Helix’s L-DOS47 strategic development plan has two parts. The first part is to ensure L-DOS47 will be used in a well-established treatment setting, while being ready to be applied in novel therapies. For this reason, L-DOS47 clinical programs will focus primarily in a combination setting. In this plan L-DOS47 will be studied with well-established chemotherapeutics and in combination with novel immunotherapy. The Company is well advanced in carrying out the study of L-DOS47 with chemotherapy in lung cancer. The planning for combining with immunotherapies in this indication is also in progress.

In the second part of the strategic development plan, the Company will focus on expanding the utility of L-DOS47 to indications other than lung cancer. In choosing a new indication for L-DOS47, the company has considered available preclinical and clinical L-DOS47 data, consulted with key opinion leaders and considered the best strategic application of limited financial resources. To this end, the Company has recently announced the start of a new pancreatic cancer program.

As of today, the Company has completed a monotherapy study of L-DOS47 in lung cancer, with two combination studies in the same indication that are actively recruiting patients. The Company is also working diligently to prepare for regulatory filing of a new pancreatic cancer study with the United Sates Food and Drug Administration ("FDA").

The following is a status update of active studies currently taking place.

LDOS001

LDOS001 is a Phase I dose escalation study of L-DOS47 with pemetrexed and carboplatin for the first line treatment in recurrent or metastatic non-squamous non-small cell lung cancer. A total of seven (7) cohorts comprising of L-DOS47 doses at 0.59, 0.78, 1.5, 3.0, 6.0, 9.0 and 12.0 ug/kg were approved. To date, five (5) cohorts have been completed and a total of 12 patients were dosed. No dose limiting toxicity was observed. In cohort 1, one patient had a partial response (36% tumor regression). In cohort 2, three other patients had partial response (40%, 44% and 91% tumor regression) and one additional patient experienced stable disease for 13.3 months. In cohort 4, one patient had a partial response (69% tumor regression). The company expects to enroll six more patients to complete recruitment for study dosing cohorts if no dose limiting toxicity is observed.

LDOS003

LDOS003 is a phase II, open-Label, randomized study of immunoconjugate L-DOS47 in combination with vinorelbine and cisplatin versus vinorelbine and cisplatin alone in patients with lung adenocarcinoma. Regulatory and Ethics approvals to dose patients were first received from Ukraine in March and from Poland in April. While the company had planned to enroll patient shortly thereafter, the program was delayed due to financial constraints. The company has recently reprioritized its resources and expects to enroll patients in this study immediately.

LDOS006

The Company recently announced the launch of a U.S. Phase I/II study of L-DOS47 in combination with doxorubicin for the treatment of metastatic pancreatic cancer. The study will be led by Dr. Daniel Von Hoff and his team. The Company is currently completing the study protocol and related documents necessary for an investigational new drug ("IND") application to the FDA.

ISA Pharmaceuticals´ Chief Scientific Officer Prof. Cornelis Melief Receives ESMO Immuno-Oncology Award 2018

On November 13, 2018 ISA Pharmaceuticals B.V., a clinical-stage immuno-oncology company, reported that its Chief Scientific Officer Prof. Cornelis Melief has been selected by the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) to receive the 2018 ESMO (Free ESMO Whitepaper) Immuno-Oncology Award in recognition of his life’s work in studying the interactions of the immune system with cancer (Press release, ISA Pharmaceuticals, NOV 13, 2018, View Source [SID1234531236]). He will receive the award during an official ceremony at the opening keynote and award lecture of this year’s ESMO (Free ESMO Whitepaper) Immuno-Oncology Congress in Geneva, Switzerland, on December 13, 2018 (01:30-01:45 pm CET, Hall A2 – Room A).

Prof. Melief will be the second recipient of the ESMO (Free ESMO Whitepaper) Immuno-Oncology Award, which was created in 2017 in commemoration of European cancer research and treatment pioneer Prof. Georges Mathé, a founding member of ESMO (Free ESMO Whitepaper).

In addition to his role at ISA Pharmaceuticals, Prof. Melief is Professor Emeritus in tumor immunology at the Leiden University Medical Center in the Netherlands. He focuses on the development of effective immunotherapies for virus-induced tumors and has created the concept of synthetic long peptide (SLP) vaccines for the treatment of cancer patients. Prof. Melief and his team were able to show the clinical effectiveness of these therapeutic vaccines in patients with pre-malignant lesions caused by Human Papilloma Virus type 16 (HPV-16).

Among the most promising results obtained to date, Melief and his team found that a combination of SLP vaccination and standard chemotherapy strengthened cervical cancer patients’ immune response and prolonged their survival. They further discovered that a similar effect could be achieved among patients with HPV-related head and neck cancer by administering the vaccines in conjunction with immunotherapy in the form of immune system boosting monoclonal antibodies.

Prof. George Coukos and John Haanen, Scientific Co-Chairs of the upcoming congress, outlined the reasons for nominating Cornelis Melief:

"Professor Melief dedicated his career to understanding how the immune system, specifically cytotoxic lymphocytes, interact with cancer, and used this knowledge for the development of new therapeutic cancer vaccine strategies," said Coukos.

"With this award, we are recognizing him as a true pioneer in the field of cancer immunology, who has trained and inspired a whole generation of young scientists with his research," Haanen added.

"This is a great honor and a wonderful recognition of the fact that after many years of concept building and evaluation in lab models and investigational trials, we have finally arrived at immunotherapy approaches that can make a difference for patients," said Prof. Cornelis Melief. "To me, this award also means recognition of the outstanding teamwork delivered by talented investigators at Leiden University Medical Center and ISA Pharmaceuticals as well as by many medical oncologists in the Netherlands, Belgium and the USA."

Sutro Announces IND Submission and Conclusion of 30-Day Review Period for STRO-002, an Antibody-Drug Conjugate (ADC) Targeting Anti-Folate Receptor-α for Treatment of Ovarian and Endometrial Cancer

On November 13, 2018 Sutro Biopharma, Inc. (NASDAQ: STRO), reported that the U.S. Food and Drug Administration (FDA) has concluded their 30-day review of the Investigational New Drug (IND) application for STRO-002 to be evaluated in a Phase1 clinical study as a potential treatment for ovarian and endometrial cancer (Press release, Sutro Biopharma, NOV 13, 2018, View Source [SID1234531416]). The antibody-drug conjugate STRO-002 targets folate receptor-α, a cell-surface protein expressed in 80% of ovarian and endometrial cancers.

"The ability to begin our Phase I clinical study marks an important milestone that expands Sutro’s clinical development pipeline and further validates our technology for the design of unique and potent antibody-drug conjugates," said Bill Newell, Sutro’s Chief Executive Officer. "The Phase 1 clinical trial of STRO-002 is expected to begin in early 2019 with the goal to investigate the safety, tolerability and preliminary anti-tumor activity of STRO-002 in patients with gynecologic malignancies."

Patients with ovarian cancer will be enrolled during the dose escalation-phase of the study, and two separate cohorts for ovarian and endometrial cancer will be evaluated during dose expansion.

"Ovarian and endometrial cancer patients need targeted treatment options with better tolerability and efficacy," commented Dr. Wendel Naumann, MD Gynecologic Oncologist Professor, Dept. Ob/Gyn Levine Cancer Institute, Carolinas Medical Center.

In preclinical studies, STRO-002 effectively delivered its cytotoxin to targeted cancer cells without significant accumulation of a toxic metabolite in the blood. Testing of clinically relevant doses in non-human primates showed no evidence of ocular toxicity, a vexing problem associated with conventional ADCs containing standard tubulin-inhibiting agents.

"This is an important development for ADC-based cancer therapeutics and could provide new means to achieving greater anti-tumor activity in the clinic before the onset of dose-limiting side effects," added Dr. Arturo Molina, Sutro’s Chief Medical Officer.

Unlike first-generation ADCs, STRO-002 is a homogeneous, site-specific antibody-drug conjugate that incorporates a novel, proprietary linker-warhead, thereby enabling effective and precise payload delivery to targeted cancer cells. Preclinical studies demonstrated STRO-002’s potent in vitro cytotoxicity in ovarian and endometrial cancer cell lines, and tumor growth inhibition in multiple in vivo ovarian and endometrial cancer models. Safety studies conducted in non-human primates have shown tolerability at clinically relevant doses with no observed ocular toxicity.

About STRO-002

STRO-002 was developed with Sutro’s proprietary cell-free protein synthesis and site-specific conjugation platform, XpressCF+TM, which enables precise design, rapid empirical optimization, and manufacture of site-specific ADCs. Sutro’s technology results in highly optimized ADCs comprising a single molecular species, in contrast to first-generation commercial ADCs that comprise a mixture of imprecisely conjugated antibodies. STRO-002 has been engineered to use Sutro’s novel, proprietary SC239 linker-warhead, designed for increased stability and potency, which results ineffective targeting of cancer cells and precise delivery of the payload.

FDA Grants Priority Review to Genentech’s Tecentriq in Combination with Abraxane for the Initial Treatment of People with PD-L1-Positive, Metastatic Triple-Negative Breast Cancer

On November 13, 2018 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) and granted Priority Review for Tecentriq (atezolizumab) plus chemotherapy (Abraxane [albumin-bound paclitaxel; nab-paclitaxel]) for the initial (first-line) treatment of unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) in people whose disease expresses the PD-L1 protein, as determined by PD-L1 biomarker testing (Press release, Genentech, NOV 13, 2018, View Source [SID1234531212]). The FDA is expected to make a decision on approval by March 12, 2019. A Priority Review designation is granted to medicines that the FDA has determined to have the potential to provide significant improvements in the treatment, prevention or diagnosis of a disease.

"Tecentriq in combination with nab-paclitaxel has the potential to meaningfully advance treatment for people with PD-L1-positive, metastatic triple-negative breast cancer. People need more options for this type of breast cancer, which is particularly difficult to treat," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. "We are working closely with the FDA to bring this Tecentriq combination to people with PD-L1-positive, metastatic triple-negative breast cancer as soon as possible."

The sBLA is based on data from the Phase III IMpassion130 study, which was presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress and published in the New England Journal of Medicine in October 2018. Results demonstrate Tecentriq plus nab-paclitaxel as an initial (first-line) treatment for unresectable locally advanced or metastatic TNBC significantly reduced the risk of disease worsening or death (progression-free survival; PFS) compared with nab-paclitaxel alone in all randomized patients (intention-to-treat [ITT]) (median PFS=7.2 vs. 5.5 months; hazard ratio [HR]=0.80, 95% CI: 0.69-0.92, p=0.0025) and the PD-L1-positive population (median PFS=7.5 vs. 5.0 months; HR=0.62, 95% CI: 0.49-0.78, p<0.0001), a subgroup determined by PD-L1 biomarker testing. At this interim analysis, statistical significance was not met for overall survival (OS) in the ITT population (median OS=21.3 vs. 17.6 months; HR=0.84, 95% CI: 0.69-1.02, p=0.0840), but the combination showed a clinically meaningful OS improvement in the PD-L1-positive population (median OS=25.0 vs. 15.5 months; HR=0.62, 95% CI: 0.45-0.86). Due to the hierarchical statistical design, results in the PD-L1-positive population were not formally tested for statistical significance. Follow-up will continue until the next planned analysis. Safety in the Tecentriq plus nab-paclitaxel arm appeared consistent with the known safety profiles of the individual medicines, and no new safety signals were identified with the combination. Serious adverse events were reported in 23 percent of people who received Tecentriq plus nab-paclitaxel compared to 18 percent of people who received nab-paclitaxel alone.

Currently, Genentech has seven ongoing Phase III studies investigating Tecentriq in TNBC, including early and advanced stages of the disease. If approved, this Tecentriq combination would be the first cancer immunotherapy regimen for the treatment of PD-L1-positive, metastatic TNBC.

About the IMpassion130 study

The IMpassion130 study is a Phase III, multicenter, randomized, double-blind study evaluating the efficacy, safety and pharmacokinetics of Tecentriq plus nab-paclitaxel compared with placebo plus nab-paclitaxel in people with unresectable locally advanced or metastatic TNBC who have not received prior systemic therapy for metastatic breast cancer. The study enrolled 902 people who were randomized equally (1:1). The co-primary endpoints are PFS per investigator assessment (RECIST 1.1) and OS. PFS and OS were assessed in all randomized patients (ITT) and in the PD-L1-positive population. Secondary endpoints include objective response rate, duration of response and time to deterioration in Global Health Status/Health-Related Quality of Life.

About triple-negative breast cancer

Breast cancer is the most common cancer among women worldwide. According to the American Cancer Society, approximately 269,000 people in the United States will be diagnosed with breast cancer, and more than 41,000 will die from the disease in 2018. Breast cancer is not one, but many diseases based on the biology of each tumor. In triple-negative breast cancer, tumor cells lack hormone receptors and do not have excess HER2 protein. Approximately 15 percent of breast cancers are triple-negative based on the results of diagnostic tests. It is an aggressive form of the disease with few treatment options.

About Tecentriq

Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

Abraxane is a registered trademark of Abraxis Bioscience, LLC, a wholly owned subsidiary of Celgene Corporation.

Tecentriq U.S. Indication (pronounced ‘tē-SEN-trik’)

Tecentriq is a prescription medicine used to treat:

A type of bladder and urinary tract cancer called urothelial carcinoma.

Tecentriq may be used when your bladder cancer:
has spread or cannot be removed by surgery, and if you have any one of the following conditions:
you are not able to take chemotherapy that contains a medicine called cisplatin, and your doctor has tested your cancer and found high levels of a specific protein on your cancer called programmed death-ligand 1 (PD-L1), as determined by an FDA-approved test, or
you are not able to take chemotherapy that contains any platinum regardless of PD-L1 status on your cancer, or
you have tried chemotherapy that contains platinum, and it did not work or is no longer working
The approval of Tecentriq in these patients is based on a study that measured response rate and duration of response. There is an ongoing study to confirm clinical benefit.

A type of lung cancer called non-small cell lung cancer (NSCLC).

Tecentriq may be used when your lung cancer:
has spread or grown, and
you have tried chemotherapy that contains platinum, and it did not work or is no longer working
If your tumor has an abnormal EGFR or ALK gene, you should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working.

It is not known if Tecentriq is safe and effective in children.

Important Safety Information

What is the most important information about Tecentriq?

Tecentriq can cause the immune system to attack normal organs and tissues and can affect the way they work. These problems can sometimes become serious or life threatening and can lead to death.
