- The Global Perceived Effect (GPE) of the use of pilocarpine drops at t= 2, t= 4, t= 8 and t = 12, as compared to placebo
- Oral Health-Related quality of life (OHRQoL) measured with the Geriatric Oral Health Assessment Index (GOHAI-NL) upon pilocarpine treatment at all time-points, as compared to placebo
- Health-Related Quality of Life (HRQoL) measured with the EQ-5D-5L questionnaire upon pilocarpine treatment at t = 0, t = 4, t = 8, and t = 12, as compared to placebo

- The durability of the effect of the use of pilocarpine drops at week 8 and 12 on xerostomia
- Possible side effects related to the intake of pilocarpine medication, measured from week 2 (t = 2, t = 4, t = 8, t = 12 weeks)
- The adherence rate of patients, measured at t = 2, t = 4, t = 8, t = 12 weeks
- Patients’ views on applicability of pilocarpine to reduce complaints of dry mouth, measured at t = 4, t = 8, t = 12 weeks

- The Global Perceived Effect (GPE) of the use of pilocarpine drops at t= 2, t= 4, t= 8 and t = 12, when compared to the placebo group
- Change in Oral Health-Related quality of life (OHRQoL) measured with the Geriatric Oral Health Assessment Index (GOHAI-NL) upon pilocarpine treatment at all time-points, when compared to the placebo group
- Change in Health-Related Quality of Life (HRQoL) measured with the EQ-5D-5L questionnaire upon pilocarpine treatment at t = 0, t = 4, t = 8, and t = 12, when compared to the placebo group
- Change in Patient-Reported Functional Status (PRFS) upon pilocarpine treatment at all time-points
- The durability of the effect of the use of pilocarpine drops at week 8 and 12 on xerostomia
- Possible side effects related to the intake of pilocarpine medication, measured from week 2 (t = 2, t = 4, t = 8, t = 12 weeks)
- The adherence rate of patients, measured at t = 2, t = 4, t = 8, t = 12 weeks
- Patients’ views on applicability of pilocarpine to reduce complaints of dry mouth, measured at t = 4, t = 8, t = 12 weeks
- The cost-effectiveness of pilocarpine treatment, measured at t = 0, t = 4, t = 8, t = 12 weeks

- Reason
- Medicinal Product related
- Explanation
- After the blinded four week active study period, where patients receive pilocarpine or placebo as IMP, every participant is offered an eight week unblinded extension treatment period with off-label pilocarpine eye drops (Minims). The off-label pilocarpine was not delivered as IMP but as regular medication via the patients' pharmacy. This is reported as serious breach.
- Follow-up measures
- Actions taken
As soon as we became aware, the METC and the Grant Supplier (ZonMw) were informed (December 4 2023). The METC discussed the issue December 6, we received an answer December 8 2023. Based on the answer of the METC the inclusion was set on hold December 6.
Planned actions
A substantial amendment will be submitted: Study stop after 4 weeks (this is the primary outcome measure) instead of 12 weeks; (secondary) measurements at 8 and 12 weeks will no longer be assessed.
Patients who want to make use of off-label pilocarpine treatment after 4 weeks will be advised to contact their general practitioner. - Benefit-risk balance changed

- Justification
- • Incorrect prescribing as the reason for the serious breach must be taken into account in the CTIS notification (in a update on this Serious Breach)
Toelichting:
Gaarne de melding in CTIS aanpassen door de onderzoeker. De oorzaak van de serious breach was het foutief (afwijkend t.o.v. het studieprotocol) regulier voorschrijven (pilocarpine medicatie op recept onherkenbaar als onderdeel van een studie) i.p.v. het voorschrijven van het open label IMP en het trialrecept in te leveren bij de clinical trial unit. Deelnemers werden tevens door de studiearts foutief verwezen naar een reguliere apotheek i.p.v. de clinical trial unit van het ziekenhuis.
• Request advice from one or more committee DB members
• The committee requests an approval of the Substantial Modification with removal of the extension phase before the study can start again.
Graag verwijs ik u ook nog naar de separate email correspondentie d.d. 13-12-2023 waarin gevraagd is deelnemers die nu nog in het onderzoek zitten te informeren over het feit dat zij niet kunnen doorstromen/participeren in deel II (optionele fase) van het onderzoek (week 5 t/m 12).
• Participants currently on IMP treatment need to be informed that the extension phase will be canceled and an impact-analysis should be written, in which the consequences for participant’s insurance, absence of drug accountability, inappropriate labeling, and the risks of a different dosage form (multidose dropper bottles versus single-use minims) must be discussed.
Aanvullend:
De commissie wil u graag attenderen op de regelgeving van regulier off-label voorschrijven, waarbij de basis is dat iets verdisconteerd dient te zijn in een richtlijn en waarvan de meerwaarde reeds is aangetoond t.o.v. een geregistreerd alternatief.
