First-in-human Study of Oral TP-0903 (a Novel Inhibitor of AXL Kinase) in Patients With Advanced Solid Tumors

Are you eligible to participate in this study?

You may be eligible for this study if you meet the following criteria:

  • Conditions: Advanced Solid Tumors | BRAF-Mutated Melanoma | Recurrent Ovarian Carcinoma | Colorectal Cancer | EGFR Positive Non-small Cell Lung Cancer
  • Age: Between 18 - 100 Years
  • Gender: Male or Female

Inclusion Criteria:

To be eligible for participation in the study, patients must meet all of the following inclusion criteria:

  1. Patients enrolled in the Phase 1a study must:
  2. Have a histologically confirmed diagnosis of advanced metastatic or progressive solid tumor
  3. Be refractory to, or intolerant of, established therapy known to provide clinical benefit for their condition
  4. Patients enrolled in the Phase 1b study must meet criteria for one of the following tumor types:
  5. Have tumors that have progressed after achieving a best documented response of at least stable disease (ie, SD, PR, or CR documented per iRECIST following at least 2 cycles (8 weeks) of immunotherapy and are felt to be appropriate for this type of treatment*
  6. Have EGFR+ NSCLC and have demonstrated recent progression following a best documented response of at least stable disease (ie, SD, PR, or CR documented per per RECIST v1.1 on 2 lines of oral TKIs and are felt to be appropriate for this type of treatment* Prior chemotherapy immunotherapy is allowed as long as the patient is clearly demonstrating current progression on an EGFR TKI.
  7. Have BRAF-, KRAS-, or NRAS-mutated CRC for whom there is no standard therapy remaining
  8. Have persistent/recurrent ovarian cancer who would be platinum refractory/ resistant and have had any number of lines of prior therapy
  9. Have BRAF-mutated melanoma that has not responded to immunotherapy or a combination BRAF/MEK inhibitor
  10. Have one or more tumors measurable or evaluable as outlined by modified RECIST v1.1 or iRECIST
  11. Have an Eastern Cooperative Oncology Group (ECOG) (World Health Organization [WHO]) performance of 1
  12. Have a life expectancy 3 months
  13. Be 18 years of age
  14. Have a negative pregnancy test (if female of childbearing potential)
  15. Have acceptable liver function:
  16. Bilirubin 1.5x upper limit of normal (ULN)

*Patients receiving immunotherapy should have a bilirubin level <3.0x ULN.

2. Aspartate aminotransferase (AST/SGOT), alanine aminotransferase (ALT/SGPT) and alkaline phosphatase 2.5x upper limit of normal (ULN)

  • If liver metastases are present, then 5x ULN is allowed.
  • Patients receiving immunotherapy should have AST and ALT levels <5.0x ULN. 9. Have acceptable renal function:
    1. Calculated creatinine clearance 30 mL/min
    2. Have acceptable hematologic status:
    3. Granulocyte 1500 cells/mm3
    4. Platelet count 100,000 (plt/mm3)
    5. Hemoglobin 9 g/dL
    6. Have no clinically significant abnormalities on urinalysis
    7. Have acceptable coagulation status:
    8. Prothrombin time (PT) within 1.5x normal limits
    9. Activated partial thromboplastin time (aPTT) within 1.5x normal limits
    10. Be nonfertile or agree to use an adequate method of contraception. Sexually active patients and their partners must use an effective method of contraception (hormonal or barrier method of birth control; or abstinence) prior to study entry and for the duration of study participation and for at least 30 days after the last study drug dose (see Section 4.6.3). Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
    11. Have read and signed the IRB-approved informed consent form prior to any study related procedure. (In the event that the patient is re-screened for study participation or a protocol amendment alters the care of an ongoing patient, a new informed consent form must be signed.)
    12. Patients enrolled in each of the five Expansion Cohorts must be willing to consider pre-study and on-study biopsies, if safe and medically feasible, as determined by local interventional radiology (3 to 5 core samples requested at each biopsy timepoint)

Patients meeting any one of these exclusion criteria will be prohibited from participating in this study:

  1. Have New York Heart Association (NYHA) Class III or IV, cardiac disease, myocardial infarction within the past 6 months prior to Day 1, unstable arrhythmia, or evidence of ischemia on electrocardiogram (ECG) or during Cardiac Stress Testing within 14 days prior to Day 1 (Appendix C)
  2. Have a corrected QT interval (QTcF, Fridericia's method) of >450 msec in men and >470 msec in women
  3. Have a seizure disorders requiring anticonvulsant therapy
  4. Presence of symptomatic central nervous system metastatic disease or disease that requires local therapy such as radiotherapy, surgery, or increasing dose of steroids within 2 weeks prior to Day 1
  5. Have severe chronic obstructive pulmonary disease with hypoxemia (defined as resting O2 saturation of 88% breathing room air)
  6. Have undergone major surgery, other than diagnostic surgery, within 2 weeks prior to Day 1
  7. Have active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy
  8. Are pregnant or nursing
  9. Received treatment with radiation therapy, surgery, chemotherapy, or investigational therapy within 28 days or 5 half lives, whichever occurs first, prior to study entry (6 weeks for nitrosoureas or Mitomycin C)
  10. This exclusion criterion is not applicable for patients with EGFR+ NSCLC or immunotherapy-resistant tumors who are enrolled in expansion cohorts at the MTD.
  11. Are unwilling or unable to comply with procedures required in this protocol
  12. Have known infection with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C. Patients with history of chronic hepatitis that is currently not active are eligible
  13. Have a serious nonmalignant disease (eg, hydronephrosis, liver failure, or other conditions) that could compromise protocol objectives in the opinion of the investigator and/or the sponsor
  14. Are currently receiving any other investigational agent
  15. Have exhibited allergic reactions to a similar structural compound, biological agent, or formulation
  16. Have undergone significant surgery to the gastrointestinal tract that could impair absorption or that could result in short bowel syndrome with diarrhea due to malabsorption
  17. Have a history of severe adverse reaction (eg, hypersensitivity reaction, anaphylaxis) to sulfonamides
  18. Patients scheduled to receive immunotherapy or TKI regimens plus TP-0903 must not be currently taking high-dose steroids (ie, physiologic dose approximately equivalent to 15 mg/day of prednisone)
