About this study

Part A of this trial consists of 4 treatment arms of DKN-01. It is a dose escalation study in patients with multiple myeloma or advanced solid tumors. Patients must be refractory or intolerant to all standard/approved therapy(ies). At each dose level, 3 subjects will be treated. If none of the 3 subjects develop a dose limiting toxicity after a minimum of 4 weeks of treatment, subsequent dose escalation will proceed according to the same schedule. Part B consists of dose confirmation in patients with NSCLC. Patients must be refractory or intolerant to all standard/approved therapy(ies). Approximately 15 patients may be enrolled in Part B.

Treatment and study plan

DKN-01

Drug

DKN-01 will be administered intravenously (IV) once a week over 30 minutes (min) and 2 hours (max) for 75, 150 and 300 mg. At 600 mg, DKN-01 will be administered by IV on days 1 and 15 of each cycle. PART A - Dose Escalation: 3 participants will be treated with a 28 day cycle of DKN-01 at an assigned dose level until disease progression. Dose escalation will occur sequentially over the doses of 75, 150, 300, and 600 mg until the criteria for reaching maximum tolerated dose (MTD) are met (or highest planned dose study group is completed). Cycle 1 will define the dose limiting toxicity (DLT) that governs dose escalation. PART B - Dose Confirmation: Once the MTD is established (or the highest planned dose level), 300 mg of DKN-01 will be administered IV on days 1 and 15 of every 28 day cycle.

Primary outcomes

  1. Summary of Total Adverse Events (AE)

    Time frame: Baseline to study completion (approximately 3 months)

    Total Adverse Events (AE), total treatment emergent adverse events (TEAE), total Serious Adverse Events (SAE), and total dose-limiting toxicity (DLT) for both Parts A and B.

  2. Summary of Patients With Adverse Events (AE)

    Time frame: Baseline to study completion (approximately 3 months)

    Number of patients who had Adverse Events (AE) including treatment related treatment emergent adverse events (TEAE), Common Toxicity Criteria for Adverse Effects (CTCAE), and Serious Adverse Events (SAE) for both Parts A and B. Severity was coded to NCI CTCAE version 4.02. For maximum severity and relationship, patients were counted only once in the most severe or most related category.

  3. Progression Free Survival (PFS) in Patients With Relapsed or Refractory Non-small Cell Lung Cancer (NSCLC)

    Time frame: Time from the date of signed informed consent to the first date of objectively determined progressive disease or death from any cause

    For Part B only. The distribution of PFS was estimated using the Kaplan-Meier (KM) method. PFS was defined as the time from the date of signed informed consent to the first date of objectively determined progressive disease (Progression is defined by Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) and International Multiple Myeloma Working Group (IMWG)) or death from any cause. For patients who were still alive at the time of analysis (ie, data cut-off date) and without evidence of tumor progression, PFS was censored at the date of the most recent objective progression-free observation.

Secondary outcomes

  1. Pharmacokinetics: Area Under the Concentration - Time Curve (AUC) of DKN-01

    Time frame: Cycle 1 Day 1 (first dose, all groups)

    Area under the DKN-01 serum concentration-time profile curve during the dosing interval (AUC0-tau) after the first and fourth infusion for both Parts A and B. Cycle 1 Day 1 included once per week (QW) dosing groups and every two weeks (Q2W) dosing groups.

  2. Pharmacokinetics: Area Under the Concentration - Time Curve (AUC) of DKN-01

    Time frame: Cycle 1 Day 22 (Fourth Dose for QW)

    Area under the DKN-01 serum concentration-time profile curve during the dosing interval (AUC0-tau) after the first and fourth infusion for both Parts A and B. Cycle 1 day 22 included only QW dosing groups.

  3. Pharmacokinetic: Maximum Plasma Concentration (Cmax) of DKN-01

    Time frame: Cycle 1 Day 1 (first dose, all groups)

    Peak DKN-01 serum concentration (Cmax) after the first and fourth infusion on Cycle 1 Weeks 1 and 4, for both Parts A and B. Cycle 1 Day 1 included once per week (QW) dosing groups and every two weeks (Q2W) dosing groups.

  4. Pharmacokinetic: Maximum Plasma Concentration (Cmax) of DKN-01

    Time frame: Cycle 1 Day 22 (Fourth dose for QW groups)

    Peak DKN-01 serum concentration (Cmax) after the fourth infusion on Cycle 1 Weeks 1 and 4, for both Parts A and B. Cycle 1 day 22 included only QW dosing groups.

  5. Progression Free Survival (PFS) in Patients Who Are Refractory or Intolerant to Standard/Approved Therapies

    Time frame: Time from the date of signed informed consent to the first date of objectively determined progressive disease or death from any cause

    For both Parts A and B. PFS was defined as the time from the date of signed informed consent to the first date of objectively determined progressive disease (Progression is defined by Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) and International Multiple Myeloma Working Group (IMWG)) or death from any cause. For patients who were still alive at the time of analysis (i.e, data cut-off date) and without evidence of tumor progression, PFS was censored at the date of the most recent objective progression-free observation.

  6. Overall Survival (OS) in Patients With Relapsed or Refractory NSCLC

    Time frame: Time from the date of signed informed consent to the date of death from any cause

    For Part B only. OS was defined as the time from the date of signed informed consent to the date of death from any cause. For patients who were still alive as of the data cut-off date, OS time was censored on the date of the patient's last contact (last contact for patients in post-discontinuation was the last date of contact in long-term follow-up eCRF).

  7. Objective Response Rate (ORR) in Oncologic Patients Who Are Refractory or Intolerant to Standard/Approved Therapies

    Time frame: Part A: Every 2 months; Part B: after 1 month and every two cycles thereafter

    For both Parts A and B. Objective response rate is defined as the number of patients with overall best response of complete response (CR) or partial response (PR)

  8. Objective Response Rate (ORR) in Patients With Relapsed or Refractory Non-small Cell Lung Cancer (NSCLC)

    Time frame: Part A: Every 2 months; Part B: after 1 month and every two cycles thereafter

    FAS : For both Parts A and B. Objective response rate is defined as the number of patients with overall best response of complete response (CR) or partial response (PR)
