Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of TGW101 in Participants With Advanced Solid Tumors

Summary

The primary objectives of this study are to evaluate the safety and tolerability of TGW101 and determine the recommended dosing regimen(s) for further study. The secondary objectives are to assess pharmacokinetics and preliminary antitumor activity.

Eligibility

   1. Breast cancer (all subtypes).
   2. Castrate-resistant prostate cancer.
   3. Cervical cancer.
   4. Endometrial cancer.
   5. Esophageal, adenocarcinoma only.
   6. Gastric/gastroesophageal junction (GEJ).
   7. Non-squamous cell carcinoma of the head and neck, e.g., salivary gland neoplasms, with the exception of adenoid cystic carcinoma.
   8. Non-small cell lung cancer, adenocarcinoma only.
   9. Ovarian.
4. Refractory disease, intolerance to, or documented refusal of available standard therapy(ies) known to provide clinical benefit for the participant's solid tumor malignancy per Investigator judgment.
5. At least 1 measurable lesion per RECIST v1.1 except for participants with bone-only metastatic disease.
6. Biopsy pretreatment; if not possible, archival tissue block (preferred) or unstained formalin-fixed paraffin-embedded slides required.

2. Known symptomatic brain metastases.
3. Significant cardiovascular disease within 6 months prior to starting study drug.
4. Evidence of an active systemic bacterial, fungal, or viral infection requiring treatment.
5. Grade ≥ 2 peripheral neuropathy.
6. Major surgery within 4 weeks prior to starting study drug.
7. Prior solid organ or bone marrow progenitor cell transplantation.
8. Prior high-dose chemotherapy requiring stem cell rescue.
9. Anticancer therapy within 28 days or within 5 half-lives (whichever is shorter) prior to starting study drug.
