"Metastatic triple negative breast cancer represents an extreme unmet medical need, where pre-treated patients rarely achieve objective responses with PD-1/PD-L1 checkpoint treatments," said Dr. Pamela Munster, Professor of Medicine and Program Leader of Experimental Therapeutics at University of California San Francisco (UCSF). "The marked synergy of TAVO and checkpoint inhibition shown in previous clinical observations strongly suggests that IL-12 may prime the tumor microenvironment for PD-1/PD-L1 checkpoint treatments. This represents a highly promising therapeutic approach for TNBC."

KEYNOTE-890 is a multicenter Phase 2 open-label trial of TAVO in combination with KEYTRUDA in patients with histologically confirmed diagnosis of inoperable locally advanced or metastatic TNBC and at least one prior line of approved systemic chemotherapy or immunotherapy.

Breast cancer cells that test negative for estrogen receptors (ER-), progesterone receptors (PR-), and HER2 (HER2-) means the cancer is triple negative.1 Approximately 10-20 percent of US breast cancer cases are triple negative breast cancer (TNBC),1 which disproportionately affects younger women as well as African-American women,2 followed by Hispanic women.3

"The initiation of KEYNOTE-890 is an important milestone for OncoSec as it marks a significant expansion of our clinical pipeline as well as our expanding relationship with Merck," said Daniel J. O’Connor, President and Chief Executive Officer of OncoSec. "Our goal is to enroll this study as quickly as possible and provide preliminary topline data in 2019. Currently, overall survival for metastatic TNBC is one to two years from diagnosis, with therapies resulting in short-lived responses and/or significant toxicity. New approaches are desperately needed, and based on prior and ongoing clinical research, we beleive that TAVO in combination with KEYTRUDA has the potential to be effective in treating this disease. Given the severe unmet medical need, it is possible that TAVO for the treatment of TNBC could be granted Fast Track designation, Breakthrough Therapy designation, and be a candidate for accelerated approval."

TNBC remains a poor-prognosis breast cancer subtype,2 with limited treatment options for patients with advanced, recurrent disease. In the recurrent disease setting, chemotherapy remains the standard of care, and median survival is approximately 13 months from the time of disease recurrence.4 Emerging evidence shows immunotherapy options may play an important role in the treatment paradigm for TNBC.5-8 Preliminary data from early-phase studies demonstrated the anti-PD-1 antibody pembrolizumab led to an objective response in 18 to 19 percent of TNBC patients;5-7 and median overall survival was 8.9 months in a pretreated cohort.6 The anti-PD-L1 antibody atezolizumab (MPDL3280A) achieved an objective response in 25 percent of patients in the first-line and 11 percent of patients in the second-line setting.8 There is increasing evidence that tumors need TILs for anti-PD-1/PD-L1 therapies to be most effective.9-12 Data also show TILs promote better responses to chemotherapy and improve clinical outcomes in breast cancer, including TNBC.13-17

On October 15, 2018 Loxo Oncology, Inc. (Nasdaq:LOXO), a biopharmaceutical company developing highly selective medicines for patients with genomically defined cancers, reported that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to LOXO-292, a selective RET inhibitor, for the treatment of patients with advanced RET fusion-positive thyroid cancer who require systemic therapy, have progressed following prior treatment and have no acceptable alternative treatment options (Press release, Loxo Oncology, OCT 15, 2018, View Source [SID1234529908]). This designation supplements the two LOXO-292 Breakthrough Therapy Designations granted in September 2018. The Breakthrough Therapy Designation announced today was also based on data from the ongoing global Phase 1/2 LIBRETTO-001 clinical trial.

The FDA’s Breakthrough Therapy Designation is intended to expedite the development and review of a drug candidate that is planned for use to treat a serious or life-threatening disease or condition when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints.

About LOXO-292
LOXO-292 is an oral and selective investigational new drug in clinical development for the treatment of patients with cancers that harbor abnormalities in the rearranged during transfection (RET) kinase. RET fusions and mutations occur across multiple tumor types with varying frequency. LOXO-292 was designed to inhibit native RET signaling as well as anticipated acquired resistance mechanisms that could otherwise limit the activity of this therapeutic approach. LOXO-292 has been granted Breakthrough Therapy Designation by the U.S. FDA.

LOXO-292 is currently being studied in the global LIBRETTO-001 Phase 1/2 trial. For additional information about the LOXO-292 clinical trial, please refer to www.clinicaltrials.gov. Interested patients and physicians can contact the Loxo Oncology Physician and Patient RET Clinical Trial Hotline at 1-855-RET-4-292 or email [email protected].

About RET-Altered Cancers
Genomic alterations in RET kinase, which include fusions and activating point mutations, lead to overactive RET signaling and uncontrolled cell growth. RET fusions have been identified in approximately 2% of non-small cell lung cancer, 10-20% of papillary and other thyroid cancers, and a subset of other cancers. Activating RET point mutations account for approximately 60% of medullary thyroid cancer (MTC). Both RET fusion cancers and RET-mutant MTC are primarily dependent on this single activated kinase for their proliferation and survival. This dependency, often referred to as "oncogene addiction," renders such tumors highly susceptible to small molecule inhibitors targeting RET.

On October 15, 2018 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported the phase III KATHERINE study met its primary endpoint, showing Kadcyla (trastuzumab emtansine) as a single agent significantly reduced the risk of disease recurrence or death (invasive disease-free survival, iDFS) compared to Herceptin (trastuzumab) as an adjuvant (after surgery) treatment in people with HER2-positive early breast cancer (eBC) who have residual disease (pathological invasive residual disease in the breast and/or axillary nodes) present following neoadjuvant (before surgery) treatment (Press release, Hoffmann-La Roche, OCT 15, 2018, View Source [SID1234529895]). The safety profile of Kadcyla in the KATHERINE study was consistent with previous clinical trials and no new safety signals were identified. [1,2]

"We are highly encouraged by these positive results with adjuvant Kadcyla treatment in people with HER2-positive early breast cancer who have residual disease after neoadjuvant therapy," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We look forward to discussions with regulatory authorities with the goal of bringing this new treatment option to patients as soon as possible."

Full results will be submitted to health authorities around the world, and will be presented at the 2018 San Antonio Breast Cancer Symposium on Wednesday 5 December at 11.00 am CST.

The KATHERINE trial investigated a population of people with HER2-positive eBC who did not achieve a pathological complete response to neoadjuvant treatment. This state of residual disease is associated with a worse prognosis.[3,4]

The goal in treating early breast cancer is to provide people with the best chance for a cure. [5] While we come closer to this goal with each advance, many people still have a disease recurrence in the long-term. [6] Neoadjuvant treatment is given before surgery with the goal of shrinking tumours and helping to improve surgical outcomes. [7,8,9] Adjuvant treatment is given after surgery as part of a complete eBC treatment regimen and is aimed at eliminating any remaining cancer cells in the body, to help reduce the risk of the cancer returning. [7]

About the KATHERINE study[10]
KATHERINE is an international, multi-centre, two-arm, randomised, open-label, phase III study evaluating the efficacy and safety of Kadcyla versus Herceptin as an adjuvant therapy in people with HER2-positive eBC who have pathological residual disease in the breast and/or axillary lymph nodes following neoadjuvant therapy that included Herceptin and taxane-based chemotherapy. The primary endpoint of the study is iDFS, which, in this study, is defined as the time from randomisation to invasive breast cancer recurrence or death from any cause. Secondary endpoints include disease-free survival and overall survival.

About Kadcyla
Kadcyla is an antibody-drug conjugate (ADC) engineered to deliver potent chemotherapy directly to HER2-positive cancer cells, potentially limiting damage to healthy tissues. [1,2] It combines two anti-cancer properties joined together by a stable linker: the HER2-targeting properties of trastuzumab (the active ingredient in Herceptin) and the chemotherapy agent DM1. [11] Kadcyla is the only ADC approved as a single agent in 104 countries including the US and EU for the treatment of people with HER2-positive metastatic breast cancer who have previously received Herceptin and taxane chemotherapy, separately or in combination. Roche licenses technology for Kadcyla under an agreement with ImmunoGen, Inc.

About Roche’s medicines for HER2-positive breast cancer
Roche has been leading research into the HER2 pathway for over 30 years and is committed to improving the health, quality of life and survival of people with both early and advanced HER2-positive disease. HER2-positive breast cancer is a particularly aggressive form of the disease that affects approximately 15-20% of patients. [12] Roche has developed three innovative medicines that have helped transform the treatment of HER2-positive breast cancer: Herceptin (trastuzumab), Perjeta (pertuzumab) and Kadcyla (trastuzumab emtansine). Eligibility for treatment with Roche’s HER2-targeted medicines is determined via a diagnostic test, which identifies people who will likely benefit from these medicines at the onset of their disease.
