NCT04196855

Brief Summary

Investigation into the use of teriparatide in the treatment of stress fractures. Primary outcome is healing on MRI, secondary outcomes are pain, time spent in rehabilitation and future stress fractures. This study will help the investigators understand how to treat stress fractures in the future.

Outcome Measures

Primary Outcomes (1)

  • Radiological healing.

    Radiological healing by 2 Grades or more, or to grade zero at 8 weeks.

    8 weeks.

Secondary Outcomes (7)

  • Radiological Healing

    8, 10, 12, 14, 16, 20, 24 weeks

  • Time from randomisation to assessed as 'Clinically Healed'.

    Twice weekly from date of radiologically healed stress fracture reported on MRI scan up to 24 weeks

  • Time to 'Healing' as a composite assessment.

    Up to 24 weeks.

  • Time from randomisation to discharge from rehabilitation.

    Up to 24 weeks

  • Pain symptoms on a visual analogue pain scale.

    Diary to be completed weekly and analysed as a change from baseline to 16 weeks (24 weeks in an unhealed fracture).

  • +2 more secondary outcomes

Other Outcomes (2)

  • P1NP response to teriparatide treatment.

    Base line then 4 weekly to week 16 - extorted to week 24 in the case of an unhealed fracture.

  • CTX response to teriparatide treatment.

    Base line then 4 weekly to week 16 - extorted to week 24 in the case of an unhealed fracture.

Study Arms (2)

Intervention - Teriparatide Treatment

EXPERIMENTAL

Teriparatide 20ug/day from confirmation of stress fracture for 16 weeks, with the potential to extend to 24 weeks if required.

Drug: Teriparatide

Control - Standard Care

NO INTERVENTION

Standard rehabilitation care with additional monitoring to assess healing.

Interventions

Terrosa 20 micrograms/80 microliters solution for injection. Each dose of 80 microliters contains 20 micrograms of teriparatide. One cartridge of 2.4 mL of solution contains 600 micrograms of teriparatide (corresponding to 250 micrograms per mL). Teriparatide, rhPTH(1-34), produced in E. coli, using recombinant DNA technology, is identical to the 34-N-terminal amino acid sequence of endogenous human parathyroid hormone.

Also known as: Terossa
Intervention - Teriparatide Treatment

Eligibility Criteria

Age18 Years - 40 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Signed informed consent form;
  • Participant must be aged 18 - 40 years inclusive;
  • Participant must have a lower limb stress fracture, either unilateral or bilateral, as confirmed via MRI scan;
  • Undergoing phase 1 or 2 training within an Army training establishment;
  • Blood Tests within reference range. Minor abnormalities will be assessed by the PI. Patients will still be entered if these are felt to be of no clinical importance.
  • Participants able to adhere to the visit schedule and protocol requirements.

You may not qualify if:

  • Hypersensitivity to the active Parathyroid Hormone substance or any of the excipients listed in the SmPC.
  • Pre-existing hypercalcaemia.
  • Patients with skeletal malignancies or bone metastases.
  • Any contraindications that would prevent the participant from undergoing an MRI scan.
  • Concurrent therapy that, in the investigators opinion, would interfere with the evaluation of the safety or efficacy of the study medication.
  • Pregnancy, suspected pregnancy or breastfeeding. Female participants must have a negative serum pregnancy test at screening and be willing and able to use a "highly effective" method of contraception, as per the Clinical Trial Facilitation Group (CTFG) guidance.
  • Severe renal impairment. Participants with moderate renal impairment will be treated with caution at the Principal Investigator's discretion and in accordance with the SmPC.
  • Metabolic bone diseases including hyperparathyroidism and Paget's disease of the bone.
  • Unexplained elevations of alkaline phosphatase.
  • Prior external beam or implant radiation therapy to the skeleton.
  • Patients participating in a concurrent drug trial.
  • Presentation with open epiphyses during the diagnostic MRI scan.
  • Participants with depression, as identified by completion of the Columbia-Suicide Severity Rating Scale (C-SSRS) at Baseline.
