The Innovation Passport is the entry point for the Innovative Licensing and Access Pathway (ILAP). The goal of ILAP is to accelerate the time to market facilitating patient access to medicines in the U.K. The Innovation Passport application is the first step in the ILAP process, which activates the Medicines and Healthcare products Regulatory Agency (MHRA) and its partner agencies, including the National Institute for Health and Care Excellence (NICE), and the Scottish Medicines Consortium (SMC) and to develop a roadmap for regulatory and development milestones.

"This esteemed acknowledgment underscores our commitment to advancing medicine and delivering transformative solutions for patients," said John Houston, Ph.D., president and chief executive officer at Arvinas. "Arvinas is hopeful our investigational PROTAC ER degrader, vepdegestrant, will have the potential to be an endocrine therapy backbone for ER+/HER2-breast cancer."

"The Innovation Passport designation opens the door for Pfizer and Arvinas to discuss access considerations for potential future indications for vepdegestrant," said Chris Boshoff, M.D., Ph.D., chief oncology research and development officer and executive vice president at Pfizer. "We look forward to an ongoing dialogue with regulators, health technology assessment agencies and other partners, supporting a timely review as we aim to bring this potential medicine to patients as quickly as possible."

Multiple Phase 1, 2, and 3 studies with vepdegestrant are enrolling globally, including the VERITAC-2 Phase 3 2L/3L clinical trial of vepdegestrant as a monotherapy for the treatment of patients with ER+/HER2- metastatic breast cancer, which is anticipated to complete enrollment in 2024. Arvinas and Pfizer recently initiated the study lead-in of the VERITAC-3 Phase 3 trial of vepdegestrant and palbociclib as a first-line treatment in patients with ER+/HER2- locally advanced or metastatic breast cancer. The study lead-in will identify the dose of palbociclib for the randomized portion of the study. The companies also plan to submit additional data from the Phase 1b combination trial with palbociclib at a medical congress during the second half of 2023.

About ILAP
The U.K. Medicines and Healthcare products Regulatory Agency (MHRA) launched ILAP at the start of 2021 in order to accelerate the development and access to promising medicines in the early stages of development. The pathway, part of the UK’s plan to attract life sciences development in the post-Brexit era, features enhanced input and interactions with MHRA and other stakeholders. Other benefits of ILAP include access to a range of development tools, such as the potential for a 150-day accelerated Marketing Authorization Application (MAA) assessment, rolling review and a continuous benefit risk assessment. More information about ILAP can be found here.

About vepdegestrant (ARV-471)
Vepdegestrant is an investigational, orally bioavailable PROTAC protein degrader designed to specifically target and degrade the estrogen receptor (ER) for the treatment of patients with early and locally advanced or metastatic ER positive/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. Use of vepdegestrant in the ongoing and planned clinical trials will continue to monitor and evaluate patient safety and anti-tumor activity.

In preclinical studies, vepdegestrant demonstrated up to 97% ER degradation in tumor cells, induced robust tumor shrinkage when dosed as a single agent in multiple ER-driven xenograft models, and showed increased anti-tumor activity when compared to a standard of care agent, fulvestrant, both as a single agent and in combination with a CDK4/6 inhibitor. In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will equally share worldwide development costs, commercialization expenses, and profits.

U.S. Important Safety Information for SYFOVRE (pegcetacoplan injection)

CONTRAINDICATIONS


SYFOVRE is contraindicated in patients with ocular or periocular infections, and in patients with active intraocular inflammation.

WARNINGS AND PRECAUTIONS


Endophthalmitis and Retinal Detachments


Intravitreal injections, including those with SYFOVRE, may be associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering SYFOVRE to minimize the risk of endophthalmitis. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately.


Neovascular AMD


In clinical trials, use of SYFOVRE was associated with increased rates of neovascular (wet) AMD or choroidal neovascularization (12% when administered monthly, 7% when administered every other month and 3% in the control group) by Month 24. Patients receiving SYFOVRE should be monitored for signs of neovascular AMD. In case anti-Vascular Endothelial Growth Factor (anti-VEGF) is required, it should be given separately from SYFOVRE administration.


Intraocular Inflammation


In clinical trials, use of SYFOVRE was associated with episodes of intraocular inflammation including: vitritis, vitreal cells, iridocyclitis, uveitis, anterior chamber cells, iritis, and anterior chamber flare. After inflammation resolves, patients may resume treatment with SYFOVRE.


Increased Intraocular Pressure


Acute increase in IOP may occur within minutes of any intravitreal injection, including with SYFOVRE. Perfusion of the optic nerve head should be monitored following the injection and managed as needed.

ADVERSE REACTIONS


Most common adverse reactions (incidence ≥5%) are ocular discomfort, neovascular age-related macular degeneration, vitreous floaters, conjunctival hemorrhage.

Please see accompanying full Prescribing Information for more information.

U.S. Important Safety Information for EMPAVELI

BOXED WARNING: SERIOUS INFECTIONS CAUSED BY ENCAPSULATED BACTERIA


Meningococcal infections may occur in patients treated with EMPAVELI and may become rapidly life-threatening or fatal if not recognized and treated early. Use of EMPAVELI may predispose individuals to serious infections, especially those caused by encapsulated bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis types A, C, W, Y, and B, and Haemophilus influenzae type B.


Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against encapsulated bacteria.


Vaccinate patients at least 2 weeks prior to administering the first dose of EMPAVELI unless the risks of delaying therapy with EMPAVELI outweigh the risk of developing a serious infection.


Vaccination reduces, but does not eliminate, the risk of serious infections. Monitor patients for early signs of serious infections and evaluate immediately if infection is suspected.


EMPAVELI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Under the EMPAVELI REMS, prescribers must enroll in the program.

CONTRAINDICATIONS


Hypersensitivity to pegcetacoplan or to any of the excipients


Not currently vaccinated against certain encapsulated bacteria, unless the risks of delaying EMPAVELI treatment outweigh the risks of developing a bacterial infection with an encapsulated organism


Unresolved serious infection caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae

WARNINGS AND PRECAUTIONS

Serious Infections Caused by Encapsulated Bacteria

The use of EMPAVELI may predispose individuals to serious, life-threatening, or fatal infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis types A, C, W, Y, and B, and Haemophilus influenzae type B (Hib). To reduce the risk of infection, all patients must be vaccinated against these bacteria according to the most current ACIP recommendations for patients with altered immunocompetence associated with complement deficiencies. Revaccinate patients in accordance with ACIP recommendations considering the duration of therapy with EMPAVELI.

For patients without known history of vaccination, administer required vaccines at least 2 weeks prior to receiving the first dose of EMPAVELI. If immediate therapy with EMPAVELI is indicated, administer required vaccine as soon as possible and provide patients with 2 weeks of antibacterial drug prophylaxis.

Closely monitor patients for early signs and symptoms of serious infection and evaluate patients immediately if an infection is suspected. Promptly treat known infections. Serious infection may become rapidly life-threatening or fatal if not recognized and treated early. Consider discontinuation of EMPAVELI in patients who are undergoing treatment for serious infections.

EMPAVELI REMS

Because of the risk of serious infections, EMPAVELI is available only through a restricted program under a REMS. Under the EMPAVELI REMS, prescribers must enroll in the program and must counsel patients about the risk of serious infection, provide the patients with the REMS educational materials, and ensure patients are vaccinated against encapsulated bacteria. Enrollment and additional information are available by telephone: 1-888-343-7073 or at www.empavelirems.com.

Infusion-Related Reactions

Systemic hypersensitivity reactions (e.g., facial swelling, rash, urticaria) have occurred in patients treated with EMPAVELI. One patient (less than 1% in clinical studies) experienced a serious allergic reaction which resolved after treatment with antihistamines. If a severe hypersensitivity reaction (including anaphylaxis) occurs, discontinue EMPAVELI infusion immediately, institute appropriate treatment, per standard of care, and monitor until signs and symptoms are resolved.

Monitoring PNH Manifestations after Discontinuation of EMPAVELI

After discontinuing treatment with EMPAVELI, closely monitor for signs and symptoms of hemolysis, identified by elevated LDH levels along with sudden decrease in PNH clone size or hemoglobin, or reappearance of symptoms such as fatigue, hemoglobinuria, abdominal pain, dyspnea, major adverse vascular events (including thrombosis), dysphagia, or erectile dysfunction. Monitor any patient who discontinues EMPAVELI for at least 8 weeks to detect hemolysis and other reactions. If hemolysis, including elevated LDH, occurs after discontinuation of EMPAVELI, consider restarting treatment with EMPAVELI.

Interference with Laboratory Tests

There may be interference between silica reagents in coagulation panels and EMPAVELI that results in artificially prolonged activated partial thromboplastin time (aPTT); therefore, avoid the use of silica reagents in coagulation panels.

ADVERSE REACTIONS

Most common adverse reactions in patients with PNH (incidence ≥10%) were injection-site reactions, infections, diarrhea, abdominal pain, respiratory tract infection, pain in extremity, hypokalemia, fatigue, viral infection, cough, arthralgia, dizziness, headache, and rash.

USE IN SPECIFIC POPULATIONS

Females of Reproductive Potential

EMPAVELI may cause embryo-fetal harm when administered to pregnant women. Pregnancy testing is recommended for females of reproductive potential prior to treatment with EMPAVELI. Advise female patients of reproductive potential to use effective contraception during treatment with EMPAVELI and for 40 days after the last dose.

This approval is supported by interim analysis results from Part 1 of GSK’s Phase 3 RUBY trial. The dual-primary endpoints in Part 1 are investigator-assessed progression-free survival (PFS) and overall survival (OS). The statistical analysis plan included pre-specified analyses of PFS in the dMMR/MSI-H and intent-to-treat (ITT) populations and OS in the overall population. Part 1 of the RUBY trial continues to assess the dual-primary endpoint of OS in the ITT population.

"We are excited that JEMPERLI plus chemotherapy has been FDA-approved as the first new frontline treatment option in decades for patients with dMMR/MSI-H primary advanced or recurrent endometrial cancer," said Daniel Faga, interim president and chief executive officer of AnaptysBio. "We believe that royalties of JEMPERLI from this approval, as well as its potential in first-line ovarian cancer, in combination with Zejula and in second-line NSCLC, in combination with cobolimab, if GSK’s ongoing Phase 3 clinical trials lead to approvals, could over time contribute to our strong capital position as we focus on the development of our immune cell modulator pipeline, including our two checkpoint agonists in clinical-stage development, rosnilimab, a PD-1 agonist, and ANB032, a BTLA agonist."

JEMPERLI was discovered by AnaptysBio and licensed to TESARO, Inc., now a part of the GSK group of companies, under a Collaboration and Exclusive License Agreement signed in March 2014. GSK is responsible for the ongoing development and commercialization of JEMPERLI. AnaptysBio is entitled to receive milestones and tiered royalties of 8% for net sales of JEMPERLI below $1 billion and 12% up to 25% of net sales above $1 billion. In 2021, AnaptysBio monetized with Sagard Healthcare Royalty Partners certain commercial milestones and royalties for net sales of JEMPERLI below $1 billion up to a certain amount of receivables before such receivables revert back to AnaptysBio.

The sBLA supporting this new indication was reviewed under the FDA Oncology Center of Excellence Project Orbis Framework, which allowed for concurrent submission to and review by US and other international regulatory authorities. As part of Project Orbis, the application remains under review in Australia, Canada, Switzerland, Singapore and the United Kingdom. A marketing authorization application is also under review by the European Medicines Agency.

About RUBY

RUBY is a two-part global, randomized, double-blind, multicenter Phase 3 trial of patients with primary advanced or recurrent endometrial cancer. Part 1 is evaluating dostarlimab plus carboplatin-paclitaxel followed by dostarlimab versus carboplatin-paclitaxel plus placebo followed by placebo. Part 2 is evaluating dostarlimab plus carboplatin-paclitaxel followed by dostarlimab plus niraparib versus placebo plus carboplatin-paclitaxel followed by placebo.

The dual-primary endpoints in Part 1 are investigator-assessed PFS based on the Response Evaluation Criteria in Solid Tumors v1.1 and OS. The statistical analysis plan included pre-specified analyses of PFS in the dMMR/MSI-H and ITT populations and OS in the overall population. Pre-specified exploratory analyses of PFS in the mismatch repair proficient (MMRp)/microsatellite stable (MSS) population and OS in the dMMR/MSI-H populations were also performed. RUBY Part 1 included a broad population, including histologies often excluded from clinical trials and had approximately 10% of patients with carcinosarcoma and 20% with serous carcinoma. In Part 2, the primary endpoint is investigator-assessed PFS. Secondary endpoints in Part 1 and Part 2 include PFS per blinded independent central review, overall response rate, duration of response, disease control rate, patient-reported outcomes, and safety and tolerability.

About JEMPERLI (dostarlimab-gxly)

JEMPERLI is a programmed death receptor-1 (PD-1)-blocking antibody that binds to the PD-1 receptor and blocks its interaction with the PD-1 ligands PD-L1 and PD-L2. JEMPERLI is being investigated in registrational enabling studies, as monotherapy and as part of combination regimens, including in women with recurrent or primary advanced endometrial cancer, women with stage III or IV non-mucinous epithelial ovarian cancer, and in patients with other advanced solid tumors or metastatic cancers.

In the U.S., JEMPERLI is indicated for adult patients with mismatch repair-deficient (dMMR) recurrent or advanced endometrial cancer, as determined by an FDA-approved test, that has progressed on or following a prior platinum-containing regimen in any setting and are not candidates for curative surgery or radiation, and in combination with carboplatin and paclitaxel for the treatment of adult patients with primary advanced or recurrent endometrial cancer that is dMMR, as determined by an FDA-approved test, or microsatellite instability-high (MSI-H). The sBLA supporting this new indication received Breakthrough Therapy designation from the FDA. JEMPERLI is also indicated in the U.S. for patients with dMMR recurrent or advanced solid tumors, as determined by an FDA-approved test, that have progressed on or following prior treatment and who have no satisfactory alternative treatment options. The latter indication is approved in the U.S. under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication in solid tumors may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

The initiation of the second program was announced in January 2023 and the achievement of Technical Feasibility ensures the second research collaboration continues as planned, triggering a new milestone payment to Alligator.

In May 2023, the companies announced that Orion had selected bispecific lead antibodies in the companies’ first program and was exercising its option to develop these molecules further. Alligator is continuing to generate additional data in order for Orion to select the final development candidate.

"Achieving Technical Feasibility is an important milestone in our collaboration with Alligator to develop new immuno-oncology treatments," said Outi Vaarala, Senior Vice President, Innovative Medicines and R&D, Orion Corporation. "We are continuing to make highly encouraging progress towards identifying a final product candidate for clinical development "

"Our partnership with Orion continues to highlight the robust discovery and development capability of our technology platforms, in particular our ability to generate bispecific antibodies activated only in the presence of pre-specified proteins," said Søren Bregenholt, CEO of Alligator Bioscience. "It is also a great example of how strategic collaborations can increase the number of indications we can target within our pipeline, extend our patient reach, and maximize value for our company and shareholders."

Under the initial agreement signed in 2021, Alligator is employing its proprietary phage display libraries and RUBY bispecific antibody format to develop immuno-oncology drug candidates based on targets selected by Orion. Alligator is eligible for development, approval and sales milestone payments in addition to royalties if Orion continues developing and commercializing the resulting product candidates.

The world’s first BCMA/CD3 dual anti-Teclistamab received CDE breakthrough therapy

On July 31, 2023 the CDE official reported that Janssen’s universal T-cell redirecting BCMAxCD3 bispecific antibody teclistamab (Tecvayli) has been included in a breakthrough therapy for the treatment of relapsed or refractory multiple myeloma ( r/r MM) adult patients whose prior therapy included a proteasome inhibitor (PI), an immunomodulatory agent (IMiD), and an anti-CD38 monoclonal antibody (Press release, Johnson & Johnson, JUL 31, 2023, View Source [SID1234633516]).

Previously, in June 2021, the FDA also granted Breakthrough Drug Designation (BTD) to teclistamab for the treatment of r/r MM. On August 25, 2022, the European Union approved the conditional marketing of teclistamab, the first approval of teclistamab worldwide.

teclistamab is a bispecific antibody that targets B cell maturation antigen (BCMA) and T cell CD3 receptor. The expression level of BCMA was significantly increased on multiple myeloma cells, and CD3 was involved in activating T cells. teclistamab redirects CD3+ T cells to BCMA+ myeloma cells, resulting in their lysis and killing by CTL. Preclinical findings show that teclistamab kills myeloma cells from overly pretreated patients.

The EU approval is based on positive results from a multi-cohort, open-label Phase 1/2 clinical trial, MajesTEC-1. Results of the trial showed an overall response rate (ORR) of 63% in 165 patients with rrMM who received weekly subcutaneous injections of teclistamab after a median follow-up of 14.1 months.
