The draft II. Background The NRC is requesting public comment on the draft licensing guidance entitled ‘‘Yttrium-90 Microsphere Brachytherapy Sources and Devices TheraSphere® and SIRSpheres® Licensing Guidance.’’ This draft would be revision 10 to this licensing guidance. The licensing guidance provides medical use applicants with an acceptable means of satisfying the requirements for a license for the use of TheraSphere® and SIRSpheres® and is not intended to be the only means of satisfying the requirements for a license. The licensing guidance provides the NRC with a set of standard criteria for evaluating a license application, although an applicant may submit alternative information and commitments for review by the NRC staff to make a licensing determination unless the information is specifically ethrower on DSK3G9T082PROD with NOTICES I. Obtaining Information and Submitting Comments VerDate Sep<11>2014 17:29 Nov 06, 2017 Jkt 244001 PO 00000 Frm 00060 Fmt 4703 Sfmt 4703 required by regulation. This guidance will also be available for voluntary use by Agreement States. The licensing guidance for Y–90 microsphere brachytherapy was initially published in October 2002 and subsequently revised in 2004, 2007, 2008, 2011, 2012, and 2016. Following years of using the current licensing guidance, the NRC staff, stakeholders, and the Advisory Committee on the Medical Uses of Isotopes (ACMUI) have identified numerous issues that need to be addressed. A working group comprised of Agreement State representatives and NRC staff was formed to address identified issues. The document has been revised to significantly update the criteria for training and experience, medical event reporting, inventory requirement specifications, and waste disposal issues. The revised guidance document also provides new information regarding cremation and autopsy. As described in the draft licensing guidance, the NRC is recommending removal of the alternate, manufacturer provided clinical training pathway to complete the training and experience criteria listed in Section B of the training and experience section of the licensing guidance. During an ACMUI meeting on October 7, 2016 (ML16357A688), the ACMUI recommended that the NRC leave this alternate pathway in the Y–90 microsphere licensing guidance to allow access to Y–90 microsphere brachytherapy in areas where there may not already be approved AUs to supervise new physicians. However, after licensing Y–90 microspheres under 10 CFR 35.1000 for over 10 years, there should be substantial facilities and AUs available to offer training for Y–90 microspheres, similar to other therapeutic modalities, and therefore this pathway should be removed to bring Y–90 microsphere brachytherapy training and experience (T&E) in line with other T&E requirements in 10 CFR part 35. The manufacturers stated, during the same ACMUI meeting, that training under the supervision of a manufacturer representative should remain as a T&E pathway because their representatives are highly knowledgeable about their devices. The NRC agrees with the manufacturers that the individual who provides the training in the operation of the device should be knowledgeable about the device, and this could include a manufacturer representative as well as the licensees’ personnel. The proposed licensing guidance still requires the physician to receive training on the operation of the device. However, the E:\FR\FM\07NON1.SGM 07NON1 Federal Register / Vol. 82, No. 214 / Tuesday, November 7, 2017 / Notices ethrower on DSK3G9T082PROD with NOTICES clinical experience a physician received during the 3 patient cases should include more than operation of the device. At a minimum, the clinical experience should also include evaluation of dose and activity of Y–90 microspheres to be administered to each treatment site, calculating and measuring the activity and safely preparing the Y–90 microspheres to be delivered, using administrative controls to prevent a medical event, and following up and reviewing each patient’s case history. During the ACMUI meeting, the ACMUI recommended that this type of training be provided by someone with defined medical experience, but left it up to the NRC to decide what medical experience would be necessary. As this T&E is specific to patient care and patient follow-up, the proposed licensing guidance recommends this type of training be provided by an AU for each type of Y–90 microsphere for which the individual is seeking AU status, similar to how other modalities are regulated in 10 CFR part 35. Additionally, changing the criteria would not preclude the manufacturer representatives from providing training, as is normally done for other therapies. III. Request for Comments The NRC is requesting comments on the proposed licensing guidance, entitled, ‘‘Yttrium-90 Microsphere Brachytherapy Sources and Devices TheraSphere® and SIR-Spheres® Licensing Guidance, Revision 10.’’ While the NRC is requesting comments on the entirety of the proposed guidance, the NRC is specifically seeking comments on several sections. (1) Recommended Minimum Clinical Experience: Due to the complexity of delivery of Y–90 microspheres, the licensing guidance historically and currently recommends that a prospective AU demonstrate he or she has clinical experience with the device. The current recommendation is that 3 patient cases for each type of microsphere should be completed for each prospective authorized user prior to approval. This recommendation is similar to requirements in other therapy modalities, such as section 35.390 of title 10 of the Code of Federal Regulations (10 CFR). The NRC is seeking specific comments on whether 3 patient cases provide adequate clinical experience for a physician to gain AU status for Y–90 microspheres. (2) Adding Authorization for Other Microsphere Type: The NRC is seeking comments to determine additional training needed when an AU who is already authorized to use one type of VerDate Sep<11>2014 17:29 Nov 06, 2017 Jkt 244001 microsphere requests authorization for use of another type of microsphere. For instance, are 3 additional cases for the other type of microsphere necessary for the AU to gain the knowledge to safely administer the new microsphere, or should the number of cases be left to the discretion of the supervising AU? (3) Written Attestation from Preceptor: Historically, the NRC has not required a written attestation, signed by a preceptor AU, because there was not a sufficient number of AUs to supervise the training and sign the written attestation. However, given that the NRC and Agreement States have licensed Y– 90 microsphere brachytherapy AUs for over 10 years, the NRC is seeking comments to determine if there is anything unique about Y–90 microsphere brachytherapy compared to other types of manual brachytherapy that would obviate the need for a written attestation. (4) Clinical Experience under the Supervision of a Manufacturer Representative: The proposed licensing guidance removes the alternate pathway, which allows an individual to become an AU for Y–90 microsphere brachytherapy prior to completing any patient cases if the applicant commits that the first three patient cases completed by that AU will be hands-on and supervised in the physical presence of a manufacturer representative. This alternate pathway remained in the licensing guidance for several years because there were a limited number of AUs who were authorized for each type of Y–90 microsphere, which made it difficult for physicians who were seeking authorization to complete the necessary clinical experience described in Section B under the supervision of another AU already authorized for the use of Y–90 microspheres. The NRC is seeking comments on whether completing the recommended clinical experience under the supervision of AU(s) authorized for the type of microsphere for which the new physician is seeking authorization still presents an undue burden on physicians. Further, the NRC is seeking comments on whether any unique characteristics of Y–90 microsphere brachytherapy warrant continuation of this alternate training pathway. Additionally, the NRC is seeking comments on whether finding licensed facilities at which the physicians could complete this clinical experience would be difficult. (5) Timeliness for Completion of InVivo Cases: The NRC is seeking comments on whether the proposed one in-vivo case prior to treating patients would be appropriate if 6 months has PO 00000 Frm 00061 Fmt 4703 Sfmt 9990 51657 passed to ensure recentness of training or whether this proposal could potentially lower licensee’s safety standards for the patients being treated. (6) Medical Event Definition: The NRC is seeking comments on the definition of medical events (ME) for Y–90 microspheres as provided in the proposed guidance. A primary purpose of ME reporting is to identify the cause of the event in order to correct them and prevent their recurrence. In the last 2 years there have been several MEs reported where the administration of the Y–90 results in dose or activity to the lobe opposite the lobe documented in the written directive. The working group was informed that in some instances, the AU may determine in the interventional radiology suite that they may be unable to deliver the amount of Y–90 microspheres to the intended lobe, but still wish to perform the treatment knowing some dose or activity may go to the lobe opposite the lobe documented in the written directive. The NRC is seeking specific comments on whether the delivery of Y–90 microspheres can be controlled to a specific lobe or location as described in the written directive and, if not, whether flexibility in the written directive is necessary to avoid reporting of events that cannot be controlled using the current technology. If flexibility is necessary, the NRC is seeking comments on whether the use of dose or activity ranges in the written directive or an ability to change the written directive in the interventional radiology suite prior to administering the Y–90 microspheres would be adequate. This type of revision could be made verbally by the AU, as long as the revision is documented in writing and signed by the AU within 24 hours of providing the revision verbally, consistent with other uses in 10 CFR part 35. Dated at Rockville, Maryland, this 1st day of November, 2017. For the U.S. Nuclear Regulatory Commission. Daniel S.

II. Background

    The NRC is requesting public comment on the draft licensing 
guidance entitled ``Yttrium-90 Microsphere Brachytherapy Sources and 
Devices TheraSphere[supreg] and SIR-Spheres[supreg] Licensing 
Guidance.'' This draft would be revision 10 to this licensing guidance. 
The licensing guidance provides medical use applicants with an 
acceptable means of satisfying the requirements for a license for the 
use of TheraSphere[supreg] and SIR-Spheres[supreg] and is not intended 
to be the only means of satisfying the requirements for a license. The 
licensing guidance provides the NRC with a set of standard criteria for 
evaluating a license application, although an applicant may submit 
alternative information and commitments for review by the NRC staff to 
make a licensing determination unless the information is specifically 
required by regulation. This guidance will also be available for 
voluntary use by Agreement States.
    The licensing guidance for Y-90 microsphere brachytherapy was 
initially published in October 2002 and subsequently revised in 2004, 
2007, 2008, 2011, 2012, and 2016. Following years of using the current 
licensing guidance, the NRC staff, stakeholders, and the Advisory 
Committee on the Medical Uses of Isotopes (ACMUI) have identified 
numerous issues that need to be addressed. A working group comprised of 
Agreement State representatives and NRC staff was formed to address 
identified issues. The document has been revised to significantly 
update the criteria for training and experience, medical event 
reporting, inventory requirement specifications, and waste disposal 
issues. The revised guidance document also provides new information 
regarding cremation and autopsy.
    As described in the draft licensing guidance, the NRC is 
recommending removal of the alternate, manufacturer provided clinical 
training pathway to complete the training and experience criteria 
listed in Section B of the training and experience section of the 
licensing guidance. During an ACMUI meeting on October 7, 2016 
(ML16357A688), the ACMUI recommended that the NRC leave this alternate 
pathway in the Y-90 microsphere licensing guidance to allow access to 
Y-90 microsphere brachytherapy in areas where there may not already be 
approved AUs to supervise new physicians. However, after licensing Y-90 
microspheres under 10 CFR 35.1000 for over 10 years, there should be 
substantial facilities and AUs available to offer training for Y-90 
microspheres, similar to other therapeutic modalities, and therefore 
this pathway should be removed to bring Y-90 microsphere brachytherapy 
training and experience (T&E) in line with other T&E requirements in 10 
CFR part 35.
    The manufacturers stated, during the same ACMUI meeting, that 
training under the supervision of a manufacturer representative should 
remain as a T&E pathway because their representatives are highly 
knowledgeable about their devices. The NRC agrees with the 
manufacturers that the individual who provides the training in the 
operation of the device should be knowledgeable about the device, and 
this could include a manufacturer representative as well as the 
licensees' personnel. The proposed licensing guidance still requires 
the physician to receive training on the operation of the device. 
However, the

[[Page 51657]]

clinical experience a physician received during the 3 patient cases 
should include more than operation of the device. At a minimum, the 
clinical experience should also include evaluation of dose and activity 
of Y-90 microspheres to be administered to each treatment site, 
calculating and measuring the activity and safely preparing the Y-90 
microspheres to be delivered, using administrative controls to prevent 
a medical event, and following up and reviewing each patient's case 
history. During the ACMUI meeting, the ACMUI recommended that this type 
of training be provided by someone with defined medical experience, but 
left it up to the NRC to decide what medical experience would be 
necessary. As this T&E is specific to patient care and patient follow-
up, the proposed licensing guidance recommends this type of training be 
provided by an AU for each type of Y-90 microsphere for which the 
individual is seeking AU status, similar to how other modalities are 
regulated in 10 CFR part 35. Additionally, changing the criteria would 
not preclude the manufacturer representatives from providing training, 
as is normally done for other therapies.

III. Request for Comments

    The NRC is requesting comments on the proposed licensing guidance, 
entitled, ``Yttrium-90 Microsphere Brachytherapy Sources and Devices 
TheraSphere[supreg] and SIR-Spheres[supreg] Licensing Guidance, 
Revision 10.'' While the NRC is requesting comments on the entirety of 
the proposed guidance, the NRC is specifically seeking comments on 
several sections.
    (1) Recommended Minimum Clinical Experience: Due to the complexity 
of delivery of Y-90 microspheres, the licensing guidance historically 
and currently recommends that a prospective AU demonstrate he or she 
has clinical experience with the device. The current recommendation is 
that 3 patient cases for each type of microsphere should be completed 
for each prospective authorized user prior to approval. This 
recommendation is similar to requirements in other therapy modalities, 
such as section 35.390 of title 10 of the Code of Federal Regulations 
(10 CFR). The NRC is seeking specific comments on whether 3 patient 
cases provide adequate clinical experience for a physician to gain AU 
status for Y-90 microspheres.
    (2) Adding Authorization for Other Microsphere Type: The NRC is 
seeking comments to determine additional training needed when an AU who 
is already authorized to use one type of microsphere requests 
authorization for use of another type of microsphere. For instance, are 
3 additional cases for the other type of microsphere necessary for the 
AU to gain the knowledge to safely administer the new microsphere, or 
should the number of cases be left to the discretion of the supervising 
AU?
    (3) Written Attestation from Preceptor: Historically, the NRC has 
not required a written attestation, signed by a preceptor AU, because 
there was not a sufficient number of AUs to supervise the training and 
sign the written attestation. However, given that the NRC and Agreement 
States have licensed Y-90 microsphere brachytherapy AUs for over 10 
years, the NRC is seeking comments to determine if there is anything 
unique about Y-90 microsphere brachytherapy compared to other types of 
manual brachytherapy that would obviate the need for a written 
attestation.
    (4) Clinical Experience under the Supervision of a Manufacturer 
Representative: The proposed licensing guidance removes the alternate 
pathway, which allows an individual to become an AU for Y-90 
microsphere brachytherapy prior to completing any patient cases if the 
applicant commits that the first three patient cases completed by that 
AU will be hands-on and supervised in the physical presence of a 
manufacturer representative. This alternate pathway remained in the 
licensing guidance for several years because there were a limited 
number of AUs who were authorized for each type of Y-90 microsphere, 
which made it difficult for physicians who were seeking authorization 
to complete the necessary clinical experience described in Section B 
under the supervision of another AU already authorized for the use of 
Y-90 microspheres. The NRC is seeking comments on whether completing 
the recommended clinical experience under the supervision of AU(s) 
authorized for the type of microsphere for which the new physician is 
seeking authorization still presents an undue burden on physicians. 
Further, the NRC is seeking comments on whether any unique 
characteristics of Y-90 microsphere brachytherapy warrant continuation 
of this alternate training pathway. Additionally, the NRC is seeking 
comments on whether finding licensed facilities at which the physicians 
could complete this clinical experience would be difficult.
    (5) Timeliness for Completion of In-Vivo Cases: The NRC is seeking 
comments on whether the proposed one in-vivo case prior to treating 
patients would be appropriate if 6 months has passed to ensure 
recentness of training or whether this proposal could potentially lower 
licensee's safety standards for the patients being treated.
    (6) Medical Event Definition: The NRC is seeking comments on the 
definition of medical events (ME) for Y-90 microspheres as provided in 
the proposed guidance. A primary purpose of ME reporting is to identify 
the cause of the event in order to correct them and prevent their 
recurrence. In the last 2 years there have been several MEs reported 
where the administration of the Y-90 results in dose or activity to the 
lobe opposite the lobe documented in the written directive. The working 
group was informed that in some instances, the AU may determine in the 
interventional radiology suite that they may be unable to deliver the 
amount of Y-90 microspheres to the intended lobe, but still wish to 
perform the treatment knowing some dose or activity may go to the lobe 
opposite the lobe documented in the written directive. The NRC is 
seeking specific comments on whether the delivery of Y-90 microspheres 
can be controlled to a specific lobe or location as described in the 
written directive and, if not, whether flexibility in the written 
directive is necessary to avoid reporting of events that cannot be 
controlled using the current technology. If flexibility is necessary, 
the NRC is seeking comments on whether the use of dose or activity 
ranges in the written directive or an ability to change the written 
directive in the interventional radiology suite prior to administering 
the Y-90 microspheres would be adequate. This type of revision could be 
made verbally by the AU, as long as the revision is documented in 
writing and signed by the AU within 24 hours of providing the revision 
verbally, consistent with other uses in 10 CFR part 35.

    Dated at Rockville, Maryland, this 1st day of November, 2017.
