Study Description

Brief Summary:

This is a multi-center, open-label, dose escalation study to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and maximum tolerated dose (MTD) of QBS10072S in patients with advanced or metastatic cancers with high LAT1 expression. The MTD of QBS10072S will be confirmed in patients with relapsed or refractory grade 4 astrocytoma.

Condition or disease	Intervention/treatment	Phase
Astrocytoma; Brain Cancer; Brain Metastases; Bladder Cancer; Breast Cancer; Cervical Cancer; Cholangiocarcinoma; Colorectal Cancer; Esophagus Cancer; Gastric Cancer; Head and Neck Cancer; Kidney Cancer; Liver Cancer; Lung Cancer; Melanoma; Ovarian Cancer; Pancreatic Cancer; Pleural Mesothelioma; Prostate Cancer; Sarcoma; Tongue Cancer; Thymic Carcinoma; Urinary Tract Cancer	Drug: QBS10072S	Phase 1

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 15 participants
• Allocation: N/A
• Intervention Model: Sequential Assignment
• Intervention Model Description: The dose escalation scheme for this trial employs an mTPI-2 design.
• Masking: None (Open Label)
• Primary Purpose: Treatment
• Official Title: A Phase 1, Open Label, Multi-Center, Single and Multiple Dose, Dose Escalation and Expansion Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of QBS10072S in Previously Treated Patients With Advanced or Metastatic Cancers With High LAT1 Signatures, and in Patients With Relapsed or Refractory Grade 4 Astrocytoma
• Actual Study Start Date: July 20, 2020
• Actual Primary Completion Date: September 21, 2022
• Actual Study Completion Date: December 22, 2022

Arms and Interventions

Arm	Intervention/treatment
Experimental: Dose escalation of QBS10072S; Intravenous administration of QBS10072S once every 4 weeks starting at 3mg/m2 and increasing dose levels in subsequent cohorts.	Drug: QBS10072S; QBS10072S targets cancers with high LAT1 expression.

Outcome Measures

Primary Outcome Measures :

1. Determination of maximum tolerated dose (MTD) [ Time Frame: 28 days ]
   MTD will be determined by presence of AEs as characterized by type, severity (as graded by NCI CTCAE version 5.0), timing, seriousness, and relationship to study therapy.

Secondary Outcome Measures :

1. Safety and tolerability assessed by adverse events and serious adverse events [ Time Frame: 28 days ]
   Safety and tolerability will be determined by adverse events as characterized by type, severity (as graded by NCI CTCAE version 5.0), timing, seriousness, and relationship to study therapy.
2. Peak Plasma Concentration (Cmax) [ Time Frame: 28 days ]
   Determine the maximum plasma concentration of QBS10072S.
3. Area under the plasma concentration versus time curve (AUC) of QBS10072S [ Time Frame: 28 days ]
   Determine the plasma concentration of QBS10072S over time.
4. Half-life of QBS10072S in plasma (t1/2) [ Time Frame: 28 days ]
   Determine the half life of QBS10072S in plasma; the half-life of a drug is the time taken for the plasma concentration of a drug to reduce to half its original value.
5. Time to maximum concentration of QBS10072S in plasma (Tmax) [ Time Frame: 28 days ]
   Determine the time it takes to achieve maximum concentration of QBS10072S in plasma.

Eligibility Criteria

2. Adequate Bone Marrow Function
3. Adequate renal function
4. Adequate Liver Function
5. Resolved acute effects of any prior therapy to baseline severity or CTCAE Grade ≤1 except for AEs not constituting a safety risk by Investigator judgment.

6. A histological or cytological diagnosis of a solid tumor that is advanced/metastatic, patients intolerant to standard treatment or, resistant to standard therapy* (per NCCN guidelines) or for which no curative therapy is available for the following tumor types:

   - Bladder, Brain, Breast, Cervical, Cholangiocarcinoma, Colorectal, Esophageal, Gastric, Head and Neck, Kidney, Liver, Lung, Melanoma, Ovarian, Pancreatic, Pleural mesothelioma, Prostate, Sarcoma, Tongue cancer, Thymic carcinomas, Urinary tract

8. An ECOG PS 0 to 2.

Exclusion Criteria:

1. Patients with tumor primarily localized to the brainstem or spinal cord. Presence of known active uncontrolled or symptomatic CNS metastases, carcinomatous meningitis, or leptomeningeal disease as indicated by clinical symptoms, cerebral edema, and/or progressive growth.
2. Patients with advanced/metastatic, symptomatic, visceral spread, that are at risk of life-threatening complications in the short term (including patients with massive uncontrolled effusions [pleural, pericardial, peritoneal], pulmonary lymphangitis, and over 50% liver involvement).

7. Bleeding esophageal or gastric varices <2 months prior to the date of informed consent.
8. Unmanageable ascites.
9. Baseline 12 lead ECG that demonstrates clinically relevant abnormalities that may affect patient safety or interpretation of study results
