AHCC Completed Studies

AHCC08	Hepatocellular Carcinoma Registry in Asia (Clinicaltrials.gov Identifier: NCT03233360)
Funding	Industry (IQVIA)
Period	17 Apr 2017 to 31 Dec 2020
Status	Completed recruitment of 2,533 patients in December 2019. Preliminary results presented at ASCO 2018, ILCA (2018), ASCO GI (2019) and APPLE (2019). Publication in progress
Abstract	Previous studies contributed considerably to the knowledge of the HCC epidemiology, but there are significant limitations. These data do not represent real world data as these are from randomized controlled trials and case series from tertiary clinical centers. Real world data on the presentation, clinical trajectory and management of HCC in the Asia-Pacific must be prospectively collected on the ground in order to develop effective public health strategies and provide direction to the development of therapeutics. This investigator-initiated multi-site longitudinal cohort study includes newly diagnosed HCC patients between 2013 and 2019 in Asia-Pacific. Patients to be treated, managed and followed up according to local clinical practice. Data collection are aligned with patients’ routine visit. Patient-reported outcome (PRO) to be collected using paper questionnaires at each patients’ routine visit. Planned sample size is 2,500 patients from 9 countries.

AHCC06	Phase III Multi-Centre Open-Label Randomized Controlled Trial of Selective Internal Radiation Therapy (SIRT) Versus Sorafenib in Locally Advanced Hepatocellular Carcinoma (SIRveNIB) (Clinicaltrials.gov identifier: NCT01135056)
Funding	NMRC CSA 2010, NMRC IAF CAT 1 and Industry (Sirtex)
Period	1 May 2010 to 28 Jul 2018
Status	Completed recruitment of 360 patients in July 2018. Results were presented at ASCO Annual Meeting (2017) on 4 June 2017, APPLE Meeting (Singapore) on 14-16 July 2017, Evidence Based Medicine Forum for Hepato-Biliary-Pancreatic Cancer (Hangzhou) on 4-6 Aug 2017 and ILCA conference (Seoul) on 15-17 Sep 2017 and published in Journal of Clinical Oncology (impact factor: 28.245) on 2 March 2018.
Abstract	The optimal therapeutic regime for locally advanced hepatocellular carcinoma (HCC) with and without vascular invasion remains unclear. This study evaluates the efficacy of Selective Internal Radiation Therapy using SIR-Spheres yttrium-90 microspheres (Y90) versus sorafenib in Asian Barcelona Clinic Liver Cancer (BCLC) stage B and C patients without extra-hepatic metastasis. This investigator-initiated multi-center trial randomized eligible patients with locally advanced inoperable HCC to single injection of Y90 or sorafenib till progressive disease or unacceptable toxicity. The sample size, assuming type I error (two-sided) of 0.05 and power of 90% was 360 patients. Final analysis was planned at 266 reported deaths.
Outcome	The trial found that patients with locally advanced HCC treated with Y90 have statistically significant better tumour-response-rates (TRR) and fewer serious adverse events (SAE) when compared with those treated with sorafenib. There were no statistically significant differences in overall survival between Y90 and sorafenib. SIRT with Y90 is a significantly less toxic therapy with less serious adverse events such as diarrhoea, alopecia, hypertension, fatigue and hand-foot skin reactions. This is also similar to the findings in the SARAH (a similar trial conducted in France). Both trials showed that SIRT with Y90 is a less toxic therapy (for Asians and Europeans) and this is important for patients as SIRT imparts better quality of life. It also provided strong scientific support for the use of SIRT as a less toxic therapy. In the study, SIRT regressed the tumors of a significantly larger numbers of patients than sorafenib. The scientific data from the trial established the safety and efficacy of loco-regional therapy with yttrium-90 in locally advanced HCC and gave clinicians the confidence to use SIRT in a larger number of patients. SIRT-Y90 became standard-of-care for locally advanced HCC patients in NCCS and elsewhere. To date, Singhealth has treated more than 500 HCC patients with Y90. The results were published in Liver Cancer (impact factor: 9.72) in April 2021.

AHCC05	Phase I/II Study of SIR-Spheres plus Sorafenib (Chemo-Radiotherapy) as First Line Treatment in Patients with Non-Resectable Primary Hepatocellular Carcinoma (Clinicaltrials.gov identifier: NCT00712790)
Funding	NMRC and Industry (Sirtex)
Period	1 Jun 2008 to 30 Jun 2011
Status	Completed recruitment of 35 patients in June 2009. Published in PLoS ONE (impact factor: 3.240) on 10 March 2014.
Abstract	The safety and tolerability of sequential radioembolization-sorafenib therapy is unknown. An open-label, single arm, investigator-initiated Phase II study (NCT0071279) was conducted at four Asia-Pacific centers to evaluate the safety and efficacy of sequential radioembolization-sorafenib in patients with hepatocellular carcinoma (HCC) not amenable to curative therapies. Sorafenib was initiated 14 days post-radioembolization with yttrium-90 (90Y) resin microspheres given as a single procedure. The primary endpoints were safety and tolerability and best overall response rate (ORR) using RECIST v1.0. Secondary endpoints included: disease control rate (complete [CR] plus partial responses [PR] and stable disease [SD]) and overall survival (OS).
Outcome	Twenty-nine patients with Barcelona Clinic Liver Cancer (BCLC) stage B (38%) or C (62%) HCC received a median of 3.0 GBq (interquartile range, 1.0) 90Y-microspheres followed by sorafenib (median dose/day, 600.0 mg; median duration, 4.1 months). Twenty-eight patients experienced $1 toxicity; 15 (52%) grade $3. Best ORR was 25%, including 2 (7%) CR and 5 (18%) PR, and 15 (54%) SD. Disease control was 100% and 65% in BCLC stage B and C, respectively. Two patients (7%) had sufficient response to enable radical therapy. Median survivals for BCLC stage B and C were 20.3 and 8.6 months, respectively. This study shows the potential efficacy and manageable toxicity of sequential radioembolization-sorafenib.

AHCC04	Phase II Dose Escalating Trial of Intra-Tumoral BrachySil in Unresectable Hepatocellular Carcinoma (Clinicaltrials.gov identifier: NCT00247260)
Funding	pSiVida Limited and pSiOncology Private Limited
Period	Oct 2005 to Feb 2007
Status	Completed. Results Published in International Journal of Radiation Oncology Biology Physics Vol. 67, Issue 3, 1 March 2007; 786-792.
Abstract	Brachytherapy is a recent technique used in the treatment of tumours and involves the use of radioactive sources brought into close contact with the target tissues. One of the principal benefits of brachytherapy is that high radiation doses can be localised within the tumour with the consequence of minimal side effects. 32P is a radionuclide ideal for brachytherapy as it has high energy beta emitting properties, typically a maximum tissue range of about 8 mm and a half-life of 14.3 days. 32P BioSiliconTM is an active implantable medical device encapsulating 32P within the internal microcrystalline structure of highly pure inert silicon and acts as a sealed source for the provision of 32 phosphorous. Tumours targeted with 32P BioSiliconTM are hypothesized to show a reduction in volume with a low incidence of side effects associated with the treatment. Prolongation of survival and improved quality of life would be favourable outcomes of the investigational product. Patients will be enrolled sequentially into the three groups, starting with Group 1 which will investigate the lower radioactivity level and then progress to a higher radioactivity level in Group 2 and then Group 3. The approval to enroll patients into the next group will be assessed and determined by a Data Monitoring Board. All patients will be followed up to 52 weeks from the start date of primary implantations. Patients will receive intratumoural implantations of 32P BioSiliconTM under imaging guidance and local anaesthesia by designated interventional radiologists, using the SIMPL needle or conventional needles depending on the size and location of the tumour as assessed by the designated interventional radiologists. There are only a designated number of sites that will perform the implantation procedure although there are multiple sites recruiting and following up with patients. Tumour assessment, tumour calculation and measurement will be performed by an independent radiologist. CT scans from all participating sites will be sent in DICOM format to the designated radiologist for assessment. Safety assessment and grading of CTCAE will be performed by the same investigator for that same patient throughout the entire study period. There will be an interim analysis when all patients complete 24 weeks evaluating the safety profile and target tumour response of the patients. 32P BioSiliconTM will be prepared by designated personnel licensed to handle radioactive products and all radioactive waste will be handed and managed as per the institution's guidelines and in compliance with local regulatory requirements.
Outcome	Implantations were successfully carried out in 8 patients (13–74 MBq, mean 40 MBq per tumor) awake and under local anesthesia. Six of the 8 patients reported 19 adverse events, but no serious events were attributable to the study device. Changes in hematology and clinical chemistry were similarly minimal and reflected progressive underlying hepatic disease. All targeted tumors were responding at 12 weeks, with complete response (100% regression) in three lesions. At the end of the study, there were two complete responses, two partial responses, three stable diseases, and one progressive disease. Percutaneous implantation of this novel 32P brachytherapy device into hepatocellular carcinoma is safe and well tolerated. A significant degree of antitumor efficacy was demonstrated at this low dose that warrants further investigation. Publication: Goh, A. S., Chung, A. Y., Lo, R. H., Lau, T. N., Yu, S.

AHCC02	Randomized Double Blind Trial of Megestrol Acetate Versus Placebo for the Treatment of Inoperable Hepatocellular Carcinoma (Clinicaltrials.gov identifier: NCT00041275)
Funding	Pivotal Clinical Trials Grant from SingHealth
Period	Mar 2002 to Jun 2007
Status	Completed recruitment of 204 patients in June 2007. Results published in British Journal of Cancer on 23 August 2011.
Abstract	Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide. We tested megestrol acetate (MA) against placebo in the treatment of advanced HCC. From 2002 through 2007, this randomised double-blind trial enrolled 204 patients with treatment-naive advanced HCC (Eastern Cooperative Oncology Group (ECOG) performance rating of 0-3) from specialist care centres in six Asia-Pacific nations. Patients received placebo or MA (320 mg day1). End points were overall survival (OS) and quality of life.
Outcome	An adverse but not statistically significant difference in OS was found for MA vs placebo: median values 1.88 and 2.14 months, respectively (hazard ratio (HR)¼1.25, 95% CI¼0.92–1.71, P¼0.16). However, OS was similar among patients of good functional status (Child-Pugh A and ECOG 0, 1 or 2) (44.3%) in both treatment groups, with the adverse effect of MA confined to those of poor status. Megestrol acetate patients had a worse global health status (not statistically significant) but reduced levels of appetite loss and nausea/ vomiting. Megestrol acetate has no role in prolonging OS in advanced treatment-naive HCC. Overall survival with placebo differed markedly from that in similar trials conducted elsewhere, suggesting therapeutic outcomes may be strongly dependent on ECOG status and Child-Pugh score.

AHCC01	Randomised Trial of Tamoxifen Versus Placebo for the Treatment of Inoperable Hepatocellular Carcinoma (Clinicaltrials.gov identifier: NCT00003424)
Funding	NMRC
Period	4 Apr 1997 to 8 Jun 2000
Status	Completed recruitment of 324 patients in June 2000. Results published in Hepatology on 20 August 2002.
Abstract	Hepatocellular carcinoma (HCC) is endemic in the Asia-Pacific region. Surgery is the only treatment modality that significantly prolongs survival but almost 90% of patients are inoperable at diagnosis. Tamoxifen (TMX) is believed to retard HCC positive for estrogen receptor (ER), but previous phase III trials in inoperable HCC have been conflicting and inconclusive. Most HCCs are also ER negative. Tamoxifen at higher doses, is however, known to retard HCC through ER-independent mechanisms. The objective of the project was to assess the role of high-dose TMX versus placebo (p) in the treatment of inoperable HCC with survival as the primary endpoint and quality of life (QoL) as the secondary end-point. The methodology used was a prospective double-blind controlled randomized trial with TMX 120mg/day in the study arm and P in the control arm and an intermediate dose arm of TMX 60 mg/day to assess possible dose response. Randomisation was done through the data center in Singapore. Trial safety and quality controlled was ensured via site audits and an independent Data Monitoring Committee. QoL of patients was assessed using the EORTC QLQ-C30 questionnaire.
Outcome	329 patients were recruited. Reported adverse drug reaction was 3% and 8 patients were lost to follow-up. The 3-month survival rates for P, TMX60 and TMX 120 were 44%, 41% and 35% respectively with significant trend difference in crude survival rates across the 3 treatment regimens (p=0.011). There is a significantly higher risk of death in TMX120 as compared with P (HR:1.39;95% CI of HR: 1.07 to 1.81). In conclusion, TMX does not prolong survival in inoperable HCC and has a negative impact with increasing dose. Changed international clinical practice with respect to the treatment of inoperable HCC. The practice of treating such patients with tamoxifen was found to be detrimental. Publication: Chow, P. K., Tai, B. C., Tan, C. K., Machin, D., Win, K. M., Johnson, P. J., and Soo, K. C.
