"Our commercial team is doing a superb job with the launch of ARCALYST in recurrent pericarditis," said Sanj K. Patel, Chief Executive Officer and Chairman of the Board of Kiniksa. "Feedback received from physicians and patients highlights the transformational potential of ARCALYST for patients suffering from recurrent pericarditis. We have seen strong uptake and look forward to using this momentum to accelerate broader adoption across this underserved population."

"We are executing on the development of our clinical-stage pipeline," said John F. Paolini, MD, PhD, Chief Medical Officer of Kiniksa. "The potential broad utility of mavrilimumab across multiple indications is increasingly promising, and we expect data from our Phase 3 clinical trial in COVID-19-related ARDS in the first quarter of 2022. We are enrolling a Phase 2b clinical trial of vixarelimab in prurigo nodularis and believe vixarelimab has the potential to make a meaningful impact on these patients’ lives by addressing both the pruritus and the skin nodules associated with this devastating disease. KPL-404, our anti-CD40 program, has potential across a range of autoimmune diseases, and we plan to initiate a Phase 2 proof-of-concept clinical trial in rheumatoid arthritis in the fourth quarter of this year."

Portfolio Activity
ARCALYST (IL-1α and IL-1β cytokine trap)

ARCALYST net revenue in the second quarter of 2021 was $7.7 million.
The second quarter of 2021 represented Kiniksa’s first quarter of ARCALYST sales. ARCALYST became commercially available through Kiniksa on April 1st, 2021.
Greater than 100 physicians who did not participate in Phase 3 RHAPSODY prescribed ARCALYST to at least one recurrent pericarditis patient.
Greater than 65% of all recurrent pericarditis enrollments came from physicians practicing outside of the 12 Phase 3 RHAPSODY clinical trial sites in the U.S.
Greater than 90% of completed new patient enrollment cases were approved for coverage under the payer medical exceptions process.
Kiniksa continues to expect that the majority of payers will establish coverage policies within six months and that almost all payers will update their coverage policies within a year from launch.
Kiniksa OneConnectTM provided access, initiation and ongoing support for existing ARCALYST cryopyrin-associated periodic syndromes (CAPS) and deficiency of IL-1 receptor antagonist (DIRA) patients transitioning to Kiniksa product as well as new ARCALYST patients for all approved indications.
Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)

Kiniksa’s interactions with the U.S. Food and Drug Administration (FDA) resulted in defined paths for Phase 3 development of mavrilimumab in COVID-19-related acute respiratory distress syndrome (ARDS) and in giant cell arteritis (GCA).
Kiniksa reported additional data from the Phase 2 portion of the Phase 2/3 clinical trial of mavrilimumab in patients with severe COVID-19-related ARDS.
Follow-up overall survival data from the cohort of non-mechanically ventilated patients through Day 90 demonstrated persistent clinical effect, confirming and extending the previously-reported Day 29 data.
Day 29 data from the cohort of mechanically-ventilated patients did not show a reduction in death.
Kiniksa continues to enroll non-mechanically ventilated patients in the Phase 3 clinical trial of mavrilimumab in COVID-19-related ARDS.
Kiniksa discontinued enrolling mechanically-ventilated patients in the Phase 3 trial.
Kiniksa expects data from the Phase 3 trial in non-mechanically-ventilated patients in the first quarter of 2022.
Vixarelimab (monoclonal antibody inhibitor of signaling through OSMRβ)

Kiniksa continues to enroll patients in a placebo-controlled Phase 2b clinical trial of vixarelimab in prurigo nodularis, evaluating a range of once-monthly dose regimens via subcutaneous (SC) injection.
The primary efficacy endpoint is the percent change from baseline in the weekly-average Worst-Itch Numeric Rating Scale at Week 16.
KPL-404 (monoclonal antibody inhibitor of the CD40 and CD154 interaction)

Kiniksa plans to initiate a placebo-controlled Phase 2 proof-of-concept clinical trial of KPL-404 in rheumatoid arthritis in the fourth quarter of 2021.
The planned trial is designed to provide safety data, pharmacokinetic characterization, and efficacy of chronic SC dosing over 12 weeks.
Rheumatoid arthritis was selected for demonstration of KPL-404 proof of concept as it is a well-characterized autoimmune disease with decades of published clinical data across diverse mechanistic classes, allowing for objective evaluation in established endpoints.
The pharmacokinetic lead-in of the planned trial supports characterization of chronic administration of KPL-404 in a patient population and provides optionality to evaluate the therapeutic potential of KPL-404 across a range of other autoimmune diseases with pathologies believed to be mediated by the CD40-CD154 pathway.
Upcoming Scientific Conference Presentations

Kiniksa plans to present additional data from RHAPSODY, the pivotal Phase 3 trial of rilonacept, as well as the study design of the RESONANCE Registry, at the European Society of Cardiology virtual congress, which will be held August 27, 2021 through August 30, 2021. Details of the poster presentations are as follows:
Antonio Brucato, MD, Department of Biomedical and Clinical Science, University of Milan, Fatebenefratelli Hospital, Milan, will present a poster entitled, Health-Related Quality of Life in Patients with Recurrent Pericarditis: Results from RHAPSODY, a Phase 3 Study of Rilonacept.
Alison Reid, PhD, Kiniksa Pharmaceuticals Corp., will present a poster entitled, RESONANCE Registry: Rationale and Design of the Retrospective and Prospective Longitudinal, Observational Registry in Pediatric and Adult Patients with Recurrent Pericarditis.

2021 Outlook
Based on results in the first half of 2021, the Company is increasing its guidance for the full year 2021 and now expects revenue between $61-$63 million, compared to its prior guidance of $55-$57 million.
"In the second quarter, Apollo continued to build momentum by delivering strong financial performance, including record revenue and increased gross margin," said Chas McKhann, Apollo’s Chief Executive Officer. "We also achieved a number of strategic milestones, including sequential growth in our ESS and IGB business lines, positive early indication on MERIT study outcomes and a significant expansion of our X-Tack user base. We believe that these accomplishments plus additions to our leadership team and commercial organization position us well for the future."
Second Quarter Results
Total revenues were $16.6 million for the second quarter of 2021, a new record for the Company’s endoscopy business. Revenue increased $11.0 million or 194% compared to $5.6 million in revenue during the second quarter of 2020 which was impacted by the onset of the COVID-19 pandemic.
Compared to the second quarter of 2020, total ESS product sales increased $7.0 million or 196% and total IGB product sales increased $4.0 million or 220% due to the improvement in demand for our products as the impact of the pandemic continued to dissipate.
Gross margin increased to 55% for the second quarter of 2021 from 43% in the second quarter of 2020 due to higher sales, improved mix of higher variable gross margin products including the new X-Tack device, and unabsorbed overhead costs from reduced production volumes in the prior year quarter as a result of the COVID-19 pandemic.
Total operating expenses increased $7.6 million compared to the second quarter of 2020. The increase was due to the normalization of temporary cost controls that we implemented in response to the pandemic. It also was impacted by higher stock-based compensation expense in the second quarter of 2021.
Net loss for the second quarter of 2021 was $3.0 million compared to $6.3 million for the second quarter of 2020. Excluding the $2.9 million gain on forgiveness of the PPP loan for the second quarter of 2021, and non-cash stock-based compensation expense of $2.5 million and $0.5 million for the second quarter of 2021 and 2020, respectively, net loss for the second quarter of 2021 improved 42% from the second quarter of 2020.
Cash, cash equivalents and restricted cash were $31.2 million as of June 30, 2021, representing a decrease of $1.4 million in cash for the quarter.
* Excluding divested product lines.

Non-GAAP Financial Measures
To supplement our financial results, we are providing a non-GAAP financial measure, product sales percentage change in constant currency, which removes the impact of changes in foreign currency exchange rates that affect the comparability and trend of revenues compared to the same period of the prior year. Product sales percentage change in constant currency is calculated by translating current foreign currency sales at last year’s exchange rate. This supplemental measure of our performance is not required by, and is not determined in accordance with GAAP.
We believe the non-GAAP financial measure included herein is helpful in understanding our current financial performance. We use this supplemental non-GAAP financial measure internally to understand, manage and evaluate our business, and make operating decisions. We believe that making non-GAAP financial information available to investors, in addition to GAAP financial information, may facilitate more consistent comparisons between the company’s performance over time with the performance of other companies in the medical device industry, which may use similar financial measures to supplement their GAAP financial information. However, our non-GAAP financial measure is not meant to be considered in isolation or as a substitute for the comparable GAAP metric.

On August 3, 2021 Ambrx (NYSE: AMAM), a clinical stage biopharmaceutical company using an expanded genetic code technology platform to create Engineered Precision Biologics, reported the first patient has been dosed in a Phase 1, multicenter, open-label, dose-escalation, and dose expansion study to evaluate the safety, pharmacokinetics (PK), and anti-tumor activity of ARX517 in subjects with prostate specific membrane antigen (PSMA) expressing tumors found in prostate, pancreatic, lung and ovarian cancers (Press release, Ambrx, AUG 3, 2021, View Source [SID1234585640]).

ARX517 is an anti-PSMA antibody drug conjugate (ADC) that demonstrated activity in both enzalutamide sensitive and resistant preclinical models for prostate cancer while demonstrating favorable PK and toxicity profiles in IND-enabling GLP toxicity studies.

"I am excited to announce that we dosed our first patient in our Phase 1 trial, and thus have taken the first steps in evaluating the potential clinical benefit of ARX517 in cancer patients with tumors overexpressing PSMA," said Feng Tian, Ph.D., Chairman of the Board, President and CEO of Ambrx. "ARX517 is the second ADC in our internal pipeline to enter the clinic, which I believe speaks to the broad applicability and productivity of our technology platform. I look forward to updating you on the progression of this trial."

The Phase 1 trial will be a multi-center, open-label, dose escalation and dose expansion study. This trial, referred to as APEX-01, is designed to assess the safety, tolerability and PK profile, as well as the anti-tumor activity, of ARX517 as a monotherapy. The trial will enroll up to 76 patients with advanced solid tumors whose diseases have failed prior standard therapies.

About PSMA, prostate cancer and other solid tumors

PSMA has been found highly expressed in prostate cancer, particularly in metastatic castration-resistant prostate cancer (mCRPC). Additionally, PSMA has been found in a variety of other solid tumors. Prostate cancer represents a significant unmet need and sizable market opportunity. There were 1.3 million new cases of prostate cancer with five-year survival rates of approximately 27% and 359,000 associated deaths worldwide in 2018. For men, prostate cancer is the second most frequent cancer and the fifth leading cause of cancer death. The global market for prostate cancer therapies was estimated to be $9.3 billion in 2018 and is forecast to grow to $12.8 billion by 2028. While non-ADC therapies are available to treat mCRPC, there is no approved therapy specifically targeting PSMA to treat prostate cancer.

Corporate Development

On May 5, 2021, the Company completed the acquisition of GW Pharmaceuticals plc (GW) for a total value of approximately $7.2 billion, or $6.8 billion net of GW cash. The Company secured $5.35 billion of financing to fund the GW transaction. The financing structure supports the Company’s plans for rapid deleveraging to its stated targets while also continuing to make investments to grow the business. The combined company is a leader in neuroscience with a global commercial and operational footprint, well positioned to maximize the value of its diversified portfolio.

Neuroscience

Oxybate (Xyrem and Xywav):

Net product sales for the combined oxybate business increased 3% to $458.3 million in the second quarter of 2021 compared to the same period in 2020.
Average active oxybate patients on therapy were approximately 15,900 in the second quarter of 2021, an increase of approximately 5% compared to the same period in 2020.
Xywav (calcium, magnesium, potassium, and sodium oxybates) oral solution:

Xywav net product sales were $124.2 million in the second quarter of 2021.
There were approximately 5,100 active patients on Xywav exiting the second quarter of 2021.
In June 2021, FDA recognized seven years of Orphan Drug Exclusivity for Xywav.
FDA published its summary of clinical superiority findings for Xywav stating that Xywav is clinically superior to Xyrem by means of greater safety because Xywav provides a greatly reduced chronic sodium burden compared to Xyrem, and that the differences in the sodium content of the two products at the recommended doses will be clinically meaningful in reducing cardiovascular morbidity in a substantial proportion of patients for whom the drug is indicated.
The Company has achieved its goal of obtaining broad payer coverage, having entered into agreements with all three of the largest pharmacy benefit managers.
Xyrem (sodium oxybate) oral solution:

Xyrem net product sales decreased 25% to $334.2 million in the second quarter of 2021 compared to the same period in 2020.
Xywav in Idiopathic Hypersomnia

FDA has granted Priority Review Designation and accepted the supplemental New Drug Application (sNDA) for Xywav in adult patients with idiopathic hypersomnia (IH). The Prescription Drug Fee User Act (PDUFA) target date for an FDA decision has been set for August 12, 2021, which is in line with the Company’s objective of launching in the fourth quarter of 2021 following risk evaluation and mitigation strategy (REMS) implementation.
Epidiolex/Epidyolex (cannabidiol):

Epidiolex/Epidyolex net product sales were $109.5 million in the second quarter of 2021. This includes sales from May 5, 2021, the closing date of the GW Acquisition.
On an unaudited pro forma basis, net product sales in the second quarter of 2021 increased by 32% to $155.9 million compared to the same period in 2020.
The Company expects to initiate a Phase 3 pivotal trial of Epidiolex for Epilepsy with Myoclonic-Atonic Seizures (EMAS), also known as Doose syndrome, in the first half of 2022. EMAS represents the fourth target indication for Epidiolex.
Sunosi (solriamfetol):

Sunosi net product sales increased by 41% to $12.1 million in the second quarter of 2021 compared to the same period of 2020.
In the second quarter of 2021, U.S. prescriptions increased by 25% compared to the first quarter of 2021.
Nabiximols:

The Company expects to initiate the third Phase 3 nabiximols clinical trial in multiple sclerosis (MS)-related spasticity this year.
The two ongoing Phase 3 clinical trials in MS-related spasticity continue to progress.
JZP385:

JZP385, a highly selective modulator of T-type calcium channels, is in clinical development for the potential treatment of essential tremor.
The Company expects to initiate a Phase 2b trial in late 2021.
JZP150:

JZP150, a fatty acid amide hydrolase (FAAH) inhibitor, is in clinical development for the potential treatment of post-traumatic stress disorder.
The Company expects to initiate a Phase 2 trial in late 2021.
Oncology

Zepzelca (lurbinectedin):

Zepzelca net product sales were $55.9 million in the second quarter of 2021.
Sequential demand growth over the first two quarters of 2021 was 8% and 9% respectively, offset mainly by reduced inventory holding by distributors.
Robust Zepzelca development program planned:
The Company’s partner, PharmaMar, plans to initiate a confirmatory trial in second-line small cell lung cancer (SCLC) later this year. If positive, this trial would confirm the benefit of Zepzelca in the treatment of SCLC when patients progress following first-line treatment with a platinum-based regimen.
The Company is collaborating with Roche to initiate a Phase 3 pivotal clinical trial in first-line extensive stage SCLC in combination with immunotherapy this year.
The Company expects to initiate a Phase 2 basket trial in early 2022 to explore lurbinectedin monotherapy in patients with select advanced or metastatic solid tumors. Cohorts will include advanced urothelial cancer, large cell neuroendocrine tumor of the lung, and homologous recombinant deficient positive (HRD+) cancers.
The Company has initiated a Phase 4 observational study to collect real world safety and outcome data in adult Zepzelca monotherapy patients with extensive stage small cell lung cancer who progress on or after prior platinum-containing chemotherapy.
Rylaze (asparaginase erwinia chrysanthemi (recombinant)-rywn):

On June 30, 2021, FDA approved Rylaze under the Real-Time Oncology Review program for use as a component of a multi-agent chemotherapeutic regimen for the treatment of acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL) in pediatric patients one month and older and adult patients who have developed hypersensitivity to E. coli-derived asparaginase.
Rylaze was launched and commercially available in the U.S. on July 15, 2021.
Rylaze is the only recombinant Erwinia asparaginase manufactured product that maintains a clinically meaningful level of asparaginase activity throughout the entire duration of treatment. It was developed by Jazz to address the needs of patients and healthcare providers for an innovative, high-quality Erwinia asparaginase with reliable supply.
Rylaze was granted orphan drug designation for the treatment of ALL/LBL by FDA in June 2021.
The Company will continue to work with FDA and plans to submit additional data in support of a Monday/Wednesday/Friday dosing schedule. Part B of the study is evaluating intravenous administration and is ongoing. The company also plans to submit this data for presentation at a future medical meeting.
The Company anticipates that data from the current development program will support regulatory filings in Europe in 2022 and is currently working with an in-country partner to advance the program for filing, approval and launch in Japan.
Vyxeos (daunorubicin and cytarabine) liposome for injection:

Vyxeos net product sales increased 18% to $31.5 million in the second quarter of 2021 compared to the same period in 2020.
Defitelio (defibrotide sodium) / defibrotide:

Defitelio/defibrotide net product sales increased 13% to $48.1 million in the second quarter of 2021 compared to the same period in 2020.
Erwinaze / Erwinase (asparaginase Erwinia chrysanthemi):

Erwinaze/Erwinase net product sales decreased 13% to $28.3 million in the second quarter of 2021 compared to the same period in 2020.
The Company’s agreement with Porton Biopharma Limited terminated on December 31, 2020. The Company had the right to sell certain Erwinaze inventory post-termination. Sale of this inventory was completed in June 2021.

GAAP net income (loss) for the second quarter of 2021 was ($363.3 million), or ($6.11) per diluted share, compared to $114.8 million, or $2.06 per diluted share, for the second quarter of 2020.

Non-GAAP adjusted net income for the second quarter of 2021 was $240.6 million, or $3.90 per diluted share, compared to $207.3 million, or $3.71 per diluted share, for the second quarter of 2020.

Reconciliations of applicable GAAP reported to non-GAAP adjusted information are included at the end of this press release.

Total revenues increased 34% in the second quarter of 2021 compared to the same period in 2020.

Products launched or acquired since 2019 accounted for 41% of total net product sales in the second quarter of 2021.
Neuroscience net product sales in the second quarter of 2021 increased 28% to $581.9 million compared to the same period in 2020. Oxybate net product sales increased to $458.3 million led by strong Xywav net product sales of $124.2 million partially offset by a decrease in Xyrem net product sales as a result of the strong adoption of Xywav by existing Xyrem patients. Epidiolex/Epidyolex net product sales from the date of acquisition were $109.5 million.
Oncology net product sales in the second quarter of 2021 increased 61% to $163.8 million compared to the same period in 2020 primarily driven by robust Zepzelca net product sales of $55.9 million. Zepzelca launched in the U.S. in July 2020.
Operating expenses changed over the prior year periods primarily due to the following:

Cost of product sales increased in the second quarter of 2021 compared to the same period in 2020, on a GAAP and non-GAAP adjusted basis, primarily due to increased net product sales as a result of the GW Acquisition. In addition, an acquisition accounting inventory fair value step-up expense of $66.0 million impacted GAAP cost of product sales.
Selling, general and administrative (SG&A) expenses increased in the second quarter of 2021 compared to the same period in 2020, on a GAAP and on a non-GAAP adjusted basis, primarily due to an increase in compensation-related expenses driven by higher headcount as a result of the GW Acquisition, increased investment in sales, marketing and launch activities primarily related to Sunosi, Xywav and Zepzelca in the U.S. and the addition of costs related to Epidiolex. SG&A expenses in the second quarter of 2021 on a GAAP basis also included transaction and integration related expenses of $129.5 million related to the GW Acquisition.
Research and development expenses increased in the second quarter of 2021 compared to the same period in 2020, on a GAAP and on a non-GAAP adjusted basis, primarily due to the addition of costs related to clinical programs for Epidiolex, nabiximols and cannabinoids, an increase in costs for JZP385 and an increase in compensation-related expenses due to higher headcount primarily driven by the GW Acquisition.
On a GAAP basis, our income tax provision for the three months ended June 30, 2021, included an expense of $251.4 million arising on the remeasurement of our U.K. net deferred tax liability, which arose primarily in relation to the GW Acquisition, due to a change in the statutory tax rate in the U.K. following enactment of the UK Finance Act 2021. Due to the impact of this expense, our effective tax rate for the three months ended June 30, 2021, on a GAAP basis is not a meaningful metric.
On a non-GAAP basis, the decrease in the effective tax rate in the second quarter of 2021 compared to the same period in 2020 was primarily due to the impact in 2020 of the disallowance of certain interest deductions, provision for the settlement reached with the French tax authorities, and the impact of the change in income mix.
