Tiziana Life Sciences plc (NASDAQ: TLSA / AIM: TILS), a biotechnology company focusing on the discovery and development of innovative therapeutics for inflammation and oncology indications, today announced preliminary topline clinical data from a Phase 2a trial of Milciclib as a monotherapy in patients with advanced hepatocellular carcinoma (HCC), the most common form of liver cancer. The primary endpoint of the study was overall safety. Under compassionate use, a few patients continued with total treatment for up to 16 months. Overall, treatment with Milciclib was well-tolerated and no drug-related deaths were recorded. Secondary endpoints of efficacy including progression-free survival (PFS) and time to progression (TTP) are currently being evaluated and will subsequently be reported.
This Phase 2a trial with Milciclib monotherapy was a multi-centered, single-arm, repeated-dose (100 mg once daily; 4 days on/3 days off every 4 weeks; defining each cycle), 6-month duration study to evaluate the safety, tolerability and anti-tumor activity of Milciclib in sorafenib-refractory or intolerant patients with unresectable or metastatic advanced HCC. This trial enrolled 31 patients in Italy, Greece, and Israel.
Among the 28 evaluable patients, 14 completed the 6-month duration study. Oral treatment with Milciclib was well-tolerated with manageable toxicities. The most frequent adverse events such as diarrhea, ascites, nausea, fatigue, asthenia, fever, ataxia, headache, and rash were manageable.
9 out of the 14 patients, after completing the 6-month trial period, requested to continue the treatment under compassionate use and were approved by their respective ethical committees. Four of the patients received Milciclib for a total of 9, 11, 13 and 16 months. The remaining 5 patients are continuing treatment with Milciclib are at 8th, 9th, 9th, 9th and 11th month currently.
