Sysmex Obtains First Manufacturing and Marketing Approval in Japan for Blood-Based RAS Gene Mutation Testing for Colorectal Cancer

On August 2, 2019 Sysmex Corporation (HQ: Kobe, Japan; Chairman and CEO: Hisashi Ietsugu) reported that it has obtained Japanese manufacturing and marketing approval for the OncoBEAM1 RAS CRC Kit, used for blood-based circulating tumor DNA molecular testing of mutations in the RAS gene2 for colorectal cancer patients (Press release, Sysmex, AUG 2, 2019, View Source [SID1234538074]). This product is the first in vitro diagnostic reagent in Japan to be used for RAS gene mutation testing for colorectal cancer using liquid biopsy. Minimally invasive and simpler than conventional physical biopsies of tumor tissue, the new testing method provides detection results on a par with the use of tumor tissue.3 As a result, this testing method reduces the physical and mental burden on patients, expands testing opportunities, and contributes to the early-stage determination of treatment methods.

In recent years, demand has grown for the use of liquid biopsy in the diagnosis and selection of treatment methods for cancer and other diseases. Liquid biopsy refers to using blood or other bodily fluids, which place little burden on the patient, rather than physical biopsies, which require taking samples of a cancer tumor or other tissue.4 Sysmex has defined the "resolution of medical issues through products and services" as one of the priority issues (materiality) for realizing a sustainable society and sustainable growth in corporate value for Sysmex through the creation of new technologies and markets. As one aspect of these activities, Sysmex is pursuing R&D toward the realization of personalized medicine, which involves the provision of healthcare optimized for individual patients, and the proliferation of testing to reduce the physical burden on patients.

The OncoBEAM RAS CRC Kit is used to test samples of tumor-derived DNA (circulating tumor DNA, or ctDNA) suspended in the blood of colorectal cancer patients. To help doctors determine treatment methods, this product provides auxiliary test data to determine the appropriateness for patients with colorectal cancer of the molecularly targeted drags—Cetuximab and Panitumumab (gene recombination)—, using BEAMing technology5 that detects RAS gene mutations to a high degree of sensitivity. Jointly developed between Merck KGaA, Darmstadt, Germany, and our subsidiary Sysmex Inostics, the product received CE Marking certification in March 2016, which indicates the product complies with the European IVD Directive, and is already being used for clinical applications in Europe. For the approval as an in vitro diagnostic reagent in Japan, eight medical facilities were involved in a multi-facility evaluation, including the National Cancer Center Hospital East. Gene testing using this product can be used to provide appropriate treatment opportunities for patients that would have difficulty with testing using conventional tumor tissue. Furthermore, rather than physical biopsies, this type of testing allows samples to be obtained from blood samples in a simple and minimally invasive manner. This helps reduce the physical and mental burden on the patient, shortens the time required from the start of testing, and contributes to the early-stage determination of treatment methods.

Going forward, we plan to launch the OncoBEAM RAS CRC Assay Service, an assay service for colorectal cancer using liquid biopsy to detect RAS gene mutations in the blood, at the Sysmex IMP laboratory, located in the Kobe Biomedical Innovation Cluster. To increase the opportunities for more patients to receive the testing, we plan to apply for Japan’s national insurance coverage for this product.

By providing new cancer diagnostic methods to patients at the earliest possible date, such as the OncoBEAM RAS CRC Kit, as well as the OncoGuideTM NCC Oncopanel System,5 which received insurance coverage in Japan on June 1, 2019 for use in cancer genome profiling, Sysmex aims to take the global lead in realizing personalized medicine, contributing to patient quality of life and the advancement of healthcare.

Terminology

OncoBEAM:
The name of Sysmex’s technology to detect minute gene mutations circulating in the blood with a high degree of sensitivity using BEAMing technology. BEAMing technology is an acronym for "bead, emulsion, amplification and magnetics", a gene analysis method developed at Johns Hopkins University combining digital PCR and flow cytometry technologies for highly sensitive analysis of genetic mutations.

RAS gene:
As the likelihood is high that patients with RAS gene (KRAS/NRAS gene) mutations will not benefit (prolongation of life, tumor reduction) from the administration of anti-EGFR drugs, companion diagnostics may be performed to treat the gene mutation first.

According to the results of multi-facility evaluation, determination results using this method are on a par with those of conventional RAS gene mutation testing using tumor tissue. Source: British Journal of Cancer volume 120, pages 982–986 (2019)

The Guidance on Genetic Testing in the Treatment of Coloretal Cancer Vol. 4.1 (May 2019), published by the Japanese Society of Medical Oncology, indicates the necessity of using liquid biopsy for colorectal cancer and the clinical utility of ctDNA testing.

Mahendra Deonarain, Antikor’s CEO and visiting Reader in Antibody Technology at Imperial College London where Antikor has its roots, commented: "We believe we have a platform that is tailored to make an impact in an area of major unmet medical need, and with EssexBio’s considerable commercial and clinical expertise, we now have the opportunity for translating the promised advantages of Antikor’s proprietary products into clinical benefit."

"We are excited to have established a strong alliance with Antikor", said Malcolm Ngiam, President of Essex Bio-Investment, "Fragment-Drug Conjugate is an innovative approach with the potential to overcome many of the challenges faced by current treatment methods. The research and commercial partnership with Antikor is an important step towards developing first-in-class treatment for cancer."

Antikor’s novel technology platform will enrich Essex’s research pipeline and is aligned with EssexBio’s long-term research and commercial strategy.

Antibody Fragment-Drug Conjugates (FDCs)

Antibody Fragment-Drug Conjugates (FDCs, also called immuno-conjugates) combine the pharmacological potency of highly cytotoxic drugs with the high specificity of an antibody against tumour-associated targets. FDCs comprise much smaller antibody fragments (single-chain scFvs) than ‘whole’ antibody drug conjugates (ADCs). FDCs are relatively easy to discover and can be bioengineered for multiple drug-molecule conjugation, leading to higher loadings than has so far been achieved with whole mAbs. FDCs demonstrate superior tumour penetration and rapid elimination from normal tissues, without running the risk of problems with product manufacturing or stability.1 As a next-generation cancer therapy that can overcome the many limitations of existing treatment options, FDCs have exciting market potential, with predicted sales of drug-conjugates of over $18 billion by 2022.2

"In recent months, we’ve made substantial progress across our pipeline of novel candidates from our two Phase 3 GIST trials with ripretinib to the addition of DCC-3116, a potential first-in-class autophagy inhibitor aimed at treating mutant RAS cancers," said Steve Hoerter, President and Chief Executive Officer of Deciphera. "Later this month, we expect to announce top-line data from the INVICTUS pivotal Phase 3 clinical study, the results of which, if favorable, could serve as the basis for our first new drug application, or NDA, filing. We also recently established our first license agreement for ripretinib outside of the U.S., which we believe reflects the growing recognition that ripretinib has the potential to alter the treatment landscape for patients with GIST."

Recent Pipeline Updates

Ripretinib
Deciphera expects to report top-line data from the INVICTUS pivotal Phase 3 clinical study evaluating the safety and efficacy of ripretinib, the Company’s investigational broad-spectrum KIT and PDGFRα inhibitor, in fourth-line and fourth-line plus GIST patients in August 2019. The Company is building its commercial and medical affairs capabilities to support the planned launch of ripretinib in the United States, if approved.
In June 2019, the U.S. Food and Drug Administration (FDA) granted Fast Track Designation for ripretinib for the investigation of the treatment of patients with advanced GIST who have received prior treatment with imatinib, sunitinib and regorafenib.
Deciphera continues to activate sites and enroll patients in the INTRIGUE Phase 3 clinical study comparing ripretinib to sunitinib for the treatment of second-line GIST patients who have previously received imatinib. As of July 26, 2019, 45 sites have been activated.
Rebastinib
Deciphera previously announced the initiation of an open-label, multicenter, Phase 1b/2 combination study of rebastinib, the Company’s investigational small molecule switch control inhibitor of TIE2 kinase, with carboplatin in patients with advanced or metastatic solid tumors.
Deciphera completed enrollment of 43 patients in Part 1 of the Phase 1b/2 combination study of rebastinib with paclitaxel. Part 2 of the Phase 1b/2 study is now enrolling patients. The Company expects to report initial data from Part 1 of this study in the second half of 2019.
DCC-3014
The Company plans to present updated data from the ongoing dose escalation portion of the Phase 1 clinical study of DCC-3014, the Company’s investigational small molecule switch control inhibitor of CSF1R, in patients with advanced malignancies, in the second half of 2019.
The Company continues to enroll patients diagnosed with tenosynovial giant cell tumors (TGCT) in the Phase 1 study evaluating DCC-3014.
DCC-3116
In June 2019, Deciphera announced the addition of a new candidate to its pipeline, DCC-3116, a potential first-in-class small molecule designed to inhibit cancer autophagy, a key tumor survival mechanism, by inhibiting the ULK kinase. Subject to favorable investigational new drug (IND)-enabling studies and filing and activation of an IND, expected in mid-2020, Deciphera intends to develop DCC-3116 for the potential treatment of mutant RAS cancers in combination with inhibitors of downstream RAS effector targets including RAF, MEK, or ERK inhibitors as well as with direct inhibitors of mutant RAS.
Corporate Updates

Ripretinib License Agreement for Greater China.
In June 2019, Deciphera announced an exclusive license agreement with Zai Lab (Shanghai) Co., Ltd. (Zai) to advance the development and commercialization of ripretinib in Greater China, including mainland China, Hong Kong, Macau and Taiwan. Under the terms of the agreement, Deciphera has received an upfront cash payment of $20 million and will be eligible to receive up to $185 million in potential development and commercial milestone payments, including $5 million for an INTRIGUE study-related milestone the Company achieved. In addition, Zai will be obligated to pay Deciphera royalties ranging from low to high teens on annual net sales of ripretinib in Greater China.
New Member of the Board of Directors
In July 2019, Deciphera announced the appointment of Susan L. Kelley, M.D. to its Board of Directors. Dr. Kelley has over 25 years of experience across all stages of oncology drug research and development.
Second Quarter 2019 Financial Results

Cash Position: As of June 30, 2019, cash, cash equivalents and marketable securities were $225.4 million, compared to cash and cash equivalents of $293.8 million as of December 31, 2018. Deciphera expects its cash, cash equivalents and marketable securities as of June 30, 2019, along with the $20.0 million up-front payment from the Company’s recent license agreement with Zai received in the third quarter of 2019, will enable the Company to fund its operating expenses, capital expenditure requirements and debt service payments into the fourth quarter of 2020. This excludes any potential milestone or royalty payments, if any, under Deciphera’s license agreement with Zai.
Revenue: Revenue for the second quarter of 2019 was $25.0 million which was related to the Company’s exclusive license agreement with Zai to advance the development and commercialization of ripretinib in Greater China. Deciphera recognized license revenue of $20.0 million for an upfront fee and $5.0 million for a development milestone related to the INTRIGUE study.
R&D Expenses: Research and development expenses for the second quarter of 2019 were $34.8 million, compared to $18.0 million for the same period in 2018. The increase was primarily due to the INTRIGUE Phase 3 clinical study in second-line GIST, which the Company initiated in December 2018, and to the INVICTUS Phase 3 clinical study in fourth-line and fourth-line plus GIST, which the Company initiated in January 2018. The Company also incurred costs related to other supporting clinical trials for ripretinib. Additionally, expenses related to the rebastinib program increased primarily as a result of an increase in clinical trial costs related to the Phase 1b/2 trial of rebastinib in combination with paclitaxel, which the Company initiated in October 2018, and the second Phase 1b/2 clinical trial of rebastinib in combination with carboplatin, which the Company initiated in January 2019. Personnel-related costs increased $4.0 million primarily due to increased headcount and stock-based compensation expense in research and development functions. Personnel-related costs for the second quarters of 2019 and 2018 included non-cash stock-based compensation expense of $1.8 million and $1.0 million, respectively. Facility-related and other costs included in unallocated expenses increased $2.3 million primarily due to increased consultant fees and other costs in connection with our early-stage drug discovery programs.
G&A Expenses: General and administrative expenses for the second quarter of 2019 were $13.2 million, compared to $4.5 million for the same period in 2018. The increase was primarily due to an increase in professional, consultant and various advisory fees, including those related to commercialization preparedness. Non-cash stock-based compensation was $2.3 million and $1.2 million for the second quarters of 2019 and 2018, respectively. The increase in non-cash stock-based compensation expense was primarily related to the granting of additional employee stock option awards.
Net Loss: For the second quarter of 2019, Deciphera reported a net loss of $21.5 million, or $0.56 per share, compared with a net loss of $21.7 million, or $0.65 per share, for the same period in 2018.

Transgene Provides Update on PHOCUS Study of Pexa-Vec in Liver Cancer Following Planned Interim Futility Analysis

On August 2, 2019 Transgene (Paris:TNG), a biotech company designing and developing virus-based immunotherapies for the treatment of solid tumors, reported that the independent Data Monitoring Committee ("IDMC") of the PHOCUS study of Pexa-Vec in Liver Cancer has completed a planned interim futility analysis. Sillajen has informed Transgene of the IDMC’s recommendation to stop enrolment in the study, as the study is unlikely to meet its primary objective by the time of the final analysis (Press release, Transgene, AUG 2, 2019, View Source [SID1234538100]). SillaJen has not reported safety concerns. Transgene will provide an update in an upcoming conference call.

The PHOCUS trial is a Phase 3 clinical trial evaluating the oncolytic immunotherapy Pexa-Vec for advanced liver cancer patients who have not received prior systemic treatment for their cancer. The study is being conducted by Transgene’s partner, SillaJen.

In the PHOCUS study, patients were randomized to one of two treatment groups: one receiving Pexa-Vec followed by sorafenib and one receiving sorafenib alone. The primary objective of the study was to determine the overall survival of patients treated with Pexa-Vec, followed by sorafenib versus sorafenib alone. Secondary objectives included safety as well as assessments for tumor responses between the two groups as measured by the following endpoints: time to progression, progression-free survival, overall response rate and disease control rate.

About Pexa-Vec
Pexa-Vec (JX-594) is an oncolytic immunotherapeutic based on an oncolytic vaccinia virus armed with a GM-CSF gene that promotes an anti-tumor immune response. Pexa-Vec is designed to selectively target and destroy cancer cells through three different mechanisms of action: selectively destroy cancer cells through the direct lysis (breakdown) of cancer cells through viral replication, reduce the blood supply to tumors through vascular disruption, and stimulate the body’s immune response against cancer cells.
In a Phase 2 study, results of patients with advanced liver cancer showed that patients receiving the high dose had a statistically significant clinical improvement in terms of overall survival compared to the group receiving the low dose. Median overall survival was respectively 14.1 months in the high-dose group and 6.7 months in the low-dose group, which compares favorably with current approved treatments. (Heo J. et al., Nature Medicine, March 2013, doi: 10.1038/nm.3089)
Transgene has exclusive rights to develop and commercialize Pexa-Vec for the treatment of solid tumors in Europe. Its partner SillaJen, Inc. is focused on developing Pexa-Vec for the North American market and has also granted exclusive development and commercial rights to Pexa-Vec in Hong Kong and The People’s Republic of China to Lee’s Pharmaceutical.

BioMarin Announces Second Quarter 2019 Financial Results

On August 1, 2019 BioMarin Pharmaceutical Inc. (NASDAQ: BMRN) (BioMarin or the Company) reported financial results for the second quarter ended June 30, 2019 (Press release, BioMarin, AUG 1, 2019, View Source [SID1234538004]).

Total Net Product Revenues for the second of quarter 2019 increased to $379.1 million, compared to $367.8 million for the second quarter of 2018. The increase in Net Product Revenues was attributed to the following:

Palynziq Net Product Revenues during the second quarter of 2019 totaled $18.8 million driven primarily by new patients initiating therapy in the U.S. as the product launched in the third quarter of 2018. Palynziq received approval from the U.S. Food and Drug Administration (FDA) in May 2018 and from the European Medicines Agency (EMA) in May 2019. EU commercial sales are expected to commence in the third quarter of 2019; and

Naglazyme Net Product Revenues increased by $7.1 million, or 8%, primarily due to increased sales volume driven by government ordering patterns from certain Latin American and European countries, partially offset by

Aldurazyme Net Product Revenues decreased $18.2 million, due to the timing of customer acceptance for product shipped to Genzyme in the second quarter for which no revenue was recognized as of June 30, 2019. Aldurazyme revenue recognition is based on timing of Genzyme acceptance of product shipment. Approximately $23.0 million of Aldurazyme revenue that was shipped in the second quarter is expected to be recognized in the third quarter of 2019 once product has been accepted by Genzyme. The delay was due to a change in the location where Genzyme receives product. Genzyme’s Aldurazyme revenues, as provided to BioMarin by Genzyme, increased $11.6 million or 9% during the six months ended June 30, 2019, compared to the same period in 2018. Full-year total Aldurazyme revenues are expected to be consistent with full-year Aldurazyme revenues in prior years and in the $100.0 to $120.0 million range; and

Vimizim Net Product Revenues decreased by $4.9 million, or 4%, primarily due to decreased sales volume driven by government ordering patterns in certain Latin American, Middle Eastern and European countries.
The increase in GAAP Net Loss for the second quarter of 2019, compared to the same period in 2018 was primarily due to the following:

higher research and development (R&D) expense related to preclinical activities for our PKU gene therapy development program and clinical activities for our valoctocogene roxaparvovec and vosoritide development programs, offset by decreased R&D expense related to Palynziq for which we began capitalizing manufacturing costs upon FDA approval in May 2018 and a decrease in tralesinidase alfa clinical manufacturing costs. R&D expenses in the quarter were consistent with 2019 guidance despite the acceleration of the valoctocogene roxaparvovec development program and subsequent activities implemented to pursue an expedited regulatory path forward; and

higher intangible asset amortization related to the Palynziq in-process research and development assets that were placed into service following EU approval in May 2019; and

higher selling, general and administrative (SG&A) expense in support of the EU commercial launch and continued U.S. expansion of Palynziq, pre-commercialization activities related to valoctocogene roxaparvovec and increased general and administrative expense primarily attributed to personnel-related costs resulting from increased headcount to support our growth; partially offset by;

increased gross profits of $12.9 million driven by increased product sales.
The increase in GAAP Net Loss for the second quarter of 2019 did not affect the Company’s full-year GAAP Net Loss Guidance, which remains unchanged.
Non-GAAP Income for the second quarter of 2019 decreased $2.8 million, or 14%, to $17.1 million, compared to $19.9 million for the same period in 2018. The decrease in Non-GAAP Income for the quarter, compared to the same period in 2018, was attributed to higher R&D expense and SG&A expense, partially offset by increased gross profit from sales as described above. The decrease in Non-GAAP Income for the second quarter of 2019 did not affect the Company’s full-year Non-GAAP Income Guidance, which remains unchanged.
As of June 30, 2019, BioMarin had cash, cash equivalents and investments totaling approximately $1.1 billion, as compared to $1.3 billion on December 31, 2018.
Commenting on second quarter results, Jean-Jacques Bienaimé, Chairman and Chief Executive Officer of BioMarin, said, "During the first half of 2019 we laid the foundation for a number of significant milestones anticipated over the coming months. We recently announced our plans to submit marketing applications for valoctocogene roxaparvovec gene therapy for severe hemophilia A in both the United States and Europe. We expect to submit both applications in the fourth quarter of this year based on recent interactions with health authorities in those regions. We are pleased

to have the opportunity to initiate the first review of a marketing application for any type of hemophilia indication with a gene therapy product. With valoctocogene roxaparvovec people with severe hemophilia A may soon have the opportunity to experience improved quality of life, including consequences of bleeding, physical functioning, role functioning, emotional impact, treatment concern, and worry. We are very grateful that health authorities are aligned in their focus to expedite the review of this potentially transformative treatment option given the unmet need with current standard of care."
Mr. Bienaimé continued, "Phase 3 results from another potential commercial product, vosoritide for the treatment of achondroplasia, are expected to read-out at the end of this year. Our newest study, a global Phase 2 with vosoritide in infants and young children (less than 60 months old) with achondroplasia is enrolling very well. We expect all subjects ages 6 months through 5 years to be enrolled by year-end. We have been very pleased with the high-level of enthusiasm from families wanting to participate in this program and look forward to starting enrollment in the youngest cohort, infants up to 6 months old, later this year. Another very significant opportunity that is gaining momentum is the global commercialization of Palynziq. We have been very pleased with the pace of the U.S. launch, as we ended the second quarter with 551 patients on reimbursed Palynziq, and an additional 158 naive patients having completed enrollment and awaiting their first injection. Building on this success and as part of our strategy to increase our leadership in the PKU market, we anticipate the submission of an investigational new drug application (IND) and/or a clinical trial application (CTA) for BMN 307, our gene therapy product for PKU, in the second half of 2019. BMN 307 demonstrated lifetime normalization of Phe in a validated PKU mouse model, and as a result, we believe it has the potential to be an important new treatment and market expander as part of our PKU franchise."
2019 Full-Year Financial Guidance unchanged (in millions, except %)

Key Program Highlights

Valoctocogene roxaparvovec gene therapy for hemophilia A: On July 8, the Company announced that based on recent meetings with health authorities in the U.S. and Europe, it plans to submit marketing applications to both the FDA and the European Medicines Agency (EMA) in the fourth quarter of 2019 for its investigational gene therapy, valoctocogene roxaparvovec, for adults with severe hemophilia A.

These submissions will be based on the updated three-year Phase 1/2 data and the recently completed Phase 3 interim analysis of patients treated with valoctocogene roxaparvovec material from the to-be-commercialized process. Both submissions are expected to represent the first time a gene therapy product for any type of hemophilia indication will be reviewed for marketing authorization by health authorities.

The Company has chosen to cease development of the 4e13 vg/kg dose of valoctocogene roxaparvovec given the overwhelming preference by patients to be treated with the 6e13 vg/kg dose. Enrollment continues in the GENEr8-1 Phase 3 study and the 52 week results are anticipated at the end of 2020.

Palynziq for PKU: Palynziq, an injection to reduce blood Phe concentrations in adult patients with PKU, was added to BioMarin’s commercial product portfolio upon its U.S. approval May 2018. As of June 30, 2019, 551 patients were on reimbursed Palynziq, with an additional 158 naïve patients enrolled and awaiting their first treatment with commercial Palynziq. Of the 551 patients on therapy at the end of the second quarter, 410 were formerly naïve patients and 141 transitioned from clinical studies. Of the 125 PKU clinics in the U.S., 92 unique clinics had at least one complete patient enrollment in the REMS program as of June 30, 2019.
On May 6, 2019, the European Commission (EC) granted marketing authorization for Palynziq at doses of up to 60 milligrams once daily, to reduce blood Phe concentrations in patients with PKU aged 16 and older, who have inadequate blood Phe control (blood Phe levels greater than 600 micromol/L) despite prior management with available treatment options. In addition, the EC acknowledged that the Phase 3 trial and extension study is suggestive of an improvement in inattention and mood symptoms.

Vosoritide for children with achondroplasia: On June 18, 2019, the New England Journal of Medicine published the 42 month results from the Phase 2 study with vosoritide in children ages 5 to 14 years. The results also appeared in the July 4 printed issue. BioMarin expects to have over 5 years of clinical data from this Phase 2 study to corroborate maintenance of effect at the time of anticipated marketing application submissions.
The Company expects top line results from the ongoing global, Phase 3 study by year-end 2019. The vosoritide development program includes four distinct areas of focus to support global approval, including a large contemporaneous natural history study which is underway. The global Phase 3 study, which is fully enrolled, is a randomized, placebo-controlled study of vosoritide in approximately 110 children with achondroplasia between the ages of 5 to 14 years.
In 2018, BioMarin began a global Phase 2 study with vosoritide in infants and young children (newborn to 60 months old) with achondroplasia, to determine the impact of treatment in this age group. Three cohorts, segmented by age, are being enrolled in this study. Cohort 1 includes children ages 24 to 60 months old and has completed enrollment. Cohort 2 includes children ages 6 to 24 months old and is expected to complete enrollment by year-end. The Company plans to begin enrolling infants up to 6 months old by year-end.

Tralesinidase alfa (formerly referred to as BMN 250) for MPS IIIB (Sanfilippo Syndrome, Type B): Tralesinidase alfa is currently being evaluated in ongoing natural history and clinical trials. Previously, encouraging signs of biochemical and clinical efficacy have been suggested. Trials are ongoing to collect further data in regard to the untreated natural history of the condition, as well as biochemical and clinical outcomes of therapy.

BMN 307 gene therapy product candidate for phenylketonuria (PKU): As previously announced, the Company expects to submit an IND and/or a CTA for a gene therapy product for the treatment of PKU in the second half of 2019. At R&D Day 2018, BioMarin shared data with BMN 307 that demonstrated a lifetime Phe correction sustained at 80 weeks in preclinical mouse models. BMN 307 is an AAV vector containing the DNA sequence that codes for the phenylalanine hydroxylase enzyme that is deficient in people with PKU.
