Phase I Clinical Study on the Safety, Tolerability, and Pharmacokinetics of Recombinant Human nsIL12 Oncolytic Adenovirus Injection (BioTTT001) in Patients With Malignant Solid Tumors

This is a Phase 1 open-label study to evaluate the safety, tolerability, and pharmacokinetics of Recombinant Human nsIL12 Oncolytic Adenovirus Injection (BioTTT001) at dose of 5×10∧9VP、5×10∧10VP、5×10∧11VP in Patients With Malignant Solid Tumors. Subjects will be treated with a single dose of BioTTT001 Injection after the screening period.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a single arm, open label, single center dose escalation trial. Three study drug dosage groups are pre-set, namely 5 × 10∧9VP、5 × 10∧10VP、 5 × 10∧11VP. According to the principle of dose escalation from low to high, the "3+3" dose escalation method is adopted. In theory, in order to protect the safety of the subjects, during the DLT observation phase of the same dose group, the first subject in each dose group can only be enrolled in the second subject after at least 2 weeks after administration. The DLT observation period for each subject is 28 days after the first administration, and the last subject in each dose group can only enter the next dose escalation after completing the DLT observation period. At least 3 subjects are enrolled in each dose group, and each subject only receives one corresponding dose.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age range from 18 to 80 years old (including the threshold), no gender restrictions.
  2. Patients with histologically and/or cytologically confirmed malignant solid tumors, who have experienced at least one-line standard treatment failure or intolerance, or lack standard treatment options. Focus on malignancies in the head and neck, colorectal cancer, skin malignancies, and cervical cancer.
  3. At least one assessable lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
  4. Assessed by the investigators to have lesions suitable for intratumoral injection (assessable lesions and intratumoral injection lesions can refer to the same lesion).

Exclusion Criteria:

  1. Known allergy to the investigational drug or its components.
  2. Previous treatment with other adenovirus drugs.
  3. Patients with active autoimmune diseases (such as systemic lupus erythematosus, rheumatoid arthritis, etc.), except type 1 diabetes, hypothyroidism that only needs hormone replacement therapy, and skin diseases that do not need systemic treatment (such as vitiligo, psoriasis or alopecia).
  4. Patients who have not recovered from the adverse reactions of previous treatments (the treatment-related toxicity ≤ grade 2, except for alopecia, pigmentation or other tolerable events judged by the investigator ).
