Rani Therapeutics Announces Positive Topline Results from Phase 1 Study of RT-102 in Osteoporosis

10 August 2022
  • RT-102 was generally well-tolerated, with no RaniPill™-related adverse events 
  • Bioavailability of PTH delivered via the RaniPill was found to be 300-400% greater than PTH delivered via subcutaneous injection 
  • Improved RaniPill design enabled 95% drug delivery success rate

Rani Therapeutics Holdings, Inc. (“Rani Therapeutics” or “Rani”) (Nasdaq: RANI), a clinical-stage biotherapeutics company focused on the oral delivery of biologics and drugs, today announced positive topline results from the single-ascending dose portion of its Phase 1 clinical study of RT-102, a RaniPill capsule containing a proprietary formulation of human parathyroid hormone (PTH) analog PTH (1-34) for the potential treatment of osteoporosis (“Study Part 1”). Study Part 1 achieved all of its endpoints, with RT-102 being generally well-tolerated and demonstrating high oral bioavailability of Rani’s PTH analog.

“I am delighted to share the results of Part 1 of our Phase 1 study of RT-102, which demonstrated not only that RT-102 was generally well-tolerated, but also that the bioavailability of PTH delivered using the RaniPill was greater than the bioavailability of PTH delivered subcutaneously in this study – specifically RT-102 delivered PTH with between 300-400% greater bioavailability than subcutaneous Forteo® (teriparatide) in the study. Based on these results, we believe RT-102 has the potential to be an effective oral treatment option for patients with osteoporosis comparable to the current injectable standard of care,” said Talat Imran, Chief Executive Officer of Rani. “Importantly, this marks the first results of our second Phase 1 clinical trial, following on the positive results we previously announced for RT-101, the RaniPill capsule containing octreotide. Our RaniPill platform has now been tested in more than 80 healthy volunteers, and the incremental enhancements we have made to the RaniPill design have further increased drug delivery success rate. We plan on sharing these results with the U.S. Food and Drug Administration and, subject to a successful IND filing, initiating a Phase 2 trial for RT-102 in the U.S. in 3Q 2023.”

The single-center, open label, Study Part 1 of RT-102 was conducted in Australia. The study evaluated the safety, tolerability, and pharmacokinetics (PK) of RT-102 in healthy adult female volunteers. Of the 39 Of the 39 participants, 15 were administered RT-102 containing a single 20μg dose of PTH and 14 were administered RT-102 containing a single 80μg dose of PTH, while a control group of 10 participants received a single 20μg subcutaneous injection (SC) of Forteo (teriparatide), a commercial formulation of PTH for SC administration. The endpoints of the study were safety and tolerability, and measurements of serum concentrations of RT-102 in healthy adult female volunteers.

Phase 1 Topline Results

Safety Data

  • RT-102 was generally well-tolerated, with no RaniPill-related adverse events (AEs) observed in study participants:
    • 0% (0/15) of participants dosed with RT-102 20μg experienced drug-related AEs.
    • 14% (2/14) of participants dosed with of RT-102 80μg experienced drug-related AEs.
    • 50% (5/10) of participants dosed with 20μg of Forteo SC experienced drug-related AEs.
    • There were no serious adverse events (SAEs) noted during Study Part 1.

Per protocol, in instances where the RaniPill capsule did not exit the stomach within 7 hours, participants were excluded from the study. Based on the exclusion criteria, three participants were excluded from Study Part 1, one of whom experienced bloating, and one additional subject was excluded due to vomiting the capsule intact. In all instances, the capsule remnants passed from all participants who ingested the RaniPill capsule.

Across our two clinical studies of the RaniPill platform (Phase 1 clinical study of RT-101, a RaniPill capsule containing octreotide, and Study Part 1 of RT-102), 81 subjects received the RaniPill capsule and no RaniPill-related AEs were observed in participants in the studies.


  • Oral RT-102 (20μg and 80μg) delivered PTH with 300%-400% greater bioavailability than PTH delivered by Forteo SC (20μg).
  • RT-102 20μg delivered PTH with lower, more sustained peak serum levels and higher area under the curve (AUC) than Forteo SC 20μg.
 Forteo SC 20μgRT-102 20μgRT-102 80μg

 AUC (h*pg/mL)126 ± 64342 ± 362600 ± 649
 Relative BA (5)N/A~300%~400%
  • Although the Study Part 1 did not include a head-to-head comparison with abaloparatide (Tymlos®), RT-102 80μg demonstrated a PK profile similar to abaloparatide at 80μg as reported in the package insert for Tymlos. Specifically:
    • abaloparatide at 80μg has a Cmax of 812 ± 118, while RT-102 80μg had a Cmax of 971 ± 223.
    • abaloparatide at 80μg has an AUC of 1622 ± 641, while RT-102 80μg had an AUC of 2600 ± 649.

Device Performance

  • Two versions of the RaniPill were used during Study Part 1: Version C, which was used in Rani’s Phase 1 study of octreotide (which also utilized a Version A and Version B); and Version D, the latest iteration of the RaniPill.
  • New RaniPill Version D demonstrated a higher drug delivery success rate than Version C:
    • 95% (20/21) of participants received successful drug delivery when ingesting RaniPill Version D.
    • 75% (6/8) of participants received successful drug delivery when ingesting RaniPill Version C.

The device performance analysis does not include participants excluded from the study per protocol, as drug delivery was not measured in such participants.

Rodent Study

In addition to Study Part 1 of RT-102, we also conducted a 6-week pharmacodynamic (PD) study of the RT-102 drug substance (DS) PTH (1-34) to evaluate the effect of daily RT-102 DS intraperitoneal (IP) injections on bone mineral density (BMD) in a rodent model of osteoporosis. The study compared two control groups of rodents undergoing sham surgery (N=10) and ovariectomy (OVX) (N=10) receiving no drug, to three OVX groups each dosed with 5 mcg/kg per day of either RT-102 DS (N=10), teriparatide (N=10), or abaloparatide (N=10).

The study found that, following six weeks of treatment:

  • RT-102 DS increased BMD in a rat model of osteoporosis.
  • RT-102 DS delivered via the RaniPill IP route of administration was biologically active comparable to SC injected PTH analogs.
