I'm not aware of any, but the following SQL could be used as the basis of such a report.

select reminder.act_id reminder_id,
       reminder.activity_end_time due_date,
       customer.entity_id customer_id,
       customer.name customer_name,
       patient.entity_id patient_id,
       patient.name,
       reminder_type.entity_id reminder_type_id,
       reminder_type.name reminder_type_name
from acts reminder
join participations ppat
    on reminder.act_id = ppat.act_id
        and ppat.arch_short_name = 'participation.patient'
join entities patient
    on ppat.entity_id = patient.entity_id
join participations ptype
    on reminder.act_id = ptype.act_id
        and ptype.arch_short_name = 'participation.reminderType'
join entities reminder_type
    on ptype.entity_id = reminder_type.entity_id
join entity_relationships owner
    on owner.target_id = patient.entity_id
        and owner.arch_short_name = 'entityRelationship.patientOwner'
        and owner.active_end_time is null
join entities customer
    on owner.source_id = customer.entity_id    
where reminder.arch_short_name = 'act.patientReminder' and reminder.status = 'IN_PROGRESS'
    order by customer.name, patient.name, reminder_type.name, reminder.activity_end_time;
