Brief Title
Study of D07001-Softgel Capsules in Subjects With Gastrointestinal Cancer in Dose-Escalation Phase and in Subjects With Biliary Tract Cancer in Dose-Expansion Phase
Official Title
Open-Label, Multicenter Study of D07001-Softgel Capsules (Oral Gemcitabine Hydrochloride) in Subjects With Unresectable, Metastatic or Locally Advanced Gastrointestinal (GI) Cancer in Dose-Escalation Phase and in Subjects With Advanced Biliary Tract Cancer (BTC) Following Primary Chemotherapy or Combined Chemoradiotherapy (CCRT) in Dose-Expansion Phase
Brief Summary
Part 1: Dose-Escalation Phase (Phase 1b) The primary objective is to assess the safety and
tolerability of increasing doses of D07001 softgel in patients with unresectable locally
advanced or metastatic gastrointestinal (GI) cancer.
Part 2: Dose-Expansion Phase (Phase 2) The primary objective is to assess the safety and
tolerability of D07001 softgel in patients who have achieved stable disease or better
following first line chemotherapy or combined chemoradiotherapy (CCRT) for unresectable
metastatic or locally advanced biliary tract cancer (BTC)
Detailed Description
This open label, multicenter study will be conducted in 2 parts: a dose-escalation phase
(Part 1) and a dose-expansion phase (Part 2).
In both Part 1 and Part 2, eligible patients will be assigned to receive oral D07001-softgel
on Days 1, 3, 5, 8, 10, 12, 15, 17, and 19 of a 21-day cycle (9 doses per cycle).
Part 1: Dose Escalation Phase (Phase 1b) Part 1 of the study will follow a 3+3 dose
escalation scheme at predefined dose levels. There will be sequential cohorts of 3 to 6
patients each with increasing doses of 40 mg, 60 mg, 80 mg, 120 mg, and 160 mg per cohort.
There will be no intra patient dose escalation. Cycle 1 (21 days) is defined as the dose
limiting toxicity (DLT) assessment period.
Part 2: Dose Expansion Phase (Phase 2) In Part 2 of the study, eligible patients will be
randomized in a 1:1 ratio to receive D07001-softgel in an open label manner at 1 of the 2
dose levels selected for expansion. Twenty (20) patients will be enrolled to each dose
expansion cohort. Patients will be treated until withdrawal from treatment due to disease
progression according to RECIST v1.1, withdrawn consent, or when another treatment
discontinuation criterion is met. Patients who are discontinued from study drug for reasons
other than disease progression or toxicity in the first 2 cycles of Part 2 will be replaced.

Eligibility Criteria
Inclusion Criteria:
1. Provision of a signed and dated written Informed Consent Form (ICF) prior to any study
specific procedures
2. Male or female patients aged 18 years or older at screening (aged 20 years or older in
Taiwan)
3. Histopathological or cytologic diagnosis of unresectable, metastatic or locally
advanced GI cancer (Part 1) or unresectable metastatic or locally advanced BTC
(cholangiocarcinoma or gallbladder cancer; Part 2)
4. Part 1 only: Refractory to or have relapsed from all standard therapies of advanced GI
malignancy
5. Part 2 only:
1. Achieved stable disease or better, based on the Investigator's assessment, in
response to first line systemic therapy or CCRT, with continued stable disease or
better based on imaging studies obtained as part of screening
2. Completed first line systemic therapy (with 2-8 cycles of chemotherapy with a
gemcitabine based regimen) or CCRT, based on the local standard of care and
preferences in the participating countries Note: No more than 30% of patients
enrolled in Part 2 will have received CCRT
6. No more than 60 days have elapsed between completion of the prior line of chemotherapy
or CCRT and enrollment
7. Part 2 only: Patient has not received intervening systemic therapy since first line
treatment
8. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0-2 in Part 1 and
0-1 in Part 2
9. Life expectancy is >12 weeks
10. Adequate bone marrow function, demonstrated by:
1. Absolute neutrophil count (ANC) ≥1,500 cell/mm3
2. Platelet count ≥100,000 cells/mm3
3. Hemoglobin ≥9 g/dL
11. Adequate liver function, demonstrated by:
1. Aspartate transaminase (AST) and alanine transaminase (ALT) ≤2.5 x upper limit of
normal (ULN), or ≤5.0 x ULN in the case of liver metastases
