For Cause.  Each Party shall have the right to terminate this Agreement upon written notice to the other Party if, after receiving written notice of a material breach of this Agreement, the breaching Party fails to cure such breach within sixty (60) days from the date of such notice.


  (c)

Due to Bankruptcy.    Each Party shall have the right to terminate this Agreement upon written notice to the other Party if the other Party becomes subject to an administration order or makes any voluntary arrangements with its creditors, goes into liquidation (except for the purposes of amalgamation or restructuring and so that the resulting company effectively agrees to be bound by or assume the obligations imposed on that party under this Agreement), or otherwise ceases to carry on business.


8.3

Effect of Termination.


  (a)

Expiration or termination of this Agreement shall not affect any accrued rights or obligations of either Party. Such termination or expiration shall not relieve either Party from obligations that are expressly indicated to survive termination or expiration of the Agreement. Upon any such expiration or termination, each Party shall return to the other Party any Confidential Information provided to it by such Party under this Agreement; except for one (1) copy of any documentation of such Confidential Information, which shall be kept solely for legal archival purposes.


  (b)

If LICR terminates this Agreement pursuant to Section 8.2(b), KaloBios terminates this Agreement pursuant to Section 8.2(a) or if either Party terminates the Agreement pursuant to Section 8.2(c), then subject to paragraph(c) hereof:


  (i)

the license granted under Section 2.1 shall automatically terminate and revert to LICR; and


  (ii)

the Parties shall (upon LICR's written request) negotiate in good faith the commercially reasonable terms under which KaloBios would license and transfer


13.

[***] CONFIDENTIAL PORTIONS OF THIS DOCUMENT REDACTED AND SEPARATELY FILED WITH THE COMMISSION.


 

to LICR the data, documentation, regulatory filings and registrations relating to any Licensed Products generated by KaloBios, and the relevant rights therein.


  (c)

In the event that LICR terminates this Agreement pursuant to Section 8.2(b) or Section 8.2(c) and, prior to the date of termination, KaloBios has developed a Licensed Product and entered into a sub-license with respect to that Licensed Product, LICR will enter into an agreement with that sub-licensee under which LICR shall license the LICR Patent Rights to the sub-licensee on the terms and conditions set out in this Agreement. The effective date of such agreement shall be the date of termination.


8.4

Survival.  The provisions of Articles 1, 4, 5, 7, and 10; and Sections 3.5, 3.8, 8.3 and 8.4, of this Agreement shall survive expiration or termination of this Agreement for any reason (subject to any subsequent dates of termination referred to in such individual Articles and Sections).


9.

DISPUTE RESOLUTION.


9.1

Disputes.  The Parties recognize that disputes as to certain matters may from time to time arise which relate to either Party's rights and obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in Section 9.2, if and when such a dispute arises between the Parties.


9.2

Dispute Resolution Procedures.    If any dispute, claim or controversy of any nature arising out of or relating to this Agreement, including any action or claim based on tort, contract or statute, or concerning the interpretation, effect, termination, validity, performance and/or breach of this Agreement (each, a "Dispute"), arises between the Parties and the Parties cannot resolve such Dispute within thirty (30) days of a written request by either Party to the other Party, the Parties agree to refer the Dispute either to: (a) the chief scientific officer (or equivalent) of LICR and the chief scientific officer (or equivalent) of KaloBios for resolution (if such Dispute relates to scientific issues); or (b) to the head of business development (or equivalent) of LICR and the head of business development (or equivalent) of KaloBios for resolution (if such Dispute does not relate to scientific issues). If such officers of the Parties cannot resolve such Dispute within an additional thirty (30) days, then such Dispute shall be referred to the chief executive officer (or equivalent) of LICR and the chief executive officer (or equivalent) of KaloBios for resolution. After an additional thirty (30) days, if such officers have not succeeded in negotiating a resolution of the Dispute, then either Party may at any time thereafter seek to resolve such Dispute by arbitration or through a court of competent jurisdiction. Notwithstanding anything to the contrary, if any Dispute arises from either Party's rights or obligations under Article 4 (Intellectual Property) or Article 5 (Confidentiality), then a Party may seek equitable relief from a court of competent jurisdiction without needing to resort to the dispute resolution mechanism described above in this Section 9.2.

JOINT RESEARCH PROGRAM

Proposed EphrinA3 Project

Objective of Stage 1 (12months)

The objective of the project is to demonstrate the utility of EphA3 as a target for cancer therapy and to identify a therapeutic development candidate by July 2006.

Proposed Work Program


  1.1

Normal Tissue Expression

Published data suggests that EphA3 is expressed at low levels in some human tissues and may be highly expressed in adult retina. Mouse EphA3 gene knock-out mice show high perinatal mortality (75%) but adult mice appear normal. Antibody [***] cross-reacts with mouse and human EphA3 and therefore it should be possible to investigate PK and normal tissue binding of this antibody in normal mice. [***] is a murine g1 antibody i.e. has poor effector function. The evaluation of the ADCC and/or complement effects of an EphA3antibody on normal tissues requires an active isotype version. PK analysis can be obtained with the current form of the antibody in normal mice.


  1.1.1

Proposal Studies


a.

Pharmacokinetics and volume of distribution of [***] in normal mice at different antibody doses

b.

Confirmation of EphA3 expression in mouse retina and reactivity with [***] antibody

c.

Construction of [***] human g1 chimeric and evaluation for safety/tolerability in mice


  1.2

Tumor/Tumor blood vessel Expression

The current literature suggests that EphA3 is expressed in a wide variety of human tumors although expression may not be uniform. Many of these studies have been carried out using RT-PCR and reactivity should be confirmed by IHC. Published data suggests that EphA3 is expressed in: 44% (11/25) small cell lung cancer, 24% (10/41) non-small cell lung cancer, 58% (17/29) sarcomas and 31% (12/38) renal cell carcinomas. EphA3 is also strongly expressed in at least 20% melanomas. Expression in tumors of the hematopoietic system is variable.

The expression of EphA3 protein on human tumor cells needs to be analyzed as well as its expression on tumor blood vessels. This data should provide guidance on selection of clinical indications for early clinical trials.

  1.2.1

Proposed Studies


  a.

Production of antibody to formaldehyde-fixed EphA3

  b

Immunochemistry survey of human tumor samples

  c.

Laser capture and PCR to assess EphA3 expression on tumor blood vessels


  1.3

Anti-Tumor Effects In vivo

The anti-tumor activity of molecules that interfere with EphA3 activity suggest that both unconjugated and conjugated antibodies will have therapeutic effect in mouse models. The optimal form of an EphA3 targeted therapeutic will have to be determined.

Work by Lackman et al has shown anti-tumor activity of a [***] antibody conjugate and a [***] IgG dimer in a human tumor xenograft model in the mouse. Brantley et al have shown anti-tumor activity of an EphA3-Fc fusion protein in a xenograft of the 4T1 mammary cell line. The EphA3-Fc protein was shown to reduce vascular density and tumor volume. EphA2-Fc fusion protein was also active in these types of models. Antibodies to EphA2 have been reported to show anti-tumor activity in animal models. EphA2 is expressed on tumor cells and tumor vasculature and EphA2-Fc protein inhibits tumor angiogenesis.

The importance of EphA3 targeting of endothelial cells for anti-tumor activity needs to be investigated in addition to direct tumor cell effects. The development candidate will be expected to show anti-tumor activity in tumor xenograft models of EphA3 expressing and non-expressing human tumors. The indirect anti-tumor activity (against tumor cells not expressing EphA3) should be through tumor endothelial cell effects (angiogenesis).


  1.3.1

Proposed Studies


  a.

Produce chimeric [***] (human gl) monoclonal antibody

  b.

Produce chimeric [***]

  c.

Produce [***]

  d.

Produce chimeric [***]

  e.

Produce chimeric [***]

  f.

Evaluate molecules in human tumor xenografts in mice

  g.

Evaluate targeted killing of tumor vasculature/inhibition of angiogenesis


  1.4

Development Candidate

The mouse antibody [***] is a lead molecule. The antibody V-regions will be converted into human V-regions. The importance of valency, ephrin A5 and drug conjugates will be factored into the design of the development candidate. Optimization of effector functions will be considered.


  1.4.1.

Proposed Studies


  a.

Humaneer antibody [***]

  b.

Express in appropriate host cell and generate a manufacturing cell line

  c.

Demonstrate efficacy in appropriate xenograft models
