A Phase 1 Study to Assess the Immunogenicity of QL0605 Compared to US Neulasta in Healthy Subjects

A Randomized, Double-blind, 2-period Parallel-arm Study to Assess the Immunogenicity of 2 Subcutaneous Doses of QL0605 (6 mg) Compared to 2 Subcutaneous Doses of US Neulasta P®P (6 mg) in Healthy Male and Female Subjects

The study was an assessor-blind, balanced, parallel, randomized, two-treatment, comparative immunogenicity study of multiple doses of subcutaneous (SC) Pegfilgrastim injection (6 mg/0.6 mL; Qilu Pharmaceutical Co., Ltd. proposed biosimilar QL0605 compared to innovator product, US-Neulasta) in healthy, adult, human subjects.

Study Overview

• Status: Unknown
• Conditions: Healthy
• Intervention / Treatment: Drug: QL0605; Drug: US Neulasta

Detailed Description

This is a multi-center, randomized, double-blind, single-dose, 2-period parallel-arm study designed to assess the immunogenicity of QL0605 and US-Neulasta.

A total of 300 healthy male and female subjects aged 18-55 years (inclusive) will be included and randomized to receive either 2 s.c. doses of QL0605 or US-NeulastaP®P in a ratio of 1:1. After the Screening Period of up to 4 weeks the subject will be randomly allocated to one of the 2 parallel treatment arms. All subjects will receive 1 s.c. injection of 6 mg QL0605 or 6 mg NeulastaP®P (US) in Treatment Period 1 and 1 s.c. injection of 6 mg QL0605 or 6 mg NeulastaP®P in Treatment Period 2. The interval between doses is ≥ 42 days.

• Accepts Healthy Volunteers: Yes
• Genders Eligible for Study: All

Description

Inclusion Criteria:

1. Subjects must give written informed consent before any assessment is performed;
2. Subjects must be a healthy male or female aged 18 to 55 years (both inclusive) at the time of informed consent;
3. Body weight ≥60 kg (males) or ≥50 kg (females) at the Screening Visit;
4. The Body Mass Index (BMI) between 18.5 to 29.9 kg/m2 (inclusive) at the Screening Visit (BMI = Body weight (kg)/[Height (m)]2);
5. Absolute neutrophil count and total leukocyte count are within the normal laboratory reference ranges; platelet count, hematocrit, and haemoglobin results are not below the lower limit of laboratory reference ranges; reticulocyte count is not above the upper limit of laboratory reference ranges; all other laboratory parameters within reference ranges or showing no clinically relevant deviations as judged by the Investigator. If the results of the laboratory parameters (other than total leukocyte count, platelet count, neutrophil count, hematocrit, reticulocyte count and hemoglobin) are outside the normal reference ranges, the subject may be included only if the Investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate for the population under study;

6. Female subjects must either be:

   • of non-childbearing potential:

     • Postmenopausal (defined as at least 1 year without any menses) prior to the Screening Visit, and the follicle stimulating hormone levels indicative of menopause according to local laboratory reference ranges at Screening, or
     • Documented permanent surgically sterile (hysterectomy, bilateral salpingectomy and bilateral oophorectomy) since at least 6 weeks before the Screening Visit

   • or, if of childbearing potential:

     • Agree not to try to become pregnant during the clinical study and for 49 days after the last IMP administration and
     • Must have a negative serum pregnancy test at screening and

     • If heterosexually active, agree to consistently use 2 forms of birth control (1 of which is a highly effective method† and 1 must be a barrier method‡) from screening and throughout the study period, and for 49 days after last IMP administration. The highly effective method of contraception should be stable for at least 28 days prior to first IMP administration.

       • Highly effective forms of birth control include (i.e., less than 1% failure rate per year when used consistently and correctly):
   • Consistent and correct usage of established oral contraception (this is considered highly effective, because it is used in combination with a barrier method)
   • Injected or implanted hormonal methods of contraception
   • Established (with a failure rate < 1%) intrauterine device (IUD) or intrauterine system (IUS)
   • Bilateral tubal ligation
   • Any male partner that has undergone effective surgical sterilization, provided that the partner is the sole sexual partner of the female study participant

   • Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments and complies with the preferred and usual lifestyle of the subject.

     ‡ Barrier methods of birth control include for males and females:

   • Condom without spermicidal foam/gel/film/cream/suppository or fat- or oil containing lubricant.
   • Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository.
7. Female subjects must agree not to breastfeed starting at the Screening Visit and throughout the clinical study period, and for 49 days after last IMP administration;
8. Female subjects must not donate ova starting at the Screening Visit and throughout the clinical study period, until the final Follow-up Visit;
9. Male subjects and their female spouse/partners who are of childbearing potential must be using 2 forms of birth control (1 of which is a highly effective method† and 1 must be a barrier method‡) starting at the Screening Visit and throughout the study period and for 49 days after the last IMP administration. A condom is required to be used also by vasectomized men to prevent delivery of the drug via seminal fluid;
10. Subjects must be non-smoker, or light smokers who smoke not more than 5 cigarettes or 1 cigar or 1 pipe per day and who agree to abstain from smoking while resident at the clinical unit.
