 Acalabrutinib, also known as ACP-196, is an orally available inhibitor of Bruton’s tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, ACP-196 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. BTK, a member of the src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it…

FDA permits marketing of device to treat diabetic foot ulcers

Release

Today, the U.S. Food and Drug Administration permitted the marketing of the Dermapace System, the first shock wave device intended to treat diabetic foot ulcers.

“Diabetes is the leading cause of lower limb amputations,” said Binita Ashar, M.D., director of the division of surgical devices in FDA’s Center for Devices and Radiological Health. “The FDA is dedicated to making technologies available that can help improve the quality of life for those with chronic diseases. Additional options for successfully treating and healing ulcer wounds may help prevent lower limb amputations.”

An estimated 30.3 million people in the United States have been diagnosed with diabetes, according to the Centers for Disease Control and Prevention. Diabetes damages blood vessels and nerves, particularly in the feet, and can lead to severe infections that are difficult to treat. About 25 percent of people with diabetes will experience a foot ulcer in their lifetime. Amputation is sometimes necessary when circulation is so poor that a foot ulcer fails to heal or when treatment fails to stop the spread of an infection.

The Dermapace System is intended to be used in the treatment of chronic, full-thickness diabetic foot ulcers with wound areas measuring no larger than 16 cm2(about the size of a soda can top) which extend through the epidermis, dermis, tendon, or capsule, but without bone exposure. The Dermapace System is an external (extracorporeal) shock wave system that uses pulses of energy, similar to sound waves, to mechanically stimulate the wound. The device is intended for adult patients (22 years and older), presenting with diabetic foot ulcers lasting for more than 30 days, and should be used along with standard diabetic ulcer care.

The FDA reviewed clinical data from two multi-center, randomized, double-blind studies with a total of 336 diabetic patients receiving either usual care, which includes wet-to-dry dressings or debridement (removal of damaged tissue) as needed, plus the Dermapace System shock wave therapy or usual care plus non-working (sham) shock wave therapy. Both patient groups included those with poorly controlled and well-controlled blood glucose levels.

The patients who had between one and seven treatments with the Dermapace System showed an increase in wound healing at 24 weeks with a 44 percent wound closure rate. Those patients treated with the sham shock wave therapy showed a 30 percent wound closure rate during the same time period.

The most common side effects observed were pain during application of the device, local bruising and numbness, migraines, nausea, fainting, wound infection, infection beyond the wound (cellulitis, osteomyelitis) and fever.

The Dermapace System was reviewed through the de novo premarket review pathway, a regulatory pathway for some low- to moderate-risk devices of a new type for which there is no legally marketed predicate device to which the device can claim substantial equivalence. This action also creates a new regulatory classification that would allow future devices to go through the FDA’s 510(k) process, whereby devices can demonstrate substantial equivalence to this predicate device.

The FDA permitted marketing of the Dermapace System to Sanuwave, Inc.

FDA updates the label of Tasigna to reflect that certain patients with a type of leukemia may be eligible to stop treatment after sustained response

Discontinuation in treatment marks a first in chronic myeloid leukemia 

The U.S. Food and Drug Administration today updated the product label for the cancer drug Tasigna (nilotonib) to include information for providers about how to discontinue the drug in certain patients. Tasigna, first approved by the FDA in 2007, is indicated for the treatment of patients with Philadelphia chromosome positive (Ph+) chronic myeloid leukemia (CML). With today’s updated dosing recommendations, patients with early (chronic) phase CML who have been taking Tasigna for three years or more, and whose leukemia has responded to treatment according to specific criteria as detected by a test that has received FDA marketing authorization, may be eligible to stop taking Tasigna. Continue reading

FDA clears stereotactic radiotherapy system for use in treating breast cancer

Release

Today, the U.S. Food and Drug Administration cleared a new noninvasive stereotactic radiotherapy system intended for use in treating cancer in breast tissue.

“With today’s clearance, patients will have access to a treatment option that provides greater accuracy in delivering radiation therapy to breast tumors while saving surrounding breast tissue,” said Robert Ochs, Ph.D., acting deputy director for radiological health in the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health.

Radiation therapy is an important treatment option for cancer patients. Approximately 60 percent of all cancer patients will be treated with some form of radiation therapy. During radiation therapy, tumor cells are killed when their DNA is damaged by the radiation being absorbed into them. While radiation therapy has the potential to kill tumor cells, it can also damage healthy tissue around the tumor.

The GammaPod system is intended for use in the noninvasive stereotactic delivery of a radiation dose to a portion (partial volume) of the breast in conjunction with breast conserving treatment. During the procedure, radiation is delivered to specific areas of the breast. The GammaPod has not been shown to be as effective as whole breast radiation therapy (WBRT) and is not intended to replace WBRT.

The GammaPod system is a dedicated stereotactic radiation therapy technology designed to treat breast cancer. GammaPod uses thousands of focused beams of radiation from 36 rotating radioactive Cobalt-60 sources in combination with a two-layer, vacuum-assisted cup that immobilizes the breast to achieve a more accurate delivery of radiation. The GammaPod design to immobilize the breast during treatment provides the benefit of minimizing the radiation dose to the surrounding healthy tissues in the breast, heart and lungs.

For today’s clearance, the FDA reviewed scientific evidence including a clinical study of 17 patients that tested the feasibility of accurately delivering the prescribed dose to the breast tumor while minimizing radiation to the healthy tissue. The clinical evidence supports delivering the prescribed dose to the breast tumor with minimal radiation-induced side effects such as skin redness or erythema.

The GammaPod system was reviewed through the premarket notification 510(k) pathway. A 510(k) is a premarket submission made by device manufacturers to the FDA to demonstrate that the new device is substantially equivalent to a legally marketed predicate device.

The FDA granted clearance of the GammaPod to Xcision Medical Systems, LLC.

Normal Operating Range (NOR) and Proven Acceptable Range (PAR)

Posted on

str1

In June of this year, the EMA issued a revision of their earlier Q&A document focused on NORs, PARs, and DSp.(2) First issued in draft form in 2015, this has been revised based on feedback and consultation with industry. The document focuses on five questions, which are summarized below along with a reflection on the answer provided and its implications.

1. What is a Normal Operating Range (NOR) and how should NORs be presented in the marketing authorisation dossier?

Answer: NOR is not an established ICH term. The NOR describes a region around the target operating conditions that contain common operational variability (variability that can’t always be controlled). A NOR can be established for several process parameters of the same process step, with the understanding that the NOR does not represent deliberate adaptation of the process, and that the NOR does not cover a parameter range that affects the quality of the process output. Otherwise, a PAR or a multivariate Design space should be established. The use of NORs alone is not intended to introduce flexibility in the conditions for manufacturing but to better quantify the actual uncontrollable operational variability of process parameters. NORs should therefore be presented in marketing authorisations as what is practically achievable.

Requests to provide details of NORs have become an increasingly prevalent request from reviewers, predominantly in Europe, the absence of such information being classified as a deficiency. It was noted that the term NOR seemed to have risen to prominence even though this it is not an ICH term. Interestingly the answer draws specific attention to this and concedes this is not a formal ICH term. The framing of this question is interesting and already indicates the EMA thinking by posing the question—how should NORs be presented? the subsequent answer makes very clear NORs should be presented. Is this an issue? Arguably not as many organizations have presented NORs within section S2.2 without challenge. But it makes abundantly clear that this is unlikely to be optional.
So what is an NOR? The document provides the following definition:
An NOR describes a region around the target operating conditions that contain common operational variability (variability that cannot always be precisely controlled to a single and specific value). This is consistent with the thinking of many and should allow the definition of a range which reflects equipment capability. For example, a range of 35 °C ± 5 C° may reasonably be considered an NOR given the variability of the temperature control and calibration systems.
Overall while effectively introducing a “new” term this is an established concept already widely used and thus this is not considered as a significant concern.

What Is a Proven Acceptable Range (PAR) and How Should PARs Be Justified and Presented in the Marketing Authorization Dossier?


Again a specific definition is provided:
The PAR is defined as a characterized range of a process parameter for which operation within this range, while keeping other parameters within set points or NORs, will result in producing a material meeting relevant quality criteria (ICH Q8 R2).(1)
A key phrase within this seems to be the statement that other parameters must be kept constant. Is this ever the reality, and what is constant? Later in the document in the answer pertaining to DSp, there is effective recognition that some form of interrelationship will generally exist. What is perhaps more important is establishing the criticality of this relationship not that one simply exists. Later within the answer it is also stated that where an interaction exists between different parameters, the parameters should be included in a Design Space. One might be forgiven for believing that this may penalize the more diligent applicant who seeks to properly study possible interactions. Missing at present is clarity around what happens if you explore multiple parameters and find no interactions or more likely no “significant” interactions. In such circumstances where the interactions have no impact, it should be possible to justify multiple ranges (or at least a range wider than the NOR).
There is also a need to understand more about when an interaction is significant. If there are no interactions across the ranges proposed and no impact on drug substance quality is demonstrated with multivariate experiments, then surely we do not need a design space—it adds no value and makes no sense.
