"A combination approach with an immunotherapy, whose activity may complement existing agents such as INLYTA, has the potential to improve outcomes for patients with advanced renal cancer – a disease where the five-year survival rate remains low," said Chris Boshoff, M.D., Ph.D., Senior Vice President and Head of Immuno-Oncology, Early Development and Translational Oncology, Pfizer Global Product Development. "Pfizer’s expertise in developing treatments for advanced RCC is a distinct advantage in tackling this tumor type, and we look forward to the completion of our Phase III study combining avelumab with INLYTA, which we’re expecting at the end of next year."

"This announcement reinforces the need for innovative first-line treatments for advanced RCC and our promise to advancing care for these patients," said Luciano Rossetti, M.D., Global Head of Research & Development at the Biopharma business of Merck KGaA, Darmstadt, Germany. "The second Breakthrough Therapy Designation by the FDA in another hard-to-treat cancer underlines our focus on challenging tumor types."

RCC is the most common form of kidney cancer, with an estimated 57,500 new cases diagnosed in the US in 2017.1,3 This disease is serious and life-threatening, and approximately 20–30% of patients are first diagnosed at an advanced or metastatic stage.4

The Breakthrough Therapy Designation is based on the preliminary evaluation of clinical data from JAVELIN Renal 100, a global Phase Ib study assessing the safety and efficacy of avelumab in combination with INLYTA for the treatment of treatment-naïve patients with advanced RCC. Updated results from this Phase Ib study were presented at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. The FDA previously granted avelumab Breakthrough Therapy Designation for the treatment of patients with metastatic Merkel cell carcinoma (mMCC) whose disease has progressed after at least one previous chemotherapy regimen.

The clinical development program for avelumab, known as JAVELIN, involves at least 30 clinical programs and over 7,000 patients evaluated across more than 15 different tumor types. This includes JAVELIN Renal 101, a randomized, Phase III, open-label, multicenter trial investigating avelumab in combination with INLYTA versus sunitinib as a first-line treatment option for advanced RCC, which recently completed recruitment. In addition to RCC, cancer studies in the JAVELIN program include non-small cell lung cancer, breast cancer, head and neck cancer, Hodgkin’s lymphoma, melanoma, mesothelioma, MCC, ovarian cancer, gastric/gastroesophageal junction cancer, and urothelial carcinoma (UC).

*Avelumab is under clinical investigation for advanced renal cell carcinoma and has not been demonstrated to be safe and effective for this indication. There is no guarantee that avelumab will be approved for advanced renal cell carcinoma by any health authority worldwide. INLYTA is under clinical investigation for this use in combination with avelumab. In the US, INLYTA is approved as monotherapy for the treatment of advanced RCC after failure of one prior systemic therapy.

About the FDA Designation
Breakthrough Therapy Designation is designed to expedite the development and review of drugs which are intended to treat a serious condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s). The FDA’s granting of the Breakthrough Therapy Designation for metastatic RCC does not alter the standard regulatory requirement to establish the safety and effectiveness of a drug through adequate and well-controlled studies to support approval.

About Renal Cell Carcinoma (RCC)
RCC is the most common form of kidney cancer, accounting for about 2–3% of all cancers in adults.1,5 The most common type of RCC is clear cell carcinoma, accounting for approximately 70% of all cases.3 In 2012, there were approximately 304,000 new cases of RCC diagnosed worldwide, with an estimated 57,500 cases in the US alone in 2017.3,4,6 Incidence varies substantially worldwide with generally higher rates seen in Eastern Asia, North America and Central/Eastern Europe.7 The five-year overall survival rate for patients with distant metastatic RCC is approximately 12%.2

About JAVELIN Renal 100
JAVELIN Renal 100 is a Phase Ib, open-label, multicenter, multiple-dose study investigating avelumab in combination with INLYTA (axitinib), a tyrosine kinase inhibitor from Pfizer, for the treatment of treatment-naïve patients with advanced RCC. The study enrolled 55 patients from participating sites in the US, United Kingdom and Japan.

About Avelumab
Avelumab is a human anti-programmed death ligand-1 (PD-L1) antibody. Avelumab has been shown in preclinical models to engage both the adaptive and innate immune functions. By blocking the interaction of PD-L1 with PD-1 receptors, avelumab has been shown to release the suppression of the T cell-mediated antitumor immune response in preclinical models.7-9 Avelumab has also been shown to induce NK cell-mediated direct tumor cell lysis via antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro.9-11 In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

Approved Indications in the US
The FDA granted accelerated approval for avelumab (BAVENCIO) for the treatment of (i) adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (mMCC) and (ii) patients with locally advanced or metastatic urothelial carcinoma (UC) who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications are approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

Important Safety Information from the US FDA Approved Label
BAVENCIO can cause immune-mediated pneumonitis, including fatal cases. Monitor patients for signs and symptoms of pneumonitis, and evaluate suspected cases with radiographic imaging. Administer corticosteroids for Grade 2 or greater pneumonitis. Withhold BAVENCIO for moderate (Grade 2) and permanently discontinue for severe (Grade 3), life-threatening (Grade 4), or recurrent moderate (Grade 2) pneumonitis. Pneumonitis occurred in 1.2% (21/1738) of patients, including one (0.1%) patient with Grade 5, one (0.1%) with Grade 4, and five (0.3%) with Grade 3.

BAVENCIO can cause immune-mediated hepatitis, including fatal cases. Monitor patients for abnormal liver tests prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater hepatitis. Withhold BAVENCIO for moderate (Grade 2) immune-mediated hepatitis until resolution and permanently discontinue for severe (Grade 3) or life-threatening (Grade 4) immune-mediated hepatitis. Immune-mediated hepatitis was reported in 0.9% (16/1738) of patients, including two (0.1%) patients with Grade 5, and 11 (0.6%) with Grade 3.

BAVENCIO can cause immune-mediated colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 or greater colitis. Withhold BAVENCIO until resolution for moderate or severe (Grade 2 or 3) colitis, and permanently discontinue for life-threatening (Grade 4) or recurrent (Grade 3) colitis upon reinitiation of BAVENCIO. Immune-mediated colitis occurred in 1.5% (26/1738) of patients, including seven (0.4%) with Grade 3.

BAVENCIO can cause immune-mediated endocrinopathies, including adrenal insufficiency, thyroid disorders, and type 1 diabetes mellitus.
Monitor patients for signs and symptoms of adrenal insufficiency during and after treatment, and administer corticosteroids as appropriate. Withhold BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) adrenal insufficiency. Adrenal insufficiency was reported in 0.5% (8/1738) of patients, including one (0.1%) with Grade 3.
Thyroid disorders can occur at any time during treatment. Monitor patients for changes in thyroid function at the start of treatment, periodically during treatment, and as indicated based on clinical evaluation. Manage hypothyroidism with hormone replacement therapy and hyperthyroidism with medical management. Withhold BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) thyroid disorders. Thyroid disorders, including hypothyroidism, hyperthyroidism, and thyroiditis, were reported in 6% (98/1738) of patients, including three (0.2%) with Grade 3.
Type 1 diabetes mellitus including diabetic ketoacidosis: Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Withhold BAVENCIO and administer antihyperglycemics or insulin in patients with severe or life-threatening (Grade ≥ 3) hyperglycemia, and resume treatment when metabolic control is achieved. Type 1 diabetes mellitus without an alternative etiology occurred in 0.1% (2/1738) of patients, including two cases of Grade 3 hyperglycemia.

BAVENCIO can cause immune-mediated nephritis and renal dysfunction. Monitor patients for elevated serum creatinine prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater nephritis. Withhold BAVENCIO for moderate (Grade 2) or severe (Grade 3) nephritis until resolution to Grade 1 or lower. Permanently discontinue BAVENCIO for life-threatening (Grade 4) nephritis. Immune-mediated nephritis occurred in 0.1% (1/1738) of patients.

BAVENCIO can result in other severe and fatal immune-mediated adverse reactions involving any organ system during treatment or after treatment discontinuation. For suspected immune-mediated adverse reactions, evaluate to confirm or rule out an immune-mediated adverse reaction and to exclude other causes. Depending on the severity of the adverse reaction, withhold or permanently discontinue BAVENCIO, administer high-dose corticosteroids, and initiate hormone replacement therapy, if appropriate. Resume BAVENCIO when the immune-mediated adverse reaction remains at Grade 1 or lower following a corticosteroid taper. Permanently discontinue BAVENCIO for any severe (Grade 3) immune-mediated adverse reaction that recurs and for any life-threatening (Grade 4) immune-mediated adverse reaction. The following clinically significant immune-mediated adverse reactions occurred in less than 1% of 1738 patients treated with BAVENCIO: myocarditis with fatal cases, myositis, psoriasis, arthritis, exfoliative dermatitis, erythema multiforme, pemphigoid, hypopituitarism, uveitis, Guillain-Barré syndrome, and systemic inflammatory response.

BAVENCIO can cause severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Patients should be premedicated with an antihistamine and acetaminophen prior to the first 4 infusions and for subsequent doses based upon clinical judgment and presence/severity of prior infusion reactions. Monitor patients for signs and symptoms of infusion-related reactions, including pyrexia, chills, flushing, hypotension, dyspnea, wheezing, back pain, abdominal pain, and urticaria. Interrupt or slow the rate of infusion for mild (Grade 1) or moderate (Grade 2) infusion-related reactions. Permanently discontinue BAVENCIO for severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Infusion-related reactions occurred in 25% (439/1738) of patients, including three (0.2%) patients with Grade 4 and nine (0.5%) with Grade 3.

BAVENCIO can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to a fetus including the risk of fetal death. Advise females of childbearing potential to use effective contraception during treatment with BAVENCIO and for at least 1 month after the last dose of BAVENCIO. It is not known whether BAVENCIO is excreted in human milk. Advise a lactating woman not to breastfeed during treatment and for at least 1 month after the last dose of BAVENCIO due to the potential for serious adverse reactions in breastfed infants.

About INLYTA (axitinib)
INLYTA is an oral therapy that is designed to inhibit tyrosine kinases, including vascular endothelial growth factor (VEGF) receptors 1, 2 and 3; these receptors can influence tumor growth, vascular angiogenesis and progression of cancer (the spread of tumors). In the U.S., INLYTA is approved for the treatment of advanced RCC after failure of one prior systemic therapy. INLYTA is also approved by the European Medicines Agency (EMA) for use in the EU in adult patients with advanced RCC after failure of prior treatment with sunitinib or a cytokine.

INLYTA Important Safety Information
Hypertension including hypertensive crisis has been observed. Blood pressure should be well controlled prior to initiating INLYTA. Monitor for hypertension and treat as needed. For persistent hypertension, despite use of antihypertensive medications, reduce the dose. Discontinue INLYTA if hypertension is severe and persistent despite use of antihypertensive therapy and dose reduction of INLYTA, and discontinuation should be considered if there is evidence of hypertensive crisis.

Arterial and venous thrombotic events have been observed and can be fatal. Use with caution in patients who are at increased risk or who have a history of these events.

Hemorrhagic events, including fatal events, have been reported. INLYTA has not been studied in patients with evidence of untreated brain metastasis or recent active gastrointestinal bleeding and should not be used in those patients. If any bleeding requires medical intervention, temporarily interrupt the INLYTA dose.

Cardiac failure has been observed and can be fatal. Monitor for signs or symptoms of cardiac failure throughout treatment with INLYTA. Management of cardiac failure may require permanent discontinuation of INLYTA.

Gastrointestinal perforation and fistula, including death, have occurred. Use with caution in patients at risk for gastrointestinal perforation or fistula. Monitor for symptoms of gastrointestinal perforation or fistula periodically throughout treatment.

Hypothyroidism requiring thyroid hormone replacement has been reported. Monitor thyroid function before initiation of, and periodically throughout, treatment.

No formal studies of the effect of INLYTA on wound healing have been conducted. Stop INLYTA at least 24 hours prior to scheduled surgery.

Reversible Posterior Leukoencephalopathy Syndrome (RPLS) has been observed. If signs or symptoms occur, permanently discontinue treatment.

Monitor for proteinuria before initiation of, and periodically throughout, treatment. For moderate to severe proteinuria, reduce the dose or temporarily interrupt treatment.

Liver enzyme elevation has been observed during treatment with INLYTA. Monitor ALT, AST, and bilirubin before initiation of, and periodically throughout, treatment.

For patients with moderate hepatic impairment, the starting dose should be decreased. INLYTA has not been studied in patients with severe hepatic impairment.

Women of childbearing potential should be advised of potential hazard to the fetus and to avoid becoming pregnant while receiving INLYTA.

Avoid strong CYP3A4/5 inhibitors. If unavoidable, reduce the dose. Grapefruit or grapefruit juice may also increase INLYTA plasma concentrations and should be avoided.

Avoid strong CYP3A4/5 inducers and, if possible, avoid moderate CYP3A4/5 inducers.

"With a discerning syndicate of investors committed to our science, our strategy and our team, we look forward to using the proceeds of this Series C financing to advance our robust pipeline of small molecule immuno-oncology compounds focused on regulatory T cell and tumor myeloid cell modulation," said Brian Wong, M.D., Ph.D., President and CEO. "In addition to initiating Phase 1 testing for our lead molecule FLX475, a highly potent and selective oral CCR4 antagonist for the treatment of cancer, we intend to select a clinical candidate targeting USP7 and continue advancement of our GCN2 program, with all three programs representing differentiated and important mechanisms to stimulate an immune response within the tumor microenvironment."

Initiation of Phase 1 Clinical Study of FLX475, CCR4 Antagonist
In addition to announcing its financing, FLX Bio recently dosed its first subject in a Phase 1 clinical trial for FLX475, a best-in-class, oral small molecule antagonist of CCR4. The company’s strategy is to accelerate early clinical development in cancer patients by first rapidly obtaining pharmacokinetic, pharmacodynamic, and preliminary safety data in healthy volunteers. Findings from the healthy volunteer study will enable a more focused and efficient Phase 1 study in cancer patients, potentially resulting in faster achievement of clinical proof of concept.

"We are pleased to move our lead program forward into the clinic," commented Bill Ho, M.D., Ph.D., Chief Medical Officer of FLX Bio. "Regulatory T cells are highly potent suppressors of the adaptive immune response and their presence in most tumors are correlated with a poor prognosis. With very few agents in development selectively inhibiting these cells, we believe targeting CCR4 represents a differentiated and exceptionally promising approach to treating cancer."

About FLX475
FLX475 is a best-in-class oral, small molecule antagonist of CCR4. In preclinical studies, FLX475 inhibited tumor growth and increased tumor regression as a single agent. In addition, FLX475 enhanced the antitumor effects of various checkpoint inhibitors including anti-PD-L1 and anti-CTLA4 antibodies as well as immune agonists such as anti-4-1BB. FLX475 also has the potential to enhance cell-based immunotherapies such as CAR-T and cancer vaccines. Unlike antibodies to CCR4, FLX475 selectively blocks the recruitment of regulatory T cells to the tumor site, and does not deplete cells beneficial to an anti-tumor response or regulatory T cells in healthy tissue such as blood, spleen and skin cells. In addition to the study ongoing in healthy volunteers, FLX Bio intends to initiate a clinical trial of FLX475 alone and in combination with a checkpoint inhibitor in oncology patients in 2018.

About USP7
Ubiquitin specific protease 7 (USP7) plays a key role in two important cancer pathways: it promotes the formation and function of regulatory T cells by deubiquitinating and stabilizing FOXP3; and it maintains low levels of p53, a prevalent tumor suppressor protein, thereby allowing the tumor to grow unchecked. USP7 is an enzyme that removes a tag called ubiquitin from proteins and stabilizes the expression of those proteins in the cell. USP7 stabilizes a regulatory protein called FOXP3 found within regulatory T cells, and promotes the number and activity of regulatory T cells. In addition, USP7 stabilizes MDM2, causing p53 levels go down, thus allowing cancer cells to proliferate. A USP7 inhibitor elicits two beneficial effects – increased immune system response to the tumor and enhanced tumor suppression by p53. FLX Bio expects to select a clinical candidate in late 2018.

About GCN2
GCN2 is a myeloid-derived suppressor cell (MDSC) target that works downstream of IDO and arginase. GCN2 inhibition has the potential for superior efficacy as it can reverse immune-suppression caused by depletion of both tryptophan and arginine. We are developing orally-bioavailable, highly-selective GCN2 inhibitors that stimulate an immune response by limiting myeloid derived suppressor cell functions as well as encouraging effector T cell proliferation in the amino acid-deprived tumor microenvironment.
