Update on Phase 1/2 clinical trial of SCIB1 in Stage III/IV melanoma

Scancell Holdings plc (‘Scancell’ or the ‘Company’), the developer of novel immunotherapies for the treatment of cancer, is pleased to announce further encouraging results from its on-going Phase 1/2 clinical trial in patients with Stage III/IV melanoma treated with the SCIB1 ImmunoBody®. The updated data was presented in a poster at the 2014 American Society of Clinical Oncology (ASCO) meeting in Chicago on Sunday 1 June 2014.

The Phase 1/2 trial is an open label, non-randomised study to determine the safety and tolerability of four dose levels of SCIB1 administered intramuscularly using an electroporation device. While the primary objective of the study is to access safety and tolerability, the secondary objectives are to evaluate cellular immune responses and to assess any tumour response.

Highlights

  • SCIB1 is safe and well-tolerated, with no dose-limiting or grade 4/5 toxicities observed
  • Five of 11 patients in Part 1 receiving 2, 4 or 8mg doses have shown evidence of a clinical response
  • Part 1 patients receiving 2mg/4mg doses of SCIB1 had 1-year and 2-year survival rates of 100% and 67%, respectively
  • All five Part 1 patients receiving 8mg doses of SCIB1 remain alive
  • All 14 Part 2 patients with resected tumours are still alive 16-24 months after study entry (median 21 months); only three patients have disease progression
  • 24 of 28 (86%) evaluable patients developed melanoma-specific immune responses
  • Survival times are highly encouraging; only 2 of 25 patients receiving at least three doses of 2-8mg of SCIB1 have died since the study started in 2010
  • Eight patients are currently on long term treatment with SCIB1

Prof Lindy Durrant, Joint CEO of Scancell and Professor of Cancer Immunotherapy at Nottingham University, commented:  “As positive and consistent data continues to emerge from this study, our confidence grows that SCIB1 will play an important role in the management of melanoma.  While recognizing the limitations of this open label trial, the results nonetheless detail a high rate of immune responders and a strong immune response with a drug that is well-tolerated and safe. The observation of objective clinical responses and apparent prolongation of survival further add to the evidence that SCIB1 has the potential to dramatically extend lives without the burden of serious side effects in this setting.”

Prof Poulam Patel, Chief Investigator for the trial and Professor of Clinical Oncology at the University of Nottingham, added: “The whole field of cancer immunotherapy is undergoing a fundamental transformation. Although checkpoint inhibitors are continuing to deliver clinical results, the long-term benefits are seemingly only apparent in around a third of patients.  Taking the brake off T cells with checkpoint inhibitors and pressing the accelerator with active immunotherapies such as SCIB1 may be an effective way of overwhelming the disease and increasing efficacy even further.”  

Part 1 higher dose 8mg study interim results (Stage IV disease only)

  • All five patients with Stage IV disease remain alive with a median survival time of 11 months from study entry (range 8-12 months)
  • One patient in this cohort has shown a pronounced reduction in lung metastases following SCIB1 treatment, meeting the RECIST* criteria for a partial response by Week 9 of treatment and has started continuation treatment. This is the second patient in the study to show an objective clinical response
  • A further patient with breast and lung lesions at study entry remained stable for 6 months and is continuing treatment with SCIB1Four of the five patients produced an immune response to SCIB1
  • Immune responses to the 8mg dose, measured by Elispot, were up to 10-fold higher than those seen in the lower dose 4mg group; high frequencies of melanoma-specific T cells exceeding 2% of total blood lymphocytes were observed

Part 1 lower dose 2mg/4mg study update (Stage III/IV disease)

  • The four patients (of six) who were alive at the time of the December 2012 Part 1 report remain alive
  • One patient had multiple tumour lesions which disappeared or decreased in size except for one lesion which was resected; the patient, who is still alive, has subsequently developed another lesion which was also resected
  • Two further patients have remained disease-free for 18 and 35 months respectively, having required regular treatment and resection of metastases prior to SCIB1 treatment
  • Median survival time in Part 1 patients who received at least three treatments with the 2mg/4mg doses of SCIB1 is now 30 months from study entry and 49 months since diagnosis of metastatic disease
  • Five of six patients receiving 2mg/4mg doses of SCIB1 produced an immune response

Part 2 study update (Stage III/IV patients with resected tumours)

  • All 14 study patients produced an immune response to SCIB1 treatment
  • All patients are still alive after being on the study for between 16 and 24 months
  • Only three patients have any evidence of disease progression after 4, 14 and 18 months on the study
  • Median survival time of all Part 2 patients since initiating treatment is currently 21 months and 26 months since diagnosis of metastatic disease

Overall survival

Based on clinical staging according to the American Joint Committee on Cancer (Balch et al., Journal of Clinical Oncology 2009: 27(36), 6199-206), the 12 patients receiving SCIB1 therapy who had tumour present at study entry fall into the following categories: patients with advanced, visceral stage M1c disease (n=4); patients with disease restricted to M1a (n=1) or M1b (n=6) metastases and one patient with no distant metastases (M0). The other 16 patients all had fully-resected metastatic disease (Stage III or IV prior to surgery).

  • Two M1c patients treated with 0.4mg of SCIB1 had rapidly progressing disease and died after 7 months on study - as expected for patients with visceral metastatic disease. The two other M1c patients received at least 4mg doses of SCIB1; one patient died after 13 months and the other is still alive 11 months after study entry
  • The single M1a patient received 2mg/4mg doses and is still alive 38 months after study entry. One M1b patient treated with 0.4 mg of SCIB1 died 16 months after study entry. Of the other five M1b patients, one received 4 mg doses and four received 8 mg doses: they all remain alive. The current median survival time for the M1b patients is 12 months from study entry (range 8-28 months)
  • Sixteen patients with fully-resected metastatic disease received either 2mg or 4mg doses of SCIB1 and all remain alive with a current median survival of 22 months (range 16-35) from trial entry. The nine Stage III patients have survived for a median of 26 months since their last resection prior to study entry and two patients have experienced a recurrence (22%). The seven Stage IV patients have survived for a median time of 24 months since their last resection prior to study entry, with two patients showing evidence of disease progression 18 and 20 months post-surgery; this compares extremely favourably with a SouthWest Oncology Group prospective study of resection in Stage IV melanoma patients in which the median overall survival (i.e., when 50% of the patients had died) was 21 months and the median recurrence-free survival was 5 months from the time of surgery (Sosman et al., Cancer 2011: 117(20), 4740-46)

Safety

  • SCIB1 therapy was well tolerated in all patient groups with no reports of serious drug-related side effects

In conclusion, while this is a Phase 1/2 clinical study and patient numbers are relatively small, there is consistent evidence emerging from this trial that Scancell’s SCIB1 ImmunoBody® therapy can produce a reduction in tumour load as well as inducing a powerful immune response in late-stage melanoma patients. When taken together with the apparent delay in disease progression and increasingly extended survival data, these results are highly encouraging and clearly warrant the continued development of SCIB1 ImmunoBody® as a potentially powerful new addition for the treatment of this disease.

8mg Higher Dose SCIB1 Study On Track

Scancell Holdings Plc, (AIM:SCLP), the developer of novel immunotherapies for the treatment of cancer, is pleased to announce completion of patient dosing with 8mg of SCIB1 ImmunoBody® (‘SCIB1’) in Part 1 of its on-going Phase 1/2 clinical trial in patients with Stage III/IV melanoma.

Following preliminary evidence from Part 1 of the study showing that a 4mg dose of SCIB1 produced an immune response that might be associated with clinical benefit in patients with malignant melanoma, regulatory approval was obtained for treating a cohort of up to six patients with a higher, 8mg dose of SCIB1.  Five patients with metastatic tumour present have been recruited and dosed, with no reported drug or device-related serious adverse events.  Immunology and clinical responses in this higher dose cohort of patients are currently being analysed and will be reported by the end of Q2 2014. 

Regulatory approval to expand Part 2 of the study to include up to 13 patients receiving the 8mg dose was obtained in October 2013.  With the absence of any serious toxicity in the 8mg Part 1 cohort, enrolment into this cohort has now been closed and new patients will be now be recruited into the expanded 8mg Part 2 cohort.  The first such patient was dosed with SCIB1 earlier this week.

Richard Goodfellow, Joint CEO of Scancell, said:  “Our higher dose 8mg SCIB1 study is progressing well.  In view of the continued safety profile of SCIB1 at the higher dose, we are now recruiting for Part 2 of this cohort, which will assess the immune and clinical response to SCIB1 in a larger number of patients with Stage III/IV melanoma.  We look forward to reporting the results from Part 1 of the study later this year.”

Publication of Moditope® Patent

Scancell Holdings Plc, (AIM: SCLP), the developer of novel immunotherapies for the treatment of cancer, is pleased to announce the publication of the patent application underpinning the Company’s Moditope® platform.  When granted, this patent will protect the platform to at least 2033.

The patent application, describes how the Moditope® immunotherapy platform harnesses CD4+ T cells to eradicate tumours.  Moditope® deploys certain tumour-associated peptide epitopes as immunotherapeutic agents to overcome self-tolerance and eradicate tumour cells, with no requirement for blockade inhibitors.  Planning is underway for the manufacture, preclinical testing and first-in-man clinical development of the Modi-1, the first Moditope® immunotherapeutic.  The PCT patent application which has a priority date of 7 August 2012 was published on 13 February 2014 as WO2014/023957.

Prof. Lindy Durrant Professor of Cancer Immunotherapy at the University of Nottingham and Joint CEO of Scancell, said:  “The publication of the patent application is another important milestone in the development of a range of novel immunotherapeutics from the Moditope® platform.  Recent data suggests that Modi-1 may exhibit potent anti-tumour effects even against established aggressive tumours, dramatically improving survival rates.  We look forward to a busy and exciting year in which we continue to prepare Modi-1 for clinical trials which are on schedule to start in early 2016.”

SCIB1 Granted FDA Orphan Drug Status

Scancell Holdings Plc, (AIM: SCLP), the developer of novel immunotherapies for the treatment of cancer, is pleased to announce that the United States Food and Drug Administration (‘FDA’) has granted orphan drug designation to its SCIB1 ImmunoBody® (‘SCIB1’) for the treatment of metastatic melanoma.

Orphan drug status in the United States qualifies the development of SCIB1 for a 50% tax credit for clinical trials, a waiver of the prescription drug user fee for the drug approval procedure and a period of seven years of market exclusivity following drug approval by the FDA. During the orphan market exclusivity period, the FDA cannot approve a NDA (new drug application) or a generic drug application for the same product including the principal molecular structure features of the drug and for the same rare disease indication.

The Orphan Drug Designation program provides orphan status to drugs and biologics which are defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases/disorders that affect fewer than 200,000 people in the U.S., or that affect more than 200,000 persons but are not expected to recover the costs of developing and marketing a treatment drug.1

Richard Goodfellow, Joint CEO of Scancell, said: “The grant of orphan drug status gives SCIB1 further protection in our key US market in addition to our patent portfolio. We also welcome the financial incentives afforded by such a designation. Following encouraging data from Part 2 of our SCIB1 Phase I/II trial announced in December, development work continues apace and we look forward to disclosing data from additional patients receiving the 8mg dose in due course. ”
