID daily. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Drug: CA-4948
CA-4948 is formulated as a tablet for oral administration for BID dosing in consecutive 28-day cycles. CA-4948 is a novel small molecule inhibitor of interleukin-1 receptor-associated kinase 4 (IRAK4),IRAK4 kinase plays an essential role in toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling pathways and these pathways are frequently dysregulated in non-Hodgkin's lymphoma and AML/MDS malignancies.




Primary Outcome Measures :
  1. Determine Maximum Tolerated Dose (MTD) [ Time Frame: 28 days ]
    The highest dose at which there is <33% Dose Limiting Toxicity rate in the first cycle of treatment in a minimum of 6 patients.

  2. Determine the Recommended Phase 2 Dose (RP2D) [ Time Frame: 12 months ]
    The RP2D will be determined by the Clinical Safety Committee (CSC) in collaboration with the Sponsor, considering all aspects of safety, tolerability, biologic activity, pharmacokinetics and preliminary efficacy in the trial population. The intent of an RP2D is to provide a dose and schedule that will maximize the opportunity for clinical benefit, while minimizing the risk of toxicity.


Secondary Outcome Measures :
  1. To characterize the pharmacokinetic (PK) parameters of CA-4948 measured by Cmax [ Time Frame: 12 months ]
    maximum plasma concentration (Cmax)

  2. To characterize the pharmacokinetic (PK) parameters of CA-4948 measured by Cmin [ Time Frame: 12 months ]
    trough plasma concentration (Cmin)

  3. To characterize the pharmacokinetic (PK) parameters of CA-4948 measured by Tmax [ Time Frame: 12 months ]
    Time to maximum plasma concentration

  4. To characterize the pharmacokinetic (PK) parameters of CA-4948 measured by Area under the plasma concentration versus time curve(AUC) [0-24] [ Time Frame: 12 months ]
    area under the plasma concentration-time curve from 0 to 24 hours

  5. To characterize the pharmacokinetic (PK) parameters of CA-4948 measured by AUC[INF] [ Time Frame: 12 months ]
    area under the plasma concentration-time curve from 0 to infinity

  6. To characterize the pharmacokinetic (PK) parameters of CA-4948 measured by T 1/2 [ Time Frame: 12 months ]
    Plasma terminal elimination half-life (T 1/2)
