Drug granted orphan designation for DLBCL
The US Food and Drug Administration (FDA) has granted orphan designation to the oncology drug candidate PNT2258 for the treatment of diffuse large B-cell lymphoma (DLBCL).
The FDA grants orphan designation to drugs intended to treat conditions affecting fewer than 200,000 patients in the US.
The designation provides the drug’s sponsor with various development incentives, including opportunities to apply for research-related tax credits and grant funding, assistance in designing clinical trials, and 7 years of US market exclusivity if the drug is approved.
About PNT2258
PNT2258 is designed to target cancers that overexpress BCL2, and BCL2 overexpression is thought to be a key driver of DLBCL.
PNT2258 consists of a single-stranded, 24-base DNAi oligonucleotide known as PNT100 that is encapsulated in lipid nanoparticles (LNPs).
The DNAi technology platform is based on a discovery that single-stranded DNA oligonucleotides can interact with genomic DNA to interfere with oncogenes. PNT100 DNAi is designed to target a genetic regulatory region associated with BCL2.
The LNPs are designed to provide enhanced serum stability and optimized pharmacokinetic properties to facilitate broad systemic distribution after intravenous infusion. Within the acidic environment found in tumors, the LNPs become positively charged and therefore more amenable to cellular uptake and cytoplasmic release of their payloads.
Trials of PNT2258
PNT2258 is being developed by ProNAi Therapeutics, Inc. The company has completed 2 trials of PNT2258 to date—a phase 1 trial of patients with solid tumors and a phase 2 trial of patients with non-Hodgkin lymphoma.
The phase 1 trial enrolled 22 patients with relapsed or refractory solid tumor malignancies. Results were published in Cancer Chemotherapy and Pharmacology in February 2014.
PNT2258 was deemed well-tolerated in this trial. There was no evidence of a systemic immune response to the LNPs or PNT100. There were no significant changes in immune-stimulatory cytokines or clinical signs of anaphylaxis following PNT2258 administration.
The phase 2 trial enrolled 13 patients with relapsed or refractory non-Hodgkin lymphoma. Results were presented at ASH 2014 (abstract 1716).
Six patients responded to PNT2258—4 with complete responses and 2 with partial responses. Five patients had stable disease, and 2 progressed. All 4 of the DLBCL patients in this trial responded—3 with complete responses and 1 with a partial response.
Adverse events reported in this trial include nausea (n=11), pain (n=9), chills (n=7), diarrhea (n=7), vomiting (n=7), fatigue (n=6), fever (n=6), headache (n=6), dyspnea (n=5), generalized aching (n=4), anorexia (n=4), back pain (n=4), sensory neuropathy (n=4), hypophosphatemia (n=4), anemia (n=3), hypokalemia (n=3), hyperuricemia (n=2), neutropenia (n=2), thrombocytopenia (n=4), and elevated AST/ALT (n=1).
ProNAi Therapeutics is now enrolling patients in “Wolverine,” a phase 2 trial evaluating PNT2258 in patients with relapsed or refractory DLBCL, and in “Brighton,” a phase 2 trial evaluating PNT2258 for the treatment of Richter’s transformation.

Gilead Sciences, Inc.
The European Medicines Agency (EMA) is reviewing the safety of idelalisib (Zydelig), a drug approved to treat chronic lymphocytic leukemia (CLL) and follicular lymphoma in the European Union (EU).
The European Commission (EC) requested the review because of serious adverse events (AEs), including deaths, reported in 3 clinical trials investigating idelalisib in combination with other drugs.
The AEs were mostly infection-related.
The EMA is reviewing data from these studies to assess whether the findings have any consequences for the authorized uses of idelalisib.
In the meantime, the EMA advises that patients starting or already on treatment with idelalisib be carefully monitored for signs of infections. If the drug is well tolerated, treatment should not be stopped.
The EMA is considering whether any other immediate measures are necessary during the review period. The agency said it will communicate further and keep doctors and patients informed as appropriate.
About idelalisib
In the EU, idelalisib is approved for use in combination with rituximab to treat adults with CLL who have received at least 1 prior therapy or as first-line treatment in the presence of 17p deletion or TP53 mutation in CLL patients unsuitable for chemo-immunotherapy.
Idelalisib is also approved as monotherapy for adults with follicular lymphoma that is refractory to 2 prior lines of treatment.
About the trials
The trials in which patients have experienced serious AEs involve patients with CLL and indolent non-Hodgkin lymphoma (NHL).
In one trial (NCT01732926), researchers are evaluating idelalisib in combination with bendamustine and rituximab for previously treated indolent NHL.
In another (NCT01732913), researchers are testing idelalisib in combination with rituximab for previously treated indolent NHL.
And in the third (NCT01980888), researchers are evaluating idelalisib in combination with bendamustine and rituximab in patients with previously untreated CLL.
The EMA noted that these studies are investigating combinations of drugs that are currently not approved in the EU and include patients with disease characteristics different from those covered by the approved indications for idelalisib.
About the review
The EMA has begun the review of idelalisib at the request of the EC, under Article 20 of Directive 2001/83/EC.
The review is being carried out by the EMA’s Pharmacovigilance Risk Assessment Committee, the committee responsible for the evaluation of safety issues for human medicines, which will make a set of recommendations.
Those recommendations will then be forwarded to the Committee for Medicinal Products for Human Use, which is responsible for questions concerning medicines for human use and will adopt a final opinion on the safety of idelalisib.
The final stage of the review procedure is the EC’s adoption of a legally binding decision that is applicable in all EU member states.

Program can predict drug side effects
Photo by Darren Baker
Scientists say they have developed a computer program that can predict whether or not a given pharmaceutical agent will produce certain side effects.
The software takes an “ensemble approach” to assessing the chemical structure of a drug molecule and can determine whether key substructures are present in the molecule that are known to give rise to side effects in other drugs.
Md Jamiul Jahid and Jianhua Ruan, PhD, both of the University of Texas at San Antonio, developed the computer program and described it in the International Journal of Computational Biology and Drug Design.
The pair tested the software’s ability to predict 1385 side effects associated with 888 marketed drugs and found that the program outperformed earlier software.
The team also used their new software to test 2883 uncharacterized compounds in the DrugBank database. The program proved capable of predicting a wide variety of side effects, including some effects that were missed by other screening methods.
The scientists believe their software could be used to alert regulatory authorities and healthcare workers as to what side effects might occur when a new drug enters late-stage clinical trials and is ultimately brought to market.
But the program may have an additional benefit as well. By identifying substructures that are associated with particular side effects, the software could be used to help medicinal chemists understand the underlying mechanism by which a side effect arises.
The chemists could then eliminate the offending substructures from drug molecules in the future, thereby reducing the number of drugs that go through the research and development pipeline and then fail in clinical trials due to severe side effects.

FDA lifts partial clinical hold on pidilizumab
The US Food and Drug Administration (FDA) has lifted the partial clinical hold on the investigational new drug (IND) application for pidilizumab (MDV9300) in hematologic malignancies.
This means the phase 2 trial of pidilizumab in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), as well as other studies that cross-reference the IND for the drug, may now proceed.
The partial clinical hold on pidilizumab was not related to any safety concerns.
The FDA placed the hold because the company developing pidilizumab, Medivation Inc., determined that the drug is not an inhibitor of PD-1, as researchers previously thought.
The phase 2 trial of pidilizumab in DLBCL was launched in late 2015 but had not enrolled any patients before the FDA placed the partial clinical hold.
Patients who were receiving pidilizumab through investigator-sponsored trials have continued to receive treatment despite the hold, and those investigators have been told to update their protocols and informed consent documents to reflect that pidilizumab is not an anti-PD-1 antibody.
Medivation has likewise revised the investigator brochure, protocols, and informed consent documents related to the phase 2 trial of DLBCL patients.
The company said it is still trying to determine pidilizumab’s mechanism of action.
“We are delighted that the FDA has lifted the partial clinical hold and that we may proceed with our potentially pivotal trial in this area of high unmet medical need,” said David Hung, MD, founder, president, and chief executive officer of Medivation.
“As we move forward, we also are working to determine the compound’s exact binding mechanism which, we believe, modulates the body’s innate immune response and differentiates it from the heavily crowded immuno-oncology space that targets the adaptive side of immunity.”
Medivation said it intends to submit an amendment to the Chemistry, Manufacturing, and Controls section of the IND for pidilizumab to provide for larger manufacturing lot sizes to better support the current and planned clinical activities for the drug.
The company also said it plans to resume the phase 2 trial of pidilizumab in DLBLCL in the second half of this year.
The trial is expected to enroll approximately 180 patients who had an incomplete response to salvage therapy or autologous stem cell transplant for relapsed or refractory CD20+ DLBCL, transformed indolent lymphoma, or primary mediastinal B-cell lymphoma.
The patients will be assessed in 2 parallel cohorts of approximately 90 patients each. One cohort will enroll patients who have received an autologous stem cell transplant, and the other will enroll patients who have received salvage chemotherapy but are ineligible for transplant.
Pidilizumab will be given at a dose of 200 mg by intravenous infusion. The primary endpoint of the trial is best overall response rate.

EMA initiative aims to accelerate drug development

The European Medicines Agency (EMA) has launched PRIME (PRIority MEdicines), an initiative intended to accelerate the development of drugs that target unmet medical needs.
These “priority medicines” may offer a major therapeutic advantage over existing treatments or benefit patients who currently have no treatment options in the European Union (EU).
Through PRIME, the EMA will offer early support to drug developers to optimize the generation of robust data on a treatment’s benefits and risks and enable accelerated assessment of an application for marketing authorization.
By engaging with developers early, the EMA aims to strengthen the design of clinical trials to facilitate the generation of high quality data to support an application for marketing authorization.
PRIME builds on the existing regulatory framework and available tools such as scientific advice and accelerated assessment.
To be accepted for PRIME, a treatment has to show the potential to benefit patients with unmet medical needs based on early clinical data.
Once a candidate medicine has been selected for PRIME, the EMA:
- Appoints a rapporteur from the Committee for Medicinal Products for Human Use (CHMP), or from the Committee on Advanced Therapies (CAT) in the case of an advanced therapy, to provide continuous support and help to build knowledge before a company submits an application for marketing authorization
- Organizes a kick-off meeting with the CHMP/CAT rapporteur and a multidisciplinary group of experts from relevant EMA scientific committees and working parties, and provides guidance on the overall development plan and regulatory strategy
- Assigns a dedicated EMA contact point
- Provides scientific advice at key development milestones, involving additional stakeholders such as health technology assessment bodies to facilitate quicker access to the new drug
- Confirms potential for accelerated assessment when an application for marketing authorization is submitted.
PRIME is open to all drug companies on the basis of preliminary clinical evidence. However, micro-, small- and medium-sized enterprises and applicants from the academic sector can apply earlier on the basis of compelling non-clinical data and tolerability data from initial clinical trials. They may also request fee waivers for scientific advice.
The EMA has released guidance documents on PRIME as well as a comprehensive overview of the EU early access regulatory tools—ie, accelerated assessment, conditional marketing authorization, and compassionate use.
The agency has also published revised guidelines on the implementation of accelerated assessment and conditional marketing authorization. These tools are reserved for treatments addressing major public health needs, and the revised guidelines provide more detailed information based on past experience.
Although PRIME is specifically designed to promote accelerated assessment, the EMA said the initiative will also help drug developers make the best use of other EU early access tools and initiatives, which can be combined whenever a drug fulfills the respective criteria.
PRIME was developed in consultation with the EMA’s scientific committees, the European Commission and its expert group on Safe and Timely Access to Medicines for Patients, as well as the European medicines regulatory network.
The main principles of PRIME were released for a 2-month public consultation in 2015, and the comments received were taken into account in the final version.

To be accepted for PRIME, a treatment has to show the potential to benefit patients with unmet medical needs based on early clinical data.
Once a candidate medicine has been selected for PRIME, the EMA:
- Appoints a rapporteur from the Committee for Medicinal Products for Human Use (CHMP), or from the Committee on Advanced Therapies (CAT) in the case of an advanced therapy, to provide continuous support and help to build knowledge before a company submits an application for marketing authorization
- Organizes a kick-off meeting with the CHMP/CAT rapporteur and a multidisciplinary group of experts from relevant EMA scientific committees and working parties, and provides guidance on the overall development plan and regulatory strategy
- Assigns a dedicated EMA contact point
- Provides scientific advice at key development milestones, involving additional stakeholders such as health technology assessment bodies to facilitate quicker access to the new drug
- Confirms potential for accelerated assessment when an application for marketing authorization is submitted.
PRIME is open to all drug companies on the basis of preliminary clinical evidence. However, micro-, small- and medium-sized enterprises and applicants from the academic sector can apply earlier on the basis of compelling non-clinical data and tolerability data from initial clinical trials. They may also request fee waivers for scientific advice.
The EMA has released guidance documents on PRIME as well as a comprehensive overview of the EU early access regulatory tools—ie, accelerated assessment, conditional marketing authorization, and compassionate use.
The agency has also published revised guidelines on the implementation of accelerated assessment and conditional marketing authorization. These tools are reserved for treatments addressing major public health needs, and the revised guidelines provide more detailed information based on past experience.
Although PRIME is specifically designed to promote accelerated assessment, the EMA said the initiative will also help drug developers make the best use of other EU early access tools and initiatives, which can be combined whenever a drug fulfills the respective criteria.
PRIME was developed in consultation with the EMA’s scientific committees, the European Commission and its expert group on Safe and Timely Access to Medicines for Patients, as well as the European medicines regulatory network.
The main principles of PRIME were released for a 2-month public consultation in 2015, and the comments received were taken into account in the final version.

The European Medicines Agency (EMA) has launched PRIME (PRIority MEdicines), an initiative intended to accelerate the development of drugs that target unmet medical needs.
These “priority medicines” may offer a major therapeutic advantage over existing treatments or benefit patients who currently have no treatment options in the European Union (EU).
Through PRIME, the EMA will offer early support to drug developers to optimize the generation of robust data on a treatment’s benefits and risks and enable accelerated assessment of an application for marketing authorization.

FDA approves long-acting hemophilia B therapy
The US Food and Drug Administration (FDA) has approved Idelvion (Coagulation Factor IX [Recombinant], Albumin Fusion Protein) for the treatment of hemophilia B.
The product—a fusion protein linking recombinant coagulation factor IX with recombinant albumin—is intended for use in children and adults for routine prophylaxis to prevent or reduce the frequency of bleeding episodes, for on-demand control and prevention of bleeding episodes, and for the perioperative management of bleeding.
Appropriate patients age 12 and older can go up to 14 days between Idelvion infusions. This dosing interval has been achieved while maintaining high levels of factor IX activity—above 5% over 14 days at 75 IU/kg.
Idelvion is the first FDA-approved recombinant factor IX therapy that can extend the dosing interval up to 14 days.
Idelvion is expected to be available in the US later this month. The product is being developed by CSL Behring. For more details on the drug, see the full prescribing information.
Phase 3 trial
The FDA approved Idelvion based on results of the PROLONG-9FP clinical development program. PROLONG-9FP includes phase 1, 2, and 3 studies evaluating the safety and efficacy of Idelvion in adults and children (ages 1 to 61) with hemophilia B.
Data from the phase 3 study were recently published in Blood. This study included 63 previously treated male patients with severe hemophilia B. They had a mean age of 33 (range, 12 to 61).
The patients were divided into 2 groups. Group 1 (n=40) received routine prophylaxis with Idelvion once every 7 days for 26 weeks, followed by a 7-, 10- or 14-day prophylaxis regimen for a mean of 50, 38, or 51 weeks, respectively.
Group 2 received on-demand treatment with Idelvion for bleeding episodes for 26 weeks (n=23) and then switched to a 7-day prophylaxis regimen for a mean of 45 weeks (n=19).
The median annualized bleeding rate (ABR) was 2.0 in the prophylaxis arm (group 1) and 23.5 in the on-demand treatment arm (group 2). The median spontaneous ABRs were 0.0 and 17.0, respectively.
For patients in group 2, there was a significant reduction in median ABRs when patients switched from on-demand treatment to prophylaxis—19.22 and 1.58, respectively (P<0.0001). And there was a significant reduction in median spontaneous ABRs—15.43 and 0.00, respectively (P<0.0001).
Overall, 98.6% of bleeding episodes were treated successfully, including 93.6% that were treated with a single injection of Idelvion.
None of the patients developed inhibitors or experienced thromboembolic events, anaphylaxis, or life-threatening adverse events (AEs).
There were 347 treatment-emergent AEs reported in 54 (85.7%) patients. The most common were nasopharyngitis (25.4%), headache (23.8%), arthralgia (4.3%), and influenza (11.1%).
Eleven mild/moderate AEs in 5 patients (7.9%) were considered possibly related to Idelvion. Two patients discontinued treatment due to AEs—1 with hypersensitivity and 1 with headache.

The US Food and Drug Administration (FDA) has approved the BTK inhibitor ibrutinib (Imbruvica) as a first-line treatment for patients with chronic lymphocytic leukemia (CLL).
This means ibrutinib is now FDA-approved to treat CLL patients regardless of their treatment history, including patients with 17p deletion.
Ibrutinib is also FDA-approved to treat Waldenström’s macroglobulinemia, and the drug was granted accelerated approval to treat patients with mantle cell lymphoma who have received at least 1 prior therapy.
Ibrutinib is jointly developed and commercialized by Pharmacyclics LLC, an AbbVie company, and Janssen Biotech, Inc. For more details on the drug, see the full prescribing information, available at imbruvica.com.
RESONATE-2 trial
The latest FDA approval for ibrutinib is based on results from the phase 3 RESONATE-2 trial (PCYC-1115), which were presented at the 2015 ASH Annual Meeting and simultaneously published in NEJM.
RESONATE-2 enrolled 269 treatment-naïve patients with CLL or small lymphocytic lymphoma who were 65 or older.
Patients were randomized to receive ibrutinib (n=136) at 420 mg once a day until progression or unacceptable toxicity, or chlorambucil (n=133) on days 1 and 15 of each 28-day cycle for up to 12 cycles. The starting dose for chlorambucil in cycle 1 was 0.5 mg/kg and was increased based on tolerability in cycle 2 by increments of 0.1 mg/kg to a maximum of 0.8 mg/kg.
The primary endpoint of the study was progression-free survival (PFS), as assessed by an independent review committee (IRC) according to the International Workshop on Chronic Lymphocytic Leukemia (iWCLL) 2008 criteria, with modification for treatment-related lymphocytosis.
Key secondary endpoints included overall response rate (based on the same iWCLL criteria), overall survival (OS), and safety.
Ibrutinib significantly prolonged PFS, as determined by the IRC, reducing the risk of progression or death by 84% compared to chlorambucil. The hazard ratio was 0.16 (P<0.001). The median PFS was not reached in the ibrutinib arm but was 18.9 months for the chlorambucil arm.
Ibrutinib significantly prolonged OS as well, although the median OS was not reached in either treatment arm. The OS rate at 24 months was 98% with ibrutinib and 85% with chlorambucil. The relative risk of death with ibrutinib was 84% lower than that with chlorambucil. The hazard ratio was 0.16 (P=0.001).
Ibrutinib was associated with a significantly higher IRC-assessed overall response rate compared to chlorambucil—82% and 35%, respectively (P<0.0001). Five patients (4%) in the ibrutinib arm achieved a complete response, as did 2 patients (2%) in the chlorambucil arm.
The median duration of treatment was 17.4 months in the ibrutinib arm and 7.1 months in the chlorambucil arm.
The most common adverse events of any grade—in the ibrutinib and chlorambucil arms, respectively—were diarrhea (42% and 17%), fatigue (30% and 38%), cough (22% and 15%), nausea (22% and 39%), peripheral edema (19% and 9%), dry eye (17% and 5%), arthralgia (16% and 7%), neutropenia (16% and 23%), and vomiting (13% and 20%).
Adverse events of grade 3 or higher—in the ibrutinib and chlorambucil arms, respectively—were neutropenia (10% and 18%), anemia (6% and 8%), hypertension (4% and 0%), pneumonia (4% and 2%), diarrhea (4% and 0%), maculopapular rash (3% and 2%), decreased platelet count (3% and 1%), abdominal pain (3% and 1%), hyponatremia (3% and 0%), thrombocytopenia (2% and 6%), febrile neutropenia (2% and 2%), upper respiratory tract infection (2% and 2%), pleural effusion (2% and 1%), cellulitis (2% and 0%), fatigue (1% and 5%), syncope (1% and 2%), and hemolytic anemia (0% and 2%).

Gene therapy granted orphan designation for hemophilia A
Image courtesy of NHLBI
The US Food and Drug Administration (FDA) has granted orphan designation to BMN 270, an investigational gene therapy, for the treatment of patients with hemophilia A.
BMN 270 is an adeno-associated virus-factor VIII (FVIII) vector designed to restore FVIII plasma concentrations in these patients.
The FDA grants orphan designation to drugs that are intended to treat diseases or conditions affecting fewer than 200,000 patients in the US.
The designation provides the drug’s sponsor with various development incentives, including opportunities to apply for research-related tax credits and grant funding, assistance in designing clinical trials, and 7 years of US market exclusivity if the drug is approved.
BMN 270 is under development by BioMarin Pharmaceutical Inc.
BioMarin is conducting a phase 1/2 study to evaluate the safety and efficacy of BMN 270 in up to 12 patients with severe hemophilia A.
Researchers are assessing the safety of a single infusion of BMN 270 and the change in FVIII expression level from baseline to 16 weeks after infusion.
The group is also assessing the impact of BMN 270 on the frequency of FVIII replacement therapy, the number of bleeding episodes requiring treatment, and any potential immune responses.
Patients will be monitored for safety and durability of effect for 5 years. BioMarin plans to provide an update on this trial in April.

EC approves drug for iron-deficiency anemia in IBD
The European Commission (EC) has granted marketing authorization for ferric maltol (Feraccru) to treat iron-deficiency anemia in adults with inflammatory bowel disease (IBD).
The product can now be marketed for this indication in the 28 member countries of the European Union, as well as Iceland, Liechtenstein, and Norway.
The company developing the drug, Shield Therapeutics, said it will begin a roll-out of commercialization in the coming months.
Feraccru contains iron in a stable ferric state as a complex with a trimaltol ligand—ferric maltol. It is formulated as 30 mg of ferric iron in a hard gelatin capsule.
The complex is designed to provide iron for uptake across the intestinal wall and transfer to the iron transport and storage proteins—transferrin and ferritin, respectively. Feraccru dissociates on uptake from the gastrointestinal tract, and ferric maltol itself does not appear to enter the systemic circulation.
Phase 3 trials
The EC’s approval of ferric maltol is based on results of 2 phase 3 studies—AEGIS 1 and AEGIS 2. The results of these studies were published in Inflammatory Bowel Diseases in March 2015.
Together, the trials included 128 adult patients with IBD (ulcerative colitis and Crohn’s disease), iron-deficiency anemia, and recorded intolerance of ferrous sulphate. They were randomized to receive either 30 mg of ferric maltol twice a day or a matched placebo capsule for 12 weeks.
The primary efficacy endpoint was the change in hemoglobin (Hb) levels from baseline to week 12. The mean improvement in Hb in the ferric maltol group compared to the placebo group was 2.25 g/dL (P<0.0001).
The absolute mean Hb concentration improved from 11.00 g/dL at baseline to 13.20 g/dL at week 12 in the ferric maltol group. In the placebo group, the mean Hb values were similar at baseline and week 12—11.10 g/dL and 11.20 g/dL, respectively.
The incidence of treatment-emergent adverse events (AEs) was 58% in the ferric maltol group and 72% in the placebo group. However, not all of these events were considered treatment-related.
AEs that were considered treatment-related occurred in 25% of ferric maltol-treated patients and 11.7% of placebo-treated patients. The most common treatment-related AEs in the ferric maltol group were abdominal pain, constipation, and flatulence—each occurring in 6.7% of patients.
“The phase 3 clinical studies clearly demonstrated Feraccru’s effectiveness,” said Andreas Stallmach, MD, of University Clinic Jena in Germany.
“[T]his pan-European marketing authorization gives treating physicians like myself the opportunity to fulfill an important and currently unmet need for patients who are unable to tolerate other oral products, as Feraccru could provide an oral alternative to intravenous iron infusion.’’
The European Commission (EC) has granted marketing authorization for ferric maltol (Feraccru) to treat iron-deficiency anemia in adults with inflammatory bowel disease (IBD).
The product can now be marketed for this indication in the 28 member countries of the European Union, as well as Iceland, Liechtenstein, and Norway.
The company developing the drug, Shield Therapeutics, said it will begin a roll-out of commercialization in the coming months.
Feraccru contains iron in a stable ferric state as a complex with a trimaltol ligand—ferric maltol. It is formulated as 30 mg of ferric iron in a hard gelatin capsule.
The complex is designed to provide iron for uptake across the intestinal wall and transfer to the iron transport and storage proteins—transferrin and ferritin, respectively. Feraccru dissociates on uptake from the gastrointestinal tract, and ferric maltol itself does not appear to enter the systemic circulation.

Drug granted orphan designation for hemolytic anemia
The European Commission (EC) has granted orphan drug designation for TNT009 to treat autoimmune hemolytic anemia, including cold agglutinin disease.
TNT009 is a monoclonal antibody that selectively inhibits the classical complement pathway by targeting C1s, a serine protease within the C1-complex in the complement pathway.
The drug thereby prevents downstream disease processes involving phagocytosis, inflammation, and cell lysis.
TNT009 is being developed by True North Therapeutics.
The drug is currently in development for the treatment of autoimmune hemolytic anemia, which is characterized by the premature destruction of healthy red blood cells by autoantibodies.
In cold agglutinin disease, this destruction of red blood cells results in anemia, fatigue, and potentially fatal thrombosis.
TNT009 is also being evaluated in patients with bullous pemphigoid and end-stage renal disease.
Top-line results from a phase 1b trial of TNT009 are expected in mid-2016.
About orphan designation
The EC grants orphan designation to products intended to treat, prevent, or diagnose a life-threatening condition affecting up to 5 in 10,000 people in the European Union. The product must provide significant benefit to those affected by the condition.
Orphan drug designation from the EC provides companies with certain development incentives, including protocol assistance, a type of scientific advice specific for orphan drugs, and 10 years of market exclusivity once the drug is on the market.
