Under the agreement, Sprint Bioscience licenses a PIP4k2a inhibitor program targeting tumor metabolism to the Company. Subsequently, the Company will have full control over further development and worldwide commercialization rights for potential cancer therapeutics and diagnostics.

"We are really happy to have closed a deal with a company with world leading expertise in tumor metabolism biology. It will increase the chances to develop a drug to the benefit for cancer patients.."
Dr Anders Åberg, CEO of Sprint Bioscience

As a result of a tumor’s uncontrolled growth, cancer cells exhibit an altered metabolism (tumor metabolism) and thereby are often resistant to conventional radiation- and chemotherapy. Sprint Bioscience has developed molecules inhibiting PIP4K2a, an enzyme involved in regulation of cellular metabolism. Such inhibitors can potentially be developed into new effective anti-cancer treatments by selectively affecting the growth and survival of cancer cells.

Sprint Bioscience is eligible to receive up to approximately 240 Million USD in potential preclinical, clinical and net sales based milestone payments, including a 3 Million USD upfront payment from Company upon signing of the agreement. Furthermore, Sprint Bioscience will in addition receive one-year research funding corresponding to four FTEs with the option of a two times six months’ extension. Sprint Bioscience is also eligible to receive royalties on worldwide net sales of any resulting products under the collaboration.

Titled "Intralesional PV-10 for In-Transit Melanoma – A Single Centre Experience," the article reports on use of PV-10 in the management of in-transit melanoma at the Peter MacCallum Cancer Centre, in East Melbourne, Victoria, Australia. The article was authored by Jocelyn Lippey et al. using retrospective analysis of data from nineteen patients receiving PV-10 at the center between 2010 and 2014.

Dr. Lippey reported, "After a median follow up of 11.7 months, disease control was achieved in 63% of patients. Five patients (26%) achieved a complete response, another five (26%) patients achieved a partial response, and two patients had stable disease (11%) at the time of last follow-up. Seventy-four percent (14/19) of patients had a clinical response at time of first follow-up (median time 21 days); range 8–91 days. Younger patients and those with smaller lesions were more likely to respond to treatment." The median age of patients in this series was 80 years.

Dr. Lippey also noted, "Ten patients did not have all lesions injected, primarily due to the number of lesions present. A bystander response was noted in un-injected lesions in 50% of patients who did not have all their lesions directly injected."

Eric Wachter, CTO of Provectus commented, "The results reported here are consistent with other evaluations of PV-10 in melanoma, and highlight both the rapid ablative properties and the immunologic features of PV-10 as an investigational ablative immunotherapy."

On June 6, 2016 Foundation Medicine, Inc. (NASDAQ:FMI) reported new data informed by comprehensive genomic profiling (CGP) using FoundationOne Heme demonstrating the diverse and distinct genomic landscape of acute myeloid leukemia (AML) in children versus adults (Press release, Foundation Medicine, JUN 6, 2016, View Source [SID:1234513044]). Foundation Medicine conducted comprehensive genomic profiling of tumor samples from 558 patients with AML, including 104 pediatric and 454 adult patients, and identified age-associated genomic alterations in a subset of patients that could influence and personalize treatment and inform the selection of approved targeted therapies or access to novel therapies available in clinical trials.

In collaboration with the Children’s Oncology Group AML Disease Committee, a clinical trials group supported by the National Cancer Institute (NCI), cases with known cytogenetic and molecular aberrations underwent CGP with FoundationOne Heme. The results demonstrated 100% concordance between FoundationOne Heme and conventional biomarker analysis across the various cytogenetic hallmarks of AML, including changes to inv(16) and t(8;21), as well as DNA mutations including FLT3/ITD, NPM1, and CEBPA. Importantly, FoundationOne Heme identified multiple additional mutations, such as structural alterations and copy number variations, including alterations that have therapeutic significance. These results suggest the potential clinical benefit of FoundationOne Heme in AML as compared to single gene or hotspot-based clinical testing, and underscore FoundationOne Heme’s unique capability to enhance risk stratification and identify molecular targets for therapeutic intervention.

The data showed a clear age-associated profile with distinct genomic make-up in pediatric versus adult patients. Novel transcripts such as NSD1-NUP98, KDM5A-NUP98 and CBFA2T3-GLIS2 were identified in 21 patients, 16 of whom were children. Fusions were markedly enriched in pediatric patients, while mutations in epigenetic modifiers occurred almost exclusively in adults, including DNMT3A (22 percent), IDH1/2 (21 percent) and TET2 (15 percent). Mutations in ASXL1 (21 percent), SRSF2 (14 percent) and BCOR (9 percent) were also prevalent in adults, but rare in children (0-6%).

"Like many blood cancers, AML is characterized by recurring genomic alterations that often provide information about disease progression and outcome, making comprehensive genomic profiling incredibly important to informing diagnosis and therapeutic decisions," said Vincent Miller, M.D., chief medical officer, Foundation Medicine. "Recognizing that there are fundamental differences between the genomic alterations in pediatric versus adult AML patients will ultimately arm clinicians with additional information to better understand each patient’s disease and guide therapeutic regimens best suited to a particular age group. We believe these data further support integration of FoundationOne Heme into oncology clinical practice."

The findings were presented in a poster titled, "Distinct Age-Associated Genomic Profiles Identified in Acute Myeloid Leukemia (AML) Using FoundationOne Heme," by Katherine Tarlock, M.D., pediatric hematology-oncology faculty at Seattle Children’s Hospital, and a member of the Children’s Oncology Group AML Committee. The data were presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting 2016 taking place June 3-7 in Chicago.

FoundationOne Heme, an integrated DNA/RNA platform using targeted hybrid-capture next-generation sequencing, is a comprehensive genomic profile developed to detect all types of genomic alterations with therapeutic relevance, including single-nucleotide substitutions, insertions and deletions, copy number alterations and rearrangements, which are not fully evaluated using conventional diagnostic assays. FoundationOne Heme simultaneously detects all classes of genomic alterations in the DNA of 405 cancer-related genes and employs RNA sequencing across 265 genes to capture a broad range of gene fusions, a type of alteration that is a common driver of hematologic cancers. It is designed to provide physicians with clinically actionable information to guide treatment options for patients based on the genomic profile of their cancer.

On June 6, 2016 Five Prime Therapeutics, Inc. (Nasdaq:FPRX), a clinical-stage biotechnology company focused on discovering and developing innovative immuno-oncology protein therapeutics, reported that updated data from the ongoing Phase 1 trial of FPA144 was featured today in an oral presentation during the 2016 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago (Press release, Five Prime Therapeutics, JUN 6, 2016, View Source [SID:1234513068]). Dr. Jeeyun Lee from the Division of Hematology-Oncology, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea, gave the presentation, titled Antitumor Activity and Safety of FPA144, an ADCC-enhanced, FGFR2b Isoform-Selective Monoclonal Antibody, in Patients with FGFR2b+ Gastric Cancer and Advanced Solid Tumors (Abstract 2502). The presentation is available on the Five Prime website: View Source

Part 1 of the trial evaluated escalating doses of FPA144 as a single agent in 27 patients, 19 with advanced solid tumors in Part 1a and 8 with advanced gastric cancer in Part 1b, including 6 with FGFR2b-overexpressing tumors. Enrollment is underway in Part 2 of the trial, evaluating the safety, pharmacokinetics (PK) and efficacy (objective response rate and duration of response) of biweekly 15 mg/kg infusions of FPA144 across multiple cohorts: gastric cancer patients whose tumors have high, moderate and low levels of FGFR2b protein overexpression and gastric cancer patients whose tumors do not have FGFR2b protein overexpression. Five Prime plans to expand the scope of this trial further by the end of 2016 to include a cohort of patients with a tumor type (other than gastric) that overexpresses FGFR2b.

Safety findings presented in this update are consistent with initial data presented during the ASCO (Free ASCO Whitepaper) Gastrointestinal Symposium in January 2016. Data across 40 patients in the full safety population of this trial (all gastric and solid tumor patients receiving any portion of at least one dose of FPA144) suggest that FPA144 has an acceptable safety profile in doses up to 15 mg/kg:

No dose-limiting toxicities (DLTs); maximum-tolerated dose (MTD) was not reached
No treatment-related serious adverse events (SAEs); 17 reported SAEs across 9 patients
No treatment-related adverse events (AEs) resulting in treatment discontinuation
No treatment-related hyperphosphatemia or retinal toxicity (differentiated from small molecule kinase inhibitors targeting FGF receptor tyrosine kinases)
The most common treatment-related AEs ( > 5%) were all grades 1 or 2: fatigue (22.5%), nausea (20%) and vomiting (12.5%)
One transient treatment-related Grade 3 AE of decreased neutrophil count
Comparable safety between gastric cancer patients and full safety population

FPA144 monotherapy demonstrated early evidence of anti-tumor efficacy in the 9 gastric cancer patients with FGFR2b protein overexpression (6 from Part 1b of the trial; 3 from Part 2) that were available for analysis as of the April 1, 2016 data cutoff. These patients were heavily pre-treated, having received between 1 and 6 prior therapies with a median of 2 prior therapies. The activity observed includes:

3 confirmed partial responses (PRs) out of 9 gastric cancer patients treated (33%) (one of these three PRs confirmed after the April 1, 2016 data cutoff)
7 of 9 gastric cancer patients with disease control (3 PRs + 4 stable disease), disease control rate (DCR) = 77%
12-week progression-free survival (PFS) in 6 of 9 gastric cancer patients (67%)
Median duration of treatment of 112 days (range 42-182 days), with 2 of 9 gastric cancer patients still on study
1 complete response (CR) in a patient with metastatic bladder cancer
In addition to the 3 PRs noted above, there was an additional unconfirmed PR in the 10th gastric cancer patient with FGFR2b protein overexpression (the 4th patient in the 15 mg/kg cohort). This 10th patient’s scan became available after the data cutoff of April 1, 2016, and the patient remains on treatment.

"The data suggest that FPA144 is an active drug that warrants further clinical development. The initial single-agent efficacy and safety data seen during the dose escalation portion of the study is encouraging," said Dr. Charles Fuchs, Director of the Center for Gastrointestinal Cancer, Dana Farber Cancer Institute. "Patients with advanced gastric cancer have a significant unmet medical need, and the literature suggests that those with tumors that overexpress FGFR2b have an even worse prognosis. New treatments options are needed for these patients."

"We are pleased with the data from this ongoing trial," said Lewis T. "Rusty" Williams, M.D., Ph.D., president and chief executive officer of Five Prime. "The data we have observed in this trial suggest that FPA144 has an acceptable safety profile and can be dosed biweekly. FPA144 monotherapy also showed evidence of clinical activity in the first nine FGFR2b+ gastric cancer patients that were available for analysis, with a disease control rate of 77% and a 12-week progression free survival of 67%. We were also pleased to see an unexpected complete response in a patient with bladder cancer in part 1a of the trial. We look forward to continuing the study and to further exploring FPA144 in gastric cancer with varying levels of FGFR2b protein overexpression as well as additional FGFR2b+ tumors."

About the FPA144 Phase 1 Trial
Parts 1a and 1b of the Phase 1 study evaluated the safety and pharmacokinetics (PK) of escalating doses of FPA144 in 27 patients with solid tumors, including gastric cancer patients. Enrollment is underway in Part 2 of the trial, evaluating the safety, PK and efficacy (response rate and duration of response) of biweekly 15 mg/kg infusions of FPA144 across multiple cohorts: gastric cancer patients with high, moderate and low levels of FGFR2b protein overexpression, FGFR2b- gastric cancer patients, and FGFR2b+ patients with other tumor types. Up to 30 patients may be enrolled in each tumor setting. Tumors will be biopsied pre- and post-treatment in order to determine levels of FGFR2b protein overexpression and FGFR2 gene amplification, and to detect PD-L1 and immune infiltrate changes within the tumor. Testing for FGFR2b protein overexpression is being conducted centrally, using a proprietary immunohistochemistry assay.

About FPA144
FPA144 is an anti-FGF receptor 2b (FGFR2b) humanized monoclonal antibody in clinical development as a targeted immune therapy for tumors that over-express FGFR2b, as determined by a proprietary immunohistochemistry (IHC) diagnostic assay. FGFR2 gene amplification (as identified by FISH) is found in a number of tumors, including in approximately 5% of gastric cancer patients, and is associated with poor prognosis.

FPA144 is designed to block tumor growth through two distinct mechanisms. First, it has been engineered to drive immune-based killing of tumor cells by antibody-dependent cell-mediated cytotoxicity (ADCC) and the recruitment of natural killer (NK) cells and T cells. Second, it binds specifically to FGFR2b and prevents the binding of certain fibroblast growth factors that promote tumor growth. When combined with PD-1 blockade, FPA144 has shown an additive effect in tumor growth inhibition in preclinical models. Five Prime retains global development and commercialization rights to FPA144.
