allow for earlier approval of drugs that treat serious conditions and that fill an unmet medical need based on a surrogate endpoint. In addition, we are initiating a multi-center Early Access Program, or EAP, in the United States for pediatric patients to provide access to treatment with Oxbryta prior to potential market authorization for children ages 4 to 11 who, in the judgment of their treating physician, have an urgent need for treatment for their SCD, have no comparable or satisfactory treatment options and are unable to participate in our clinical trials.
In June 2020, we announced plans to submit by
mid-2021
a Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMA, seeking full marketing authorization of Oxbryta to treat hemolytic anemia (which is low hemoglobin due to red blood cell destruction) in SCD patients ages 12 years and older. The planned MAA will include data from our Phase 3 HOPE Study and our Phase 2 HOPE-KIDS 1 Study, both of which enrolled patients at clinical sites in Europe. In addition, we announced our intention to initiate an EAP in Europe for patients and physicians who may need access to Oxbryta prior to potential marketing authorization.
In September 2020, we announced our entry into an exclusive agreement with Biopharma-Middle East and Africa to distribute Oxbryta in Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, collectively known as the Gulf Cooperation Council, or GCC, region. In the GCC region, the U.S. approval of Oxbryta can be referenced to allow for access to the medicine while health authorities conduct their reviews.
Beyond Oxbryta, we are also engaged in other research and development activities, all of which are currently in earlier development stages, including working on new targets to develop the next generation of treatments for SCD. As part of our efforts to build our pipeline, we regularly evaluate opportunities to
in-license,
acquire or invest in new business, technology or assets or engage in related discussions with other business entities.
In August 2018, we entered into the License Agreement, or Roche Agreement, with F.
Hoffmann-La
Roche Ltd. and
Hoffmann-La
Roche Inc. (together, “Roche”) pursuant to which Roche granted us an exclusive and sublicensable worldwide license under certain patent rights and
know-how
to develop and commercialize inclacumab, a
p-selectin
inhibitor in development to address pain crises associated with the disease, including any modified compounds targeting
p-selectin
and derived from inclacumab, for all indications and uses, except diagnostic use. Roche retained a
non-exclusive,
worldwide, perpetual, royalty-free license to inclacumab solely for any diagnostic use. We are developing inclacumab as a treatment for vaso-occlusive crises, or VOCs, in patients with SCD, and we expect to be able to leverage the safety data from Roche’s prior clinical studies, which were not in patients with SCD, as we proceed with our development of inclacumab. We expect to initiate a pivotal clinical study by the end of the first half of 2021.
In December 2019, we entered into the License and Collaboration Agreement, or Syros Agreement, with Syros Pharmaceuticals, Inc., or Syros, to discover, develop and commercialize novel therapies for SCD and beta thalassemia. Under the agreement, Syros will use its leading gene control platform to identify therapeutic targets and discover drugs that potentially induce fetal hemoglobin, and we have an option to obtain an exclusive worldwide license to develop, manufacture and commercialize any compounds or products resulting from the collaboration, subject to Syros’ option to
co-promote
the first product in the United States.
The outbreak of the novel coronavirus,
which causes coronavirus disease 2019
(COVID-19),
has evolved into a global pandemic that has impacted our business, including our commercialization of Oxbryta and our research and development activities. For example, we have implemented a temporary work from home policy, temporarily suspended our field team from most
in-person
interactions, including visits to physician offices, clinics and hospitals as well as
in-person
meetings with payors, and temporarily delayed or paused certain research and development activities, including screening and enrollment in all
GBT-sponsored
studies, including our Phase 2a HOPE-KIDS 1 Study, our Phase 3 HOPE-KIDS 2 Study and our dose optimization study that is intended to assess doses of Oxbryta of up to 3,000 mg per day. As we continue to monitor and work toward resumption of all trial activities, we are continuing with administrative trial-start up activities (such as contracting and IRB/EC approvals). Notably, the
COVID-19
pandemic has not significantly impacted our supply of Oxbryta. We continue to believe we have an adequate supply of Oxbryta to sustain estimated patient need through the remainder of this year and into late 2021, and we are continuing to produce Oxbryta tablets. In addition, we are continuing to engage with healthcare professionals and payors through increased use of digital and internet-based education and outreach. We have seen a significant decrease in weekly new patient prescriptions for Oxbryta from a peak in early March, and we expect the rate of new patient prescriptions to remain lower, possibly through the fourth quarter of 2020, and potentially longer depending on the course of the pandemic. While we intend to resume normal operations as soon as practicable, we do not know for certain the extent or duration of these and other disruptions or the long-term impact on our business.
We own or jointly own and have exclusively licensed rights to Oxbryta and our product candidates in the United States, Europe and other major markets. We are the sole owner of issued U.S. patents covering Oxbryta, including its composition of matter, methods of use, formulations and polymorphs of Oxbryta. These issued U.S. patents covering Oxbryta will expire between 2032 and 2037, absent any applicable patent term extensions. We own or
co-own
additional pending patent applications in the United States and multiple foreign countries relating to Oxbryta.
