Investigating Tigilanol Tiglate for Soft Tissue Sarcoma Treatment

A Phase IIa Open Label Study Evaluating the Preliminary Efficacy of Intratumoural Tigilanol Tiglate in Advanced and/or Metastatic Soft Tissue Sarcoma of the Extremities and Body Wall.

This study is testing if a new treatment called tigilanol tiglate can help shrink tumors and control disease in people with advanced soft tissue sarcoma in their arms or legs.

What this trial studies

This Phase IIa open-label study evaluates the efficacy of intratumoral tigilanol tiglate in patients with advanced or metastatic soft tissue sarcoma located in the extremities and body wall. The primary objectives include assessing tumor ablation and overall disease control following treatment. Secondary objectives focus on the safety and tolerability of the treatment, as well as pharmacokinetic assessments. Additionally, exploratory objectives aim to evaluate the tumor microenvironment, immune response, local recurrence rates, and metabolites post-treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced or metastatic soft tissue sarcoma that can be treated with intratumoral injections.

Not a fit: Patients with non-advanced soft tissue sarcoma or those who cannot undergo intratumoral injections may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced soft tissue sarcoma.

How similar studies have performed: Other studies have shown promise with similar intratumoral therapies, suggesting potential for success in this approach.

Eligibility criteria

Inclusion Criteria:

1. Are willing and able to provide written informed consent for the study prior to any protocol-specific procedures and to comply with all local and study requirements.
2. Are ≥ 18 years of age on the day of providing informed consent.
3. Have advanced and/or metastatic disease of the body wall or extremities that is amenable to intratumoural injection either by palpation or under ultrasound guided injection, that has been histologically or pathologically confirmed as an STS. STS located on the scalp may also be considered for treatment.
4. Have an Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2.
5. Have life expectancy of more than 12 weeks.
6. Have adequate renal and hepatic function as assessed by the Investigator.
7. Female participants who are Women Of Child-Bearing Potential (WOCBP) must have a negative serum pregnancy test at Screening (within 14 days of the first study drug administration), must be willing to use a highly effective contraception from date of consent, throughout the study period and up to 30 days after the last study drug administration, and must not be breastfeeding.
8. Male participants with a potentially fertile female partner are eligible if they have had a vasectomy or are willing to use adequate contraception from prior to commencement of study drug administration, throughout the study period and up to 30 days after the last study drug administration, and must not donate sperm throughout the study period and up to 30 days after the last study drug administration.

Exclusion Criteria:

1. Are planning to receive intratumoural treatment or radiotherapy to any of the tumours intended for injection within 28 days prior to Screening, or during treatment with tigilanol tiglate.
2. Have a tumour intended for injection that is immediately adjacent to, or with infiltration into, any major artery or vein (e.g., if the tumour for injection is located adjacent to the jugular vein).
3. Are receiving or have received other investigational agents or have used an investigational device without undergoing a 28-day (or 5 half-lives, whichever is shorter) wash-out period prior to their first treatment with tigilanol tiglate. These patients must have recovered from all AEs due to previous investigational therapies to ≤ Grade 1 at baseline.
4. Are receiving or have received systemic anticancer therapy, without undergoing a 28-day (or 5 half-lives, whichever is shorter) wash-out period prior to their first treatment with tigilanol tiglate. These patients must have recovered from all AEs due to previous therapies to ≤ Grade 1 at baseline. Patients with ≤ Grade 2 neuropathy may be eligible following discussion with Sponsor Medical Monitor.
5. Have had major surgery within 28 days of their first treatment with tigilanol tiglate or anticipate the need for major surgery during the study period. Minor surgical procedures are permitted, but with sufficient time for wound healing.
6. Have known, active brain metastases and/or carcinomatous meningitis. Participants who have previously treated brain metastases and are neurologically stable can be included.
7. Have any bleeding diathesis or coagulopathy that would make intratumoural injection or biopsy unsafe, or if they are on therapeutic warfarin therapy.
8. Have a history of allergic reactions or severe hypersensitivity (Grade ≥ 3) attributed to tigilanol tiglate or compounds of similar chemical or biologic composition to tigilanol tiglate, any of its excipients or other agents used in the study.
9. In the opinion of the treating Investigator, they are not an appropriate candidate for the study for any reason (e.g., they have known psychiatric or substance abuse disorder that would interfere with their ability to cooperate with the requirements of the study.
