4. Subjects with known active hepatitis B or C infection, or hepatobiliary disease, or known history of immunodeficiency virus infection (However, subjects with Gilbert's Syndrome, asymptomatic gallstones, or stable chronic liver disease are, at the discretion of the investigator, eligible for the study. Subjects who are hepatitis B carriers may be eligible if they are on antiviral therapy 2 weeks prior to study entry).

5. Subjects with neuropathy grade > 2 based on CTCAE v5.0 at the time of study entry.

6. Subjects with uncontrolled medical or mental illness that, in the investigator's judgement, could affect treatment tolerability or compliance.

7. Subjects diagnosed with other malignant primary tumor with an exception of the following:

   • Malignancy diagnosed at least 5 years previously without evidence of recurrence or persistent disease
   • The complete excision of basal/squamous cell carcinoma or papillary thyroid carcinoma or the complete treatment of cervical intraepithelial neoplasia or other in situ carcinoma

8. Subjects with symptomatic or unstable, untreated metastases to the central nervous system (CNS) at the time of screening ('Unstable' means worsening of symptoms within 4 weeks prior to screening).

9. Subjects who are currently receiving alternative cytotoxic agents, regular systemic corticosteroids and medications that could influence drug absorption (e.g. H2-antihistamines, antacids, metoclopramide and charcoal) within 4 weeks prior to entry into the study (C1D1).

10. Subjects who are currently receiving (or unable to stop use the 3 days before the first dose of DHP107 and throughout the study) prescription or non-prescription medications or other products known to be moderate or potent inhibitors/inducers of CYP3A4, P-gp, or CYP2C8.

11. Subjects who cannot intake whole high fat meal offered.
