`
`PART III: THREE-YEAR EXCLUSIVITY FOR NDA'S AND SUPPLEMENTS
`
`To qualify for three years of exclusivity, an application or
`supplement must contain "reports of new clinical investigations
`(other than bioavailability studies) essential to the approval of
`the application and conducted or sponsored by the applicant."
`This section should be completed only if the answer to PART II,
`Question 1 or 2, was "yes."
`'
`
`1. Does the application contain reports of clinical
`investigations?
`(The Agency interprets "clinical
`investigations" to mean investigations conducted on humans
`other than bioavailability studies.)
`If the application
`contains clinical investigations only by Virtue of a right of
`reference to clinical investigations in another application,
`answer "yes," then skip to question 3(a).
`If the answer to
`3(a)
`is "yes" for any investigation referred to in another
`application, do not complete remainder-of summary for that
`investigation.

`
`2. A clinical investigation is "essential to the approval" if the
`Agency could not have approved the application or supplement
`without relying on that investigation. Thus,
`the
`investigation is not essential to the approval if 1) no
`clinical investigation is necessary to support the supplement
`or application in light of previously approved applications
`(i.e.,
`information other than clinical trials, such as
`bioavailability data, would be sufficient to provide a basis

`
`Office/Division Director Memo for Cubicin (daptomycin for injection)
`
`Indication: Complicated Skin and Soft Tissue Infections
`
`September 11, 2003
`
`The pre-clinical and clinical reviewers have done an excellent job of detailing the issues
`in their disciplines and in the safety and efficacy of this product. There is clearly a need
`for additional products to treat severe infections due to Gram-positive organisms
`including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant
`enterococcal (VRE) infections. This submission addresses some but not all ofthese issues
`and needs.
`l will only very briefly mention preclinical findings, efficacy and safety, and
`then identify what I see as currently unresolved issues.
`
`Preclinical:
`
`The major target organs of daptomycin toxicity toxicity in rat, dog, and monkey were
`muscle and peripheral nerves. Muscle damage consisted of muscle degeneration/
`regeneration and usually resolved within 1 month of cessation oftreatment. Muscle
`changes were sometimes accompanied by increases in creatine phosphokinase (CPK).
`Peripheral nerve damage occurred at higher doses and included loss of patellar/gag
`reflexes, loss ofpain perception, decreases in nerve conduction velocity, and axonal
`degeneration. The dosing interval (quh v. q24h) appeared to play a role in the
`development of muscle toxicity in animals, favoring q24h.
`
`Efficacy:
`
`Two multicenter, multinational, randomized, active control studies were conducted by
`Cubist in hospitalized patients with serious skin infections, with over 500 patients
`receiving daptomycin.
`I agree with the overall conclusions as stated in the Medical
`Officer Reviews. In these two adequate and well-controlled trials in complicated skin
`and skin structure infections (cSSSI), daptomycin performed in a similar fashion to
`appropriate controls. Infections included major abscesses, post-surgical wound
`
`infections, and infected ulcers. The data were insufficient to demonstrate efficacy in
`Analyses of various subgroups based upon age, sex, underlying
`disease and severity ofinfection did not show any convincing trend favoring either
`daptomycin or control. Analyses looking at efficacy based upon infecting organism also
`showed comparability across the relevant organisms. Sufficient data exist to support
`clinical efficacy for cSSSI due streptococci of Groups A, B, and C. While a breakpoint
`of 0.5 uyml. can be justified by strict application ofa Mngo plus one rule, a l ug/mL
`breakpoint can be supported by the MIC distribution data, a lack of resistance, and
`clinical efficacy data. Sufficient data exist to include MRSA with the indication of
`cSSSI. Not surprisingly, however, there were insufficient numbers of VRE to include
`.. “q—~.--
`
`
`
`this organism with the indication. There were sufficient data to include vancomycin-
`susceptible Enrerococcusfaecalis.
`
`Safety:
`
`I agree with the
`Clinical data for over 1400 patients given daptomycin were evaluated.
`overall conclusions as stated in the reviews and as described in product labeling. The
`overall safety profile ofthis product is similar to that ofthe control regimens. Skeletal
`muscle appears to be a target organ for toxicity as demonstrated in pre-clinical studies as
`well as in the clinical trials, and this is likely to be a problem that will require on-going
`assessment and potential re-evaluation in the post-mfrketing period. The manifestations
`ofthis are both laboratory and clinical. The overall difference in frequency of CPK
`elevations is not great between daptomycin and control, but higher-grade elevations are
`slightly more common on daptomycin. There have been several cases with clinical
`symptoms including one with myositis that resolved after therapy was discontinued. At
`present, there is no information regarding risk factors such as age or baseline CPK that
`might predispose to this toxicity. Since the overall number of patients that have been '
`exposed to daptomycin is in the 1000+ range, it is likely that the frequency and severity
`ofthis toxicity and potential antecedent factors will not be better defined until actual use
`in practice, in conjunction with post marketing studies in vivo and in vitro.
`
`Both pre-clinical and some early clinical trial data suggest that peripheral neuropathy
`may be an adverse event associated with daptomycin use. The pre-clinical information
`suggested that higher exposures were necessary for this toxicity to be expressed and the
`Phase 3 clinical trials did not show clear—cut evidence ofthis toxicity. These latter studies
`were conducted in a patient population with underlying diabetes and/or significant limb
`infection that could make such assessment difficult. Again post-marketing information
`may better define the significance ofthis toxicity.
`
`To date, neither liver nor cardiac electrophysiologic (Q-T prolongation) toxicity appears
`to be an issue. There was no excess of transaminase increases or alkaline phosphatase
`elevations in daptomycin-treated patients.
`
`Unresolved Issues:
`
`There is a continued need for new products to treat serious Gram positive infections, and
`daptomycin, with its unique mechanism of action and its spectrum of activity, would
`appear to be an important new product in the therapeutic armamentan'um. Tempering this
`enthusiasm are the results of studies conducted in other serious conditions beyond the
`current indication. In a pilot study of patients with either Staphylococcus aureus
`bacteremia or actual endocarditis conducted by Lilly, the original developer of this
`product, unexpectedly lower efficacy for daptomycin was seen. It would appear that
`lower peak levels in the BID dosing regimen used in this trial and possibly insufficient
`penetration into vegetations with the may have contributed to this finding. In a
`Community Acquired Pneumonia trial conducted by Cubist daptomycin performed also
`performed less well than would have been expected. It is believed that reduced
`.__-~_.,
`
`
`
`penetration into the lung was a factor in these results. The pneumonia data was
`sufficiently convincing that a statement appears in the Indications and Usage section of
`the product label that daptomycin is not indicated for community acquired pneumonia.
`
`Additional study ofdaptomycin in serious illness is clearly necessary. A small study of
`right sided bacterial endocarditis using the to be approved 4 mg/kg OD regimen is
`currently underway. Results of this study are to be monitored after the first thirty patients
`are enrolled. Ideally it would also be appropriate to evaluate the usefulness ofthis
`- product in serious enterococcal infections. The company does not currently have such a
`trial underway and the possibility of doing this should be the subject of further
`discussion.
`
`Finally, the optimal dose for patients with renal insufficiency needs to be determined.
`Dose adjustment for patients with CrCL of: SOmL/min, including patients on dialysis
`(hemodialysis and CAPD), needs to be determined in a Phase 4 study. Cubist has agreed
`to perform such a study. In the meantime, the basis for current dosing recommendations
`rests upon the clinical efficacy and safety data in patients with normal renal function
`combined with limited data in subjects and patients with renal impairment.

`MEMO OF FILING MEETING
`
`DATE: February 13, 2003
`
`BACKGROUND
`
`The Applicant submitted a New Drug Application (NDA) on December 20, 2002 for Cidecin® (daptomycin
`for injection) for the treatment of complicated Skin and Skin Structure Infections (cSSSI) including those
`complicating diabetic foot and decubitus ulcers caused by susceptible strains of the' following Gram-positive
`microorganisms: Staphylococcus aureus (including methicillin-resistant strains), Streptococcus pyogenes,
`Sn'eptococcus ago/actiae, Streptococcus dysgalacn'ae subsp. equisimilis, Enterococcusfaecilis (vancomycin-
`susceptible strains only)
`,__..
`
`The daptomycin clinical program consisted of studies conducted by both Eli Lilly and Company
`(Lilly) and Cubist Pharmaceuticals, Inc. (Cubist). Lilly conducted primarily Phase I single and
`multiple dose safety and pharmacokinetic studies and a small Phase 2 program which consisted of
`two studies. Cubist obtained worldwide marketing rights for daptomycin from Lilly and filed its own
`IND application in December, 1998. The pre-clinical data previously generated by Lilly was used to
`support Cubist's initial Phase 2 and 3 clinical trials. Cubist has modified Lilly‘s clinical strategy of
`administering divided daily doses of daptomycin to emphasize once-daily dosing of daptomycin. This
`was done based on preclinical studies, clinical data analysis, and modeling that show that once-daily
`dosing maximizes antibacterial efficacy while minimizing adverse effects,
