Brief Title
A Phase I/II Safety and Efficacy Study of PCI of Gemcitabine and Chemotherapy in Patients With Cholangiocarcinomas
Official Title
A Phase I/II Dose Escalation Study to Assess the Safety, Tolerability and Efficacy of Amphinex®-Induced Photochemical Internalisation (PCI) of Gemcitabine in Patients With Advanced Inoperable Cholangiocarcinomas
Brief Summary
This is a Phase I Dose Escalation Study in which the safety, tolerability and efficacy of
Amphinex®--induced Photochemical Internalisation (PCI) of Gemcitabine followed by
Gemcitabine/Cisplatin Chemotherapy will be assessed in patients with advanced inoperable
cholangiocarcinomas.
Detailed Description
Cholangiocarcinoma (CCA) is an uncommon adenocarcinoma arising from the neoplastic
transformation of cholangiocytes, the epithelial cells lining the intra-hepatic and
extra-hepatic bile ducts. CCA accounts for about 3% of all digestive tumours and 10-15% of
the hepatobiliary tumours. It has an annual incidence of 1-2 cases per 100,000 in the Western
World, but rates of CCA have been steadily rising worldwide over the past several decades. On
a global scale, CCA is the second most common primary hepatic malignancy These tumours have a
poor overall survival with a 5-year survival of about 5%. Over 50% of patients present with
advanced-stage disease, and the prognosis is poor with the survival of between 6-12 months
for unresected patients, even after biliary decompression. CCA may arise anywhere in the
biliary tree, from the small, peripheral hepatic ducts to the distal common bile duct.
Commonly used classification systems utilise anatomical location to group tumours into three
main categories: intra-hepatic (20-25%), perihilar (also including hilar/Klatskin tumour -
50%) and distal (20-25%).
Hilar CCA is an adenocarcinoma of the extrahepatic biliary tree arising from the main left or
right hepatic ducts or their confluence. There has a been a growing recognition that hilar
CCA disease actually has a distinct biological behaviour and natural history compared to that
of (distal) extra-hepatic CCA, and increasing acknowledgment that different therapeutic
strategies are required. At initial presentation of patients with extra-hepatic CCA, 30-50%
will have local lymph node involvement and 10-20% metastatic spread typically to the liver
and peritoneum. With hilar CCA due to the long asymptomatic course, only 20% are resectable
at time of diagnosis.
Standard treatment options for CCA include surgery, radiotherapy and chemotherapy, dependent
upon if the CCA is intra- or extra-hepatic. Tumour resection is the only potential cure for
CCA. Recent advances in transplantation using stringent selection criteria and utilization of
neoadjuvant chemoradiation have demonstrated encouraging results with 5 year survival rates
of over 70%, with even one series from The Mayo Clinic yielding a 5-year survival rate of
82%. For the 80% who present with unresectable disease, the utility of these modalities
combined with biliary decompression interventions only provided a median survival time of 3-6
months from the time of diagnosis.
For these patients with inoperable advanced CCA the main treatment aim is palliative to
relieve local symptoms such as pain and jaundice. Surgery for these patients is primarily for
creating a bypass in patients who cannot be stented. CCA is remarkably resistant to
pharmacological therapy, but activity has been seen using chemotherapy; mainly gemcitabine
given either as monotherapy or paired with either a platin derivative or a fluoropyrimidine
as a doublet treatment and more recently docetaxel, these give partial response (PR) rates of
0-9% and an average survival advantage of 2-12 months. Concerning biological therapy, the
ongoing studies using sorafenib, lapatinib or bevacizumab have yielded some promising
results, with sorafenib demonstrating therapeutic benefit in a single arm Phase II study. For
patients who are unsuitable for curative resection, the current systemic combination
chemotherapy is with cisplatin plus gemcitabine. This was established in the largest
randomized phase III study to date in non-operable biliary tract cancer which demonstrated a
response rate of 81.4% and a median overall survival (OS) of 11.7 months; notably there was
no statistically significant increase in toxicity when compared to gemcitabine monotherapy.
The recent advances in interventional and endoscopic technology have seen a rise in highly
specialized centres that are able to deliver very precise local control treatments aimed at
gaining local control; these include local ablation and embolization, brachytherapy,
radio-frequency ablation and, most significantly, photodynamic therapy which (PDT), with its
favourable adverse-event profile, is recommended by most recent review articles for
non-resectable patients.

Phase I
Description: Experimental PCI treatment in dose escalation cohorts consist of Amphinex injection (at different doses) plus a single standard dose of Gemcitabine (1000 mg/m2) plus intraluminal light at the tumour area (at different doses). In addition up to 8 cycles of standard chemotherapy doses of Gemcitabine (1000 mg/m2) and Cisplatin (25 mg/m2) was provided. In the Extended part of the study (last cohort) an additional PCI treatment was introduced at Cycle 5 in the treatment Schedule.
