Brief Summary:
To determine the maximum tolerated dose (MTD) based on the safety and tolerability after single-dose administration of PN-101 in patients with refractory polymyositis or dermatomyositis. To explore the efficacy after single-dose administration of PN-101 in patients with refractory polymyositis or dermatomyositis.

Condition or disease Intervention/treatment Phase
Polymyositis Dermatomyositis Biological: PN-101 Phase 1 Phase 2

Detailed Description:

This Phase 1/2a clinical trial involves patients diagnosed with refractory polymyositis or dermatomyositis.

The initial safety assessment is conducted, including development of DLT in subjects up to Week 2 after the investigational product administration.

[DLT assessment criteria and method]

  • Low dose or intermediate dose level

    1. No DLT developing in the initially enrolled 3 subjects (0/3): Increase the dose to the next dose group
    2. DLT developing 1 of 3 subjects (1/3): Enroll 3 additional subjects at the same dose group and then assess DLT, and ① DLT developing in 1 out of total 6 subjects (1/3+0/3; 1/6): Increase the dose to the next dose group ② DLT developing in ≥ 2 out of total 6 subjects (≥ 2/6): In case of the low dose level, the trial is discontinued without MTD determination. In case of the intermediate dose level, MTD is assessed at the low dose which is a one lower dose level
  • High dose level

    1. No DLT developing in the initially enrolled 3 subjects (0/3): Declare as the MTD
    2. DLT developing 1 of 3 subjects (1/3): Enroll 3 additional subjects at the same dose group and then assess DLT, and ① DLT developing in 1 out of total 6 subjects (1/3+0/3; 1/6): Declare as the MTD ② DLT developing in ≥ 2 out of total 6 subjects (≥ 2/6): Assess MTD at the intermediate dose which is the one lower dose level

  2. International Myositis And Clinical Studies group-Total Improvement Score(IMACS-TIS) [ Time Frame: 8 weeks after the IP administration ]
    Assessment of IMACS-TIS at week 8 after the IP administration. Total Improvement Score (TIS) based on absolute percentage change is assessed scale 0 to 100. Higher score indicates greater improvement.

  3. Response rate of IMACS-TIS [ Time Frame: 12 weeks after the IP administration ]
    Proportion of subjects with the IMACS-TIS ≥ 20 at week 12 after the IP administration.

  4. Changes of Core Set Activity Measures(CSAM) [ Time Frame: Visit 2(Day 1), Visit 5(4 weeks), Visit 6(8 weeks), Visit 7(12 weeks) ]
    Changes in CSAM for the IMACS assessed at week 4, week 8 and week 12 after the IP administration from the baseline (Visit 2).

  5. Changes of Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) [ Time Frame: Visit 2(Day 1), Visit 5(4 weeks), Visit 6(8 weeks), Visit 7(12 weeks) ]
    Changes in CDASI assessed at week 4, week 8 and week 12 after the IP administration from the baseline (Visit 2) for dermatomyositis only.

  6. Changes of Peak Pruritus Numeral Rating Scale(PPNRS) [ Time Frame: Visit 2(Day 1), Visit 5(4 weeks), Visit 6(8 weeks), Visit 7(12 weeks) ]
    Changes in PPNRS assessed at week 4, week 8 and week 12 after the IP administration from the baseline (Visit 2) for dermatomyositis only. The intensity of pruritis is assessed on a patient reported scale 0 to 10.
